Show HN: Build your own lunar lander autopilot
lunar.unnecessarymodification.com
Inspired by a previous post of a lunar lander game [1] and a subsequent autopilot for that same game [2], I made another lunar lander game where the user writes their own autopilot!
Its written in Svelte, rendering with HTML Canvas.
The options tab will let you set your initial conditions. The settings are encoded into the URL, and there's an option to include your autopilot code in the URL as well to save your state or share it with others.
