Find Editor and Player Log Files in Unity

Unity Editor Logs

Here is where the editor logs are stored:

“~” corresponds to the Home folder of your user:

You can also directly open the logs via: “Window” -> “General” -> “Console” and click on “Open Editor Log”.

Player Logs

Here is where the game logs are stored in a build version (player log):

Check the documentation for other informations.

Real-Time Logs

This feature is very useful, especially during testing phases if you have a built-in bug reporting system.

Your system could directly integrate the logs into the bug report. Don’t forget to ask for user consent through a checkbox, for example:

Report bug in one of my game

Windows

public void SendLog()
{
    // get PlayerLog
    var logPath = Path.Combine(Environment.GetEnvironmentVariable("AppData"), "..", "LocalLow", Application.companyName, Application.productName, "Player.log");

    // get PlayerPrevLog
    var preLogPath = Path.Combine(Environment.GetEnvironmentVariable("AppData"), "..", "LocalLow", Application.companyName, Application.productName, "Player-prev.log");
    
    // read if file exists
    if (File.Exists(logPath))
    {
        string logs = ReadShareFile(logPath);
    }
}

// Logs are shared file we can read it with this function
private string ReadShareFile(string path)
{
    using (var fileStream = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
    using (var textReader = new StreamReader(fileStream))
    {
        return textReader.ReadToEnd();
    }
}

Linux

var pathLinux = CombinePaths("~/.config/unity3d", Application.companyName, Application.productName, "Player.log");

Mac

var pathMac = CombinePaths("~/Library/Logs", Application.companyName, Application.productName, "Player.log");

For Android and iOS, direct log collection is not possible. Native code needs to be used. However, as an alternative, you can subscribe to a log message event and then store them: Application.logMessageReceived.

Or, you can create your own logging system, such as a Logger.
