U3D assetbundle加载

 1 using UnityEngine;
 2 using System.Collections;
 3 public class testLoadFromAB : MonoBehaviour {

 5     IEnumerator DownloadAndCache()
 6     {
 7         while (!Caching.ready)
 8             yield return null;
 9 
10         //注意，从本地加载时，必须使用前缀 file:///或file://，从网络加载则使用 http://，这两种协议可以在iphone和WINDOWS, 安卓上通用
11         //UNITY MANUAL:
12         //http://, https:// and file:// protocols are supported on iPhone. 
13         //ftp:// protocol support is limited to anonymous downloads only. Other protocols are not supported.
14         WWW www = WWW.LoadFromCacheOrDownload ("file:///Z:/unity/learn-test/Assets/AssetBundles/cubes.unity3d", 22);
15         yield return www;
16         if(!string.IsNullOrEmpty (www.error)){//有些平台不支持string为null，这种写法可以避免意外
17             Debug.LogError (www.error);
18             yield break;
19         }
20 
21         AssetBundle bundle = www.assetBundle;
22 
23         //注意必须使用Instantiate实例化出来才能将两个CUBE显示到场景中
24         GameObject cube1 = Instantiate (bundle.LoadAsset ("DecalCube2")) as GameObject;
25         GameObject cube2 = Instantiate (bundle.LoadAsset ("DecalCube3")) as GameObject;
26 
27     }
28     // Use this for initialization
29     void Start () {
30         StartCoroutine ("DownloadAndCache");
31     }
32     
33     // Update is called once per frame
34     void Update () {
