PrBoom demo support
|
|
===================
|
|
|
|
PrBoom has lots of demo options compared to most Doom ports, so I decided to
|
|
write a brief document outlining the features. If you're thinking of
|
|
recording demos, you're strongly advised to read this.
|
|
|
|
To play demos, you of course use "prboom -playdemo demoname" (the .lmp is
|
|
optional). To the best of my knowledge, PrBoom should play all MBF and new
|
|
PrBoom demos perfectly. It also plays most Doom v1.9 demos (significantly more
|
|
than Boom or MBF); almost all demos recorded with ultimate doom or doom2.exe
|
|
version v1.9 should work (please let me know if you find ones that don't), but
|
|
there are still problems with doom95 and final doom though. It should play most
|
|
Boom v2.01 and v2.02 demos, although I don't know of that many to test with. It
|
|
will also try to play older Doom demos, LxDoom demos, and Boom v2.00 demos.
|
|
|
|
Recording demos is done with "prboom -record demoname". **IMPORTANT** PrBoom
|
|
will record to a number of demo formats, namely Doom v1.9, Boom v2.02, MBF,
|
|
and PrBoom - which format it records is determined by your current
|
|
compatibility level, see README.compat. The purpose of this feature is so
|
|
people like me that won't let DOS anywhere near their computers can record
|
|
demos compatible with other engines.
|
|
|
|
PrBoom supports the -recordfrom parameter, which starts recording a demo
|
|
from a given savegame. "-recordfrom demoname n" is a synonym for "-record
|
|
demoname -loadgame n", which records a demo from savegame number n.
|
|
|
|
People doing speedrun demos may be interested in the comp_moveblock option,
|
|
see README.compat.
|
|
|
|
PrBoom supports loading and saving games during demo recording and playback
|
|
(but only for new PrBoom demos, not for older demo formats, obviously).
|
|
Don't worry, saves in demo playback are written with different names, they
|
|
don't overwrite your own saves. Saves when recording, do. You can load games
|
|
during recording, but they'd better be games saved during the same
|
|
recording, otherwise it won't play back.
|
|
|
|
PrBoom supports continuation of recorded demos. This is the scenario this
|
|
feature is designed for: say you're beta testing a level for someone, and
|
|
you want to send them a *complete* demo of how the level went (saves, deaths
|
|
and reloads and all). You start with "prboom test.wad -record test", play
|
|
for half an hour, save and exit. Next day, you go to play again, with
|
|
"prboom test.wad -record test" again. PrBoom will scan the existing
|
|
test.lmp, find the savegame command, and insert a loadgame command to reload
|
|
that game; it will reload the game and continue recording of the demo. This
|
|
is an experimental feature, but hopefully it works :-).
|
|
|
|
**IMPORTANT** The observant will have noticed from the above that PrBoom
|
|
won't overwrite existing demos anymore. If you want to record over a demo,
|
|
delete it first.
|
|
|
|
I think that's all for now.
