U3D-Assetbundle加载

首先 写个打包成Assetbundle的脚本 放在Editor下

using UnityEngine;

using System.Collections;

using UnityEditor;



public class NewBehaviourScript :ScriptableObject

{

    [MenuItem("chen/create assetbundle main")]

    static void cam()

    { 

        object[] selected = Selection.GetFiltered(typeof(object), SelectionMode.DeepAssets);

        foreach (Object obj in selected)

        { 

            string source = AssetDatabase.GetAssetPath(obj);

            string target = Application.dataPath + "/chensiyang/" + obj.name + ".assetbundle";

            if (BuildPipeline.BuildAssetBundle(obj, null, target, BuildAssetBundleOptions.CollectDependencies))

                Debug.Log("yes");

            else

                Debug.Log("wrong");

        }

    }

    [MenuItem("chen/create assetbundle all")]

    static void caa()

    { 

        Object[] selectedall = Selection.GetFiltered(typeof(object),SelectionMode.DeepAssets);

        string aim = Application.dataPath + "/chensiyang/all.assetbundle";

        if (BuildPipeline.BuildAssetBundle(null, selectedall, aim, BuildAssetBundleOptions.CollectDependencies))

            Debug.Log("all");

        else Debug.Log("wrong");

    }



}

 

然后加载包

using UnityEngine;

using System.Collections;

using System.IO;



public class NewBehaviourScript2 : MonoBehaviour {

    private  static string path ="file://"+Application.dataPath+"/chensiyang/";

    // Use this for initialization

    void Start () {

        print(Application.dataPath);



        StartCoroutine(load(path + "all.assetbundle"));

    }

    

    // Update is called once per frame

    void Update () {

    //if(Input.GetMouseButtonDown(0))

        

    }

    private IEnumerator load(string str)

    { 

        WWW data = new WWW(str);

        yield return data;

         Instantiate(data.assetBundle.Load("tv"));

        data.assetBundle.Unload(false);



    }

}

 还有一种加载方式，避免重复下载

 private IEnumerator load(string str)

    {

        //WWW data = new WWW(str);

        //yield return data;

        //Instantiate(data.assetBundle.Load("tv"));

        //data.assetBundle.Unload(false);

        WWW data = WWW.LoadFromCacheOrDownload(str, 5);

        yield return data;

       yield return Instantiate(data.assetBundle.Load("tv"));

        data.assetBundle.Unload(false);

    }

}
