Python Pygame Display Set Mode Guide

Pygame is a popular library for creating games in Python. One of its core functions is pygame.display.set_mode. This function sets up the game window.

Before using Pygame, ensure it is installed. If not, follow our guide on How to Install Pygame in Python.

What is pygame.display.set_mode?

The pygame.display.set_mode function initializes a window or screen for display. It takes a tuple representing the window's size and optional flags.

Here’s a basic example:

import pygame

# Initialize Pygame
pygame.init()

# Set up the display window
screen = pygame.display.set_mode((800, 600))

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

    # Update the display
    pygame.display.flip()

# Quit Pygame
pygame.quit()
    

In this example, a window of 800x600 pixels is created. The pygame.display.flip function updates the display.

Parameters of pygame.display.set_mode

The pygame.display.set_mode function accepts three parameters:

• size: A tuple (width, height) defining the window size.
• flags: Optional flags to customize the display mode.
• depth: The number of bits to use for color.

Common flags include pygame.FULLSCREEN, pygame.RESIZABLE, and pygame.NOFRAME.

Example with Flags

Here’s how to create a resizable window:

import pygame

# Initialize Pygame
pygame.init()

# Set up a resizable display window
screen = pygame.display.set_mode((800, 600), pygame.RESIZABLE)

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

    # Update the display
    pygame.display.flip()

# Quit Pygame
pygame.quit()
    

This code creates a resizable window. Users can adjust the window size during runtime.
