Unity produces log files for the Editor, package manager, and development players. You can use these log files to understand where any problems happened in your application.
Unity adds all messages, warnings, and errors from the Console window to the log files. To add your own messages to the Console window, and the logs, use the Debug class.
Each operating system stores the log files in different locations. The default locations are outlined on this page, but you can also use certain command line arguments to control when and where Unity generates log files. For more information, see the Command line arguments documentation.
You can access the Editor logs from the console window. To do this, open a Console Window (menu: Window > General > Console) and select Open Editor Log from the Console window menu.
| Log type | Log location |
|---|---|
| Editor | ~/.config/unity3d/Editor.log |
| Package manager | ~/.config/unity3d/upm.log |
On macOS, you can also access Unity’s logs via the Console.app utility
| Log type | Log location |
|---|---|
| Editor | ~/Library/Logs/Unity/Editor.log |
| Package manager | ~/Library/Logs/Unity/upm.log |
On Windows, the Package Manager and Editor logs are placed in folders which aren’t shown in the Windows Explorer by default. To view the AppData folder, you must enable the Hidden Items setting on Windows. For more information on how to do this, see Microsoft’s documentation on View hidden files and folders in Windows.
On Windows, a standard out stream doesn’t exist by default, so you must launch the Editor with a valid configured stdout stream, as a child process from a CI system. If you specify - to send output` tostdout`, then you won’t see the output in the console window.
| Log type | Log location |
|---|---|
| Editor | %LOCALAPPDATA%\Unity\Editor\Editor.log |
| Package manager | User account: %LOCALAPPDATA%\Unity\Editor\upm.log SYSTEM account: %ALLUSERSPROFILE%\Unity\Editor\upm.log
|
| Crash files |
%TMP%\CompanyName\ProductName\Crashes Note: You can overwrite the location of the folder location with the -crash-report-folder command line argument. |
To view the Player log, open a Console Window (menu: Window > General > Console) and select Open Player Log from the Console window menu. You can also navigate to the following folder:
| 操作系统 | Player log location |
|---|---|
| Android | Use Android debug bridge (adb) to access your device log. To use it, launch the adb application in the Android SDK/platform-tools directory with the logcat parameter:$ adb logcatFor more information, see Android’s documentation on logcat. You can also use Unity’s Logcat package which adds an interface to the Editor to get logs from Android. |
| iOS | Use the GDB console, or the Organizer Console through XCode to access iOS device logs. For more information on device logs, see Apple’s documentation. |
| Linux | ~/.config/unity3d/CompanyName/ProductName/Player.log |
| macOS |
~/Library/Logs/Company Name/Product Name/Player.logNote: You can also use the Console.app utility to find the log file. |
| 通用 Windows 平台 | %USERPROFILE%\AppData\Local\Packages\<productname>\TempState\UnityPlayer.log |
| WebGL | Unity writes the log output to your browser’s JavaScript console. |
| Windows | %USERPROFILE%\AppData\LocalLow\CompanyName\ProductName\Player.log |
