Thread: My Audio System :)

Code:

}

Code:

package com.adventurequest.io.sound;

public class AudioExtension
{

	public static final String MIDI = ".mid";
	
	public static final String MP3 = ".mp3";
}

Pretty simple to use it works fine on my 2D game (currently supports Midi Files only) i will add volume support and mp3 support later on I'm still progressing on this
