[unity3d]unity中打包成.unity3d格式并實

1.首先我們把這段代碼拷貝下來，放進工程，不要托給任何物體，就放在那不要理它。

using UnityEngine; using UnityEditor; public class ExportAssetBundles {     [MenuItem("Export/Build AssetBundle From Selection - Track dependencies")]     static void ExportResource () {         // Bring up save panel         string path = EditorUtility.SaveFilePanel ("Save Resource", "", "New Resource", "unity3d");         if (path.Length != 0) {             // Build the resource file from the active selection.         Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);             BuildPipeline.BuildAssetBundle(Selection.activeObject, selection, path, BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets);             Selection.objects = selection;         }     }     [MenuItem("Export/Build AssetBundle From Selection - No dependency tracking")]     static void ExportResourceNoTrack () {         // Bring up save panel         string path = EditorUtility.SaveFilePanel ("Save Resource", "", "New Resource", "unity3d");         if (path.Length != 0) {             // Build the resource file from the active selection.             BuildPipeline.BuildAssetBundle(Selection.activeObject, Selection.objects, path);         }     } }

當我們創建完，保存好后我，我們會發現菜單的導航欄多了這2項

2.我們在選中我們需要打包的預設物體（也即是Prefab）。然后選中上面的第一項進行打包成.unity3d格式的文件。如圖

3.設置名字，路徑等（路徑很重要，待會加載會用到。）如圖:

4.刷新下。你就會看見這個了:

這個就是我們打包后動態加載的內容。

5. 現在我來說下怎么動態加載它吧,直接上代碼

using UnityEngine; using System.Collections; using System.IO;  public class LoadUnity3d : MonoBehaviour {      // Use this for initialization     void Start()     {          StartCoroutine(LoadScene());      }      // Update is called once per frame     void Update()     {      }      IEnumerator LoadScene()     {         //文件路徑，也就是我們打包的那個         WWW www = new WWW("file:///" + Application.dataPath + "/Bundles/My Prefab.unity3d");         yield return www;         Instantiate(www.assetBundle.mainAsset);     } }

6.我們再新建一個空物體，講我們這個腳本托給他，運行，你就能看見我們的預設也加載出來了。

  效果如下:
