请教，在 Carame 上是如何实现序列帧动画？

使用threejs 在开发者工具可以显示 真机调试连canvas都不加载 体验版本的mtl加载失败 真机调试直接走不下去 上传体验版本之后看到的是没加载出材质 因为没有network查看也不知道具体原因 [图片]这个是开发者工具的效果 使用的资源在这https://github.com/yannliao/threejs-example-for-miniprogram 我是直接改了他的obj/loadObj.js 求助各位大神 import getDDSLoader from '../../jsm/loaders/DDSLoader.js'; import getMTLLoader from '../../jsm/loaders/MTLLoader.js'; import getOBJLoader from '../../jsm/loaders/OBJLoader.js'; import {OrbitControls} from '../../jsm/controls/OrbitControls'; export default function (canvas, THREE) { let {DDSLoader} = getDDSLoader(THREE); let {MTLLoader} = getMTLLoader(THREE); let OBJLoader = getOBJLoader(THREE); let window = THREE.global; let camera, scene, renderer, controls; let object; init(); animate(); function init() { //renderer { renderer = new THREE.WebGLRenderer({canvas}); renderer.setPixelRatio(window.devicePixelRatio); renderer.setSize(window.innerWidth, window.innerHeight); renderer.setClearColor('#FFFFFF', 1); } //camera { camera = new THREE.PerspectiveCamera(45, canvas.clientWidth / canvas.clientHeight, 1, 2000); camera.position.set(800, 0, 800); } //controls { controls = new OrbitControls(camera, canvas); controls.target.set(0, 0, 0); controls.update(); } // scene & light { scene = new THREE.Scene(); const ambientLight = new THREE.AmbientLight(0xffffff, 0.8); scene.add(ambientLight); //模型底部的光线照射，参数和环境光线同理 const DirectionalLight = new THREE.DirectionalLight(0xffffff, 0.25); //模型顶部的光线照射，参数和环境光线同理 const DirectionalLightOther = new THREE.DirectionalLight(0xffffff, 0.1); //设置光线从哪里照射 DirectionalLight.position.set(-2, -5, -3); DirectionalLightOther.position.set(2, 5, 3); scene.add(DirectionalLight); scene.add(DirectionalLightOther); scene.add(camera); } // texture let textureLoader = new THREE.TextureLoader(); let texture = textureLoader.load('https://file.zmplay.top/static/img/%E8%83%8C%E6%99%AF6%401x.e85e7a1.png'); console.log(1); new MTLLoader().setPath("https://file.zmplay.top/").load("new.mtl", function (materials) { materials.preload(); console.log(2); let loader = new OBJLoader(); loader.setMaterials(materials).load('https://file.zmplay.top/new.obj', function (obj) { object = obj; console.log(3); object.traverse(function (child) { if (child.name == "圆柱") { //给罐身贴图 child.material.forEach(childMaterial => { if (childMaterial.name == '罐身图片') { childMaterial.map = texture; } }) } }); scene.add(object); }); }); } function animate() { canvas.requestAnimationFrame(animate); render(); } function render() { camera.lookAt(scene.position); controls.update(); renderer.render(scene, camera); } }
