我正在尝试获得一个带有 OrbitControls 的简单 ThreeJs，用于平移和缩放。我能够获得旧版本 (128) 的工作示例，但我在使用较新的 r168 时遇到了问题。
在示例中，我尝试将 js 代码直接写入 html 页面，并使用 cdn 导入 Threejs 依赖项，而不是本地源。
<body>
<script type="importmap">
{
"imports": {
"three": "https://unpkg.com/[email protected]/build/three.module.js",
"three/examples/jsm/controls/OrbitControls": "https://unpkg.com/[email protected]/examples/jsm/controls/OrbitControls.js"
}
}
</script>
<script type="module">
import * as THREE from 'three';
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js';
// Scene setup
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
// Renderer setup
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
renderer.setClearColor(0x000000); // Set background color to black
document.body.appendChild(renderer.domElement);
// Create a cube
const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);
// Position the camera
camera.position.z = 5;
// OrbitControls setup
const controls = new OrbitControls(camera, renderer.domElement);
controls.enableDamping = true; // Enable smooth damping
controls.dampingFactor = 0.25; // Adjust the damping factor for smoothness
controls.enableZoom = true; // Enable zoom
controls.enablePan = true; // Enable panning
// Animation loop
function animate() {
requestAnimationFrame(animate);
controls.update(); // Required if damping is enabled
renderer.render(scene, camera);
}
animate();
// Adjust canvas on window resize
window.addEventListener('resize', () => {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
renderer.setSize(window.innerWidth, window.innerHeight);
});
</script>
</body>
代码似乎从一开始就出现错误，在
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js';对于可能发生的情况以及如何解决此问题有任何帮助吗？
也许：
