unity生成AB包

生产AB包,编辑器脚本放在Editor文件夹下(切记)

using UnityEngine;
using UnityEditor;
using System.IO;

public class BuildAssetBundle : MonoBehaviour
{
    [MenuItem("Tools/打AB包")]
    public static void BuildAB()
    {
        string dir = Application.streamingAssetsPath;    //定义AB包路径：工程目录下的StreamingAssets
        if (Directory.Exists(dir) == false)//如果不存在文件夹，那么新建一个
        {
            Directory.CreateDirectory(dir);
        }
        BuildPipeline.BuildAssetBundles(dir,
            BuildAssetBundleOptions.ChunkBasedCompression, BuildTarget.WebGL);
        AssetDatabase.Refresh();
        Debug.LogError("打包完成");
    }
}

 

1.先把你需要的对象变成预制体,选中预制体,给预制体添加AssetBundle(如下图)

 

 

 

 

2.设置完成点击Tools/打AB包 等待即可

完成之后文件夹会出现 如下图文件

 

 

3.然后把第一个文件复制到自己的服务器即可

 

加载AB包

1.两种方式脚本如下

using System.Collections;
using UnityEngine;
using UnityEngine.Networking;

public class Load_AB : MonoBehaviour
{
    private void Start()
    {
        StartCoroutine(LoadWWW());
        StartCoroutine(FromWebRequest());
    }
    private IEnumerator FromWebRequest()
    {
        string path = @"http://192.168.1.80:8088/unity/model.ab";
        UnityWebRequest webRequest = UnityWebRequestAssetBundle.GetAssetBundle(path);
        yield return webRequest.SendWebRequest();
        AssetBundle assetBundle = DownloadHandlerAssetBundle.GetContent(webRequest);
        //object obj = assetBundle.LoadAsset("Image");
        //Instantiate((GameObject)obj, FindObjectOfType<Canvas>().transform);
        object[] objects = assetBundle.LoadAllAssets();
        foreach (var item in objects)
        {
            Instantiate((GameObject)item, FindObjectOfType<Canvas>().transform);
        }
        yield return null;
    }

    private WWW Loadab;

    private IEnumerator LoadWWW()
    {
        Loadab = new WWW("http://192.168.1.80:8088/unity/model.ab");  // 路径可以根据自己需求来修改
        yield return Loadab;
        if (Loadab.error != null)
        {
            Debug.Log(Loadab.error);
        }
        else
        {
            object[] objects = Loadab.assetBundle.LoadAllAssets();
            foreach (var item in objects)
            {
                Instantiate((GameObject)item, FindObjectOfType<Canvas>().transform);
            }
        }
    }
}

 

如果没有服务器可以配置一个本地服务器 (iis管理器)

本地搜索iis打开如下图
