How to stop and continue the program

Jeykay

``Hello, i am from germany and absolutely new to godot. in addition, my english is bad. But i'll try to explain it the best i can.

I have got this simple Code:

extends Node2D

    var a = "This should be printed after the user clicked OK button"
    
    func _ready():
    	var dialog = ConfirmationDialog.new()
    	dialog.dialog_text = "Continue?"
    	dialog.window_title = "Program stopped"
    	dialog.connect('modal_closed', _dialog, 'queue_free')
    	dialog.popup_exclusive = true
    	add_child(_dialog)
    	dialog.popup_centered()
    	print(a)

I think this is an extremely simple problem but i cant find out how to stop the program till the user clicked the OK button in the dialog. Again sorry for my bad pronunciation.

Greetings Jan

See Pausing games in the documentation.

OK, poorly explained. Lets think the dialog hast 2 buttons, yes and no.

How can i take a brake in the code until the user clicked yes or no and react on it? For example:

... ... ... YesNoDialog.popup_centered() if user clicked YesButton: do something else do other thing ... ... ...

as in c#:

if(MessageBox.Show("","",MessageBoxButtons.YesNo) == DialogResult.Yes)
{
   //do something
}

Here's the code I'm using in a similar case. This script is attached to the PopupPanel. $Panel/Ok is a Button. (There's only one button in this case.)

extends PopupPanel

onready var button: Button = $Panel/Ok


func _ready() -> void:
	
	# Make button work while game is paused.
	pause_mode = Node.PAUSE_MODE_PROCESS
	
	popup_exclusive = true

	#warning-ignore:RETURN_VALUE_DISCARDED
	connect("about_to_show", self, "_on_about_to_show")

	#warning-ignore:RETURN_VALUE_DISCARDED
	connect("popup_hide", self, "_on_hide")

	#warning-ignore:RETURN_VALUE_DISCARDED
	button.connect("pressed", self, "_on_pressed")
	

func _on_about_to_show() -> void:
	get_tree().paused = true


func _on_hide() -> void:
	get_tree().paused = false


func _on_pressed() -> void:
	hide()

Uhm, is this that hard in Godot? The reason for my question is that i test if a directory exists and if yes i want to ask to delete or not. How do i do that?

ConfirmationDialog may be closer to what you want, but you'll still have to add some code. https://docs.godotengine.org/en/stable/classes/class_confirmationdialog.html#class-confirmationdialog

You could check the Assets library to see if someone has written an add-on that makes it easier ("More" link at top of page).
