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()
