@richard So I’m trying to make a game where you’re in a 3d world made from (Raycasting). I’m using  
pxtt-Lantern, but the lantern breaks and does not do what I want it to. I just want it to do some fog effect around the player, making visibility harder, and not being able to see across a simple area that I choose, is there any way I could do that???

i think you would have to manually do it. like add a sprite around you and make it so it moves with you or something.
