Updates for r16332, mentions wx* functions for Atlas

This page documents some ways of logging and outputting text in the game, both within the engine and scripts. This is useful to know for debugging and when the user should be notified of something.

Engine

The coding conventions have some information regarding logging in the engine.

The engine is written in C++. Prefer the following functions for logging and outputting text:

  • LOGMESSAGE(const char* format, ...)
  • LOGMESSAGERENDER(const char* format, ...)

Use these functions to report possible misconfigurations or errors that can be caused by modding:

  • LOGWARNING(const char* format, ...)
  • LOGERROR(const char* format, ...)
  • debug_printf(const char* format, ...)
Function Game console Rendered message Main log Interesting log stdout* stderr
LOGMESSAGE N N Y N N N
LOGMESSAGERENDER Y Y - green text Y N N N
LOGWARNING Y Y - yellow text Y Y Y N
LOGERROR Y Y - red text Y Y Y N
debug_printf N N N N Y N

* On Windows, the game writes debug output instead of stdout. Run the game in a debugger or use DebugView to view it.

Note: to use the LOG* functions, you must include ps/CLogger.h.

Scripts

The game's scripts are written in JavaScript, but they won't necessarily have the same functions available as in a web browser. Use these functions for outputting text:

  • print(message)
  • console.write(message)
  • log(message)
  • warn(message)
  • error(message)
Function Game console Rendered message Main log Interesting log stdout* stderr
print N N N N Y N
console.write Y N N N N N
log N N Y N N N
warn Y Y - yellow text Y Y Y N
error Y Y - red text Y Y Y N

* On Windows, the game writes debug output instead of stdout. Run the game in a debugger or use DebugView to view it.

Atlas UI

In Atlas UI, wxWidgets provides several logging functions.

  • wxLogDebug(const char* formatString, ...) - Logs to terminal/debug output only.

Note: by default, the following functions only display a message box to the user:

  • wxLogMessage(const char* formatString, ...)
  • wxLogWarning(const char* formatString, ...)
  • wxLogError(const char* formatString, ...)
