3D Coordinate System of 3D Audio

This is the cartesian coordinate system that the 3d audio of the game uses.

X is the axis for left and right. Positive x is right.

Y is the axis for up and down. Positive y is up.

Z is the axis for forward and back. Positive z is back.

Since the game is in isometric 2d, the 3D sound needs to be translated in a way that makes sense with an isometric 2d visual view. The view that seems to best translate 3D audio into an isometric 2D view is that the player is looking at the isometric 2d world as if from above. 3D audio X axis is the horizontal axis of the world. Z axis is the vertical axis of the world. Y axis is an imaginary "height" axis that gives the impression that sounds coming from the hills are closer to the player since the player is above the world.
