How do I use bossaction?

[m3_mapper]

I've been getting familiar with UMAPINFO as of late, and I noticed the entry for bossaction.

I followed its instructions, and I haven't been able to get it to work. I can't say I've found any useful guides.

 

How do I use bossaction? What is the syntax I need to use?

Sample from my project:

MAP MAP03
{
   levelname = "The Refinery"
   skytexture =  "sky1"
   music = "D_MAP03"
   bossaction = ShotgunGuy, 31, 300
   bossaction = HellKnight, 31, 301
   bossaction = Archvile, 31, 302
}

I suspect people with more experience will tear this to bits.

The Boss Action special can only be used with enemies that call "A_BossDeath". Therefore, enemies whose deaths can trigger things are limited to:

 

• Barons of Hell

• Cyberdemons

• Spider Masterminds

• Mancubi

• Arachnotrons

 

It is possible to fiddle with DeHackEd and give more/every enemy type the "A_BossDeath" pointer to widen your possibilities, but that goes beyond *only* using UMAPINFO.

Here's dehacked from 2 enemy community project I have that adds all missing BossDeath actions for standard doom 2 roster:

Patch File for DeHackEd v3.0
# Created with WhackEd4 1.2.4 BETA
# Note: Use the pound sign ('#') to start comment lines.

Doom version = 21
Patch format = 6

FRAME 192 = BossDeath
FRAME 197 = BossDeath
FRAME 225 = BossDeath
FRAME 230 = BossDeath
FRAME 274 = BossDeath
FRAME 349 = BossDeath
FRAME 428 = BossDeath
FRAME 434 = BossDeath
FRAME 461 = BossDeath
FRAME 469 = BossDeath
FRAME 495 = BossDeath
FRAME 515 = BossDeath
FRAME 577 = BossDeath
FRAME 600 = BossDeath
FRAME 719 = BossDeath
FRAME 748 = BossDeath
FRAME 757 = BossDeath

192,197 - zombieman death/xdeath
225,230 - shotgunner death/xdeath
274 - archvile
349 - revenant
428,434 - chaingunner death/xdeath
461,469 - imp death/xdeath
495 - pinky and spectre
515 - cacodemon
577 - hell knight
600 - lost soul
719 - pain elemental
748/757 - wolfenstein guy death/xdeath

 

 

I imagine UMAPINFO spec does not explicitly mention A_BossDeath codepointer and only says "boss death action" to not lock ports into specifics for implementation.

Dehacked can Run on pretty much anything that UMAPINFO can, so that souldn't be a problem.
