我正在使用Unity的地平面功能放置3D動畫模型。但是，我現在正在使用AssetBundle功能下載此3d模型，并需要使用腳本將其放置在Ground Plane Stage上。但是，當我將其部署到android設備上時，它不會顯示...我正在使用支持GroundPlane檢測的Xiaomi Redmi 3s。我已添加腳本以將資產捆綁包下載到“平面查找器”中AssetbundleDownloadingScript：public class AssetLoader : MonoBehaviour{    public static AssetLoader Instance;    public string url = "myurl";    public int version = 1;    public string AssetName;    //public Text infoText;    public string infoText = "";    AssetBundle bundle;    void Awake()    {        Instance = this;        DownloadAsset();    }    void OnDisable()    {        //AssetBundleManager.Unload(url, version);    }    public void DownloadAsset()    {        // bundle = AssetBundleManager.getAssetBundle (url, version);        //   Debug.Log(bundle);        if (!bundle)            StartCoroutine(DownloadAssetBundle());    }    IEnumerator DownloadAssetBundle()    {        yield return StartCoroutine(AssetBundleManager.downloadAssetBundle(url, version));        bundle = AssetBundleManager.getAssetBundle(url, version);        if (bundle != null)            infoText = "Download Success.....";        else            infoText = "Download error please retry";        GameObject santaasset = bundle.LoadAsset("animation_keyframes_increase_v1", typeof(GameObject)) as GameObject;        //here script attached to plane finder,get 1st child of planefinder        var child = gameObject.transform.GetChild(0);        if (santaasset != null)        {            santaasset.transform.transform.Rotate(new Vector3(0, 180, 0));            santaasset.transform.transform.localScale = new Vector3(0.1f, 0.1f, 0.1f);            santaasset.transform.transform.SetParent(child.transform, false);        }        bundle.Unload(false);    }    public void SetInfoText(string text)    {        //infoText.text = text;    }    void OnGUI()    {        GUILayout.Label("Dummy Label:" + infoText);    }}這是我的場景的屏幕截圖：關于我在做什么錯的任何建議嗎？謝謝。
