Question

So right now in my game I'd like to add sound effects whenever i press hover or select a UI node, the obvious solution is to simply make a class out of the base button or UI element class and use those as the foundation
but i was wondering if i can have an Auto-load that detect whenever a button is pressed or any UI element received a specific event and then play the sound itself, sort of, high-jacking the signal if that makes sense

Implement a signal handler in an autoload that connects to SceneTree’s node_added signal. There you can check the type of the added node and connect to any of its signals you want to handle.

have a autoload like this:

extends Node

var playback:AudioStreamPlaybackPolyphonic

const CLICK = preload("res://audio/click/click.wav")
const HOVER = preload("res://audio/click/hover.wav")

func _enter_tree() -> void:
	var player = AudioStreamPlayer.new()
	add_child(player)
	
	var stream = AudioStreamPolyphonic.new()
	stream.polyphony = 32
	player.stream = stream
	player.play()
	playback = player.get_stream_playback()
	
	get_tree().node_added.connect(_on_node_added)


func _on_node_added(node:Node) -> void:
	if node is Button:
		node.mouse_entered.connect(_play_hover)
		node.pressed.connect(_play_pressed)

func _play_hover() -> void:
	playback.play_stream(HOVER, 0, 0, randf_range(0.9, 1.1))
	
	
func _play_pressed() -> void:
	playback.play_stream(CLICK, 0, 0, randf_range(0.9, 1.1))

exactly what i need thank you man!
also don’t i need to free all the nodes connected when the level changes?

i didn’t know there was a node_added method so that’s good to know

sorry for the late, i dont think you have to worry about freeing when changing scenes :thinking:
