[Unity基础]打包与读取AssetBundle

1.打包prefab

using UnityEngine;using System.Collections;using UnityEditor;//选择的物体放在不同的ABpublic class CreateAB_Respectively : MonoBehaviour {    [MenuItem("Custom Editor/Create AssetBunldes Main")]    static void CreateAssetBunldesMain()    {        //获取在Project视图中选择的所有游戏对象        Object[] SelectedAsset = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);        //遍历所有的游戏对象        foreach (Object obj in SelectedAsset)        {            string sourcePath = AssetDatabase.GetAssetPath(obj);            //本地测试：建议最后将Assetbundle放在StreamingAssets文件夹下，如果没有就创建一个，因为移动平台下只能读取这个路径            //StreamingAssets是只读路径，不能写入            //服务器下载：就不需要放在这里，服务器上客户端用www类进行下载。            string targetPath = Application.dataPath + "/StreamingAssets/" + obj.name + ".assetbundle";            if (BuildPipeline.BuildAssetBundle(obj, null, targetPath, BuildAssetBundleOptions.CollectDependencies))            {                Debug.Log(obj.name + "资源打包成功");            }            else            {                Debug.Log(obj.name + "资源打包失败");            }        }        //刷新编辑器        AssetDatabase.Refresh();    }}

using UnityEngine;using System.Collections;using UnityEditor;//选择的物体放在同一个ABpublic class CreateAB_Together : MonoBehaviour {    [MenuItem("Custom Editor/Create AssetBunldes ALL")]    static void CreateAssetBunldesALL()    {        Caching.CleanCache();        string Path = Application.dataPath + "/StreamingAssets/ALL.assetbundle";        Object[] SelectedAsset = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);        foreach (Object obj in SelectedAsset)        {            Debug.Log("Create AssetBunldes name :" + obj);        }        //这里注意第二个参数就行        if (BuildPipeline.BuildAssetBundle(null, SelectedAsset, Path, BuildAssetBundleOptions.CollectDependencies))        {            AssetDatabase.Refresh();        }        else        {        }    }}

2.打包场景

using UnityEngine;using System.Collections;using UnityEditor;//打包场景//把11.unity场景文件打包到MyScene.unity3d文件中，//所以在解包的时候也应当是先解开MyScene.unity3d，然后在去加载11.unity场景，//无需在ProjectSetting中注册新场景。public class CreateAB_Scene : MonoBehaviour {[MenuItem("Custom Editor/Create Scene")]static void CreateSceneALL (){//清空一下缓存Caching.CleanCache();        string Path = Application.dataPath + "/StreamingAssets/" + "/MyScene.unity3d";string[] levels = {"Assets/TestAB/11.unity"};    //打包场景        BuildPipeline.BuildStreamedSceneAssetBundle(levels,Path,BuildTarget.StandaloneWindows64,BuildOptions.BuildAdditionalStreamedScenes);    //BuildPipeline.BuildPlayer( levels, Path, BuildTarget.WebPlayer, BuildOptions.BuildAdditionalStreamedScenes);AssetDatabase.Refresh ();}}

3.读出AssetBundle

using UnityEngine;using System.Collections; public class RunScript : MonoBehaviour {    //不同平台下StreamingAssets的路径是不同的，这里需要注意一下。    public static readonly string PathURL =#if UNITY_ANDROID"jar:file://" + Application.dataPath + "!/assets/";#elif UNITY_IPHONEApplication.dataPath + "/Raw/";#elif UNITY_STANDALONE_WIN || UNITY_EDITOR"file://" + Application.dataPath + "/StreamingAssets/";#else        string.Empty;#endif void OnGUI(){if(GUILayout.Button("Main Assetbundle")){            StartCoroutine(LoadMainGameObject(PathURL + "Cube.assetbundle"));            StartCoroutine(LoadMainGameObject(PathURL + "Cube2.assetbundle"));}if(GUILayout.Button("ALL Assetbundle")){StartCoroutine(LoadALLGameObject(PathURL + "ALL.assetbundle"));}        if (GUILayout.Button("Open Scene"))        {            StartCoroutine(LoadScene());        }} //读取一个资源private IEnumerator LoadMainGameObject(string path){        WWW bundle = WWW.LoadFromCacheOrDownload(path, 5);        yield return bundle;        yield return Instantiate(bundle.assetBundle.mainAsset);        bundle.assetBundle.Unload(false);} //读取全部资源private IEnumerator LoadALLGameObject(string path){        WWW bundle = WWW.LoadFromCacheOrDownload(path, 5);yield return bundle; //通过Prefab的名称把他们都读取出来        Object obj0 = bundle.assetBundle.Load("Cube");        Object obj1 = bundle.assetBundle.Load("Cube2"); //加载到游戏中yield return Instantiate(obj0);yield return Instantiate(obj1);bundle.assetBundle.Unload(false);}    //读取场景private IEnumerator LoadScene(){        WWW download = WWW.LoadFromCacheOrDownload("file://" + Application.dataPath + "/StreamingAssets/" + "/MyScene.unity3d", 1);yield return download;var bundle = download.assetBundle;  Application.LoadLevel ("11");}}
