How to know if an object is blocking my view of a light

[jorgeas80]

Yes, Penumbra has the "night vision" function, but just when I hit Left Ctrl (crouch). That could be a thing...

But I think I need something more generic. For example, if I'm behind a wall, and at the other side of the wall there's a light point, my lamp turns on, because I'm within the range of that light. Regardless the room I'm in it's totally dark of not. I Need to detect the wall between me and the light.

About the script area boundary, I'm not following you. I guess a script area is some part of the game where something happens (and raises a script). Can't see the relation between that fact and the lights.
