How to show a timer on screen using arcade in Python3?

Prerequisite: Arcade library

Arcade is a modern framework, which is used to make 2D video games. In this, article, you will learn how to show an on-screen timer using the arcade module of Python. Displaying a timer on screen  is not tough job, just follow the below steps:-

Step 1: First of all import the arcade module of Python

Python3

import arcade

Step 2: Define parameters necessary for the output screen.

Python3

WIDTH = 800
HEIGHT = 600
TITLE = "Timer"

Step 3: Define a class MYTimer and under that class, set the background color and starting time.

Python3

class MyTimer(arcade.Window):

    def setup(self):
        arcade.set_background_color(arcade.color.WHITE)
        self.total_time = 0.0

Step 4: Under MyTimer class, define one function to calculate the minutes and seconds.

Python3

def on_draw(self):

    # Start the render.
    arcade.start_render()

    # Calculate minutes
    minutes = int(self.total_time) // 60

    # Calculate seconds by using a modulus
    seconds = int(self.total_time) % 60

    # Figure out your output
    output = f"Time: {minutes:02d}:{seconds:02d}"

    # Output the timer text.
    arcade.draw_text(output, 300, 300, arcade.color.BOTTLE_GREEN, 45)

Step 5: Now, define an on_update function to update time with each increasing minutes and seconds.

Python3

def on_update(self, delta_time):
    self.total_time += delta_time

Step 6: Last and foremost step is to define main() and call it in the end.

Python3

def main():
    window = MyTimer()
    window.setup()
    arcade.run()

main()

Complete code

Python3

#import module
import arcade

# screen parameters
SCREEN_WIDTH = 800
SCREEN_HEIGHT = 600
SCREEN_TITLE = "Timer "

# define class


class MyTimer(arcade.Window):

    def setup(self):
        arcade.set_background_color(arcade.color.WHITE)
        self.total_time = 0.0

    def on_draw(self):

        # Start the render.
        arcade.start_render()

        # Calculate minutes
        minutes = int(self.total_time) // 60

        # Calculate seconds by using a modulus
        seconds = int(self.total_time) % 60

        # Figure out your output
        output = f"Time: {minutes:02d}:{seconds:02d}"

        # Output the timer text.
        arcade.draw_text(output, 300, 300, arcade.color.BOTTLE_GREEN, 45)

    # update
    def on_update(self, delta_time):
        self.total_time += delta_time

# main function
def main():
    window = MyTimer()
    window.setup()
    arcade.run()


# call main function
main()

Output:
