Hexen BEHAVIOR cracked!
This is kind of embarassing ...

Subject: Hexen BEHAVIOR cracked!
Hello all.
I cracked much of the Hexen BEHAVIOR resource last night and wrote a partial
decompiler. (I haven't figured out all the pcodes yet.) I will make my
data available to any other editor author (I'm the author of WadAuthor)
willing to share what they know about the scripts. Here's hoping we all
have great editors ready to go when Hexen ships!

Does anyone have the source to BSP12x, I originally wrote it and
accidentally lost the code in the transit to Canada.

:) I have to disappoint anybody waiting for NWT 1.4 - right now there
is a lot of work for me - little time for NWT. BUT, there will be a
version of NWT, which will FULLY support Hexen. That's for sure.

When you play deathmatch, many doors are open and stairs activated. Somehow
I doubt all of the possible scripts are executed. How does the engine
determine which scripts get executed for deathmatch?

Whoops, I fowarded this to Oliver instead of sending to the group...

Exactly what I was thinking. Here's the little bit I've found out
about the BEHAVIOR resource (some of this is already known from the Hexen
FAQ):
ofs size
- --- ----
0 4 "ACS\0"
4 4 Offset of script directory (within the resource)
8 - Script data in 32-bit words. An 'opcode' of 1 appears to be
a script terminator
- - - String data. Just a list of null terminated strings. Most of
them are sounds, I think. There is also text that can be displayed
in a message ("Are you prepared to die?", etc.)
<script directory>
+0 4 Number of scripts
<script entries>
+0 4 Script ID number. This is probably how the
scripts are referenced from other resources. Most of them are
numbered 1,2,3... But then there are scripts with larger
numbers and with byte 2 set to 3 or 4. These may be large numbers or
the second byte might have a special meaning.
+4 4 Offset of script data
+8 4 Almost always zero. map 1 has a entry with 3, map 3 with a 2, and
map 4 with 1. Character-class flags? Deatmatch only?
<string directory>
- - 4 Number of strings
<string entries>
+0 4 Offset of string
That last table is a real pain. This means strings are referenced by
their table entry as opposed to their real offset. This makes hacking
the scripts much more difficult because it removes unique values from the
script data.
- -Update-
Scripts that have the value of 1000 added to them appear to run when the
level starts (or is played for the first time.) Check script 26 on
map2. It runs through the Korax thing. Note that script 10 also seems
to be a startup script, but can't be run again. These are supposedly
continuous scripts. My guess is that it controls the elevator that is
behind the Korax wall. I don't know what makes a script continuous yet...
Also, there are scripts with ID's outside of the range that can be played
with MWAGABAZA. All have scripts 255 and 254 (think -1 and -2). Map 1 has
253, map 2 1200, both map 3 and 4 have both 1100 and 1200. These are
probably deathmatch scripts to open all the doors. If someone knows the
script instructions, he can verify this.
If anyone finds additional info, please post it!
