I'm sure this question has been asked before, but I've never seen an answer to it, so I'll ask it. Is it at all possible to flag an adjoin so that bullets can move through it, but the player cannot? I want to prevent the player from seeing the out-of-bounds area for an outdoor map and I dont want to have an invisible wall in my level.

Adjoin Flags you may want:
0x1F : passable bullets, impassible player & AI

0xF : passable bullets & player, impassible AI

0x17 : passable bullets &AI, impassible player
