- All about Demos for DMapEdit
- ----------------------------
-
- Demo files for DMapEdit have the extention '.rec', which stands for
- recording. By default, DMapEdit will use 'demo.rec' if you don't give
- it a filename. To play a demo file, you use the '-play' switch:
-
- dmapedit -play <-- playback the demo.rec file
- dmapedit -play doors <-- playback the doors.rec file
-
- With a demo running, the word 'demo' will flash in the upper left-hand
- corner of the screen just under the toolbar. This is just there to
- remind you a demo is playing. During playback, all control functions
- (mouse and keyboard) are read from the demo file, instead of you the
- user. You can stop playback at any time by pressing 'ESC'.
-
- During playback, windows will most likely appear from time to time
- containing information for you to read. This is to explain what the
- 'demo' is doing. With demo mode, I wanted to try and make it so that I
- could show each and every user of DMapEdit how to use my editor, without
- actually having to be there to show you myself. If I was there teaching
- you how to use it, I would talk to you and tell you exactly what I'm
- doing as I do it. Since I'm not really there, though, these windows
- serve that purpose.
-
- I call these windows 'info boxes'. When an info box appears, DMapEdit
- will wait until you read it all. When you are done reading it, all you
- need to do is press any key on the keyboard to continue, except 'ESC',
- since this will stop playback.
-
- Playback will automatically end when the end of the demo file being
- played is reached, or when DMapEdit terminates. In the first case, an
- info box will appear informing you that the demo is at an end. You will
- once again have full control of DMapEdit at this point.

- Recording Demos
- ---------------
-
- In addition to simply being able to play demos, you can also record your
- own demos. This can be useful for many reasons:
-
- * Someone you are trying to explain something to can't make heads or
- tails of what you are saying, and you can't get together with him/her
- to actually show them. An example is worth 10,000 words. (Just a
- simple picture is only worth 1,000!) You can create a demo for them
- to explain it all.
-
- * You've found a bug in DMapEdit that you can reproduce at will, but
- can't seem to explain the bug to me very well. You can create a demo
- that demonstrates the error happening.
-
- * You can create a tutorial on DMapEdit usage, or on how to create a
- PWAD from start to finish, or whatever. Beats reading a big long file.
-
- As you can see, the common theme here is 'DEMOnstrating' your ideas in
- real time. Ok, so how do you do it?
-
- Basically, you follow the same format for playing a demo, except you use
- the '-record' switch:
-
- dmapedit -record <-- record the demo.rec file
- dmapedit -record doors <-- record the doors.rec file
-
- Please note however that this will erase whatever file already exists
- with that name, overwritting it with your new demo. If you want to
- append to an existing demo, see below.
-
- Once DMapEdit is up and running, all mouse and keyboard commands are
- automatically saved as you go along. The word 'recording' will also
- flash in the upper left-hand corner of the screen just below the toolbar
- to remind you that it is recording a demo.
-
- "So what about the info boxes?" you are probably asking. When you are
- ready to have an info box display, simply press the ` key (not the ' key!),
- which should be located just below the 'ESC' on most keyboards. This
- will pop up a big empty window for you to put your message in. It's not
- the world's greatest editor or anything, but it does support cursor
- movement, insert, delete, page up/down, home, end, and word-wrap. If
- you find what you want to say is more than will fit in the window, put
- it into 2 windows instead, one right after the other.
-
- When you are done typing in your message to the user, pressing 'ESC'
- will save the window and let you continue where you left off. A word of
- warning, however. Info boxes are really only meant to be displayed from
- the 'main editing loop', inside standard windows (not picklists), and I
- added it to the 3D previewer as well. Anywhere else you try to bring one
- up will probably not work.
-
- To stop the demo, just press 'ESC' in the main editing loop. If you are
- not in the main editing loop, 'ESC' will do whatever it normally does
- (cancel the action and/or return to the main editing loop).
-
- Ok, so that about covers everything, right? Well, there's a few more
- things you might be interested to know about..
-
- While you are playing a demo, you can at any point switch over to
- recording mode by pressing 'Alt-R'. This can be very handy to pick up
- where you left off on a demo you started but didn't finish for whatever
- reason (got sleepy, ran into a bug, power failure, etc.) This is in
- fact the reason I put it in. I got tired of having to start all over
- from scratch each time I ran into a bug, or didn't like the direction I
- took with what I was doing and wanted to rewrite it. Once you are in
- recording mode, however, there is no way to switch back to playback
- again or anything. Anything else that was in the demo beyond your
- 'take-over' point is history.
-
- If you happen to create any really good demos, feel free to send it to
- me. I'll add it to the library of demos I distribute with DMapEdit, as
- well as the official DMapEdit homepage. Demos can redefine the whole
- meaning of what a map editor tutorial should do!
