Three.js + OrbitControls - Uncaught TypeError: Cannot read property 'addEventListener' of undefined

Question

我正在尝试在 THREE.js 中使用 OrbitControls。如果我从下面删除行 let cameraControl = new OrbitControls(camera) ，就不会有错误。但是现在，我有“未捕获的类型错误：无法读取未定义的属性 'addEventListener'”

我试图将 OrbitControls(camera) 更改为 THREE.OrbitControls(camera)，然后出现“未捕获的类型错误：THREE.OrbitControls 不是构造函数”。

我试图通过在 "module" 之外使用 <script src=...></script> 而不是 import {OrbitControls} from ...; 来导入 OrbitControls.js，但是它不起作用，我也尝试移动 let cameraControl = new OrbitControls(camera) 到其他线路，但也不起作用。

有什么解决办法吗？


<body>

<script type="module">
import * as THREE from 'https://threejsfundamentals.org/threejs/resources/threejs/r115/build/three.module.js';
import {OrbitControls} from 'https://threejsfundamentals.org/threejs/resources/threejs/r115/examples/jsm/controls/OrbitControls.js';


let scene, renderer, camera
let cube

function init() {

  scene = new THREE.Scene()
  renderer = new THREE.WebGLRenderer()
  renderer.setSize(window.innerWidth, window.innerHeight)
  document.body.appendChild(renderer.domElement)

  camera = new THREE.PerspectiveCamera(60, window.innerWidth / window.innerHeight, 0.1, 100)

  let cameraControl = new OrbitControls(camera)

  camera.position.set(10, 10, 10)
  camera.lookAt(scene.position)

  // cube
  cube = new THREE.Mesh(new THREE.BoxGeometry(1, 1, 1))
  scene.add(cube)

}

function render() {
  requestAnimationFrame(render)
  renderer.render(scene, camera)
}

init()
render()

</script>

Answer 1

let cameraControl = new OrbitControls(camera)

始终像这样创建控件：

let cameraControl = new OrbitControls(camera, renderer.domElement);

现在第二个参数是必须的。
