This can help +if for example, a texture is being loaded. + +### Log levels + +The logger has five different levels that can be assigned to a message. These are, from lowest to +highest severity, `LogLevel::DEBUG`, `LogLevel::INFO`, `LogLevel::WARNING`, `LogLevel::ERROR` +and `LogLevel::FATAL`. Messages that the developer then wants to write to the logs can take any +of these severities and the developer can then decide what the minimum severity is that the logger +should log. By default, the logger will log anything that is above `LogLevel::INFO`. + +### Using the Logger in your Game + +There are a few preprocessor definitions to make the use of the logger as simple as possible. +First of all, there is a definition to get the instance of the current global logger, which +can then be used to set a different minimum display level. This definition is `yLogger`, and an +example of how to use it to change the default output level can be seen below + +``` c++ +yLogger.setLevel(yage::LogLevel::ERROR); +``` + +The above code changes the global logger so that it will only output things that are an error or +fatal and make the engine crash. + + +Other preprocessor definitions are `yLogDebug`, `yLogInfo`, `yLogWarning`, `yLogError` and +`yLogFatal`. These return an object that is similar to a buffer, but belongs to the main +global logger `yLogger`. These are the definitions that should be used to print somehting +to the main logger. For example + +``` c++ +yLogWarning << "This is a warning"; +``` + +will print the message "This is a warning" with the severity of `LogLevel::WARNING`. + +*/ \ No newline at end of file -- cgit
