Pathfinding.
Or Poor Mans Obstacle Avoidance.
Whats this?
Well, Poor Mans Obstacle Avoidance can be found in some of the AUMS. It basicly works like that:
You constantly check the front of the enemy by using c_trace.
If the trace hits a wall in a certain distance, you add some pan to the enemies angle.
Thats how it basicly works, check the AUMS for details.
Or get yourself into pathfinding, but thats much more difficult.

gee thank's, i'll check out
