I'm using line of sight to see if a projectile can hit it's target. aiming is with a crossheir like an arcade on rails shooter. Players will aim said crossheir with the right stick, and if they can see the point their crossheir is at. they can fire.
I wanted an invisible door that players could pass though, but not projectiles. If I made said door solid players would not be able to pass. So I added the door object to the line of sight as a custom obstacle.
yet for some reason the weapon can still see the point. it works fine with a solid obstacle. (the black wall.)
