我为我的一个3D资产创建了一个资产包,并通过在运行时下载该捆绑包进行测试,其工作正常 . 现在我想在ARCore中使用相同的资产捆绑程序 . 我想加载Andy 3D资产不是预制件,而是从外部服务器加载AssetBundle . 我在ARCore中尝试过AssetBundling,但它没有用 .

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//using UnityEditor;

public class DownloadAssetBundle : MonoBehaviour {
    public static DownloadAssetBundle instance = null;
    [HideInInspector]public string url;
    [HideInInspector]public GameObject assetDemo;
    // Use this for initialization
    void Awake()
    {
        if (instance == null)


            instance = this;


        else if (instance != this)

            Destroy(gameObject);
    }
    void Start () {
        url = "https://s3.amazonaws.com/bucketname/myasset";
        StartCoroutine (DownloadAsset());
    }

    IEnumerator DownloadAsset()
    {
        WWW www = new WWW (url);
        yield return www;
        AssetBundle assetbundle = www.assetBundle;
            assetDemo = (GameObject)assetbundle.LoadAsset ("DinningTable");
            //Instantiate (assetDemo,Vector3.zero,Quaternion.identity);

    }
}

通过使用上面的代码我从我的AWS S3桶下载AssetBundle,我也为这个脚本创建了实例,因为我想在ExampleController中实例化“assetDemo”变量gameobject,我也做了

andyObject = Instantiate(DownloadAssetBundle.instance.assetDemo, hit.Pose.position, hit.Pose.rotation);

但它没有工作!任何人都可以帮助我摆脱它
