Vex.js

Vector Element Xpansion

A lightweight 2D game engine for JavaScript. Vex gives you a fixed-timestep game loop, physics-driven sprites, groups with object pooling, a camera system with follow/flash/fade, frame-based animation, and a tween manager — all as plain ES modules with no build step required.

Install / Run the demo

Arrow keys move, Space jumps. test/PlayState.js is a minimal example showing gravity, platform collision, camera follow, a screen flash, and a fade-in on load.
