构建 Unity3D 项目后文本文件为空

问题描述

在运行时，我记录了我想在构建中播放的输入。因此，我在 Resources 目录下创建了一个 txt 文件，在整个运行时使用 StreamWriter 填充文本。关闭项目后，内容在场景模式下保留在那里，但在构建和运行它之后不会。我已经在网上搜索了一段时间，但没有找到与我的问题相关的任何内容。我尝试使用 StreamingAssets 文件夹，但我也没有让它工作。感谢您的帮助。

    if (!Directory.Exists("Assets/Resources/Recordings"))
    {
        Directory.CreateDirectory("Assets/Resources/Recordings");
    }

    if (!File.Exists("Assets/Resources/Recordings/Challenge1.txt"))
    {
        File.WriteallText("Assets/Resources/Recordings/Challenge1.txt","");
    }

编辑：切换（模式）

     case Mode.Record:
        oldSequence.init ();
        currentSequence.init ();

        inputRecordStream = new StreamWriter (FilePath,false); // will overwrite new file Stream
        if (inputRecordStream.ToString () == "")
        {
            Stop ();
            Debug.Log ("InputReplay: StreamWriter(" + FilePath + "),file not found ?");
            return false;
        }
        else
        {
            inputRecordStream.AutoFlush = true;
            SetInputStd ();
        }
        break;

记录方法：

private void Record(float time)
{
    currentSequence.init ();
    currentSequence.t = time;

    // store only true boolean
    foreach (KeyCode vkey in System.Enum.GetValues(typeof(KeyCode)))
    {
        if (Input.GetKey (vkey))
            currentSequence.gK.Add (vkey);
        if (Input.GetKeyDown (vkey))
            currentSequence.gKD.Add (vkey);
        if (Input.GetKeyUp (vkey))
            currentSequence.gKU.Add (vkey);
    }

    currentSequence.mP = Input.mousePosition;

    currentSequence.mWP = Camera.main.ScreenToWorldPoint (currentSequence.mP);

    currentSequence.mSD = Input.mouseScrollDelta;

    foreach (string virtualAxis in AxisList)
        currentSequence.vA.Add (Input.GetAxis (virtualAxis));

    foreach (string ButtonName in ButtonList)
    {
        if (Input.GetButton (ButtonName))
            currentSequence.vB.Add (ButtonName);
        if (Input.GetButtonDown (ButtonName))
            currentSequence.vBD.Add (ButtonName);
        if (Input.GetButtonUp (ButtonName))
            currentSequence.vBU.Add (ButtonName);
    }

    // only write if something changed
    if (AnyChange(oldSequence,currentSequence))
    {
        //Debug.Log (JsonUtility.ToJson (newSequence));
        inputRecordStream.WriteLine (JsonUtility.ToJson (currentSequence));
        oldSequence = currentSequence;
    }
}

解决方法

File.WriteAllText("Assets/Resources/Recordings/Challenge1.txt",""); 

使用 File.WriteAllText(string path string text ) 时，请确保包含要写入文件的数据。您只包含了“”，它不会向文件写入任何字符。

要导入要在运行时使用的资产，您可以使用 Resources.Load(string path)。这将允许您在运行时访问统一脚本中的文件。
