This means that when you attach audio nodes to a scene, the sound is audible through obstacles. For loud gunshots or ambient sounds in a forest, this may be acceptable. But often, gameplay requires you to hide a sound: you do not want all players to hear the zombies right away—not before they have entered the abandoned warehouse and it's too late.

The sample code given next introduces you to a simple case of directional audio.
