Class: Physics

Physics functionality plugin

Remarks​

Based on the Matter.js engine.

Implements​

  • Plugin

Constructors​

new Physics()​

new Physics(options?): Physics

Creates an instance of the physics engine.

Parameters​

• options?: PhysicsOptions

PhysicsOptions

Returns​

Physics

Remarks​

The constructor must be called early in the game's initialize() method because it adds properties to the M2Node class for physics functionality. These properties will not be available to nodes before the physics plugin is created.

Example​

async initialize() {
  await super.initialize();
  const game = this;
  const physics = new Physics({ showsPhysics: true })
  await game.registerPlugin(physics);
  ...
}
