very slowly and deliberately adding messaging and signals to objects using SDL's event queue. Basically tiles can send custom events with their unique id and a pointer to their animation class that gets caught by an event loop in the tilemap, which adds and removes them from a table. I just have to iterate that table and update all animations at once. Should be fine.
For some reason the tilemap is rendering random tiles though.
Should be fine.
Welp, that was a waste of time. Animation does work (again) and I do have signaling and messaging it just turns out I don't actually *need* it to make animation work. My cool new idea was functionally no different than what I was already doing, just in a different order. So ... later.
I found the old raycaster code I thought I lost so maybe I can finish that "article" on raycasting I started earlier this year but abandoned because I couldn't actually get the code to work.
