EyediallyLive Canvas Scripting Engine

Write JavaScript. See it move. Real-time 2D physics simulations at 60 FPS.

Frame Loop Execution

Your entry file runs every animation frame with time, dt, persistent state, and canvas size.

Return particles, lines, vectors, circles, arcs, bars, and HUD text — no direct canvas API needed.

Assign to state and it survives between frames. Editing code or clicking Restart clears it.

Split helpers into files with named imports. Modules compile once; pass dt and state as arguments.

Projectile, collisions, explosions, orbits, springs, boids, and energy demos you can paste in.

Persist multi-file projects in Supabase and resume across sessions.
