本文详细介绍如何在Unity中使用自定义脚本构建AssetBundle（AB包），并将其上传至服务器如阿里云OSS，同时提供了加载AB包的示例代码，展示了从缓存或下载AB包到实例化资源的全过程。

首先，是如何打包AB包。首先编写AssetBulider脚本，注意需要引用UnityEditor。将这个编辑器脚本放到Asset/Editor文件夹中

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;

public class AssetBuilder : MonoBehaviour {
	
	[MenuItem("Assets/Get AssetBundle names")]
	static void GetAssetBundleNames(){//获取所有AB名称
		var names = AssetDatabase.GetAllAssetBundleNames();
		foreach (var name in names)
		{
			Debug.Log("AB:"+name);//显示全部AB包名称	
		}
	}
	// Use this for initialization

	[MenuItem("Assets/Build Asset Bundles")]
	static void BulidAssets(){
		BuildPipeline.BuildAssetBundles("Assets/Bundles/Win",BuildAssetBundleOptions.None,BuildTarget.StandaloneWindows);

	}
}

接下来是将AB包上传到服务器或阿里云OSS中复制资源的URL

LoadAssetBundle脚本是如何加载AB包

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class LoadAssetsBundles : MonoBehaviour {

	// Use this for initialization
	public Image img;
	void Start () {
		
	}
	public void LoadAB(){
		StartCoroutine(StartLoad());
	}
	
	// Update is called once per frame
	void Update () {
		
	}
	IEnumerator StartLoad(){
		while(!Caching.ready)
			yield return null;
		int version = 1;
		WWW www = WWW.LoadFromCacheOrDownload("阿里云的链接",version);
		yield return www;
		AssetBundle bundle = www.assetBundle;
		print("准备加载网络资源");
		var prefab = bundle.LoadAsset("NSSUI");
		GameObject go = (GameObject)Instantiate(prefab);
		print("加载完毕");
		bundle.Unload(false);
		www.Dispose();
	} 

}
