Performance issues? Try Turbowarp: https://turbowarp.org/1281748855 This light ray effect works by first recursively splitting squares into four parts (see mode 3) when it is touching the bat to create a sort of background mask, and then rendering it multiple times at different sizes with soft light costumes. I got this idea from a yt video by IGoByLotsOfNames where he uses a similar technique in Unity to create a nice effect for the sun rays in his 3D Minecraft clone. I would be interested in seeing this effect in 3D on Scratch, it would look really cool, but the implementation to generate the quadtree would have to be changed. No credit for my implementation is required, but appreciated!
