AI-made platformer games

Platformers are action games about getting your character from point to point over uneven terrain and suspended platforms, jumping and climbing as you go. You run, time your jumps across gaps, avoid hazards like pits and reach the end of the level. Donkey Kong (1981) and Super Mario Bros. (1985) are the classic examples.

If you're making one, the movement code is the core of it, with gravity, a jump model (a fixed arc, or one you can steer mid-air) and collision tests against terrain and hazards. Levels are commonly built from a grid of tiles, and a scrolling level needs a camera that converts world coordinates to screen coordinates.

On the web, the Gamepad API reads controllers, and phones need on-screen buttons built with pointer events. Physics should use the elapsed time from requestAnimationFrame, or the game runs faster on high refresh-rate screens.
