三.js 冲突 GLTF

问：

我的游戏中有一个 GLTF 场景/关卡，我想阻止玩家进入墙内。 级别 ： https://sketchfab.com/3d-models/backrooms-level-0-3a43c43be8864c09aa0dff37c0b82001

和我的加载器代码：

loader.load(
// resource URL
"../../models/scene.gltf",
// called when the resource is loaded
function (gltf) {
  scene.add(gltf.scene);
  level = gltf.scene;
  gltf.animations; // Array<THREE.AnimationClip>
  gltf.scene; // THREE.Group
  gltf.scenes; // Array<THREE.Group>
  gltf.cameras; // Array<THREE.Camera>
  gltf.asset; // Object
},
// called while loading is progressing
function (xhr) {
  console.log((xhr.loaded / xhr.total) * 100 + "% loaded");
},
// called when loading has errors
function (error) {
  console.error(error);
}
return { level };

);
