Playing Audio Files
You can play long background music or short sound effects by using the audio system for example:
Will play a long background file called “melody2”
Will play a short explosion sound effect.
If you want your background music to play in a loop, just add the “loop” attribute to the audio.play command:
audio.play "melody2" loop
Note: there is no need to add the async attribute to the audio.play is a non-blocking command
