Spawning AI
AI Spawning: Make a brush, apply the Trigger texture to the entire brush. With the brush selected Right Click the 2d Grid > Trigger > Multiple. With the trigger still selected press "N", now check the box marked "Trigger_Spawn".
Now all you need is an actor (note this should work with all actors)
Right Click the 2d Grid> Actor> Enemy> Arab> AR> Ak47
(as you can see for the purpose of the tutorial I have used an Actor, who is an Enemy to the player, who has the outfit of a Arab, who is using an Assualt Rifle, and has the weapon AK47)

With the actor selected press "N" check the box: "SPAWNER" (note:: he will not spawn if the player can see him spawn)
You may now link the Trigger to the AI.
Select the Trigger, then select the AI Actor, press W. A visible line will connect them. The reason they are connected in this order is simple. The Trigger activates the Actor, not the other way around.
