A First Game: Swoop
Righto, we can draw things to the screen, we can grab input from the user, all that remains is to create a game. I'm going to replicate my shadertoy game "space racer":
In shadertoy there are no sprites, so everything there is drawn in a single full-screen squad (with some buffering for state). This limits what is possible and makes things like the AI and counting laps hard to do in a way that will run performantly. By using WebGL only for the rendering and using rust/wasm for the collisions/logic, we should be able to create a better game.
