Unigine::Log Class

Header: #include <UnigineLog.h>

This class represents an interface for printing various types of messages to the console and to the log file. It can be useful to monitor overall progress of application execution and report errors which can be helpful in the process of debugging.

Notice
To enable displaying system messages in the Console use the following command: console_onscreen 1

There are two custom color schemes highlighting log syntax for Notepad++ included in the SDK:

  • <SDK>/utils/log_styles/notepad_light.xml
  • <SDK>/utils/log_styles/notepad_dark.xml

Example#

The following code demonstrates how to print various types of messages.

Source code (C++)
using namespace Unigine;

// auxiliary variables for messages
char *file_name = "file.txt";
int ID = 10;
	
// reporting an error message
Log::error("Loading mesh: can't open \"%s\" file\n", file_name);

// reporting a message
Log::message("-> Added %d UI elements.\n", 10);
	
// reporting a warning message
Log::warning("ID of the \"%s\" file: %d.\n", file_name, ID);
	
// reporting a fatal error message to the log file and closing the application
Log::fatal("FATAL ERROR reading \"%s\" file!\n", file_name);
