Lesson 13: Installing Pygame and Drawing Windows

Topics Covered:

• What is Pygame?
• Installing Pygame
• Creating a game window
• Drawing basic shapes: rectangles and circles

What is Pygame?

Pygame is a Python library designed for making video games. It helps you create graphics, play sounds, and handle user input.

Installing Pygame

To install Pygame, open your command prompt or terminal and type:

pip install pygame

If you are using an online editor, check if Pygame is pre-installed or supported.

Creating a Basic Game Window

import pygame
import sys

pygame.init()

# Set up the window
width, height = 640, 480
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("My First Pygame Window")

# Main loop
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    screen.fill((0, 0, 0))  # Fill screen with black
    pygame.display.flip()   # Update the display

pygame.quit()
sys.exit()

Drawing Shapes

You can draw shapes using Pygame’s drawing functions:

# Draw a red rectangle
pygame.draw.rect(screen, (255, 0, 0), (50, 50, 100, 50))

# Draw a blue circle
pygame.draw.circle(screen, (0, 0, 255), (320, 240), 40)

Activity: Draw Your Shapes

Modify the example to draw different colored shapes in different positions and sizes.
