我这样写哪里出了问题？ 怎么没有监听到加载资源？ 求大佬指正

const assetsNode = scene.createElement(xrFrameSystem.XRAssets)
    const textures = list.filter(i => i.type === AssetType.VIDEOTEXTURE)

    shadowNode.addChild(assetsNode)
    // 动态创建添加纹理资源
    textures.forEach(i => {
      this.loadAssets(i)
    })
    assetsNode.event.add("progress", event => {
      console.log('进度：', event)
    })
    assetsNode.event.add("loaded", event => {
      console.log('资源加载完成', event)
    })
async loadAssets(item) {
    const scene = this.scene
    const videoItem = await scene.assets.loadAsset({
      type: item.type,
      assetId: item.assetId,
      src: item.src,
      options: { autoPlay: true, loop: true, abortAudio: false },
    })
    console.log('videoItem.value:', videoItem.value.texture)
    const mat = scene.createMaterial(
      scene.assets.getAsset('effect', 'simple'),
      {u_baseColorMap: videoItem.value.texture }
    );
    // 可以将其添加到资源系统中备用
    scene.assets.addAsset('material', 'mat2', mat);
  }
