This is the source code of my WASM4 jam entry from some time ago. It's a neat little software renderer, but the code is very unoptimized and has lots of game-jam sloppiness.
A flight sim game for the WASM-4 fantasy console.
The aerodynamic model is physically-based, but the plane parameters do not correspond to any particular real-world plane.
The renderer is very CPU-intensive; you will probably want to run this game on a decent desktop PC with Firefox or Chromium.
Gamepad 2 (🄴/🄳, 🅂/🄵): Pitch, Roll
Gamepad 1 (⭠ / ⭢, ⭡ / ⭣ ): Yaw, Throttle
Hold ⭣ at zero throttle to extend flaps and brake.
Trigger 1 (🅇) to toggle the altimeter between ground (HGT) and sea level (ALT).
Hold Trigger 2 (🅉 or 🄲) to trim the controls, Trigger 1 and Trigger 2 to reset the trim.
The controls are pretty hard to master; very small movements often suffice.
For the first mission, you only need to reach the runway; after that, you will have to land gracefully.
Shake off missiles by flying very close to the ground until they crash.
Good luck, pilot.
