Python:Pygame basics

Introduction

Pygame is a Python module built on top of SDL.

This tutorial will go through a Python script that initializes Pygame, sets a 640 by 480 display, wait for a key press, and exit.

Requirements: Python, Pygame

The Script

PygameBasic.py

#!/usr/bin/env python 

import pygame
from pygame.locals import *

# optional
if not pygame.font: print 'Warning, no fonts'
if not pygame.mixer: print 'Warning, no sound'

pygame.init()
screen = pygame.display.set_mode((640, 480))
pygame.display.set_caption('Pygame Caption')
pygame.mouse.set_visible(0)

screen.fill((0, 0, 0))
pygame.display.flip()

while (pygame.event.wait().type != KEYDOWN): pass

Step by step explanation

Import

import pygame
from pygame.locals import *

Import the Pygame module, throwing an exception if unable to import.

Check for fonts and sound

# optional
if not pygame.font: print 'Warning, no fonts'
if not pygame.mixer: print 'Warning, no sound'

Check to see if font support and sound is available, print a warning if not found.

pygame.init()
screen = pygame.display.set_mode((640, 480))
pygame.display.set_caption('Pygame Caption')
pygame.mouse.set_visible(0)

Initialize Pygame. Set the display mode to 640 by 480, using the default/system color depth. Set the caption to 'Pygame Caption'. Set the mouse to be invisible.

screen.fill((0, 0, 0))
pygame.display.flip()

Fill the screen to black, color value (0, 0, 0). Update/flip the screen buffer.

while (pygame.event.wait().type != KEYDOWN): pass

While waiting for events that are not a key press, do nothing. This will loop until a key is pressed.
