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 = 800HEIGHT = 600TITLE = "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 = 800SCREEN_HEIGHT = 600SCREEN_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:
