Question

我有一个简单的应用程序，其中使用3D模型，我想从AssetBundle加载它们。我为每个模型类别（例如汽车，船只，树木…）创建了多个AssetBundles

我已经做完了，但是当我开始游戏并从AssetBundle加载所有模型时，FPS计数下降。游戏被卡住，直到加载了所有模型。

我尝试用开场视频隐藏它，但即使是视频也被卡住了。

很明显，我不能使用Threads系统，因为Unity API不是线程安全的。

我的问题是：是否有更好的方式（更有效率）来加载资产？

我的代码：

创建AssetBundle：

   [MenuItem("Assets/Create assetbundle")]
   static void CreateAssetBundle()
   {
    // this list of categories is read from a file, and I loop through it.
    // this is a bit older version, but the loop is the only difference...
    AssetBundleBuild carBuild = new AssetBundleBuild();
    AssetBundleBuild boatBuild = new AssetBundleBuild();
    string[] paths = AssetDatabase.GetAllAssetPaths();
    List<string> carAssets = new List<string>();
    List<string> boatAssets = new List<string>();
    foreach (var item in paths)
    {
        if (item.EndsWith(".ma") && item.StartsWith("Car")) // find all car models
        {
            carAssets.Add(item);
        }
        else if(item.EndsWith(".ma") && item.StartsWith("Boat")) // find all boat models
        {
            boatAssets.Add(item);
        }
    }
    carBuild.assetBundleName = "cars";
    carBuild.assetNames = carAssets.ToArray();
    boatBuild.assetBundleName = "boats";
    boatBuild.assetNames = boatAssets.ToArray();
    BuildPipeline.BuildAssetBundles("Assets/Test", new AssetBundleBuild[] { carBuild, boatBuild}, BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows);
  }

加载模型：

private IEnumerator LoadAssetsBundle()
{
    yield return null;
    List<string> categories = ReadFromAFile(); // the list is being loaded from a file
           yield return null;
    foreach(var category in categories)
    {
     using(WWW loader = WWW.LoadFromCacheOrDownload(@"file://D:\Test\"+category, 1))
     {
       yield return loader;
       AssetBundle bundle = loader.assetBundle;
       var temp = bundle.LoadAllAssetsAsync();
       yield return temp;
       foreach (var item in temp.allAssets)
       {
           Instantiate(item);
           yield return null;
       }
       bundle.Unload(false);
       yield return null;
     }
    }
}

编辑这里没有结果，也没有统一的答案。我想这是最好的选择……

在Unity 3D中加载AssetBundle会使FPS急剧下降
