AudioListener2D

继承： Node2D < CanvasItem < Node < Object

Overrides the location sounds are heard from.

描述

Once added to the scene tree and enabled using make_current, this node will override the location sounds are heard from. Only one AudioListener2D can be current. Using make_current will disable the previous AudioListener2D.

If there is no active AudioListener2D in the current Viewport, center of the screen will be used as a hearing point for the audio. AudioListener2D needs to be inside SceneTree to function.
