FamilyKart · kart racing for my kids

A family-friendly kart-racing game as an Electron desktop app. A mini-engine with AI opponents, powerups, a chase camera and hand-built tracks. On top of Three.js, no game framework, vanilla JS for the game loop.

Hand-drawn sketch: Electron app with a chase cam above a racetrack loop, three karts (PLAYER + AI 1 + AI 2), powerups (BOOST, SHIELD, MISSILE), annotations '60 FPS · Three.js · vanilla JS' and 'AI rubberbanding'. — Whiteboard sketch · the game loop

What's in it

3D rendering on Three.js, custom scene graph and chase camera with smoothing
Kart physics with grip, drift, and jump
AI opponents with simple rubberbanding so the kids don't fall behind within three seconds
Powerups (boost, shield, missile) on pickup pads
HUD in a 2D canvas overlay on top of the 3D canvas
Custom tracks: not procedural, just hand-built to keep them short and kid-friendly
