Moon Rider


Surf the musical road among the moon, stars, and northern lights.

A side project built by two people in a few months to show off VR running inside a webpage. Built with HTML, JavaScript, and A-Frame. Not meant to be an official game nor commerical product. Moon Rider is meant to be an open source resource for the web developer community to learn from, and to push forward the open WebXR initiative.

Remixing and Forking

Make this game your own! Some easy ways to mess around:

  • To modify or add more color palettes, change src/constants/colors.js.
  • To change images, replace images in src/assets/img/ folder. For example, replace the moon at `src/assets/img/moon.png'.
  • To change models, replace models in src/assets/models/ folder. For example, replace the arrow blocks at src/assets/models/arrowblue.obj or arrowred.obj.
  • To change sounds, replace sounds in src/assets/sounds. For example, replace the hit sounds at src/assets/sounds/.
  • Change various values such as speed in src/state/index.js or BEAT_PRELOAD_TIME in src/components/beat-generator.js to mess with how fast you travel along the curve, or how much reaction time until the notes arrive to the player.

Other ways such as adding more modes are more involved, but with knowledge of A-Frame and JavaScript, is doable!
