I have some problems with controlling music in the game options and can’t find way out. it works normal until player click the button ‘+’ or ‘-’
Maybe i do something wrong?

 extends Button
func _pressed():
	var node = get_node("Control/music/Slider")
	if(name == "minus"):
		node.set_value(node.get_value() - node.step)
		node.set_value(node.get_value() + node.step)
	var dbVolue = node.value
	AudioServer.set_bus_volume_db(AudioServer.get_bus_index(get_node("Control/music").name), dbVolue)

That is telling you that node is a "null instance. That means that get_node("Control/music/Slider") is not a returning a valid node, probably because the node path is incorrect.

You need to use the correct path from this Button node to the “Slider” node. I can’t tell you what that is because I can’t see your scene tree.

See here for an explanation of node paths:
