"This is a plugin for making it easier to manage collisions with the Phaser game engine and the Matter.js physics engine.
Matter is one of the cool physics engine choices you have in Phaser 3. Phaser has a thin wrapper over Matter's API, so you need to dig into Matter's native collision event system if you want to detect and respond to collisions. That system just gives you a dump of all the pairs of bodies that collided in a tick of the engine. This plugin wraps up that collision logic in a friendlier, more modular way."
