- How To Make Doom .lmp Demo's.
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
- Last Change: 4/3/94
-
-
- First of all, what IS a .lmp Doom demo.?
-
- Answer: in Doom, it is possible to record a playing session. ie. you can save
- to a file exactly what you do during a chosen episode and level. This file can
- then be played back later so that you can sit back and watch exactly what you
- did. The file itself does NOT contain any graphics images. The demo file merely
- records which keys get pressed and also the various mouse movements. However,
- there are certain key actions that are NOT recorded. These include using the
- ESC key to bring up the main menu and any actions taken using that menu. Also,
- you may find that using the mouse is not _quite_ as smooth as when playing
- normally - this is probably due to the overhead of having to record the various
- mouse movements as you play.
-
-
- HOW TO RECORD A .lmp DEMO.:
-
- The general command for recording a .lmp demo is as follows:-
-
-
- doom -devparm -warp <ep> <lv> -skill <num> -record <file> [-respawn]
-
-
- Where:
-
- <ep> is 1 for the shareware version, or 1 to 3 for the full version,
-
- <lv> is 1 to 9 (level 9 is always the secret level, although the actual
- from which you get _to_ a secret level is never level 8),
-
- <num> is 1 to 4 for v1.1, or 1 to 5 for v1.2,
-
- <file> is the name of the file that the demo is to be saved to. NOTE: the
- '.lmp' suffix MUST NOT be included in the file name. If you _do_
- include it, Doom will not be able to find the file!
-
- The option '-respawn' may be included; this makes the bad guys regenerate
- each time they get killed and also makes them faster, more accurate with
- their weapons/fire balls, enables them to shoot more often, etc. Thus, running
- Doom on skill level 4 with the -respawn option gives a level of difficulty
- kinda half way between 4 and 5 (where 5 is Nightmare mode).
-
- If you start the game in Nightmare mode, the '-respawn' option isn't needed
- (has _anyone_ managed to get past the initial set of doors in E3L1 in
- Nightmare mode?! If so, I wanna see a .lmp of it!).
-
- Demo making examples...
-
- Example 1:
-
- Record a demo of the Cyberdemon (Episode 2 Level 8) on skill level 3, saving
- it to a file called 'mydemo1.lmp'...
-
- doom -devparm dem -warp 2 8 -skill 3 -record mydemo1
- .
- /|\
- |
- Note! NO SUFFIX!
-
- Example 2:
-
- Record a demo of The Unholy Cathedral (Ep 3, lev 5) on Ultraviolence with
- respawning to a file called 'e3l5resp.lmp'...
-
- doom -devparm dem -warp 3 5 -skill 4 -record e3l5resp -respawn
-
-
- Example 3:
-
- Record a demo of the secret level on Epiosode 1 (The Military Base) in
- Nightmare mode, to a file called 'e1l9ntmr.lmp'...
-
- doom -devparm dem -warp 2 9 -skill 5 -record e1l9ntmr
-
-
- PLAYING BACK THE DEMO:
-
- The general command to play back a demo file is:
-
- doom -playdemo <file name>
-
- Where <file name> is the name of the .lmp demo file, BUT WITHOUT THE SUFFIX!.
-
- If the '-respawn' option was used to make the demo, it must be used when
- playing back the demo (the option is NOT needed for Nightmare mode demo's
- though).
-
- Thus, for the three examples above, they would be played back with the
- following commands respectively:
-
- doom -playdemo mydemo1
-
- doom -playdemo e3l5resp -respawn
-
- doom -playdemo e1l9ntmr
-
- You can save the demo at anytime by pressing Q. The demo also terminates when
- you get to the end of the level. If you die, then press Q to save. F10 will
- quit without saving.
-
-
- USING THE DEVPARM PARAMETERS BUT NOT TO MAKE A DEMO.:
-
- You can use the various devparm parameters to start a game off from a
- particular episode and level _without_ making a .lmp recording. This is done
- by not including the '-devparm dem' option, ie.:
-
- doom -warp <ep> <lv> -skill <num> [-respawn]
-
- The various parameters are just the same as before.
-
-
- Other notes:
-
- Trying to use ANY of the cheats when making a .lmp demo., will HALT the demo! One
- thing to remember, therefore, is that since the demo is going to STOP at the end
- of the level, there is no need for you to 'conserve' ammo for the next level.
-
- However, the PAUSE key _does_ get recorded during demo making, so try and make
- sure you don't get interupted by anything during play.
-
- You cannot save your position during a demo recording session. Pity... :(
-
-
- Anyway, that's all I can think of at the moment. I reckon that just about covers
- it!
-
-
- Have fun! :)
