[solved] Line of Sight - enemies have x-ray vision

じ☆ve冰风

Hello,


        I'm using Fomar0153's Line of Sight script.


        Currently I'm creating an area where the player has to sneak past patrolling enemies and use the environment to hide from them. However, I noticed that the enemies can actually see through walls. I would like the enemies to not see the player if there's a tile between them that cannot be passed.


        Does anyone know how to modify the script in such a way? I will post the script below - hope that is ok.

                Code:
