本文档介绍了如何使用Unity的BuildPipeline.BuildAssetBundles方法创建AssetBundles，并提供了针对iOS、Android和Windows平台的构建示例。同时，文章提及了如何根据资源名称获取依赖AssetBundles，并通过WWW.LoadFromCacheOrDownload进行加载。适用于Unity开发者学习AssetBundle管理和加载流程。

using UnityEngine;  
using System.Collections;  
using System.IO;  
using System.Collections.Generic;  
using System;  
using UnityEditor;  
  
/// <summary>  
/// 创建AssetBundle  
/// </summary>  
public class CreateAssetBundle : MonoBehaviour  
{  
	//生成到的目录  
	public static string Build2Path = Application.dataPath + "/BuildABs";  
  
	public static BuildTarget target = BuildTarget.iOS;  
  
	[MenuItem("CYH_Tools/AB_Packager/Build_2_IPhone")]  
	public static void BuildiPhoneResource()  
	{  
		target = BuildTarget.iOS;  
		BuildAssetResource(target);  
	}  
  
	[MenuItem("CYH_Tools/AB_Packager/Build_2_Android")]  
	public static void BuildAndroidResource()  
	{  
		target = BuildTarget.Android;  
		BuildAssetResource(target);  
	}  
  
	[MenuItem("CYH_Tools/AB_Packager/Build_2_Windows")]  
	public static void BuildWindowsResource()  
	{  
		target = BuildTarget.StandaloneWindows;  
		BuildAssetResource(target);  
	}  
  
	private static void BuildAssetResource(BuildTarget target)  
	{  
		//文件已经存在就删除  
		if (Directory.Exists(Build2Path))  
		{  
			Directory.Delete(Build2Path, true);  
		}  
		//文件不存在就创建  
		if (!Directory.Exists(Build2Path))  
		{  
			Directory.CreateDirectory(Build2Path);  
		}  
  
		//打包  
		BuildPipeline.BuildAssetBundles(Build2Path, BuildAssetBundleOptions.None, target);  
	}  
}

然后根据我们需要加载的资源名称，获得所有依赖资源：
            string[] dps = mainfest.GetAllDependencies(realName);
            AssetBundle[] abs = new AssetBundle[dps.Length];
            for (int i = 0; i < dps.Length; i++)
            {
                string dUrl = Cdn + dps[i];
                WWW dwww = WWW.LoadFromCacheOrDownload(dUrl, mainfest.GetAssetBundleHash(dps[i]));
                yield return dwww;
                abs[i] = dwww.assetBundle;
            }
其中realName是想加载的AssetBundle的名字，需要带扩展名。
