如何在three.js中向前移动3d对象的指向方向

// 引入three.js库
import * as THREE from 'three';

// 创建场景、相机和渲染器
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// 创建几何体和材质，并组合成网格
const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cube = new THREE.Mesh(geometry, material);

// 将网格添加到场景中
scene.add(cube);

// 设置相机的位置和方向
camera.position.z = 5;

// 渲染循环
function animate() {
  requestAnimationFrame(animate);

  // 更新网格的位置，使其沿着相机的方向向前移动
  cube.position.add(camera.getWorldDirection().multiplyScalar(0.1));

  // 渲染场景和相机
  renderer.render(scene, camera);
}
animate();
