No LineofSight outside walls

You need to use LOS.

Although it looks like FOV sprite is blocked by walls, but in fact it isn't. So "overlapping FOV" will not work correctly if there is a wall between the player and the enemy.

The "FOV" object exists, even if it is not displayed. So, in your last screenshot, if an object was in the room where you don't see the "vision cone", it still would trigger the event, given the collision polygon is properly set up.

LOS would not, has it is out of sight, behind a wall.

The hit for using and forcing the own texture is minimal on the CPU since this is a webGL rendering thing that acts on the GPU.

The requirement for it to work is that your device supports webGL and does not fall back to Canvas2D.

Alright thanks both on clearing things up! I've added the LOS and it works great. Thank you both for the nice help!

I have one problem left with your example dop2000

When using multiple enemies with fov sprites then on places where one enemy has no visible fov (behind a wall for example) I can also not see other enemies which are at that place.

Don't know if you understand but I don't know how to describe it.

Hmm, I don't know.. You might need to place each enemy+FOV+shadowlight on a separate layer. Say, reserve 10 layers for that and spawn new enemy on an unoccupied layer.
