Create pong game using Python - Turtle

Last Updated : 04 Sep, 2024

Pong is one of the most famous arcade games, simulating table tennis. Each player controls a paddle in the game by dragging it vertically across the screen's left or right side. Players use their paddles to strike back and forth on the ball. Turtle is an inbuilt graphic module in Python. It uses a panel and pen to depict illustrations.

Below are the steps used:

Step 1) Create two paddles A and B on the left and right side of the screen.
Step 2) Create a ball.
Step 3) Create an event to move the paddle vertically on pressing a certain key.
Step 4) Create the function to update the score after each player misses a collision.

Below is the program to create Paddle and Ball:

Python

# Import required library import turtle # Create screen sc = turtle.Screen() sc.title("Pong game") sc.bgcolor("white") sc.setup(width=1000, height=600) # Left paddle left_pad = turtle.Turtle() left_pad.speed(0) left_pad.shape("square") left_pad.color("black") left_pad.shapesize(stretch_wid=6, stretch_len=2) left_pad.penup() left_pad.goto(-400, 0) # Right paddle right_pad = turtle.Turtle() right_pad.speed(0) right_pad.shape("square") right_pad.color("black") right_pad.shapesize(stretch_wid=6, stretch_len=2) right_pad.penup() right_pad.goto(400, 0) # Ball of circle shape hit_ball = turtle.Turtle() hit_ball.speed(40) hit_ball.shape("circle") hit_ball.color("blue") hit_ball.penup() hit_ball.goto(0, 0) hit_ball.dx = 5 hit_ball.dy = -5

Output:

Below is the complete python program to create pong game using turtle library.

Python
