Unity資產包

Question

我正在爲使用Unity遊戲引擎的遊戲創建編輯器，並且我想讓設計師製作新的法術。我試圖達到的目標是設計師將下載一個Unity粒子系統（或GameObject），將其保存在電腦上，併爲遊戲提供完整的路徑。然後遊戲應該加載對象並將其用作新咒語的粒子。

我需要能夠在運行時從文件夾加載Unity GameObject（粒子系統）。我使用資產包嘗試了它，但是我不知道如何使用資產包，當我只想從計算機（本地文件系統）下載文件而非服務器時。資產捆綁包在Debug中完美工作，但在構建和運行時卻沒有（它嘗試連接到某個服務器）。 我使用Asset Bundles的默認腳本：

public class LoadAssets : MonoBehaviour 
    public const string AssetBundlesOutputPath = "/AssetBundles/"; 
    public string assetBundleName; 
    public string assetName; 

    public GameObject loadedObject; 
    public bool finished; 
    public MessageWindow messWindow; 

    // Use this for initialization 
    //originally was start here might create problems 
    public IEnumerator Begin() 
    { 
     messWindow.changeMessageAndShow("Asset " + assetName + " is loading.","Loading"); 
     yield return StartCoroutine(Initialize()); 

     // Load asset. 
     yield return StartCoroutine(InstantiateGameObjectAsync (assetBundleName, assetName)); 
     finished=true; 
     messWindow.Close(); 
    } 

    public GameObject LoadObject() 
    { 
     StartCoroutine(Begin()); 
     //TODO wait for end of couroutine 
     return loadedObject; 
    } 

    // Initialize the downloading url and AssetBundleManifest object. 
    protected IEnumerator Initialize() 
    { 
     // Don't destroy this gameObject as we depend on it to run the loading script. 
     DontDestroyOnLoad(gameObject); 

     // With this code, when in-editor or using a development builds: Always use the AssetBundle Server 
     // (This is very dependent on the production workflow of the project. 
     // Another approach would be to make this configurable in the standalone player.) 
#if DEVELOPMENT_BUILD || UNITY_EDITOR 
     AssetBundleManager.SetDevelopmentAssetBundleServer(); 
#else 
     // Use the following code if AssetBundles are embedded in the project for example via StreamingAssets folder etc: 

     // Or customize the URL based on your deployment or configuration 
     //AssetBundleManager.SetSourceAssetBundleURL("http://www.MyWebsite/MyAssetBundles"); 
#endif 
     AssetBundleManager.SetSourceAssetBundleURL(Application.dataPath + "/"); 

     // Initialize AssetBundleManifest which loads the AssetBundleManifest object. 
     var request = AssetBundleManager.Initialize(); 
     if (request != null) 
      yield return StartCoroutine(request); 
    } 

    protected IEnumerator InstantiateGameObjectAsync (string assetBundleName, string assetName) 
    { 
     // This is simply to get the elapsed time for this phase of AssetLoading. 
     float startTime = Time.realtimeSinceStartup; 

     // Load asset from assetBundle. 
     AssetBundleLoadAssetOperation request = AssetBundleManager.LoadAssetAsync(assetBundleName, assetName, typeof(GameObject)); 
     if (request == null) 
      yield break; 
     yield return StartCoroutine(request); 

     // Get the asset. 
     GameObject prefab = request.GetAsset<GameObject>(); 

     if (prefab != null) 
     { 
      loadedObject = GameObject.Instantiate(prefab);    
      DontDestroyOnLoad(loadedObject); 
     } 

     // Calculate and display the elapsed time. 
     float elapsedTime = Time.realtimeSinceStartup - startTime; 
     Debug.Log(assetName + (prefab == null ? " was not" : " was")+ " loaded successfully in " + elapsedTime + " seconds"); 
    } 
} 

非常感謝。

要從本地系統加載資源包，您需要本地AssetBundle服務器。啓用本地資產服務器時，必須構建AssetBundles並將其放置在項目根目錄中顯式名爲AssetBundles的文件夾中，該文件夾與Assets文件夾位於同一級別。

構建的AssetBundles將可供編輯人員使用，並且本地運行的所有構建都可以訪問本地網絡上的編輯器。

使用Assets>AssetBundles>Local AssetBundle Server啓用本地AssetBundle服務器。
