time delay for action on buttons

Hi folks, I am trying to make my buttons jiggle after being pressed, and then after like 2 seconds then it would change the scene. What I am struggling with is what I think is the lack of a native time function. So I created a timer function as a global (since I would like to reuse the delay code in many buttons etc) but I am having an issue in which the timer code doesn’t trigger the chance scene code. If I place the timer contents directly into the button it works but if I try to make it a function that is hosted globally it doesnt. The function does get triggered but it does not call the action for the timer.

in global snippets:

extends Node
func _delay(delay,action):
	print("delay triggered")
	var timer = Timer.new()
	timer.connect("timeout", self, action)
	return timer.start()

In button pressed:

func _switch_delay():
func _on_jumble_play_button_pressed():

	self.rect_scale.x = 0.2 + deg2rad(sin(2*time + 1))/2
	self.rect_scale.y = 0.2 + deg2rad(sin(2*time + 1))/2
	self.rect_position.x = start_x + ((self.rect_size.x * 0.2) - (self.rect_size.x * self.rect_scale.x))/2
	self.rect_position.y = start_y + ((self.rect_size.y * 0.2) - (self.rect_size.y * self.rect_scale.y))/2
	self.rect_rotation = 0 + deg2rad(sin(10*time + 15))

You have connected the timers timeout to a function called action but you have a function called _switch_delay to change the scene.

have you tried changing this line

timer.connect("timeout", self, action)


timer.connect("timeout", self, "_switch_delay")

action is a placeholder which is calling _switch_dalay. See the last line of code:

Okay in that case you need to change that line of code too

that doesnt get triggered still

I think the issue is that I am referring to self but I don’t know how to refer to the original button object that was pressed here rather than the timer. in this line:

timer.connect("timeout", self, action)

No self in this instance is telling the timer that when it gets the first signal timeout to do something. The second action signal is what it is supposed to do.

I rather suspect you are not including the quotation marks to make it a string or else you are putting () in with the call. Did you copy my line exactly? I have done exactly this many times and it always worked for me.

You could try the below; making it an autostart rather than just starting it manually.

var timer = Timer.new()
timer.autostart = true
timer.connect("timeout", self, action)

Also is snippets a separate script?

Gluon | 2022-01-10 14:24

yes, snippets is a separate script. It’s a global one. The idea is that I will use the time delay function for other buttons and scenarios. So rather than adding the code directly in each item I use it in (which is working correctly), I would instead call the code in snippets and pass the relevant details needed (hence the doubt about self).
I didn’t add the autostart as I wanted the logic to be called specifically after pressing the button rather than when the object is rendered.

Hello fungain,

as Gluon already mentioned you should use the function name for connect and not the function it self

<source_node>.connect(<signal_name>, <target_node>, <target_function_name>)

Also instead of creating your own logik, I think you could try to use an animation for your button jiggle and trigger the scene change on animation_finished.
