My first question

Hello everyone, I've been trying to crack into godot and I coded some basic buttons labels and timers, trying to make a basic game. I've connected a timer to start on button click and now i want to display a "cooldown" on the button, set its text to the time remaining of the timer and disable the button. I cannot figure out how to use fixed_process and set_fixed_process to sort of initiate the loop.

func _pressed():
	var a = get_parent().get_node("tajmer")
	var b = get_parent().get_node("tajmerkopce")
	b.set_disabled(true)
	a.start()
	b.set_text(str(a.get_wait_time()))
	set_fixed_process(true)
	pass
# class member variables go here, for example:
# var a = 2
# var b = "textvar"

func _fixed_process():
	var a = get_parent().get_node("tajmer")
	var b = get_parent().get_node("tajmerkopce")
	if a.get_wait_time() > 0:
		b.set_text(str(a.get_wait_time()))
	pass

Not sure if this is how you do it but any help would be nice. Thanks :smile:

Hi,..first I must say that I'm a beginner in programming in GDscript and programming at all.... but I would write this variables elsewhere - not need to write them two times put them on the start of the script to other variables onready var a = get_parent().get_node("tajmer") ........ not use pass in the end function also I think is better or needed use func process(delta): ...fixed is for a synchronization with the physics engine...when you use physics then use fixed delta time process....I think. ....another thing is that in the func fixed_process(): is missing variable delta like func _fixed_process(delta): ....maybe i helped a little :)

Delta time - updating scenery based on the elapsed time since the game last updated (i.e. the previous "frame") which will vary depending on the speed of the computer.This also allows graphics to be calculated separately if graphics are being multi-threaded. In graphics programming, this avoids the gameplay slowing down or speeding up depending on the complexity of what is happening at any given time, which would make for an inconsistent, jarring experience (e.g. time slowing down the more characters walk onto the screen, or running too fast because only one character is on screen). (taken from Wikipedia Delta timing ) ....also look at Questions & Answers forum - godotengine.org/qa/

Hi :) Thanks for your reply Haha yea you maybe helped a little. I don't get what delta is tbh.

I just want a button to change its text according to the remaining wait time of a timer. So far I found it working through code, so you can probably loop it. I tried and failed so far and decided to try get some help :dizzy:

How would you loop a button and change its text? its also disabled while timer lasts and becomes active afterwards

I'd probably just go with a timer node connected with timeout(), but if you want to do it in just one script you can: - Create a cooldown variable and set it to zero; - When the button is pressed, disable the button; - In process(delta) check if the button is disabled (you can use button.is_disabled()). If it is, add delta to cooldown; - Check if cooldown is greater than or equal to your value (the button cooldown time). If it is, "un-disable" the button and set the cooldown variable to 0;

E.g.:

extends Node

const COOLDOWN_TIME = 3.0

onready var button = get_node("button_path")

var _cooldown time = 0.0

func _process(delta):
	if button.is_disabled():
		_cooldown_time += delta
	if _cooldown_time >= COOLDOWN_TIME:
		button.set_disabled(false)
		_cooldown_time = 0.0

func _on_button_pressed():
	button.set_disabled(true)

(By the way, what is the code tag?)
