Csharp 在我重新启动游戏之前，streamWriter 不会应用更改

只需使用AssetDatabase.Refresh刷新Unity中的assets资源 .

However

当玩家创建一个新关卡时，我使用这个

请注意，这些都不适用于内置应用程序！

构建应用程序后，Resources是read-only.不管怎样，请注意Best practices -> Resources

Don't use it!

您可能更希望将默认文件存储在StreamingAssets中，使用Application.streamingassetsPath，然后在构建中使用Application.persistentDataPath，并回退到streamingAssetsPath以实现只读(同样，构建后StreamingAssets是只读的)

比如说

public string ReadlevelsFile()
{
    try
    {
#if UNITY_EDITOR
        // In the editor always use "Assets/StreamingAssets"
        var filePath = Path.Combine(Application.streamingAssetsPath, "Levels.txt");
#else
        // In a built application use the persistet data
        var filePath = Path.Combine(Application.persistentDataPath, "Levels.txt");
        
        // but for reading use the streaming assets on as fallback
        if (!File.Exists(filePath))
        {
            filePath = Path.Combine(Application.streamingAssetsPath, "Levels.txt");
        }
#endif
        return File.ReadAllText(filePath);
    }
    catch (Exception e)
    {
        Debug.LogException(e);
        return "";
    }
}

public void WriteLevelsFile(string content)
{
    try
    {
#if UNITY_EDITOR
        // in the editor always use "Assets/StreamingAssets"
        var filePath = Path.Combine(Application.streamingAssetsPath, "Levels.txt");
        // mke sure to create that directory if not exists yet
        if(!Directory.Exists(Application.streamingAssetsPath))
        {
            Directory.CreateDirectory(Application.streamingAssetsPath);
        }
#else
        // in a built application always use the persistent data for writing
        var filePath = Path.Combine(Application.persistentDataPath, "Levels.txt");
#endif
        
        File.WriteAllText(filePath, content);

#if UNITY_EDITOR
        // in Unity need to refresh the data base
        UnityEditor.AssetDatabase.Refresh();
#endif
    }
    catch(Exception e)
    {
        Debug.LogException(e);
    }
}
