How to make walls that block light cones in 2D?
Hi everyone! I'm working on a top-down 2D stealth game. As pictured below, I'm trying to have enemies display a cone of light representing their vision area. The cone is simply a 2D sprite with a layer that puts it under everything except the background.
However, as you can see in the picture, the cone will go through objects. This isn't a problem to gameplay, since I can run a raycast to check that the sight's not blocked before enemies "see" the player, but it is a problem visually.
How can I fix this? At a basic level, I could run raycasts along the sides of the cone to detect the wall, and resize the cone, but that'd run into problems also, since not all parts of the cone will necessarily be blocked.
