Create pong game using Python – Turtle

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:

Python3

# 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:
