FLAG_CAN_PASS_THRU Uses
Type(s) Description
Monster & NPC, Spawn Point Monster

If no_pass (blocking passage) is set for an object, no one can pass the tile it is on (true for walls or closed doors). But if this flag is set, the monster can pass through all no_pass objects which have pass_thru set.

This is used for example for ghosts who move through doors.
