hey people, ive really got the hang of designing levels and everything but im having one problem, how do i make it that i dont go through wall, wen my model for example goes to the wall he doesnt go through it, ive tried to do what i can and i keep goin through every wall someone help

var move

function not_moving_in_walls
{
while(1)
{
MOVE.X = (key_cuu - key_cud)*2*time;
use c_move(my,move,nullvector,glide);
wait(1);
}
}

First , make shure the wall isnt set to passable. Then check if you're moving the entity with a skill and use ent_move or c_move , dont use something like my.x += ... and finaly , make shure your camera is attached to an entity. If its not its like a fly-thru mode.

PS.: If you dont know how to use c_move or ent_move , check in the manual.
