我用小游戏IDE引入three.js的json动画模型时，模型可以出来，动画怎么都出不来，请问有谁遇到过相同的问题吗？ ----------------------------------------------------------------------------------------------------------------- var loader = new THREE.JSONLoader(); loader.load('http://image.nardiaoyu.com/video/2018/2/11/neex7hh.js', function (geometry) { var material = new THREE.MeshPhongMaterial({ color: 0xffffff, specular: 0xffffff, shininess: 20, morphTargets: true, vertexColors: THREE.FaceColors, flatShading: true }); var mesh = new THREE.Mesh(geometry, material); var s = 0.35; mesh.scale.set(s, s, s); mesh.position.y = 15; mesh.rotation.y = -1; mesh.castShadow = true; mesh.receiveShadow = true; scene.add(mesh); console.log("mesh", mesh) mixer = new THREE.AnimationMixer(mesh); mixer.clipAction(geometry.animations[0]).setDuration(1).play(); console.log("mixer", mixer) mixers.push(mixer); console.log("mixers", mixers) for (var i = 0; i < mixers.length; i++) { console.log("mixers.length", i) } }); ----------------------------------------------------------------------------- animate() { requestAnimationFrame(this.animate.bind(this), canvas); this.render() //console.log("aaaaa") //stats.update(); } render() { var delta = clock.getDelta(); for (var i = 0; i < mixers.length; i++) { //console.log("mixers.length", mixers.length) mixers[i].update(delta); //console.log("t", t)* }
