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]);

}

...但输出为'undefined'。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]);
}

如果要删除所有子网格物体的最佳解决方案

namespace App\Http\Controllers;

use App\User;
use App\Repositories\UserRepository;
use App\Http\Controllers\Controller;

class UserController extends Controller
{
    /**
     * The user repository implementation.
     *
     * @var UserRepository
     */
    protected $users;

    /**
     * Create a new controller instance.
     *
     * @param  UserRepository  $users
     * @return void
     */
    public function __construct(UserRepository $users)
    {
        $this->users = $users;
    }

    /**
     * Show the profile for the given user.
     *
     * @param  int  $id
     * @return Response
     */
    public function show($id)
    {
        $user = $this->users->find($id);

        return view('user.profile', ['user' => $user]);
    }
}
