与Threejs中的Click事件相比，Mouseover无法正常工作

// 初始化场景、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);

// 创建一个立方体
const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);

camera.position.z = 5;

// 设置Raycaster
const raycaster = new THREE.Raycaster();
const mouse = new THREE.Vector2();

// 添加鼠标移动事件监听器
window.addEventListener('mousemove', onMouseMove, false);

function onMouseMove(event) {
    // 将鼠标位置归一化为设备坐标
    mouse.x = (event.clientX / window.innerWidth) * 2 - 1;
    mouse.y = -(event.clientY / window.innerHeight) * 2 + 1;

    // 更新raycaster
    raycaster.setFromCamera(mouse, camera);

    // 检测与物体的交点
    const intersects = raycaster.intersectObject(cube);

    if (intersects.length > 0) {
        console.log('Mouse over the cube!');
    }
}

// 渲染循环
function animate() {
    requestAnimationFrame(animate);
    renderer.render(scene, camera);
}
animate();
