How to Draw Rectangles in Pygame

In this Pygame article we want to learn How to Draw Rectangles in Pygame, if you are creating a game or any other kind of interactive program with Pygame, some times you will need to draw rectangles. Rectangles are useful for creating game objects, UI elements and much more. in this article we want to talk that how to draw rectangles using pygame.draw.rect() function.

First if all you need to import Pygame module and initialize it with pygame.init() function.

import pygame
pygame.init()

1 2	import pygame pygame.init()

So before you draw a rectangle, you need to set dimensions of the Pygame display. you can do this using pygame.display.set_mode() function.

display_width = 800
display_height = 600
game_display = pygame.display.set_mode((display_width, display_height))

display_width = 800

display_height = 600

game_display = pygame.display.set_mode((display_width, display_height))

Now we are ready to draw rectangle, pygame.draw.rect() function takes several arguments, including display surface to draw on, color of the rectangle, position of the top left corner of rectangle and dimensions of the rectangle. this is an example of how to draw a rectangle:

# Draw red rectangle at (100, 100) with a 
# width of 50 and a height of 100
pygame.draw.rect(game_display, (255, 0, 0), (100, 100, 50, 100))

# Draw red rectangle at (100, 100) with a

# width of 50 and a height of 100

pygame.draw.rect(game_display, (255, 0, 0), (100, 100, 50, 100))

After drawing a rectangle, you need to update Pygame display for the changes to take effect. you can do this with pygame.display.update() function.

pygame.display.update()

1	pygame.display.update()

This is the complete code for this article

import pygame

pygame.init()

# Set dimensions of the display window
display_width = 800
display_height = 600
game_display = pygame.display.set_mode((display_width, display_height))

# Draw red rectangle at (100, 100)
# with a width of 50 and height of 100
pygame.draw.rect(game_display, (255, 0, 0), (100, 100, 50, 100))

# Updat display
pygame.display.update()

# Game loop
game_exit = False
while not game_exit:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_exit = True

    # Your game code here

    # Update  display
    pygame.display.update()

# Quit Pygame
pygame.quit()
quit()

import pygame

pygame.init()

# Set dimensions of the display window

display_width = 800

display_height = 600

game_display = pygame.display.set_mode((display_width, display_height))

# Draw red rectangle at (100, 100)

# with a width of 50 and height of 100

pygame.draw.rect(game_display, (255, 0, 0), (100, 100, 50, 100))

# Updat display

pygame.display.update()

# Game loop

game_exit = False

while not game_exit:

for event in pygame.event.get():

if event.type == pygame.QUIT:

game_exit = True

# Your game code here

# Update display

pygame.display.update()

# Quit Pygame

pygame.quit()

quit()

This code initializes Pygame and sets dimensions of the display window. after that it draws red rectangle using pygame.draw.rect(). and finally this code enters a game loop that continually updates the display until the user closes the window.

Run the complete code and this will be the result

So we can say that Drawing rectangles is an important part of creating games and interactive programs. by using pygame.draw.rect() function you can easily draw rectangles of any size and color. just remember to update the display for the changes to take effect.
