[AS2] Enemy view

[Reaven99]

Hi,

Im working on a top down shooter but i cant get the line of sight working for the enemies.

Like if there is a wall between the player and the enemy the enemy cant see the player.

I think i almost tried every tutorial on the internet.. nothing worked out.

I need something for this but it also needs to be fast and working for small rooms.

I realy hope someone of you guys out there can help me.

EDIT:
I will pay the the one that comes up with a engine that actualy works!
So if you want some money help me making this engine!

Best regards,

Erik
