Phaser Matter Collision Plugin 碰撞插件 -- iFiero技术分享

collision-simple-demo

Phaser 自带的Arcade虽然易用，但复杂的物理碰撞明显就不够用了，于是Matter等物理引擎还是不得不学的，以下是Matter物理体碰撞的一个插件，它省去了我们判别两个物理体相撞后哪个是gameObjectA和gameObjectB，实在是好用又省心，特推荐如下：

引入插件：

const config = {
  // ...
  physics: {
    default: "matter"
  },
  // Install the scene plugin
  plugins: {
    scene: [
      {
        plugin: PhaserMatterCollisionPlugin, // The plugin class
        key: "matterCollision", // Where to store in Scene.Systems, e.g. scene.sys.matterCollision
        mapping: "matterCollision" // Where to store in the Scene, e.g. scene.matterCollision
      }
    ]
  }
};

const game = new Phaser.Game(config);

识别二个相撞体

const player = this.matter.add.sprite(0, 0, "player");
const trapDoor = this.matter.add.image(200, 0, "door");

this.matterCollision.addOnCollideStart({
  objectA: player,
  objectB: trapDoor,
  callback: function(eventData) {
    // This function will be invoked any time the player and trap door collide
    const { bodyA, bodyB, gameObjectA, gameObjectB, pair } = eventData;
    // bodyA & bodyB are the Matter bodies of the player and door respectively
    // gameObjectA & gameObjectB are the player and door respectively
    // pair is the raw Matter pair data
  },
  context: this // Context to apply to the callback function
});

传感器

const player = this.matter.add.sprite(0, 0, "player");
const sensor = this.matter.world.add.rectangle(100, 0, 50, 50, { isStatic: true, isSensor: true });

this.matterCollision.addOnCollideStart({
  objectA: player,
  objectB: sensor,
  callback: eventData => console.log("Player touched hidden sensor")
});
