Hi and thanks for sharing your shadowcasting implementation! I overall like its results better than other routines I've tried, but it has this funky feature that the visibility "leaks" from in between diagonal tiles. The previous routine I had in my current project also saw through diagonal corners, but it did it in a more natural way so that it had the more realistic outward widening sector. Your routine for some reason draws a one tile wide infinite "streak".

Basically I can get around this by just not having diagonal corners like this :-P But optimally, it would be great if the routine did not see through diagonal corners at all... I'm just wondering if you would have an easy solution to tweak it this way?

Attached a screenshot to illustrate. I also tweaked your routine a bit for my use so that you also see the tiles (the walls) that block your vision.

Thanks!
