ΓòÉΓòÉΓòÉ 1. Using Help ΓòÉΓòÉΓòÉ DoomEdit/PM (DEPM) allows you to request help in three ways: the Help Menu provides you with several options allowing you to request general help for some aspects of DEPM; help buttons on dialogs generally allow you to request help for the dialog; and F1 provides help for individual controls and menu choices. ΓòÉΓòÉΓòÉ 2. Keys Help ΓòÉΓòÉΓòÉ DoomEdit/PM (DEPM) is designed to be operated with a mouse. Although an attempt has been made to provide keyboard functionality, the very nature of DEPM prevents it from being operable by keyboard alone. Accelerator Keys: Esc discards the applicator. F1 provides help for individual controls and menu choices. F2 selects the Save PWAD menu item. F3 selects the Quit menu item. F5 selects the Check Map menu item. F6 selects the Thing menu item. F7 selects the Next thing menu item. F9 invokes the Texture Palette once the texture rendering process is complete. Delete delete the map object currently pointed at. Arrow Keys scroll the Map Window one "line" in the arrow's direction. Pg Up and Pg Dn scroll the Map Window one "page" up or down. Home and End scroll the Map Window one "page" left or right. Keys 1 through 0 set the zoom to a preset scale (10, 20, 30, 40, 50, 60, 70, 80, 90, 100). ΓòÉΓòÉΓòÉ 3. General Help for DoomEdit/PM ΓòÉΓòÉΓòÉ If you are new to DoomEdit/PM, please use the Tutorial to learn the basic methods behind map construction. DoomEdit/PM (DEPM) will run properly with a 256-colour display ONLY. It will not render textures properly on 16-colour displays. With 64k-colour drivers, DEPM renders nicely (wood comes out looking brown instead of slightly pinkish). The DEPM main window provides you with a menu bar allowing you to access: o the File menu o the Edit menu o the Locate menu o the Convert menu o the Preferences menu o the Help menu DEPM is intended to be operated with a mouse. If you want to try it with a keyboard only, I wish you the best of luck. ΓòÉΓòÉΓòÉ 3.1. The File Menu ΓòÉΓòÉΓòÉ The File menu provides you with a number of choices which allow you to perform operations at a PWAD level. These choices are: o New PWAD o Open PWAD... o Import PWAD... o Extras... o Save PWAD o Save PWAD as... o Save Palette o Memory Owned o Quit ΓòÉΓòÉΓòÉ 3.1.1. New PWAD ΓòÉΓòÉΓòÉ Selecting the New PWAD item will clear the current PWAD from memory. If the current PWAD has changed since it was saved, you will be asked if you are sure you want to clear it. ΓòÉΓòÉΓòÉ 3.1.2. Open PWAD... ΓòÉΓòÉΓòÉ Selecting the Open PWAD... item will allow you to load a PWAD into the editor. If the current PWAD has changed since it was saved, you will be asked if you are sure you want to clear it. The File Selection dialog will be displayed. If DEPM has a problem loading the specified file, you will be informed. Some editors produce PWADs with invalid or empty directory entries; when DEPM loads a file of this type, it will attempt to salvage all the resources for which valid directory entries exist. You will be informed when this happens. If Compress has been selected, DEPM will decompress the PWAD as it loads it. If you are unsure whether a PWAD has been compressed, it is always safest to load it with Compress selected. ΓòÉΓòÉΓòÉ 3.1.3. Import PWAD... ΓòÉΓòÉΓòÉ Selecting the Import PWAD item will allow you to load a PWAD into the editor, merging it with the PWAD already in memory. The File Selection dialog will be displayed. If DEPM has a problem loading the specified file, you will be informed. Some editors produce PWADs with invalid or empty directory entries; when DEPM loads a file of this type, it will attempt to salvage all the resources for which valid directory entries exist. You will be informed when this happens. If Compress has been selected, DEPM will decompress the PWAD as it loads it. If you are unsure whether a PWAD has been compressed, it is always safest to load it with Compress selected. If conflicts are detected between maps or extras, you will be asked if you want to replace the one in memory with the one being loaded. The File Selection dialog will be displayed again, to allow you to import another PWAD. Dismiss the File Selection dialog to end the import process. ΓòÉΓòÉΓòÉ 3.1.4. Extras... ΓòÉΓòÉΓòÉ Selecting the Extras... item will cause the Extras dialog to be displayed. This dialog allows you to delete or rename extras in memory. ΓòÉΓòÉΓòÉ 3.1.5. Save PWAD ΓòÉΓòÉΓòÉ Selecting the Save PWAD item will save the PWAD in memory to disk. If there are maps in your PWAD which need rebuilding, you will not be able to play them. If the map being displayed needs to be rebuilt, you will be given the option of doing so. ΓòÉΓòÉΓòÉ 3.1.6. Save PWAD As... ΓòÉΓòÉΓòÉ Selecting the Save PWAD as... item will save the PWAD in memory to disk under a new name. If there are maps in your PWAD which need rebuilding, you will not be able to play them. If the map being displayed needs to be rebuilt, you will be given the option of doing so. The File Selection dialog will be displayed, allowing you to select a new name for your PWAD. ΓòÉΓòÉΓòÉ 3.1.7. Save Palette ΓòÉΓòÉΓòÉ Once the palette rendering process is complete, you may elect to save the palette to disk to avoid re-rendering it each time you start up DEPM. This will require approximately 15 meg of disk space. Selecting the Save Palette item will cause the textures palette to be saved to disk. The textures palette will be reloaded the next time you start DEPM. ΓòÉΓòÉΓòÉ 3.1.8. Memory Owned ΓòÉΓòÉΓòÉ Selecting the Memory Owned item will cause DEPM to display the amount of memory it currently owns, and an estimated amount of memory used by the palette. This does not include memory used by the operating system for bitmaps and other resources which are not visible to DEPM. ΓòÉΓòÉΓòÉ 3.1.9. Quit ΓòÉΓòÉΓòÉ Selecting the Quit item (or dismissing DEPM by using the System Menu) will clear the current PWAD from memory, and will terminate DEPM. If the current PWAD has changed since it was saved, you will be asked if you are sure you want to clear it. ΓòÉΓòÉΓòÉ 3.2. The Edit Menu ΓòÉΓòÉΓòÉ The Edit menu provides you with a number of choices which allow you to perform operations at a map level. These choices are: o New map... o Edit map... o Alter ExMx... o Drop map... o Close map o Check map ΓòÉΓòÉΓòÉ 3.2.1. New Map... ΓòÉΓòÉΓòÉ Selecting the New map... item will allow you to create a new map from scratch. The Map Selection dialog will be displayed to allow you to select which map you wish to create a new map for. Once you have selected a target map, DEPM will enter Things Mode and the Editor and Map windows will be displayed. ΓòÉΓòÉΓòÉ 3.2.2. Edit Map... ΓòÉΓòÉΓòÉ Selecting the Edit map... item will allow you to edit an existing map. The Map Selection dialog will be displayed to allow you to select which map you wish to edit. Once you have selected a target map, DEPM will enter Things Mode and the Editor and Map windows will be displayed. ΓòÉΓòÉΓòÉ 3.2.3. Alter ExMx... ΓòÉΓòÉΓòÉ Selecting the Alter ExMx... item will allow you to change the target episode and map for a patched map. The Map Selection dialog will be displayed to allow you to select which map you wish to change. Once you have selected a source map, the Map Selection dialog will be displayed again, to allow you to select the target episode and map. Once the target map has been selected, the patched map will be moved. ΓòÉΓòÉΓòÉ 3.2.4. Drop Map... ΓòÉΓòÉΓòÉ Selecting the Drop map... item will allow you to delete a patched map from memory. The Map Selection dialog will be displayed to allow you to select which map you wish to drop. Once you have selected a map, the Map Selection dialog will be displayed again, to allow you to drop another map. This process continues until the Map Selection dialog is cancelled. ΓòÉΓòÉΓòÉ 3.2.5. Close Map ΓòÉΓòÉΓòÉ Selecting the Close map item will allow you to dismiss the Editor and Map windows. If the map needs to be rebuilt, you will be given the option of doing so. ΓòÉΓòÉΓòÉ 3.2.6. Check Map ΓòÉΓòÉΓòÉ Selecting the Check map item will cause DEPM to check your map for errors. The tests performed will depend on which mode the editor is in: o Things Mode o LineDefs Mode o Sectors Mode ΓòÉΓòÉΓòÉ 3.2.6.1. Things Mode ΓòÉΓòÉΓòÉ In Things Mode, DEPM looks for: o unknown thing types; o four (4) player starts; and o four (4) deathmatch starts. ΓòÉΓòÉΓòÉ 3.2.6.2. LineDefs Mode ΓòÉΓòÉΓòÉ In LineDefs Mode, DEPM looks for: o missing sidedefs; o missing or invalid textures; o incorrect flag settings; o no way to end the map; o unknown types; o DOOM2 linedefs in DOOM PWADs; and o missing sector tags. ΓòÉΓòÉΓòÉ 3.2.6.3. Sectors Mode ΓòÉΓòÉΓòÉ In Sectors Mode, DEPM looks for: o at least two (2) sectors; o sector closure; o unknown sector effects; o missing or invalid textures; o unreferenced sidedefs; and o unreferenced sectors. ΓòÉΓòÉΓòÉ 3.3. The Locate Menu ΓòÉΓòÉΓòÉ The Locate menu provides you with a number of choices which allow you to search a map for one of the following: o Free tag o Thing o Next thing ΓòÉΓòÉΓòÉ 3.3.1. Free Tag ΓòÉΓòÉΓòÉ Selecting the Free tag item will cause DEPM to find the first unused sector tag on the map, starting from "1". ΓòÉΓòÉΓòÉ 3.3.2. Thing ΓòÉΓòÉΓòÉ Selecting the Thing item will cause DEPM to display the Find Thing dialog. This dialog is used to define the type of thing you want to find, and will search for the first thing of that type. ΓòÉΓòÉΓòÉ 3.3.3. Next Thing ΓòÉΓòÉΓòÉ Selecting the Next thing item will cause DEPM to search for the next occurrence of the type of thing defined in the Find Thing dialog. ΓòÉΓòÉΓòÉ 3.4. The Convert Menu ΓòÉΓòÉΓòÉ The Convert menu provides you with two choices which allow you to convert textures between DOOM and DOOM2 maps: o Walls o Floors ΓòÉΓòÉΓòÉ 3.4.1. Walls ΓòÉΓòÉΓòÉ Selecting the Walls item will cause DEPM to display the Convert Textures dialog. This dialog allows you to find wall textures which do not exist in the IWAD, and to change them for the entire map. ΓòÉΓòÉΓòÉ 3.4.2. Floors ΓòÉΓòÉΓòÉ Selecting the Floors item will cause DEPM to display the Convert Textures dialog. This dialog allows you to find floor textures which do not exist in the IWAD, and to change them for the entire map. ΓòÉΓòÉΓòÉ 3.5. The Preferences Menu ΓòÉΓòÉΓòÉ The Preferences menu allows you to change some of the ways in which DEPM behaves. The following items can be selected: o Colours... o BSP tuning... o Map behavior... o Textures... o Autobuild o Compress o Backup o Palette ΓòÉΓòÉΓòÉ 3.5.1. Colours... ΓòÉΓòÉΓòÉ Selecting the Colours item will cause DEPM to display the Colour Preferences dialog. This dialog allows you to change the colours used to display the map on the Map Window. ΓòÉΓòÉΓòÉ 3.5.2. BSP Tuning... ΓòÉΓòÉΓòÉ Selecting the BSP tuning item will cause DEPM to display the BSP Tuning dialog. This dialog allows you to change the behavior of the node builder. ΓòÉΓòÉΓòÉ 3.5.3. Map Behavior... ΓòÉΓòÉΓòÉ Selecting the Map behavior item will cause DEPM to display the Map Behavior dialog. This dialog allows you to change the behavior of the Map Window. ΓòÉΓòÉΓòÉ 3.5.4. Textures... ΓòÉΓòÉΓòÉ Selecting the Textures... item will cause DEPM to display the Textures dialog. This dialog allows you to change the way textures are displayed in the SideDef Properties and Sector Properties dialogs. ΓòÉΓòÉΓòÉ 3.5.5. Autobuild ΓòÉΓòÉΓòÉ Selecting the Autobuild item will toggle DEPM's automatic node builder. When this item is checked, the node builder starts up whenever the map must be rebuilt, and it is safe to do so. When this item is not checked, the node builder does not start up unless you choose to do so during Close map, Save PWAD as..., or Save PWAD. ΓòÉΓòÉΓòÉ 3.5.6. Compress ΓòÉΓòÉΓòÉ Selecting the Compress item will toggle DEPM's compress mode. When this item is checked, DEPM will attempt to decompress PWADs when it loads them in, and compress PWADs when it saves them to disk. When this item is not checked, DEPM will not attempt to compress and decompress PWADs. Note that decompressing a PWAD which is not compressed will not cause a problem; the PWAD will be examined and will be left alone if it is not compressed. Loading a compressed PWAD with Compress not checked, however, will cause problems during linedef editing and node building. If you do not know whether a PWAD is compressed, it is always safest to load it in with Compress checked. ΓòÉΓòÉΓòÉ 3.5.7. Backup ΓòÉΓòÉΓòÉ Selecting the Backup item will toggle whether DEPM saves a copy of a PWAD to <name>.BWD when it loads it. When this item is checked, DEPM will back up any PWADs loaded. When this item is not checked, DEPM will not back up PWADs when it loads them. ΓòÉΓòÉΓòÉ 3.5.8. Palette ΓòÉΓòÉΓòÉ Selecting the Palette item will toggle whether DEPM renders textures into bitmaps when it runs. When this item is checked, DEPM will start a thread to render textures into bitmaps. This provides you with faster texture displays in the SideDef Properties and Sector Properties dialogs. When the rendering process completes, you will be able to invoke the Texture Palette to apply textures to linedefs quickly and easily. While the rendering thread runs, overall performance will be slightly more "choppy". When this item is not checked, DEPM will not render wall textures into bitmaps. This means that textures will be displayed more slowly, and the Texture Palette will be unavailable; however, it does have the advantage of smoother overall performance during the first 30 minutes of runtime. ΓòÉΓòÉΓòÉ 3.6. The Help Menu ΓòÉΓòÉΓòÉ The Help menu provides you with a number of choices which allow you to request assistance or information: o Using help o General help o Editor Window o Map Window o Tutorial o Product information ΓòÉΓòÉΓòÉ 3.6.1. Using Help ΓòÉΓòÉΓòÉ Selecting the Using help item will display an explanation of how to use OS/2's help facility. ΓòÉΓòÉΓòÉ 3.6.2. General Help ΓòÉΓòÉΓòÉ Selecting the General help item will display an explanation of the File menu; this panel can be used as a starting point for locating the information you require by using DEPM's hypertext help. ΓòÉΓòÉΓòÉ 3.6.3. Editor Window ΓòÉΓòÉΓòÉ Selecting the Editor Window item will display an explanation of the Editor Window; this panel can be used as a starting point for understanding how the Editor Window operates, and what all the controls and tools do in the various edit modes. ΓòÉΓòÉΓòÉ 3.6.4. Map Window ΓòÉΓòÉΓòÉ Selecting the Map Window item will display an explanation of the Map Window; this panel can be used as a starting point for understanding how the Map Window operates, and which drag-and-drop operations are supported in the various edit modes. ΓòÉΓòÉΓòÉ 3.6.5. Tutorial ΓòÉΓòÉΓòÉ Selecting the Tutorial item will cause DEPM to start up the DoomEdit/PM Tutorial as a separate process. This is intended to allow you to go through the Tutorial and to perform the activities described therein. ΓòÉΓòÉΓòÉ 3.6.6. Product Information ΓòÉΓòÉΓòÉ Selecting the Product information item will cause DoomEdit/PM to display version and copyright information about itself. ΓòÉΓòÉΓòÉ 4. The Extras Dialog ΓòÉΓòÉΓòÉ The Extras dialog allows you to delete or rename extras in a PWAD. The controls provided are: o Extras list box o All button o Delete button o Rename button o Help button o Exit button ΓòÉΓòÉΓòÉ 4.1.

The Map Selection Dialog ΓòÉΓòÉΓòÉ The Map Selection dialog will be displayed each time you are expected to tell DEPM which map you want to perform some action on. It contains the following controls: o Radio Buttons o OK Button o Help Button o Exit Button ΓòÉΓòÉΓòÉ 5.1. Radio Buttons ΓòÉΓòÉΓòÉ The radio buttons are used to select a map to perform an operation on. The label beside each radio button tells you which episode and map will be chosen when you select that button. Maps which are patched by the PWAD in memory will be displayed in black; maps which are not patched will be displayed in dark cyan. You cannot perform the following actions on maps which are not patched by the current PWAD: o Alter ExMx... o Drop map... ΓòÉΓòÉΓòÉ 5.2. OK Button ΓòÉΓòÉΓòÉ Press the OK button to perform the desired action on the selected map. ΓòÉΓòÉΓòÉ 5.3. Help Button ΓòÉΓòÉΓòÉ Press the Help button to display a help message about the Map Selection dialog. ΓòÉΓòÉΓòÉ 5.4. Exit Button ΓòÉΓòÉΓòÉ Press the Exit button to dismiss the Map Selection dialog. ΓòÉΓòÉΓòÉ 6. The Convert Textures Dialog ΓòÉΓòÉΓòÉ The Convert Textures dialog allows you to find textures which do not exist in the IWAD, and to change them for the entire map. It contains the following controls: o Textures Combo Box o OK Button o Abort Button o Help Button ΓòÉΓòÉΓòÉ 6.1. Textures Combo Box ΓòÉΓòÉΓòÉ The Textures combo box contains the valid textures in the IWAD. This control is used to select a replacement for the texture which was not found. ΓòÉΓòÉΓòÉ 6.2. OK Button ΓòÉΓòÉΓòÉ Press the OK button to change the current texture to the texture selected in the Textures Combo Box and to search for the next missing texture. ΓòÉΓòÉΓòÉ 6.3. Abort Button ΓòÉΓòÉΓòÉ Press the Abort button to dismiss the Convert Textures dialog. ΓòÉΓòÉΓòÉ 6.4. Help Button ΓòÉΓòÉΓòÉ Press the Help button to display a help message about the Convert Textures dialog. ΓòÉΓòÉΓòÉ 7. The Colour Preferences Dialog ΓòÉΓòÉΓòÉ The Colour Preferences dialog allows you to define which colours DEPM will use to display various components of the map in the Map Window. It contains the following controls: o Component List Box o Colours Value Set o OK Button o Abort Button o Help Button o Reset Button ΓòÉΓòÉΓòÉ 7.1. Component List Box ΓòÉΓòÉΓòÉ The Component list box displays the various components for which you may define the colour. Selection of an entry in this list box will set the Colours Value Set control to the current colour for that entry. ΓòÉΓòÉΓòÉ 7.2. Colours Value Set ΓòÉΓòÉΓòÉ The Colours value set control displays the colours you can use to display the various components. Selection of a colour in this control will set the colour to use when drawing the entry selected in the Component List Box. ΓòÉΓòÉΓòÉ 7.3. OK Button ΓòÉΓòÉΓòÉ Press the OK button to accept any changes you have made to the colours, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 7.4.

Reset Button ΓòÉΓòÉΓòÉ Press the Reset button to reset the colours to their default values. ΓòÉΓòÉΓòÉ 8. BSP Tuning Preferences ΓòÉΓòÉΓòÉ The BSP Tuning dialog allows you to change the way in which the node builder selects partition lines by changing the weight given to avoiding sidedef splits and to balancing the node tree. The weights are used against each other, so assigning a weight of 9 to both is the same as assigning a weight of 1 to both. The following controls are provided: o Split Weight Slider o Balance Weight Slider o OK Button o Abort Button o Help Button o Reset Button ΓòÉΓòÉΓòÉ 8.1. Split Weight Slider ΓòÉΓòÉΓòÉ The split weight slider allows you to control the weight given to avoiding sidedef splits when the node builder rebuilds the map. The valid range is 0 (no attempt to avoid splits) to 9 (avoid splits as much as possible). Assigning a high weight to avoiding splits will cut down on the number of sidedefs the game engine must display, and may prevent the HOM (Hall of Mirrors) effect in areas with a large number of two-sided sidedefs. ΓòÉΓòÉΓòÉ 8.2. Balance Weight Slider ΓòÉΓòÉΓòÉ The balance weight slider allows you to control the weight given to balancing the tree created when the node builder rebuilds the map. The valid range is 0 (no attempt to balance) to 9 (balance as much as possible). Assigning a high weight to balance may improve the performance of the game engine; be aware, however, that more balance may cause more splitting. ΓòÉΓòÉΓòÉ 8.3. OK Button ΓòÉΓòÉΓòÉ Press the OK button to accept any changes you have made to the Split Weight and Balance Weight sliders, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 8.4. Abort Button ΓòÉΓòÉΓòÉ Press the Abort button to abandon any changes you have made to the Split Weight and Balance Weight sliders, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 8.5.

Reset Button ΓòÉΓòÉΓòÉ Press the Reset button to reset the Split Weight and Balance Weight sliders to their defaults. ΓòÉΓòÉΓòÉ 9. Map Behavior Preferences ΓòÉΓòÉΓòÉ The Map Behavior dialog allows you to change the way in which the Map Window behaves. The following controls are provided: o Zoom Above Threshold o Zoom Threshold o Zoom Below Threshold o Page Scroll o Line Scroll o Zoom On Find o Autosave o Sector X Size o Sector Y Size o OK Button o Abort Button o Help Button o Reset Button ΓòÉΓòÉΓòÉ 9.1. Zoom Above Threshold ΓòÉΓòÉΓòÉ The Zoom Above Threshold slider is used to set the amount by which the scale of the Map Window changes when a Zoom is performed and the current scale is above the Zoom Threshold. This slider ranges from 1% to 25%. ΓòÉΓòÉΓòÉ 9.2. Zoom Threshold ΓòÉΓòÉΓòÉ The Zoom Threshold slider is used to set the scale at which the Zoom amount changes. This allows you to customize the zoom behavior to your liking. This slider ranges from 1% to 100%. ΓòÉΓòÉΓòÉ 9.3. Zoom Below Threshold ΓòÉΓòÉΓòÉ The Zoom Below Threshold slider is used to set the amount by which the scale of the Map Window changes when a Zoom is performed and the current scale is below the Zoom Threshold. This slider ranges from 1% to 25%. ΓòÉΓòÉΓòÉ 9.4. Page Scroll ΓòÉΓòÉΓòÉ The Page Scroll slider is used to set the percentage of the current view moved off the screen when a page scroll is performed on the Map Window. This slider ranges from 1% to 100%. ΓòÉΓòÉΓòÉ 9.5. Line Scroll ΓòÉΓòÉΓòÉ The Line Scroll slider is used to set the percentage of the current view moved off the screen when a line scroll is performed on the Map Window. This slider ranges from 1% to 100%. ΓòÉΓòÉΓòÉ 9.6. Zoom On Find ΓòÉΓòÉΓòÉ The Zoom On Find slider is used to set the scale to use for the Map Window when an object is "found". This is used by the Check map item. Zoom on Find can be disabled; if it is not disabled, it ranges from 1% to 200%. ΓòÉΓòÉΓòÉ 9.7. Autosave ΓòÉΓòÉΓòÉ The Autosave slider is used to set the amount of time which passes before the Map Window saves the current map to disk in case of disaster. The map will be saved as "AUTOSAVE.WAD" in DEPM's working directory. Autosave can be disabled; if it is not disabled, it ranges from 1 minute to 30 minutes between saves. ΓòÉΓòÉΓòÉ 9.8. Sector X Size ΓòÉΓòÉΓòÉ The Sector X Size field is used to set the X size of new sectors dropped onto the map from the Sector Template. The valid range for this field is 8 to 1024. ΓòÉΓòÉΓòÉ 9.9. Sector Y Size ΓòÉΓòÉΓòÉ The Sector Y Size field is used to set the Y size of new sectors dropped onto the map from the Sector Template. The valid range for this field is 8 to 1024. ΓòÉΓòÉΓòÉ 9.10. OK Button ΓòÉΓòÉΓòÉ Press the OK button to accept any changes you have made to the Map Behavior preferences, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 9.11. Abort Button ΓòÉΓòÉΓòÉ Press the Abort button to abandon any changes you have made to the Map Behavior preferences, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 9.12. Help Button ΓòÉΓòÉΓòÉ Press the Help button to display a help message about the Map Behavior dialog. ΓòÉΓòÉΓòÉ 9.13. Reset Button ΓòÉΓòÉΓòÉ Press the Reset button to reset the Map Behavior preferences to the default settings. ΓòÉΓòÉΓòÉ 10. Textures Preferences ΓòÉΓòÉΓòÉ The Textures dialog allows you to change the way DEPM deals with textures. The following controls are provided: o Red Compensation o Green Compensation o Blue Compensation o Render Textures on Selection o Render Textures into Bitmaps o Preload Textures from IWAD o OK Button o Abort Button o Help Button o Reset Button ΓòÉΓòÉΓòÉ 10.1. Red Compensation ΓòÉΓòÉΓòÉ When DEPM renders a texture, it attempts to translate the IWAD palette to the OS/2 system palette. DEPM allows you to adjust the way the palette is translated, so that you can experiment to determine the best translation for your system. The Red Compensation slider is used to set the amount of red added to the translated palette. This slider ranges from 0 to 99. ΓòÉΓòÉΓòÉ 10.2. Green Compensation ΓòÉΓòÉΓòÉ When DEPM renders a texture, it attempts to translate the IWAD palette to the OS/2 system palette. DEPM allows you to adjust the way the palette is translated, so that you can experiment to determine the best translation for your system. The Green Compensation slider is used to set the amount of green added to the translated palette. This slider ranges from 0 to 99. ΓòÉΓòÉΓòÉ 10.3. Blue Compensation ΓòÉΓòÉΓòÉ When DEPM renders a texture, it attempts to translate the IWAD palette to the OS/2 system palette. DEPM allows you to adjust the way the palette is translated, so that you can experiment to determine the best translation for your system. The Blue Compensation slider is used to set the amount of blue added to the translated palette. This slider ranges from 0 to 99. ΓòÉΓòÉΓòÉ 10.4. Render Textures on Selection ΓòÉΓòÉΓòÉ When a texture is selected in the SideDef Properties or Sector Properties dialogs, DEPM will not render the texture unless the selection is double-clicked. This is because the large size of the wall textures causes the rendering process to take a few seconds. If Render Textures on Selection is checked, DEPM will render textures as they are selected in the SideDef Properties and Sector Properties dialogs. Unless you are running a pentium with PCI or Local Bus video, I recommend you leave this option unchecked. When this checkbox is left unchecked, you can still cause textures to be rendered by double-clicking on them. ΓòÉΓòÉΓòÉ 10.5. Render Textures into Bitmaps ΓòÉΓòÉΓòÉ If Render Textures into Bitmaps is checked, DEPM will render textures into bitmaps as they are selected in the SideDef Properties and Sector Properties dialogs. This bitmap will be used for subsequent displays of that texture. ΓòÉΓòÉΓòÉ 10.6. Preload Textures from IWAD ΓòÉΓòÉΓòÉ If Preload Textures from IWAD is checked, DEPM will load the textures from the IWAD, into memory; this speeds up rendering operations, but requires a large amount of memory (typically 3 to 4 meg). If this option is left unchecked, DEPM will load the textures from the IWAD as it needs them; this will save a large amount of memory, but may slow down the texture rendering process slightly. Changes to this option will take effect the next time you load DEPM. ΓòÉΓòÉΓòÉ 10.7. OK Button ΓòÉΓòÉΓòÉ Press the OK button to accept any changes you have made to the Textures preferences, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 10.8. Abort Button ΓòÉΓòÉΓòÉ Press the Abort button to abandon any changes you have made to the Textures preferences, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 10.9. Help Button ΓòÉΓòÉΓòÉ Press the Help button to display a help message about the Textures dialog. ΓòÉΓòÉΓòÉ 10.10. Reset Button ΓòÉΓòÉΓòÉ Press the Reset button to reset the Textures preferences to the default settings. ΓòÉΓòÉΓòÉ 11. Thing Properties ΓòÉΓòÉΓòÉ The Thing Properties dialog allows you to change a thing's type, angle, and flags. The following controls are provided: o Category List Box o Type List Box o Angle Radio Buttons o Easy Checkbox o Medium Checkbox o Hard Checkbox o Deaf / Ambush Checkbox o Multi-Player Checkbox o OK Button o Abort Button o Help Button ΓòÉΓòÉΓòÉ 11.1. Category List Box ΓòÉΓòÉΓòÉ The Category list box allows you to change the category into which the thing falls. Things have been placed into categories to avoid having a list of all possible things in the game. Note that I categorize a barrel as being a weapon. When you select a category, the Type List Box is loaded with thing types which fall into that category. ΓòÉΓòÉΓòÉ 11.2. Type List Box ΓòÉΓòÉΓòÉ The Type list box allows you to select the thing's type. This list box will display only those thing types which fall into the category selected in the Category List Box. ΓòÉΓòÉΓòÉ 11.3. Angle Radio Buttons ΓòÉΓòÉΓòÉ The circle of radio buttons in the Angle group are used to change the direction in which the thing is facing when the map begins. Select one of these radio buttons to change the thing's angle. ΓòÉΓòÉΓòÉ 11.4. Easy Checkbox ΓòÉΓòÉΓòÉ When the Easy checkbox is checked, the thing will appear in Easy mode (skills 0 and 1). ΓòÉΓòÉΓòÉ 11.5. Medium Checkbox ΓòÉΓòÉΓòÉ When the Medium checkbox is checked, the thing will appear in Medium mode (skills 1 and 2). ΓòÉΓòÉΓòÉ 11.6. Hard Checkbox ΓòÉΓòÉΓòÉ When the Hard checkbox is checked, the thing will appear in Hard mode (skills 3 and 4). ΓòÉΓòÉΓòÉ 11.7. Deaf / Ambush Checkbox ΓòÉΓòÉΓòÉ When the Deaf / Ambush checkbox is checked, the thing (monster only) will not react until it sees the player. ΓòÉΓòÉΓòÉ 11.8. Multi-Player Checkbox ΓòÉΓòÉΓòÉ When the Multi-Player checkbox is checked, the thing will appear ONLY in multi-player games (co-op or deathmatch). ΓòÉΓòÉΓòÉ 11.9. OK Button ΓòÉΓòÉΓòÉ Press the OK button to accept any changes you have made to the thing's properties, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 11.10. Abort Button ΓòÉΓòÉΓòÉ Press the Abort button to abandon any changes you have made to the thing's properties, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 11.11. Help Button ΓòÉΓòÉΓòÉ Press the Help button to display a help message about the Thing Properties dialog. ΓòÉΓòÉΓòÉ 12. LineDef Properties ΓòÉΓòÉΓòÉ The LineDef Properties dialog allows you to change a linedef's type, flags, sector tag, and sidedefs. The following controls are provided: o Impassable Checkbox o Monsters Cannot Pass Checkbox o Two Sided Checkbox o Upper Texture Unpegged Checkbox o Lower Texture Unpegged Checkbox o Secret Checkbox o Sound Dampening Checkbox o Invisible on Map Checkbox o Mapped at Start Checkbox o Category List Box o Type List Box o Right Side Button o Left Side Button o Sector Tag o OK Button o Abort Button o Help Button ΓòÉΓòÉΓòÉ 12.1. Impassable Checkbox ΓòÉΓòÉΓòÉ When the Impassable checkbox is checked, the player will not be able to cross the linedef. ΓòÉΓòÉΓòÉ 12.2. Monsters Cannot Pass Checkbox ΓòÉΓòÉΓòÉ When the Monsters cannot pass checkbox is checked, monsters will not be able to cross the linedef. ΓòÉΓòÉΓòÉ 12.3. Two Sided Checkbox ΓòÉΓòÉΓòÉ When the Two sided checkbox is checked, shots and sound will travel across this linedef. This implies that the linedef has two sidedefs; if it doesn't, you will get the HOM effect and the game engine may slow to a crawl. Similarly, it is dangerous to create linedefs where there are two sidedefs, but this checkbox is not checked. ΓòÉΓòÉΓòÉ 12.4. Upper Texture Unpegged Checkbox ΓòÉΓòÉΓòÉ When the Upper texture unpegged checkbox is checked, the upper texture is "unpegged": when the ceiling of the sector adjacent to this linedef moves up, the upper texture will not move with it (used very rarely). ΓòÉΓòÉΓòÉ 12.5. Lower Texture Unpegged Checkbox ΓòÉΓòÉΓòÉ When the Lower texture unpegged checkbox is checked, the lower texture is "unpegged": when the ceiling of the sector adjacent to this linedef moves up, the lower and normal textures will not move with it (used mainly for door tracks). ΓòÉΓòÉΓòÉ 12.6. Secret Checkbox ΓòÉΓòÉΓòÉ When the Secret checkbox is checked, the linedef appears on the player's automap as a normal wall. ΓòÉΓòÉΓòÉ 12.7. Sound Dampening Checkbox ΓòÉΓòÉΓòÉ When the Sound dampening checkbox is checked, the linedef partially blocks sound. It takes two such linedefs to silence noise such that monsters will not react to it; this property is used only for two sided linedefs -- one sided linedefs are inherently soundproof. ΓòÉΓòÉΓòÉ 12.8. Invisible on Map Checkbox ΓòÉΓòÉΓòÉ When the Invisible on map checkbox is checked, the linedef will not appear on the player's automap. ΓòÉΓòÉΓòÉ 12.9. Mapped at Start Checkbox ΓòÉΓòÉΓòÉ When the Mapped at start checkbox is checked, the linedef will appear on the player's automap as soon as the map begins. ΓòÉΓòÉΓòÉ 12.10. Category List Box ΓòÉΓòÉΓòÉ The Category list box allows you to change the category into which the linedef falls. Linedefs have been placed into categories to avoid having a list of all possible types in the game. When you select a category, the Type List Box is loaded with linedef types which fall into that category. ΓòÉΓòÉΓòÉ 12.11. Type List Box ΓòÉΓòÉΓòÉ The Type list box allows you to select the linedef's type. This list box will display only those linedef types which fall into the category selected in the Category List Box. DEPM uses the following convention: TAR Description T indicates whether or not a sector tag is required; this will be "T" if a sector other than the one on the left side of the line is affected, or " " if the sector on the left side of the line will be affected. A indicates the activation type; this will be "W" if the linedef is activated when the player walks over it, "S" (switch) if the linedef is activated when the player pushes on it, or "G" (gun) if the linedef is activated when the player shoots it. R indicates whether the event can take place more than once; this will be "R" if the event is repeatable, or "1" if the event may take place once only (the single exception is "animated wall" which takes place all the time). Types which begin with an asterisk ('*') are available in DOOM2 only (I could be wrong). ΓòÉΓòÉΓòÉ 12.12. Right Side Button ΓòÉΓòÉΓòÉ The Right Side button label changes depending on whether or not a sidedef exists for the right side of this linedef: it will be "Edit" if one exists, "Add" if one does not exist. To add or edit the sidedef on the right side of this linedef, press the Right Side button: the SideDef Properties dialog will be displayed. ΓòÉΓòÉΓòÉ 12.13. Left Side Button ΓòÉΓòÉΓòÉ The Left Side button label changes depending on whether or not a sidedef exists for the left side of this linedef: it will be "Edit" if one exists, "Add" if one does not exist. To add or edit the sidedef on the left side of this linedef, press the Left Side button: the SideDef Properties dialog will be displayed. ΓòÉΓòÉΓòÉ 12.14. Sector Tag ΓòÉΓòÉΓòÉ The Sector Tag field allows you to enter the arbitrary sector tag to use for this linedef to identify the sector(s) it affects. This field accepts values from 0 (no tag) through 999. ΓòÉΓòÉΓòÉ 12.15. OK Button ΓòÉΓòÉΓòÉ Press the OK button to accept any changes you have made to the linedef's properties, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 12.16. Abort Button ΓòÉΓòÉΓòÉ Press the Abort button to abandon any changes you have made to the linedef's properties, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 12.17.

X Offset ΓòÉΓòÉΓòÉ The X Offset field allows you to enter an offset for the game engine to use when applying a texture to this sidedef. A positive offset "shifts" the texture to the LEFT; a negative offset "shifts" the texture to the RIGHT. This field accepts values from -128 through 128. ΓòÉΓòÉΓòÉ 13.2. Y Offset ΓòÉΓòÉΓòÉ The Y Offset field allows you to enter an offset for the game engine to use when applying a texture to this sidedef. A positive offset "shifts" the texture UP; a negative offset "shifts" the texture DOWN. This field accepts values from -128 through 128. ΓòÉΓòÉΓòÉ 13.3. Sector ΓòÉΓòÉΓòÉ The Sector field allows you to manually correct which sector this sidedef is a part of. If a group of sidedefs are assigned to the wrong sector, it is prudent to correct them as soon as possible to avoid future problems. This field accepts valid sector numbers only. ΓòÉΓòÉΓòÉ 13.4. Upper Texture Combo Box ΓòÉΓòÉΓòÉ The Upper Texture combo box allows you to change the texture applied to the area of this sidedef above the ceiling of the sector on the other side of the linedef. To view the texture you have selected, double-click on the selection.

Effects List Box ΓòÉΓòÉΓòÉ The Effects list box allows you to change the special effect which takes place in this sector. Light effects generally alternate between the light level of the sector and the light level of a neighbouring sector. ΓòÉΓòÉΓòÉ 16.6. Light Level ΓòÉΓòÉΓòÉ The Light Level field allows you to change the brightness of the sector; this can range from 0 to 255. ΓòÉΓòÉΓòÉ 16.7. Sector Tag ΓòÉΓòÉΓòÉ The Sector Tag field allows you to enter the arbitrary sector tag to use for this sector(s) to identify the linedefs which affect it. This field accepts values from 0 (no tag) through 999. ΓòÉΓòÉΓòÉ 16.8. OK Button ΓòÉΓòÉΓòÉ Press the OK button to accept any changes you have made to the sector's properties, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 16.9. Abort Button ΓòÉΓòÉΓòÉ Press the Abort button to abandon any changes you have made to the sector's properties, and to dismiss the dialog. ΓòÉΓòÉΓòÉ 16.10. Help Button ΓòÉΓòÉΓòÉ Press the Help button to display a help message about the Sector Properties dialog. ΓòÉΓòÉΓòÉ 17. The Editor Window ΓòÉΓòÉΓòÉ The Editor Window appears whenever you are editing a map. This window is used to control the Map Window, and provides a number of tools and indicators. These controls, tools, and indicators include: o Map Identifier o Things Radio Button o LineDefs Radio Button o Sectors Radio Button o Zoom Spin Button o Grid Spin Button o Thing Template o Vertex Template o Sector Template o Rendering Icon o Node Builder Icon o Shredder Icon o Mouse X, Y ΓòÉΓòÉΓòÉ 17.1. Map Identifier ΓòÉΓòÉΓòÉ The map identifier appears in the upper left corner of the Editor Window, and displays the current episode and map shown in the Map Window. For DOOM, this label will read ExMy where x is the episode and y is the map. For DOOM2, this label will read MAPxx where xx is the map (in DOOM2, there is one episode only). ΓòÉΓòÉΓòÉ 17.2. Things Radio Button ΓòÉΓòÉΓòÉ Pressing the Things radio button puts DEPM into things mode; in this mode, the Map Window will display the things on the map. When a thing is identified, the thing's type will be displayed at the bottom of the Edit Window, along with its set flags. In things mode the Thing Template becomes active. ΓòÉΓòÉΓòÉ 17.3. LineDefs Radio Button ΓòÉΓòÉΓòÉ Pressing the LineDefs radio button puts DEPM into linedefs mode; in this mode, the Map Window will display the linedefs and vertexes on the map. When a linedef is identified, the following information is displayed: LineDef x (y) RU, RN, RL, LU, LN, and LL textures. X is the linedef's sequential number and y is the length (in map units) of the linedef. RN, RL, RU, LN, LL and LU indicate whether or not a texture is defined for Right Normal, Right Lower, Right Upper, Left Normal, Left Lower, and Left Upper sidedef slots; if the indicator appears, then that texture is defined. When a vertex is identified, the following information is displayed: Vertex x where x is the vertex's sequential number. In linedefs mode the Vertex Template becomes active. ΓòÉΓòÉΓòÉ 17.4. Sectors Radio Button ΓòÉΓòÉΓòÉ Pressing the Sectors radio button puts DEPM into sectors mode; in this mode, the Map Window will display the sectors on the map. When a sector is identified, the following information is displayed: Sector x C: Ceiling Texture (height). F: Floor Texture (height) L: Light Level where x is the sector's sequential number. In sectors mode the Sector Template becomes active, unless the node builder is running. ΓòÉΓòÉΓòÉ 17.5. Zoom Spin Button ΓòÉΓòÉΓòÉ The zoom spin button is used to change the scale of the map displayed in the Map Window. Press the up arrow to increase the magnification. Press the down arrow to decrease the magnification. Alternately, the 1 through 0 keys will set the zoom amount to a preset scale (10, 20, 30, 40, 50, 60, 70, 80, 90, 100). ΓòÉΓòÉΓòÉ 17.6. Grid Spin Button ΓòÉΓòÉΓòÉ The grid spin button is used to change the display and snap of the grid displayed in the Map Window. Press the up arrow to increase the spacing between grid lines (sparser grid). Press the down arrow to decrease the spacing between the grid lines (denser grid). The available grid densities are none, 8, 16, 32, 64, 128, 256, 512 and 1024. ΓòÉΓòÉΓòÉ 17.7. Thing Template ΓòÉΓòÉΓòÉ The Thing template is used to create new things on the map in things mode: To create a new thing from the Thing template, place the mouse pointer on the template and hold down the right mouse button to drag the new thing to the desired location on the map: ΓòÉΓòÉΓòÉ 17.8. Vertex Template ΓòÉΓòÉΓòÉ The Vertex template is used to add new vertexes to linedefs on the map in linedefs mode: To create a new vertex from the Vertex template, place the mouse pointer on the template and hold down the right mouse button to drag the new vertex to the desired linedef location on the map: ΓòÉΓòÉΓòÉ 17.9. Sector Template ΓòÉΓòÉΓòÉ The Sector template is used to add new sectors to the map in sectors mode: To create a new sector from the Sector template, place the mouse pointer on the template and hold down the right mouse button to drag the new sector to the desired location on the map: ΓòÉΓòÉΓòÉ 17.10. Rendering Icon ΓòÉΓòÉΓòÉ When you start DEPM (or change the Textures Preferences), it will begin to render the textures into bitmaps for quicker display. While this is happening, the Rendering Icon will be displayed: While DEPM is rendering textures, you can continue to use the editor as usual. Selected textures will be rendered more slowly if they have not been converted to bitmaps yet. Once the texture has been converted, it will be rendered almost instantly. The speed of this process depends heavily on your CPU; on a 486/DX50 it takes about 15 minutes for DOOM, and about 20 minutes for DOOM2. It also depends on how much work you are doing while it is running; for example, running the node builder will slow it down considerably. It is a good idea to leave DEPM running if you intend to use it (minimize it instead of closing it when testing your maps). This will avoid making DEPM render all the textures again. ΓòÉΓòÉΓòÉ 17.11. Node Builder Icon ΓòÉΓòÉΓòÉ When the node builder is running, the Node Builder Icon will be displayed: While the node builder is active, you cannot enter linedefs mode; nor can you add or delete sectors. ΓòÉΓòÉΓòÉ 17.12. Shredder Icon ΓòÉΓòÉΓòÉ The Shredder icon is used to delete things, vertexes, linedefs, and sectors. It operates just like the OS/2 workplace shell shredder. To delete an object from the map, place the mouse pointer on the object and hold down the right mouse button to drag the object to the shredder icon. ΓòÉΓòÉΓòÉ 17.13. Mouse X, Y ΓòÉΓòÉΓòÉ The Editor Window reports the position of the mouse on the Map Window by placing the map coordinates of the mouse into the "X : " and "Y : " fields. ΓòÉΓòÉΓòÉ 18. The Map Window ΓòÉΓòÉΓòÉ The Map Window appears whenever you are editing a map. This window is used to display and edit the map using direct manipulation. Two scroll bars are provided: o Vertical Scrollbar o Horizontal Scrollbar Drag and Drop allows you to perform different operations depending on the edit mode: o Things Mode o LineDefs Mode o Sectors Mode ΓòÉΓòÉΓòÉ 18.1. Vertical Scrollbar ΓòÉΓòÉΓòÉ The Vertical scrollbar allows you to reposition the map vertically in the Map Window by using line scrolls, page scrolls, and by dragging the thumb tab. ΓòÉΓòÉΓòÉ 18.2. Horizontal Scrollbar ΓòÉΓòÉΓòÉ The Horizontal scrollbar allows you to reposition the map horizontally in the Map Window by using line scrolls, page scrolls, and by dragging the thumb tab. ΓòÉΓòÉΓòÉ 18.3. Things Mode ΓòÉΓòÉΓòÉ The following direct operations are supported in things mode: o Adding a Thing o Moving a Thing o Deleting a Thing o Cloning a Thing o Editing a Thing ΓòÉΓòÉΓòÉ 18.3.1. Adding a Thing ΓòÉΓòÉΓòÉ To add a new thing to a map, position the mouse pointer on the Thing Template and hold down the right mouse button to drag the new thing to the desired map location. The new thing created will be a duplicate of the last thing saved. ΓòÉΓòÉΓòÉ 18.3.2. Moving a Thing ΓòÉΓòÉΓòÉ To move a thing on a map, position the mouse pointer on the thing you wish to move, and hold down the right mouse button to drag the thing to the desired map location. ΓòÉΓòÉΓòÉ 18.3.3. Deleting a Thing ΓòÉΓòÉΓòÉ To delete a thing from a map, position the mouse pointer on the thing you wish to delete, and hold down the right mouse button to drag the thing to the Shredder Icon. Alternately, position the mouse pointer on the thing you wish to delete, click the right mouse button, and select the Delete item on the Delete Menu. Alternately, position the mouse pointer on the thing you wish to delete, and press the Delete key. ΓòÉΓòÉΓòÉ 18.3.4. Cloning a Thing ΓòÉΓòÉΓòÉ To clone a thing on a map, position the mouse pointer on the thing you wish to clone, and hold down the Ctrl key and the right mouse button to drag the thing's clone to the desired map location. ΓòÉΓòÉΓòÉ 18.3.5. Editing a Thing ΓòÉΓòÉΓòÉ To edit a thing on a map, position the mouse pointer on the thing you wish to edit, and click the left mouse button. The Thing Properties dialog will be displayed. Use the OK Button to save the changed thing. ΓòÉΓòÉΓòÉ 18.4. LineDefs Mode ΓòÉΓòÉΓòÉ The following direct operations are supported in linedefs mode: o Adding a Vertex o Moving a Vertex o Deleting a Vertex o Cloning a Vertex o Merging Vertexes o Drawing a LineDef o Deleting a LineDef o Editing a LineDef o Cloning a LineDef o Flipping a LineDef o Swapping SideDefs o Texture Palette ΓòÉΓòÉΓòÉ 18.4.1. Adding a Vertex ΓòÉΓòÉΓòÉ To add a new vertex to a linedef on a map, position the mouse pointer on the Vertex Template and hold down the right mouse button to drag the new vertex to the desired map location on the linedef you wish to split. The linedef will be split by the new vertex; the two new linedefs will be duplicates of the one which was split. ΓòÉΓòÉΓòÉ 18.4.2. Moving a Vertex ΓòÉΓòÉΓòÉ To move a vertex on a map, position the mouse pointer on the vertex you wish to move, and hold down the right mouse button to drag the vertex to the desired map location. Be careful not to drop the vertex on a linedef because the linedef will be split (be extra cautious when using the grid). ΓòÉΓòÉΓòÉ 18.4.3. Deleting a Vertex ΓòÉΓòÉΓòÉ To delete a vertex from a map, position the mouse pointer on the vertex you wish to delete, and hold down the right mouse button to drag the vertex to the Shredder Icon. This will also delete any linedefs which use the vertex as an endpoint, so be careful. Alternately, position the mouse pointer on the vertex you wish to delete, click the right mouse button, and select the Delete item on the Delete Menu. Alternately, position the mouse pointer on the vertex you wish to delete, and press the Delete key. ΓòÉΓòÉΓòÉ 18.4.4. Cloning a Vertex ΓòÉΓòÉΓòÉ To clone a vertex to a linedef on a map, position the mouse pointer on the vertex you wish to clone, and hold down the Ctrl key and the right mouse button to drag the cloned vertex to the desired map location on the linedef you wish to split. Note that this is the same as adding a vertex from the Vertex Template. The linedef will be split by the new vertex; the two new linedefs will be duplicates of the one split. ΓòÉΓòÉΓòÉ 18.4.5. Merging Vertexes ΓòÉΓòÉΓòÉ To merge two vertexes on a map, position the mouse pointer on the vertex you wish to remove, and hold down the right mouse button to drag the new vertex to the desired vertex you wish to merge it into. Any linedefs connected to the removed vertex will become connected to the vertex it was merged into, so be careful. Any linedefs which existed between the two vertexes will be deleted. This is a good way to remove linedefs: just merge the vertexes at either end of it. This allows you to keep sectors intact. ΓòÉΓòÉΓòÉ 18.4.6. Drawing a LineDef ΓòÉΓòÉΓòÉ To draw a new linedef on a map, position the mouse pointer on the vertex you wish to be the from vertex, and click the left mouse button. The mouse pointer will become a drawing tool: Next, position the mouse pointer on the vertex you wish to be the to vertex, and click the left mouse button. The linedef will be drawn. If the linedef bisects a sector, the sector will be split; DEPM will start with the left sidedef of the new linedef, and will travel clockwise along the outside wall to reassign the sidedefs to the new sector. The sector created on the left will be a copy of the sector on the right. Sectors and obstacles within the new left sector will NOT be reassigned, and must be assigned manually. ΓòÉΓòÉΓòÉ 18.4.7. Deleting a LineDef ΓòÉΓòÉΓòÉ To delete a linedef from a map, position the mouse pointer on the linedef you wish to delete, and hold down the right mouse button to drag the vertex to the Shredder Icon. Alternately, position the mouse pointer on the linedef you wish to delete, click the right mouse button, and select the Delete item on the LineDef Menu. Alternately, position the mouse pointer on the linedef you wish to delete, and press the Delete key. If the last linedef separating two sectors is deleted, the sectors will be merged; DEPM will start with the left sidedef of the deleted linedef, and will travel clockwise along the outside wall to reassign the sidedefs to the sector on the right. The left sector will then be deleted. Sectors and obstacles within the left sector will NOT be reassigned, and must be assigned manually. ΓòÉΓòÉΓòÉ 18.4.8. Editing a LineDef ΓòÉΓòÉΓòÉ To edit a linedef on a map, position the mouse pointer on the linedef you wish to edit, and click the left mouse button. The LineDef Properties dialog will be displayed. Use the OK Button to save the changed linedef. The LineDef Properties dialog allows you to edit the sidedefs as well. ΓòÉΓòÉΓòÉ 18.4.9. Cloning a LineDef ΓòÉΓòÉΓòÉ To clone a linedef on a map, position the mouse pointer on the linedef you wish to clone, hold down the Ctrl key and click the left mouse button. The mouse pointer will become an applicator: Next, position the mouse pointer on the linedef you wish to apply the original linedef's properties to, and click the left mouse button. The properties of the original linedef (and its sidedefs) will be copied to the target. You can then apply the properties to another linedef by continuing to use the left mouse button, or you can press the Esc key to discard the applicator (stop cloning). ΓòÉΓòÉΓòÉ 18.4.10. Flipping a LineDef ΓòÉΓòÉΓòÉ To flip a linedef's from and to vertexes, position the mouse pointer on the linedef you wish to flip, and click the right mouse button. The LineDef Menu will be displayed. Select the Flip item to flip the linedef. The sidedefs will be swapped as well. ΓòÉΓòÉΓòÉ 18.4.11. Swapping SideDefs ΓòÉΓòÉΓòÉ To swap the sidedefs for a linedef, position the mouse pointer on the linedef whose sidedefs you wish to swap, and click the right mouse button. The LineDef Menu will be displayed. Select the Swap item to swap the sidedefs. ΓòÉΓòÉΓòÉ 18.4.12. Texture Palette ΓòÉΓòÉΓòÉ Once the textures have been rendered, the Texture Palette becomes available. The Texture Palette can be invoked from the Map Window by pressing the F9 key, or by clicking both the left and right mouse buttons simultaneously. ΓòÉΓòÉΓòÉ 18.5. Sectors Mode ΓòÉΓòÉΓòÉ The following direct operations are supported in sectors mode: o Adding a Sector o Deleting a Sector o Editing a Sector o Cloning a Sector ΓòÉΓòÉΓòÉ 18.5.1. Adding a Sector ΓòÉΓòÉΓòÉ To add a new sector to a map, position the mouse pointer on the Sector Template and hold down the right mouse button to drag the new sector to the desired map location. The new sector created will be a duplicate of the last sector saved. If you are adding a sector inside another sector, the linedefs defining the sector will be made two sided. If you are adding a sector outside of all other sectors, try to drop the new sector close to an existing sector in one of the cardinal directions (up, down, left or right); DEPM searches the map for the closest sidedef by spiralling outward until it finds one (this can take a few seconds if the search is a long one). ΓòÉΓòÉΓòÉ 18.5.2. Deleting a Sector ΓòÉΓòÉΓòÉ To delete a sector from a map, position the mouse pointer on the sector you wish to delete, and hold down the right mouse button to drag the sector to the Shredder Icon. Alternately, position the mouse pointer on the sector you wish to delete, click the right mouse button, and select the Delete item on the Delete Menu. Alternately, position the mouse pointer on the sector you wish to delete, and press the Delete key. If you delete a sector from within a sector, the linedefs defining the deleted sector will be changed to define an obstacle. ΓòÉΓòÉΓòÉ 18.5.3. Editing a Sector ΓòÉΓòÉΓòÉ To edit a sector on a map, position the mouse pointer on the sector you wish to edit, and click the left mouse button. The Sector Properties dialog will be displayed. Use the OK Button to save the changed sector. ΓòÉΓòÉΓòÉ 18.5.4. Cloning a Sector ΓòÉΓòÉΓòÉ To clone a sector on a map, position the mouse pointer on the sector you wish to clone, hold down the Ctrl key and click the left mouse button. The mouse pointer will become an applicator: Next, position the mouse pointer on the sector you wish to apply the original sector's properties to, and click the left mouse button. The properties of the original sector (floor and ceiling textures, light level, effect and tag) will be copied to the target. You can then apply the properties to another sector by continuing to use the left mouse button, or you can press the Esc key to discard the applicator (stop cloning). ΓòÉΓòÉΓòÉ 19. Find Thing ΓòÉΓòÉΓòÉ The Find Thing dialog allows you to select a type of thing to search for, and to find the first occurrence of that thing on the map.

Vertex A point in two-dimensional space which defines the end-point of one or more two-dimensional lines. Linedef A two-dimensional line which connects exactly two (2) vertexes. Sidedef A plane into the third dimension along one side of a linedef. Sector A map area bounded by sidedefs. Sector Tag An arbitrary number used to assign linedef effects to sectors. Texture The game appearance of a floor, ceiling, or wall. Episode In DOOM, a grouping of nine (9) maps; in DOOM2 there is one episode only. Map A group of things, vertexes, linedefs, sidedefs and sectors which define a scenario for game play; also known as a "level". Extra A resource for sound, music, wall texturing, and so on. IWAD A large file containing all resources needed for basic play; distributed by id Software with the game. PWAD A smaller file which is used to "patch" the IWAD; can contain maps and/or extras. Node Builder A program which "compiles" a map into a form which the game engine uses while rendering the game "world". Compress a process by which duplicate sidedefs are removed from a PWAD to reduce its size. ΓòÉΓòÉΓòÉ 21.1. Things ΓòÉΓòÉΓòÉ A thing is an object (for example, a monster) that exists in the game world, but does not DEFINE the game world. Things do not have to be visible, and may not always appear. Examples of things are: monsters, teleport exits, weapons, ammo, decorations, player starting points, and bonus items. A thing has the following properties: Type What the thing is (teleport exit, monster, ammo, and so on). Angle The direction in which the object is facing when the map begins. This applies to monsters, player starts, and teleport exits. It is not important, for example, which way a shotgun is facing -- it will always look the same. Flags A number of on/off bits that determine the object's behavior and when it appears: Easy Thing appears in EASY mode (skill 0). Medium Thing appears in MEDIUM mode (skills 1 and 2). Hard Thing appears in HARD mode (skills 3 and 4). Deaf / Ambush Thing (monster only) does not react until it sees the player. If this bit is left off, the monster will react when it hears shots. Multi-Player Thing appears in multi-player (deathmatch or cooperative) mode ONLY. ΓòÉΓòÉΓòÉ 21.2. Vertexes ΓòÉΓòÉΓòÉ A vertex is a point in two dimensional space which defines the end-point of one or more two-dimensional linedefs. It has no attibutes other than its position on the map. ΓòÉΓòÉΓòÉ 21.3. LineDefs ΓòÉΓòÉΓòÉ A linedef is a two-dimensional line which connects exactly two (2) vertexes. Linedefs do not necessarily define walls (they CAN); they simply indicate a line along which the map makes a transition from one "area" to another. Linedefs travel from one vertex to another. This direction is very important because a linedef may have two sides: a right side and a left side. If you rotate the linedef so that it is pointing straight up (the from vertex is on the bottom), the right side is the right side of the line. Linedefs can be used to "trigger" events when the player crosses them, or pushes on them (switches, doors, lifts). Some linedefs trigger the sector on their left sides, some trigger a sector on neither side. A linedef which triggers an event in a sector other than the one on its left side must be defined with a sector tag which is used by the sector affected. For example, if linedef #231 causes sector #21 to raise, both must have the same sector tag (for example, "13"). More than one sector and more than one linedef can have the same sector tag. A linedef has the following properties: Type What the linedef does when activated. DEPM uses the following convention: TAR Description T indicates whether or not a sector tag is required; this will be "T" if a sector other than the one on the left side of the line is affected, or " " if the sector on the left side of the line will be affected. A indicates the activation type; this will be "W" if the linedef is activated when the player walks over it, "S" (switch) if the linedef is activated when the player pushes on it, or "G" (gun) if the linedef is activated when the player shoots it. R indicates whether the event can take place more than once; this will be "R" if the event is repeatable, or "1" if the event may take place once only (the single exception is "animated wall" which takes place all the time). Attributes A number of on/off bits that determine the linedef's properties: Impassable The player cannot cross this linedef. Monsters cannot pass Monsters cannot cross this linedef. Two Sided This linedef has two sides; monsters and players can move and shoot through this linedef. Upper texture unpegged When the ceiling of the sector adjacent to this linedef moves up, the upper texture will not move with it (used very rarely). Lower texture unpegged When the ceiling of the sector adjacent to this linedef moves up, the lower and normal textures will not move with it (used mainly for door tracks). Secret This linedef appears to be a normal wall on the automap (used mostly for secret doors). Sound dampening This linedef dampens sound. It takes two such linedefs to silence noise such that monsters will not react to it; this property is used only for two sided linedefs -- one sided linedefs are inherently soundproof. Invisible on map This linedef does not appear on the automap. Mapped at start This linedef appears on the automap at the start of the map. Sector Tag The arbitrary sector tag which is used by the sector(s) this linedef affects. Right Side The sidedef on the right side of the linedef. Left Side The sidedef on the left side of the linedef. ΓòÉΓòÉΓòÉ 21.4. Sidedefs ΓòÉΓòÉΓòÉ A sidedef can be thought of as a plane into the third dimension along one side of a linedef. It defines the appearance of its side of the linedef in the game "world". A sidedef has the following properties: X Offset The horizontal offset into the textures from the left. A positive offset "shifts" the texture to the LEFT; a negative offset "shifts" the texture to the RIGHT. Y Offset The vertical offset into the textures from the bottom. A positive offset "shifts" the texture UP; a negative offset "shifts" the texture DOWN. Sector The sector this sidedef is a part of. Normal Texture The texture rendered between the ceiling and the floor in the sector this sidedef is a part of. Lower Texture The texture rendered in the sector this sidedef is a part of, below the floor of the sidedef on the other side of the linedef. Upper Texture The texture rendered in the sector this sidedef is a part of, above the ceiling of the sidedef on the other side of the linedef. ΓòÉΓòÉΓòÉ 21.5. Sectors ΓòÉΓòÉΓòÉ A sector is an "area" on the map. It defines a region to which its properties apply. A sector is defined by the sidedefs which are parts of it. A sector has the following properties: Floor Height The height of the floor; this can range from -16384 to 16383. Floor Texture The texture rendered onto the floor of the sector. Note that floor textures are aligned on a 64-unit grid. Ceiling Height The height of the ceiling; this can range from -16384 to 16383, but must be greater than the floor height. Ceiling Texture The texture rendered onto the ceiling of the sector. Note that ceiling textures are aligned on a 64-unit grid. Light Level The brightness of the sector; this can range from 0 to 255. Sector Tag The arbitrary sector tag which is used by the linedef(s) which affect this sector. Effect A special effect which takes place in the sector. Light effects generally alternate between the light level of the sector and the light level of a neighbouring sector. ΓòÉΓòÉΓòÉ 21.6. Sector Tags ΓòÉΓòÉΓòÉ A sector tag is an arbitrary, usually unique number which is used to identify a link between sectors and the linedefs which affect them. More than one linedef can affect a sector; for example, one may start the floor moving, another may stop the effect (or, more than one may lower a lift). Likewise, more than one sector can be affected by a linedef; for example, a linedef may cause a number of pillars to lower into the floor. DEPM allows you to find the first free tag by using the "Locate" menu and selecting "Free Tag". ΓòÉΓòÉΓòÉ 21.7. Textures ΓòÉΓòÉΓòÉ A texture is the graphical appearance of a wall, floor or ceiling. Floor and ceiling textures are stored as simple 64 x 64 bit colour values, and the game engine aligns them on a 64 x 64 grid. Wall textures are composed of smaller "patches" of graphics information which are rendered at different points along the wall; some walls are composed of a single patch, some are composed of many. ΓòÉΓòÉΓòÉ 21.8. Episodes ΓòÉΓòÉΓòÉ In DOOM, an episode is a group of nine maps. There are three episodes. In DOOM2, there is one episode only. ΓòÉΓòÉΓòÉ 21.9. Maps ΓòÉΓòÉΓòÉ A map is a group of things, vertexes, linedefs, sidedefs and sectors which define a scenario for game play; it is also known as a "level". A map must contain at least two sectors, must have four player start things, must have at least four deathmatch start things, and must have some way to end the map. ΓòÉΓòÉΓòÉ 21.10. Extras ΓòÉΓòÉΓòÉ An extra is a resource stored in a PWAD to alter the game environment by changing sounds, music, wall patches, or sprites. DEPM does not allow the creation or editing of extras, but it will allow you to copy them from one PWAD to another, or to rename them (if you want to mess around with these, I recommend you get the unofficial DOOM specs). ΓòÉΓòÉΓòÉ 21.11. IWADs ΓòÉΓòÉΓòÉ The IWAD is a large file containing all resources needed for basic play; it is distributed by id Software with the game. For DOOM, this file is named DOOM.WAD; if you select this IWAD when DEPM starts up with a new profile, DEPM will run in DOOM mode. For DOOM2, this file is named DOOM2.WAD; if you select this IWAD when DEPM starts up with a new profile, DEPM will run in DOOM2 mode. ΓòÉΓòÉΓòÉ 21.12. PWADs ΓòÉΓòÉΓòÉ A PWAD is a smaller file which is used to "patch" the IWAD; it can contain maps and/or extras. DOOM PWADs will not work with DOOM2 and vice-versa; however, DEPM allows you to load either type of PWAD in either mode, and makes the necessary adjustments. DEPM does not change the contents of the PWAD, therefore changing a PWAD from one game to the other still requires you to modify the PWAD contents (textures, things, and extras). ΓòÉΓòÉΓòÉ 21.13. Node Builder ΓòÉΓòÉΓòÉ The Node Builder is a program which "compiles" a map into a form which the game engine uses while rendering the game "world". When you enter linedefs mode, DEPM clears the previously-built nodes from memory (this removes "additional" vertexes from the map -- they are not "linked" to any linedef and would be confusing if they appeared in the editor). This means that before the map can be saved, the node builder must be run again. When the map needs to be rebuilt, and it is safe to do so, DEPM starts up a separate thread to run the node builder. This allows you to continue working in things mode and sectors mode. An indicator appears to let you know that the node builder is running. The node builder partitions each sector into sub-sectors which are concave (that is, from any point within the sub-sector, you can see every point on every sidedef that defines it). This requires some sidedefs to be split; a binary tree is built which contains the sub-sectors and definitions of their positions in two-dimensional space. The node builder selects "partition lines" along which to split sectors into sub-sectors by weighing the number of splits needed against the tree's overall balance. You can change the weights assigned to avoiding splits and balancing the tree. ΓòÉΓòÉΓòÉ 21.14. Compress ΓòÉΓòÉΓòÉ Many linedefs may have sidedefs which are identical. It is possible to make these linedefs point to a single sidedef without affecting the way the game engine operates (in fact, it may improve performance since the PWAD is smaller). Compress is a process by which duplicates are removed to reduce size. If you select compress and load a PWAD, DEPM will search for linedefs which point to a single sidedef, and will decompress these. This allows you to edit as usual. If you select compress and save a PWAD, DEPM will search for linedefs which could point to a single sidedef, and will compress these. If you load a compressed PWAD without decompressing it, you must not enter linedefs mode because the node builder will build something that makes absolutely no sense to the game engine. If you don't know whether a PWAD is compressed, load it in with compression selected; if the level was not compressed, DEPM won't do anything to it. If you are going to use compression, I recommend you not compress while saving until your "final cut"; loading and saving is MUCH faster when compression is turned off. ΓòÉΓòÉΓòÉ 22.
