three.js如何实现简易3D机房？点击事件+呼吸灯效果

// 引入必要的Three.js组件
import * as THREE from 'three';
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader.js';
 
// 场景、相机、渲染器以及对象
let scene, camera, renderer, mesh, controls;
 
// 初始化场景、相机和渲染器
function initScene() {
    scene = new THREE.Scene();
    camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 0.1, 1000);
    renderer = new THREE.WebGLRenderer({ antialias: true });
    renderer.setClearColor(new THREE.Color(0x000000));
    renderer.setSize(window.innerWidth, window.innerHeight);
    document.body.appendChild(renderer.domElement);
    camera.position.set(0, 5, 10);
    camera.lookAt(new THREE.Vector3(0, 0, 0));
}
 
// 加载3D模型
function loadModel() {
    const loader = new GLTFLoader();
    loader.load('models/machine_room.glb', (gltf) => {
        mesh = gltf.scene;
        scene.add(mesh);
    });
}
 
// 添加灯光
function addLights() {
    const ambientLight = new THREE.AmbientLight(0xcccccc, 0.4);
    scene.add(ambientLight);
    const directionalLight = new THREE.DirectionalLight(0xffffff, 0.6);
    directionalLight.position.set(1, 1, 1);
    scene.add(directionalLight);
}
 
// 添加呼吸灯效果
function addLightsEffect() {
    const lights = mesh.getObjectByName('Lights');
    lights.traverse(function(child) {
        if (child.isMesh) {
            child.castShadow = true;
            setInterval(function() {
                child.material.emissive.setHex(Math.random() * 0xffffff);
            }, 1000);
        }
    });
}
 
// 监听鼠标点击事件
function addClickEvent() {
    renderer.domElement.addEventListener('click', function() {
        const raycaster = new THREE.Raycaster();
        const mouse = new THREE.Vector2();
        mouse.x = (event.clientX / window.innerWidth) * 2 - 1;
        mouse.y = - (event.clientY / window.innerHeight) * 2 + 1;
        raycaster.setFromCamera(mouse, camera);
        const intersects = raycaster.intersectObjects(scene.children);
        if (intersects.length > 0) {
            // 如果点击的是机房门，执行相关操作
            if (intersects[0].object.name === 'door') {
                // 这里可以添加门开关的逻辑处理
                console.log('门被点击了！');
            }
        }
    }, false);
}
 
// 初始化轨道控制器
function addOrbitControls() {
    controls = new OrbitControls(camera, renderer.domElement);
    controls.enableDamping = true;
