Server extension for Call Of Duty 1, 2 and 4

The Call of Duty extension libcod is adding new server-side functions to:

• Call Of Duty 2 1.2
• Call Of Duty 2 1.3
• Call Of Duty 4 1.7

Requirements:

dpkg --add-architecture i386
apt-get update
apt-get install gcc-multilib
apt-get install libmysqlclient-dev:i386
apt-get install g++-multilib

Precompiled shared libraries: http://killtube.org/downloads/libcod/

Starting the server:

LD_PRELOAD=libcod2_1_3_nomysql.so ./cod2_lnxded +set fs_game ...

Some enviroments need LD_LIBRARY_PATH also:

LD_LIBRARY_PATH=. LD_PRELOAD=libcod2_1_3_nomysql.so ./cod2_lnxded +set fs_game ...

Working with the source / Compiling:

./doit.sh tar
./doit.sh base # compiles object files needed by every .so
./doit.sh cod1_1_5 # compiles object files for CoD 1 1.5 and linking them against base to the actual bin/libcod1_1_5.so
./doit.sh cod2_1_2
./doit.sh cod2_1_3
./doit.sh cod4_1_7
./doit.sh wrapper

• http://killtube.org/showthread.php?1593-DOWNLOAD-CoD2-Portal-Mod
• Jump-Mod by IzNoGod

Little overview of added functions:

• MySQL
• setVelocity, getVelocity, addVelocity (needed for the mods: portal, surf)
• keyPressed-functions for left, right, forward, backward, leanleft, leanright, jump etc., (needed for: surf, doublejump made by IzNoGod)
• blazing fast astar-implementation (needed for: zombots)
• setAlive-function (needed for: zombots, so xmodels are damagable without damage-trigger... zombots in stockmaps)
• disableGlobalPlayerCollision()
