CryLog Logging Functionality

You can log in Lumberyard by using the following global functions.

  • CryLog (eMessage)

  • CryLogAlways (eAlways)

  • CryError (eError)

  • CryWarning (eWarning)

  • CryComment (eComment)

If more control is required, the ILog interface can be used directly by using the following syntax.

gEnv->pLog->LogToFile("value %d",iVal);

Verbosity Level and Coloring

You can control the verbosity of logging with the console variables log_Verbosity and log_FileVerbosity.

The following table shows the levels of verbosity and color convention. In the console, warnings appear in yellow, and errors appear in red.

Message verbosity 0 verbosity 1 verbosity 2 verbosity 3 verbosity 4 Color in console
eAlways X X X X X
eErrorAlways X X X X X red
eWarningAlways X X X X X yellow
eInput ? ? ? ? ?
eInputResponse ? ? ? ? ?
eError X X X X red
eWarning - - X X X yellow
eMessage - - X X
eComment - - - - X


  • X – the message type is logged to the console or file

  • ? – some special logic is involved


Full logging (to console and file) can be enabled by using log_Verbosity 4.
