back to the A.I idea do you think it's possible to apply your technique to a radar system and/or Enemy line of sight. and have the line of sight be cut of by a box or wall etc... using the advanced laser technique, and when you are in enemies line of sight, have it the now A.I attack. Since it triggers a Text event I assume so.
and have multiple proxy's each further out from enemies eye's.
But... I assume you could just add a simple collision detection to do the same job?
