Audio Manager


You’ve tried adding an AudioStreamPlayer to your mob/coin/etc. to play when the object dies or is collected. But the problem is that when you remove the object, the audio player goes with it, chopping off the sound. You need an easier way to manage playing audio.


We’ll solve this problem with a node that is available from anywhere in the SceneTree. This node manages a set of AudioStreamPlayer nodes and a queue of sound streams to play.

Create a new script in the script editor.

extends Node

var num_players = 8
var bus = "master"

var available = []  # The available players.
var queue = []  # The queue of sounds to play.

func _ready():
    # Create the pool of AudioStreamPlayer nodes.
    for i in num_players:
        var p =
        p.connect("finished", self, "_on_stream_finished", [p])
        p.bus = bus

func _on_stream_finished(stream):
    # When finished playing a stream, make the player available again.

func play(sound_path):

func _process(delta):
	# Play a queued sound if any players are available.
    if not queue.empty() and not available.empty():
        available[0].stream = load(queue.pop_front())

Set this script as an autoload in Project Settings. Give it an easily recognizable name, such as “AudioStreamManager”.

Anywhere in your project that you want to play a sound, use:"res://path/to/sound")
