Hi, all i am a new game programmer that's why i m asking for help for every problem....
i am using BSP Maps in my FPS game using GDK for my final year Project... BSP maps have auto collisions feature... but i am unable to add gravity in my game... i read many threads and used the mentioned codes in them but all in vain...
please anyone help me to add gravity...here is my complete code
#include "DarkGDK.h"
#include "SC_Collision.h"

waiting for best response Thank u all....
