在运行时动态加载FBX

Question

我正在尝试在运行时将已创建的FBX对象加载到场景中

我的代码在这里

void Start()
{
    string url = "http://everyday3d.com/unity3d/obj/monkey.obj";
    StartCoroutine(DownloadAssetBundle<GameObject>("monkey", url, 1));
}


public IEnumerator DownloadAssetBundle<T>(string asset, string url, int version) where T : UnityEngine.Object
{
    using(WWW www = WWW.LoadFromCacheOrDownload (url, version))
    {
        yield return www;
        if (www.error != null)
            throw new Exception(www.error);
        AssetBundle assetBundle = www.assetBundle;

        var Object = assetBundle.LoadAsset(asset, typeof(T));
        Instantiate(Object);
        assetBundle.Unload(false);
    }
}

我有错误

NullReferenceException: Object reference not set to an instance of an object
Loader+<DownloadAssetBundle>c__Iterator0`1[UnityEngine.GameObject].MoveNext () (at Assets/Script/Loader.cs:24)

我发现它是什么，因为www.assetBundle == null 解决这个问题的任何想法都有？阅读论坛，我意识到我的代码如正常。

因为您的代码显然是为了下载资产包而不是单个资产，正如您尝试的那样。此外，.obj不是.fbx

您是否尝试过：

WWW www = new WWW ("http://everyday3d.com/unity3d/obj/monkey.obj");
yield return www;
