NPCs detect player behind walls

[MilesTeg]

If the enemies inside a room notice me they start firing at me. That´s all right, but at the same time the stormies on the other side of a closed door try to shoot me too. (they shoot against the wall). The same thing happens with Stormies on the another floor.

 

Maybe the walls are too thin, but I can´t change them because my map is nearly finished.

 

Any idea what brush could help? (caulked ones? clip brushes??)

Why are the Stormies in the other rooms even active? There's no need for them to spawn until the player actually enters that area.

 

So my advice is to make some trigger_once entities and connect them to the stormtroopers in the other rooms. Then just make them spawn whenever you get close to the door to the next area. That should improve your FPS as well.

They are active because the player should see them through a camera. Even if I would activate them later the player must not kill all of the enemies and has to return to first room later - so there´s the same problem again.
