场景打包AssetBundle注意事项

先上打包代码

public class BuildAssetBundle
{


    [MenuItem("打包/场景")]
    public static void BuildScenesWindows()
    {
        BuildScenes();
       
    }

    // 打包Scenes
    private static void BuildScenes()
    {
        // 指定场景文件夹和输出路径
        string scenePath = Application.dataPath + "/scene";
        string outPath = Application.streamingAssetsPath + "/";

        if (Directory.Exists(scenePath))
        {
            // 创建输出文件夹
            if (!Directory.Exists(outPath)) Directory.CreateDirectory(outPath);

            // 查找指定目录下的场景文件
            string[] scenes = GetAllFiles(scenePath, "*.unity");
            for (int i = 0; i < scenes.Length; I++)
            {
                string url = scenes[i].Replace("\\", "/");
                Debug.Log(url);
                int index = url.LastIndexOf("/");
                string scene = url.Substring(index + 1, url.Length - index - 1);
                string msg = string.Format("打包场景{0}", scene);
                EditorUtility.DisplayProgressBar("信息", msg, 0f);
                scene = scene.Replace(".unity", ".scene");
                Debug.Log(string.Format("打包场景{0}到{1}", url, outPath + scene));
                BuildPipeline.BuildPlayer(scenes, outPath + scene, EditorUserBuildSettings.activeBuildTarget, BuildOptions.BuildAdditionalStreamedScenes);
                AssetDatabase.Refresh();
            }
            EditorUtility.ClearProgressBar();
            Debug.Log("所有场景打包完毕");
        }
    }

    /// <summary> 获取文件夹和子文件夹下所有指定类型文件 </summary>
    private static string[] GetAllFiles(string directory, params string[] types)
    {
        if (!Directory.Exists(directory)) return new string[0];
        string searchTypes = (types == null || types.Length == 0) ? "*.*" : string.Join("|", types);
        string[] names = Directory.GetFiles(directory, searchTypes, SearchOption.AllDirectories);
        return names;
    }
}

再上加载代码

public class AppStart : MonoBehaviour
{
    string  AB_path = Application.streamingAssetsPath+"/"+ "test.scene";
    // Start is called before the first frame update
    void Start()
    {
        DontDestroyOnLoad(this.gameObject);
        AssetBundle AB_PACK = AssetBundle.LoadFromFile(AB_path);
        SceneManager.LoadScene("test");


    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

过程中遇到的问题

1. 天空盒子丢失
   原因：场景打包成assetbundle的时候，unity不会打包一些自带相关的资源
   解决办法：使用第三方天空盒子

2.shader丢失
原因：场景打包成assetbundle的时候，unity不会打包一些自带相关的资源
解决办法：在project settings>Graphics下设置添加要使用的shader

3.场景一些烘培的贴图丢失
原因：场景打包成assetbundle的时候，unity不会打包一些自带相关的资源
解决办法：在project settings>Graphics下设置
