Drawing Shapes and Images in Pygame

This beginner-friendly tutorial walks you through drawing shapes like rectangles and circles, and loading image files into your Pygame projects.

Setting Up Your Pygame Window

Start by importing Pygame and setting up your screen:

import pygame
pygame.init()
screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption("Drawing Shapes and Images")

Drawing Basic Shapes

Pygame makes it easy to draw basic shapes using built-in functions:

# Draw a red rectangle
pygame.draw.rect(screen, (255, 0, 0), (100, 100, 200, 150))

# Draw a blue circle
pygame.draw.circle(screen, (0, 0, 255), (400, 300), 75)

# Draw a green line
pygame.draw.line(screen, (0, 255, 0), (0, 0), (800, 600), 5)

Loading and Displaying an Image

You can load and show image files using the `blit()` method:

# Load the image (make sure 'image.png' is in the same folder)
image = pygame.image.load('image.png')

# Display the image at position (300, 200)
screen.blit(image, (300, 200))

Make sure your image is a supported format like `.png`, `.jpg`, or `.bmp`.

Putting It All Together

Here’s how a complete loop with shapes and images might look:

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

    screen.fill((255, 255, 255))  # White background
    pygame.draw.rect(screen, (255, 0, 0), (100, 100, 200, 150))
    pygame.draw.circle(screen, (0, 0, 255), (400, 300), 75)
    pygame.draw.line(screen, (0, 255, 0), (0, 0), (800, 600), 5)
    screen.blit(image, (300, 200))
    pygame.display.flip()

pygame.quit()

Conclusion

Learning how to draw shapes and render images in Pygame gives you full control over 2D graphics. These basics are essential for building custom interfaces, characters, and levels in your games.
