Exploring directional sound in 2D

In this recipe, we will attach AudioStreamPlayer2D to a block and create a player. When the player moves toward the block, the sound file will play and get louder as the player gets closer.

Getting ready

For this recipe, open Godot 4 and start a new project called Chapter 7. In the Scene tab, click 2D to add a 2D scene. Click on Scene in the main menu next to Project, then select Save Scene As, and name the scene Audio2D.

How to do it…

We start by creating the background, the box with the AudioStreamPlayer2D node, and the player:

1. Left-click on the Node2D node and then + in the Scene tab. In the Create New Node window, type mesh in the Search box and then select MeshInstance2D to create the node in the Scene tab. Left-click the Create button.
2. Right-click the MeshInstance2D node in the Scene tab and rename it Background.
3. In the Inspector window, click on <empty> to the right of Mesh and select New BoxMesh.
