How to Draw a Rectangle in Pygame?

Drawing Rectangles in Pygame

In game development, drawing rectangles is a fundamental skill. In Python, using the Pygame library, drawing rectangles is made straightforward.

Solution

To draw a rectangle in Pygame (3.2), follow these steps:

1. Import the necessary Pygame modules:

<code class="python">import pygame, sys
from pygame.locals import *</code>

2. Initialize Pygame:

<code class="python">pygame.init()</code>

3. Create a display surface to draw the rectangle on:

<code class="python">DISPLAY = pygame.display.set_mode((500, 400), 0, 32)</code>

4. Define the colors you want to use:

<code class="python">WHITE = (255, 255, 255)
BLUE = (0, 0, 255)</code>

5. Fill the display surface with a background color:

<code class="python">DISPLAY.fill(WHITE)</code>

6. Use the pygame.draw.rect function to draw the rectangle:

<code class="python">pygame.draw.rect(DISPLAY, BLUE, (200, 150, 100, 50))</code>

7. Display the updated surface:

<code class="python">pygame.display.update()</code>

The pygame.draw.rect function takes the following parameters:

• The display surface to draw the rectangle on
• The color of the rectangle
• A tuple of the rectangle's coordinates and dimensions

In this example, a blue rectangle with a width of 100 and a height of 50 is drawn at the coordinates (200, 150) on a white display surface.
