Question

For more context In my game I am checking whether or not you are in the main screen, settings, or game. depending on this different music will play. Problem is I have to check for that constantly and that means it plays constantly. Can somebody help me create a better version?

You can just change the music whenever the player changes the screen they are on.

send a signal to your “core” or main game controller to play a certain bgm when switching to those scenes. no need to check it every frame

Do you mind showing a example. I’m not sure what you mean

By the way I have my sounds played on a Autoload script so that it can play through multiple scenes but I’m Having trouble stopping it. And because its not part of the actual scene I can’t just look up the audio streamer and stop it.

I don’t see why you can’t address an autoload. If you have an autoloded script that’s called, say, my_audio_player, you can totally target it with something like MyAudioPlayer.play() from any node in the tree, that ease of access is kinda one of the points of having a singleton. And if for some reason your game doesn’t recognize that name, you can always explicitly write “class_name MyAudioPlayer” (right before “extends…”) With that, you can get rid of constant checks and just tell the autoload to change music whenever the player enters another screen.

Thanks so much! I’m new to godot so I’m still learning the engine so that’s a big help

main_menu.gd

func _ready():
	...
	await get_tree().create_timer(0.5).timeout
	EventBus.emit_signal("play_bgm", main_menu_bgm)

audio_manager.gd

@export var bgm_player: AudioStreamPlayer2D

func _ready():
	EventBus.play_bgm.connect(play_bgm)

func play_bgm(bgm_file: AudioStream):
	...
	
	if (bgm_player.stream != bgm_file):
		bgm_player.stream = bgm_file
		bgm_player.play()
		
		...

EventBus.gd (autoload script)

signal play_bgm(bgm_file: AudioStream)

something like this to play a bgm with signal, this one send signal directly to audio manager which here is not an autoload, but a pre-deployed scene on a Core scene tree with a child of AudioStreamPlayer2D

to stop playing the bgm when switching scene tho, you also need to send the signal

EventBus.gd (autoload script)
signal stop_bgm

core.gd

func switch_scene(scene_path: String,level=-1):
	var current_scenes = scene_node_container.get_children()
	var scene_count: int = current_scenes.size()
	
	if (scene_count > 0):
		...
		EventBus.emit_signal("stop_bgm")

audio_manager.gd

func stop_bgm():
	bgm_player.stop()

Now I’m having trouble getting it. I tried getting it by doing Sounds.MainMenuMusic (As my audio streamer is MainMenuMusic and the auto load file is Sounds) but its not working. What did I do wrong?

10

Never mind I found out how.

11

Never mind it doesn’t work anymore. I have a variable for music and if its turned of and on again then the music only plays after the main scene is opened again. How do I fix this?

12

which approach you use for this again? the Sounds autoload? or the one i shared with pre-deployed AudioStreamPlayer2D that wont be gone when switch scene?

13

Autoload. Btw I fixed it but the solution is super complicated so I’m up for anything else

14

I basically made a variable to say if the music was false it would make the variable 1 and if it was 1 and music was turned on then it becomes 2. If it was 2 music would play and if it was previously in the arena then it becomes a 0 and the music plays. That’s somewhat of how it works but its really wrong
