AssetBundle的创建

using UnityEngine;
using UnityEditor;
using System.IO;
using System;

public class BuildAssetBundlesFromDirectory 
{
	[@MenuItem("Asset/Build AssetBundles From Directory of Files")]
	static void ExportAssetBundles () 
	{

		string path = AssetDatabase.GetAssetPath(Selection.activeObject);
		Debug.Log("Selected Folder: " + path);
		if (path.Length != 0) 
		{
			path = path.Replace("Assets/", "");
			string [] fileEntries = Directory.GetFiles(Application.dataPath+"/"+path);
            string[] div_line = new string[] { "Assets/" };
			foreach(string fileName in fileEntries) 
			{
                Debug.Log("fileName="+fileName);
                string[] sTemp = fileName.Split(div_line, StringSplitOptions.RemoveEmptyEntries);
                string filePath = sTemp[1];
				
				//int index = filePath.LastIndexOf("/");
                filePath = "Assets/" + filePath;
				//Debug.Log(filePath);
                string localPath = filePath;
				//if (index > 0)
				//localPath += filePath;
                //localPath = "Assets/Prefabs/Binoculars.prefab";
				UnityEngine.Object t = AssetDatabase.LoadMainAssetAtPath(localPath);
				
				if (t != null) 
				{
					Debug.Log(t.name);
                    string bundlePath = "Assets/"+path+"/"  + t.name + ".unity3d";
					Debug.Log("Building bundle at: " + bundlePath);
					//Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);
							
					BuildPipeline.BuildAssetBundle(t, null, bundlePath, BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets);
				}
				 
				
			}
		}
	}
}

从AssetBundle实例化对象

using UnityEngine;
using System.Collections;

public class Test : MonoBehaviour {

	

    
    string url = "http://192.168.2.105:8080/Test/AssetBundle/Cube.unity3d";
    IEnumerator Start()
    {
        // Start a download of the given URL
        // 开始从指定路径下载
        WWW www = WWW.LoadFromCacheOrDownload(url, 1);
        // Wait for download to complete
        // 等待下载完成
        yield return www;
        if (www.error != null)

        {

            Debug.Log (www.error);

            yield  return null;

        }

            Instantiate(www.assetBundle.mainAsset,transform.position,Quaternion.identity);
        
    }
}

apache-tomcat-6.0.37

 WWW www = WWW.LoadFromCacheOrDownload(url, 1);

改成

 WWW www = new WWW(url);
