Learn with Hafiza Palwasha

How to design a game 'Basic Ping Pong' Using Visual Studio and Python (Free) ?

Lecture No. 5

1. Download visual studio 'Visual Studio', from the link as shown below and install it.

2. Now download 'Python', from the link as shown below and install it.

3. Go to the 'Downloads' and download 'Python install manager' as shown below:

4. Now run the python, a block window will appear, keep typing 'y' to install and connection with the visual studio.

5. Next, open the visual studio and install updates.

6. Now paste the below code and run it with the play button at the top right side.

import turtle

# Create the screen

wn = turtle.Screen()

wn.title("Ping Pong Game")

wn.bgcolor("black")

wn.setup(width=800, height=600)

wn.tracer(0)

# Paddle A (Left)

paddle_a = turtle.Turtle()

paddle_a.speed(0)

paddle_a.shape("square")

paddle_a.color("white")

paddle_a.shapesize(stretch_wid=5, stretch_len=1)

paddle_a.penup()

paddle_a.goto(-350, 0)

# Paddle B (Right)

paddle_b = turtle.Turtle()

paddle_b.speed(0)

paddle_b.shape("square")

paddle_b.color("white")

paddle_b.shapesize(stretch_wid=5, stretch_len=1)

paddle_b.penup()

paddle_b.goto(350, 0)

# Ball

ball = turtle.Turtle()

ball.speed(0)

ball.shape("circle")

ball.color("white")

ball.penup()

ball.goto(0, 0)

ball.dx = 0.2  # Speed in x direction

ball.dy = 0.2  # Speed in y direction

# Functions to move paddles

def paddle_a_up():

    y = paddle_a.ycor()

    y += 20

    paddle_a.sety(y)

def paddle_a_down():

    y = paddle_a.ycor()

    y -= 20

    paddle_a.sety(y)

def paddle_b_up():

    y = paddle_b.ycor()

    y += 20

    paddle_b.sety(y)

def paddle_b_down():

    y = paddle_b.ycor()

    y -= 20

    paddle_b.sety(y)

# Keyboard bindings

wn.listen()

wn.onkeypress(paddle_a_up, "w")

wn.onkeypress(paddle_a_down, "s")

wn.onkeypress(paddle_b_up, "Up")

wn.onkeypress(paddle_b_down, "Down")

# Main game loop

while True:

    wn.update()

    # Move the ball

    ball.setx(ball.xcor() + ball.dx)

    ball.sety(ball.ycor() + ball.dy)

    # Border checking (Top/Bottom)

    if ball.ycor() > 290:

        ball.sety(290)

        ball.dy *= -1

   

    if ball.ycor() < -290:

        ball.sety(-290)

        ball.dy *= -1

    # Border checking (Left/Right) - Reset ball if it passes paddle

    if ball.xcor() > 390:

        ball.goto(0, 0)

        ball.dx *= -1

       

    if ball.xcor() < -390:

        ball.goto(0, 0)

        ball.dx *= -1

    # Paddle and ball collisions

    if (ball.xcor() > 340 and ball.xcor() < 350) and (ball.ycor() < paddle_b.ycor() + 40 and ball.ycor() > paddle_b.ycor() - 40):

        ball.setx(340)

        ball.dx *= -1

    if (ball.xcor() < -340 and ball.xcor() > -350) and (ball.ycor() < paddle_a.ycor() + 40 and ball.ycor() > paddle_a.ycor() - 40):

        ball.setx(-340)

        ball.dx *= -1

Homework Task

Now you have to do the following tasks to show your skills:

1. Change the shape of ball to square.

2. Move the turtle top and bottom instead of left and right, and the ball movement should be accordingly.

3. Make the background 'white' and turtle and ball color 'black'.
