@britown fun fact: i do raycasted shadows/vision in midboss and at one point i emailed david brevik to ask how those were done in diablo 2. he then pointed out an optimization i'd never thought of: the fact you can cache the offsets for each ray to check ahead of time rather than doing a bresenham algorithm for each
meanwhile in midboss i basically just shoot a ray using bresenham from each and every tile within a certain visibility range to the player and if it gets blocked at any point that tile is obscured >_> works fine tbh
