Finally uploaded this old fog of war test project from https://unitycoder.com/blog/2014/10/16/2d-fog-of-war-unity/ Its raycast + vertex color based effect. (not really optimized, as it linecasts each vertex right now..) Sources:https://github.com/unitycoder/FogOfWar Cleaning up the project and upgrading from 4.x:

Converted this AS3 2D raycast (by Lee Grey) to Unity javascript. (Image: raycast is coming from the middle, hits a wall..) Next: – Use grid array instead of reading pixels from image.. (done) – Try if this is faster compared to the old Raycast visibility […]

This is just a updated version of the: fake realtime raycast shadows (its not really shadows though..) Features in v2.0 Mesh is pre-build In update loop we just modify the existing vertices (no need to triangulate, create uv’s, etc in every frame) 50000 raycasts starts […]

Testing another way of doing realtime 2D shadows, by casting rays from the player position, then create “light” polygon to the area where we can see. More info later, need to test few things (using setpixels & shader? or using different shader for better light […]
