请 don't recommend 我 Unity3d official links 我试过了它并不全面，也没有提供必要的细节 . 我是新手，将在Unity3d中制作 AssetBundles . 到目前为止，在统一官员docs的帮助下，下面给出的是什么 .

/// <summary>
/// AssetBundles are exported from the editor using script code. (This is similar to the 4.x approach.)
/// The following script exports AssetBundles.
/// </summary>
public class AssetBundleCreate {

    [MenuItem("Assets/Build AssetBundles")]
    static void BuildAllAssetBundles() {
        Debug.Log("asset build");
        BuildPipeline.BuildAssetBundles("Assets/AssetBundles");
    }

    [MenuItem("Assets/Get AssetBundle Names")]
    static void GetNames() {
        var names = AssetDatabase.GetAllAssetBundleNames();
        foreach(var name in names){
            Debug.Log("AssetBundle name is : " + name);
        }
    }
}

但是代码没有生成任何资产包而是它已经制作了 . 文件和.abc扩展名文件 . 我缺少什么，也 Share proper guide about Creating and Downloading Asset bundle from local server/pc in Unity 5

    我们正在创建的Assetbundle是 platform specific: 要创建AssetBundle，只需编写一个C＃脚本并将其放在 Editor 文件夹中： Assets > Editor 这里我提供ex . android特定平台：

    using UnityEngine;
using System.Collections;
using UnityEditor;

public class ExportAssetBundles : Editor {
    [MenuItem("Assets/Build AssetBundle")]
    static void ExportResource()
    {
        string path = "Assets/AssetBundle/myAssetBundle.unity3d";
        Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);
        BuildPipeline.BuildAssetBundle(Selection.activeObject, selection, path,
                                       BuildAssetBundleOptions.CollectDependencies
                                     | BuildAssetBundleOptions.CompleteAssets,BuildTarget.Android);
    }
}

    之后你可以放置target.unity3d文件 locally or on remote server ：记住在android平台上我们必须使用下面提供的WWW类 . [imp]现在我们还可以在assetsbundle中包含脚本：只需尝试下面的脚本，你必须将这个脚本附加到你要导入AssetBundle的场景中的空游戏对象：

    using UnityEngine;
using System.Collections;

public class AssetBundleAugmenter : MonoBehaviour {

	public string AssetName;
	public int Version;
	
	private GameObject mBundleInstance = null;

	
	void Start() {  
		StartCoroutine(DownloadAndCache());

		}

	// Update is called once per frame
	IEnumerator DownloadAndCache() {

		while(!Caching.ready)
			yield return null;
		
		// example URL of file on PC filesystem (Windows)
		// string bundleURL = "file:///D:/Unity/AssetBundles/MyAssetBundle.unity3d";
		
		// example URL of file on Android device SD-card
		string bundleURL = "file:///mnt/sdcard/AndroidCube.unity3d";
		
		using (WWW www = WWW .LoadFromCacheOrDownload(bundleURL, Version)) {
			yield return www;
			
			if (www .error != null)
				throw new UnityException("WWW Download had an error: " + www .error);

			// Load and retrieve the AssetBundle
			AssetBundle bundle = www .assetBundle;

			// Load the assembly and get a type (class) from it
			var assembly = System.Reflection.Assembly.Load("txt.bytes");
			var type = assembly.GetType("MyClassDerivedFromMonoBehaviour");

			// Instantiate a GameObject and add a component with the loaded class
			GameObject go = new GameObject();
			go.AddComponent(type);

			if (AssetName == "") {
				mBundleInstance = Instantiate (bundle.mainAsset) as GameObject;
			}
			else {
				mBundleInstance = Instantiate(bundle.LoadAsset (AssetName)) as GameObject;
			}
		
	
			// Unload the AssetBundles compressed contents to conserve memory
			bundle.Unload(false);

		}
	}
	
}

    如果您对导出脚本不感兴趣，那么只需从给定脚本中跳过以下部分：

    // Load the assembly and get a type (class) from it
			var assembly = System.Reflection.Assembly.Load("txt.bytes");
			var type = assembly.GetType("MyClassDerivedFromMonoBehaviour");

			// Instantiate a GameObject and add a component with the loaded class
			GameObject go = new GameObject();
			go.AddComponent(type);
