# 實驗室框架修正

:::info

實驗室框架使用 Unity 引擎版本 2019.2.10f1。
如欲使用新版 Unity 版本，請參閱 [升級 Unity 引擎版本](/Vdw7uwrOSxGLSiuze7rXPA)

## LabTools

:::info
Application.persistentDataPath 對應的位置在 pico 裡是 `Android\data\{安裝包名}\files`
:::

        public static string DataPath => 
#if UNITY_ANDROID
            Application.persistentDataPath
#else        
            Application.dataPath
#endif            
        ;

## LabDataManager

private string labDataSavePath => LabTools.DataPath + "/TestData";

_saveDataPath = LabTools.DataPath + "/Output";

            string testStorePath = Path.Combine(LabTools.DataPath, "TestStore");
            if (!Directory.Exists(testStorePath))
            {
                Directory.CreateDirectory(testStorePath);
            }
            _applicationLifecycle = new SimpleApplicationLifecycle();


            _client = new DataSyncClient(new UnityApplicationFolderProvider(testStorePath),
                _applicationLifecycle, options, _userId);

:::info
Android 用 StreamWriter 寫檔可能會有斷尾情事。
可以改最底下 LabDataWriter

    public class LabDataWriter
    {        
        private string path;
        public LabDataWriter(string path)
        {
            this.path = path;
        }
        public void WriteData(LabDataBase data)
        {
            File.AppendAllText(path, data.ToJson());
        }
        public void WriterDispose()
        {
            
        }
    }

:::

## LabExtension

return JsonConvert.SerializeObject(o, new JsonSerializerSettings()
            {
                ReferenceLoopHandling = ReferenceLoopHandling.Ignore, // 改 ignore 避免循環引用 (Force 會直接閃退不報錯)
                NullValueHandling = NullValueHandling.Include                
            })

## 變更 PlayerSettings


## SpVoice
<!-- > 實驗室眾人踩到的無底陷坑 -->

如果你的 code 有出現

using SpeechLib;

或

SpVoice

請註解掉！！！
它會讓其所處的函式炸掉，但又不會報錯，非常噁心。
<!-- 並且請將 Plugins/Interop.SpeechLip 除外 -->

替代方案請見峰銘筆記：https://hackmd.io/nmp_AZA6T5eK_424x8h5LA#%E6%8A%8ASPVoice%E8%A8%BB%E8%A7%A3%EF%BC%8C%E6%9B%BF%E6%8F%9B%E6%88%90google%E8%AA%9E%E9%9F%B3

## TroubleShoot

### 進到 MainUI 畫面空白，報錯 数据文件不存在！


改 LabTools 的 `GetData()`

        public static T GetData<T>(string dataName, string filePath = "/GameData") where T : LabDataBase
        {
            // folder
            string path = DataPath + filePath;
            if(filePath.StartsWith("/StreamingAssets/")) // Android 的 Streaming Assets
            {
                path = Path.Combine(Application.streamingAssetsPath, filePath.Replace("/StreamingAssets/", ""));
            }
            // combine file name
            path = Path.Combine(path, typeof(T).Name, dataName + ".json");  

            // StreamReader sr = new StreamReader(path);
            // var data = JsonConvert.DeserializeObject<T>(sr.ReadToEnd());
            // sr.Close();
            var req = UnityWebRequest.Get(path);
            req.SendWebRequest();
            while (!req.isDone) { }

            if(req.isNetworkError || req.isHttpError)
            {
                Debug.LogError("数据文件不存在！"+path);
                Debug.LogError("Reason: "+req.error);
                return default;
            }

            var data = JsonConvert.DeserializeObject<T>(req.downloadHandler.text);
            return data;
        }

### LabDataManager 欄位空白

:::warning
在某些舊版框架，資料蒐集之 `LabDataManager` 可能不在 `GameDataManager` 底下，有遇過在 `LabDataTestComponent`底下的情形

LabDataTestComponent.LabDataManager.SendData(new LabLeftEyeData(Vector3.zero, Vector3.zero, -1, leftEyeopenness, leftEyePosition));
LabDataTestComponent.LabDataManager.SendData(new LabRightEyeData(Vector3.zero, Vector3.zero, -1, leftEyeopenness, rightEyePosition));
LabDataTestComponent.LabDataManager.SendData(new LabCombinedEyeData(combinedEyeGazePoint, combinedEyeGazeVector, -1, -1, Vector3.zero));
