0x1337c0de / Need help with debugging new xatrix mod
« on: April 03, 2017, 09:30:02 AM »
Hello friends,
currently I am working on adding xatrix multiplayer code to the openffa mod by skuller in order to get a nice new xatrix game library for ffa. I doubt there are any xatrix players out there at the moment, but hopefully this way I can motivate ffa-server admins to add this gametype to their ffa games.
Unfortunately I have no c programming language knowledge (I write PHP code most of the time).
Nevertheless I managed to sucessfully merge the 3.20 xatrix gamelib code to the openffa code so that it even compiles without errors - yay
. It was quite hard for me since skuller modified a lot code which deals with items and especially weapons - I had to readapt this changes onto the xatrix code aswell.
Xatrix items are displayed, can be picked up and the weapons seem to fire correctly. The only issue is with traps. Once I throw a trap and jump right into it, the server crashes with a memoryaccess error (no more details given).
Could someone of the more experienced Q2 mod developers help me with debugging? I have absolutely no idea how to debug a c library crashing issue. How can I get more informatin about the source of the error?
My current working state is available on github: https://github.com/Niehztog/openffa
Once I managed to fix this bug I plan to merge in more changes, first the 3.24 xatrix gamelibrary changes by knightmare and later even the q2plus/tastyspleen additions especially for ionripper and traps. This would make openffa a fully qualified alternative to the quake2plus implementation.
My motivation is to bring more attention to the mission packs. I think there is no reason to not have them in the baseq2 main gamelibrary code, since everybody has them, they add nice new variety to items, gameplay-style and weapons and they contain no new playing-modes which would justify excluding them to mod-subdirectories.

Its possible to play Quake 2 with Xatrix Mod in CTF Mode, even with Bots. The trick is using good old Gladiator Bot, which includes Xatrix, Rogue, CTF and even RA2 code, which can all be activated selectively using server cvars.
