Monster shooting

[n(o)(o)b]

Im trying to make a map using the "doom builder". I made some stuff, then went to test it, and the barrens are shooting through the walls, but regular bullets (like shotguns or pistols)arn't shooting through. So i was wondering, how do you get a monster to not shoot through a wall?
Usually all i have on al wall is "impassible" and "block-monster".
-thanks

Set the line flags to "Block Everything" and whatever else you want.

If your wall was made correctly, or if the Nodes are comiled correctly, you shouldnt be ablt to shoot through a REAL wall (not just a linedef that has the impassible tag on it).
