Logging

The engine has built-in logger that allows you to trace execution of your game by creating log entries when needed.

The window allows you to select severity of the messages that will be put in the window:

• Info+ will show all messages with Info, Warning, Error severities.
• Warning+ will show all messages with Warning and Error severities.
• Error will show all messages with only Error severity.

Each log entry can be copied to the clipboard by right-clicking on it and pressing Copy in the context menu. You can also clear the log using Clear button.

Writing to the log

You can use one of Log::info, Log::warn, Log::err methods, or use Log::writeln with severity specified. It is also possible to select desired severity level:

#![allow(unused)]
fn main() {
extern crate fyrox;
use fyrox::core::log::{Log, MessageKind};
// These lines will be printed.
Log::info("This is some info");
Log::warn("This is some warning");
Log::err("This is some error");

Log::set_verbosity(MessageKind::Warning);

Log::info("This is some info"); // This won't be printed.
Log::warn("This is some warning");
Log::err("This is some error");
}
