There might be times during development when you need to obtain information from the logs of the standalone player you’ve built, the target device, or the Editor. Usually you need to see these files when you have experienced a problem, to find out exactly where the problem occurred.
On macOS, the player and Editor logs can be accessed uniformly through the standard Console.app utility.
On Windows, the Editor logs are placed in folders which are not shown in the Windows Explorer by default. See below.
To view the Editor log, select Open Editor Log in Unity’s Console window.
| OS | Log files |
|---|---|
| macOS | ~/Library/Logs/Unity/Editor.log |
| Windows XP | C:\Documents and Settings\username\Local Settings\Application Data\Unity\Editor\Editor.log |
| Windows Vista/7 | C:\Users\username\AppData\Local\Unity\Editor\Editor.log |
On macOS, all the logs can be accessed uniformly through the standard Console.app utility.
On Windows, the Editor log file is stored in the local application data folder <LOCALAPPDATA>\Unity\Editor\Editor.log, where <LOCALAPPDATA> is defined by CSIDL_LOCAL_APPDATA.
| OS | Log files |
|---|---|
| macOS | ~/Library/Logs/Unity/Player.log |
| Windows XP | C:\Documents and Settings\username\Local Settings\Application Data\CompanyName\ProductName\output_log.txt |
| Windows Vista/7 | C:\Users\username\AppData\LocalLow\CompanyName\ProductName\output_log.txt |
| Linux | ~/.config/unity3d/CompanyName/ProductName/Player.log |
Note that on Windows and Linux standalones, the location of the log file can be changed (or logging suppressed). See documenttion on Command line arguments for further details.
Access the device log in XCode via the GDB console or the Organizer Console. The latter is useful for getting crashlogs when your application was not running through the XCode debugger.
The Troubleshooting and Reporting crash bugs guides may be useful for you.
Access the device log using the logcat console. Use the adb application found in Android SDK/platform-tools directory with a trailing logcat parameter:
$ adb logcat
Another way to inspect the LogCat is to use the Dalvik Debug Monitor Server (DDMS). DDMS can be started either from Eclipse or from inside the Android SDK/tools. DDMS also provides a number of other debug related tools.
Access the device log using the Smart Devlopment Bridge console. Use the sdb application found in Tizen SDK/tools directory with a trailing dlog parameter:
$ sdb dlog
If you only want to see messages from Unity, you may add a filter. The filter specification is similar to that for Android. The following command only displays messages for the Unity log.
$ sdb dlog Unity:*
| Device | Log files |
|---|---|
| Desktop | %USERPROFILE%\AppData\Local\Packages<productname>\TempState\UnityPlayer.log |
| Windows Phone | Can be retrieved with Windows Phone Power Tools. The Windows Phone IsoStoreSpy can also be helpful. |
On WebGL, log output is written to the browser’s JavaScript console.
On Windows, the log files are stored in locations that are hidden by default. In Windows XP, make hidden folders visible in Windows Explorer using Tools > Folder Options… > View (tab).
On Windows Vista/7, make the AppData folder visible in Windows Explorer using Tools > Folder Options… > View (tab). The Tools menu is hidden by default; press the Alt key once to display it.
