Three.js FirstPersonControls相机旋转在GSAP补间/重新启动控件后跳回

// 引入必要的库
import * as THREE from 'three';
import { FirstPersonControls } from 'three/examples/jsm/controls/FirstPersonControls.js';
import gsap from 'gsap';

// 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 FirstPersonControls
const controls = new FirstPersonControls(camera, renderer.domElement);

// 保存相机状态的函数
function saveCameraState() {
    return {
        rotation: camera.rotation.clone(),
        position: camera.position.clone()
    };
}

// 恢复相机状态的函数
function restoreCameraState(state) {
    camera.rotation.copy(state.rotation);
    camera.position.copy(state.position);
}

// 示例：使用 GSAP 动画
const cameraState = saveCameraState();
gsap.to(camera.position, { x: 5, duration: 2 }).then(() => {
    restoreCameraState(cameraState);
});

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