three.js ember js 中的动画

Question

我应该如何在 ember js 中为动画创建 three.js 的渲染循环。我现在的代码是

import Ember from 'ember';

export default Ember.Controller.extend({
  scene: new THREE.Scene(),
  camera: new THREE.PerspectiveCamera(75,
    window.innerWidth/window.innerHeight,1,500),
  renderer: new THREE.WebGLRenderer(),
  init: function() {
    this.renderer.setSize(window.innerWidth, window.innerHeight);
    document.body.appendChild(this.renderer.domElement);
    this.renderPreloader();
  },
  renderPreloader:function() {
    var geometry = new THREE.BoxGeometry( 1, 1, 1 );
    var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
    var cube = new THREE.Mesh(geometry,material);
    this.scene.add(cube);
    this.camera.position.set(2,2,2);
    this.camera.lookAt(cube.position);
    this.renderer.render(this.scene,this.camera);
    this.renderLoop();
  },
  renderLoop: function() {
    requestAnimationFrame(this.renderLoop);
    this.camera.position.x = this.camera.position.x+0.01;
    this.renderer.render(this.scene,this.camera);
  }
});

我收到的错误是 this 未在 requestAnimationFrame 处定义。解决这个问题的正确方法是什么？

Answer 1

要正确传递作用域，请执行：

requestAnimationFrame(this.renderLoop.bind(this));

或

requestAnimationFrame(() => {this.renderLoop()});
