How can I display the remaining time from a countdown timer on a label in Godot?

Displaying Countdown Timer on a Label in Godot

Overview

In Godot, displaying the remaining time from a countdown timer on a label involves using the built-in Timer node to track elapsed time and a Label node to show the timer countdown. This requires both script editing to handle time calculations as well as UI updates.

Step-by-Step Implementation

1. Setting up Nodes

Add a Timer node to your scene.
Set the Wait Time property of the Timer node to your desired countdown duration and ensure the One Shot property is enabled.
Add a Label node to your scene where you want to display the countdown.

2. Scripting the Timer

Attach a GDScript to a parent node or directly to the Timer node and initialize required variables:

Test your luck right now!

extends Node

var timer_started = false
var time_left = 10 # The initial countdown time in seconds

onready var label = $Label # Path to your Label node

3. Handle Timer Signals

Connect the Timer’s timeout() signal to the script to handle the end of the countdown and update the label every frame:

func _ready():
    $Timer.connect("timeout", self, "_on_Timer_timeout")
    $Timer.start()
    timer_started = true

func _process(delta):
    if timer_started:
        time_left = max(0, time_left - delta) # Reducing time left each frame
        label.text = "Time Left: " + str(round(time_left)) # Updating the label in real-time

4. Handling Timeout

Create a function to manage the actions when the timer ends:

func _on_Timer_timeout():
    timer_started = false
    label.text = "Time's up!"

Additional Considerations

Ensure that the Timer and Label paths in your script match the actual node paths in your scene.
Adjust the Timer and UI settings as needed to fit the game design requirements.
Consider exploring more advanced UI styling and animations to enhance the player experience.
