Well looking around you code of YaPB I find that :
NAMEFUNC.cpp
Code:
// RACC - AI development project for first-person shooter games derivated from Valve's Half-Life
// (http://www.racc-ai.com/)
//
// Rational Autonomous Cybernetic Commandos AI
//
// Since there is a known issue on Win32 platforms that prevents
// hook DLLs (such as our bot DLL) to be used in single player
// games (Training Room) because they don't export all the stuff
// they should, we may need to build our own array of exported
// symbols from the actual game DLL in order to use it as such
// if necessary.
//
Is this think is for Single Player?
Can you explain?
