javascript - 从 Object3D 中移除子对象

Question

如果我按以下方式创建对象:

var group = new THREE.Object3D();

for (var i = 0; i < 10; i++) {

    geometry = new THREE.BoxGeometry(1, 1, 1);
    material = new THREE.MeshNormalMaterial();
    mesh = new THREE.Mesh(geometry, material);

    group.add(mesh);

}

scene.add(group);

那么，如何从该组中删除这些对象？

我试过这样做...

for (var i = group.children.length - 1; i >= 0; i--) {

    scene.remove(group.children[i]);

}

...但它输出为“未定义”。我在这里做错了什么？

Answer 1

for (var i = group.children.length - 1; i >= 0; i--) {
    group.remove(group.children[i]);
}
