`extends Panel

var butt1 = “Nope!”
var butt2 = “Wrong!”
var butt3 = “Not It!”
var butt4 = “Winner Winner Chicken Dinner!”

func _ready():
for button in get_tree().get_nodes_in_group(“Buttons”):
button.connect(“pressed”, self, “_on_button_pressed”, [button])

func _some_button_pressed(button):

func _on_Button_pressed():
get_node(“Label”).text = “Nope!”

func _on_Button2_pressed():
get_node(“Label”).text = “Wrong!”

func _on_Button3_pressed():
get_node(“Label”).text = “Not It!”

func _on_Button4_pressed():
get_node(“Label”).text = “Winner Winner Chicken Dinner!”`

So I have multiple buttons and want a different result depending on what button is pressed but I am having a heck of a time figuring out how to put that into my _some_button_pressed() function. I know I have to be missing something obvious but I am not seeing it. Thanks and sorry for the N00b question.

The easiest way is to create a dictionary, you can also use a match statement or a series of if elifs:

extends GridContainer

var button_functions : Dictionary
	
func _ready():
	var button1 = Button.new()
	var button2 = Button.new()
	
	button_functions = {button1 : "do_something_cool",
						button2 : "do_something"}
										
	for button in button_functions.keys():
		self.add_child(button)
		button.text = button_functions.get(button)
		button.connect("pressed", self, "some_button_pressed", [button])

func some_button_pressed(button):
	var function_to_call = button_functions.get(button)
	if function_to_call:
		call(function_to_call)
		
func do_something_cool():
	print("cool")
	
func do_something():
	print("something")

Here I am using a dictionary with the keys being the buttons pressed that maps those buttons to which function they should call.

Note that I switched the node type from a Panel to a GridContainer because it doesn’t make much sense to store buttons in a Panel, they should be stored in some kind of a Container node.

I am creating the buttons through code here but you can just as easily do:
onready var button1 = get_node("path/to/my/button1") above the _ready() function.

You are connecting the signals well but declaring the receiving method wrongly.
Declare it as : on_button_pressed(button):
so that it can receive the pressed button.

To set different text depending on the pressed button, type:

if button.name == "button_name":
    $"Label".text = "text for that button"

Then get rid of the other methods, you only need one.
Hopefully this helps.
