Hmm, I didn't know these, thanks! But I tried them and couldn't get them to work. My code is:
Code:
move_min_z = 1;
move_friction = 1;
c_move(player,HAREKET,nullvector,IGNORE_PASSABLE|GLIDE|USE_AABB);
Player can still run through big hills with that code smirk

The Life Game is disgustingly bad but the graphics and reality are extremely cool...
