xacer.js is a WebGL-based game engine.
This is an incomplete side project meant to learn the basics of how Entity-Component frameworks function.
A component-based engine, xacer.js is built to be flexible yet powerful.
Components should extend the Component class.
Prefabs (pre-built game objects) should extend the GameObject class.
