What’s Pygame ?

• Cross-platform set of Python modules • designed for writing video games• No need knowledge about C, OpenGL, ….• Pyweek Contest– Write a game during one week using Python

Pygame’s core module• pygame• pygame.Surface• pygame.Rect• pygame.sprite.Sprite• pygame.display• pygame.event• …

Hello world in Pygameimport sys import pygame if not pygame.font: print 'Warning, fonts disabled' pygame.init() size = width, height = 640, 480 screen = pygame.display.set_mode(size) while True:

if pygame.font: # render font and set position font = pygame.font.Font(None, 36)text = font.render("Hello World !", 1, (255, 0, 0)) textpos = text.get_rect(centerx=width/2)# draw to screen screen.blit(text, textpos) # change buffer pygame.display.flip()

Mario Clone

• Purpose ?– Learn basic game development principle– Learn to code with Python

• Platform game• (Try) minic the good old Super Mario Bros• New features ?

Sprite (1)

• Core class for each object in game• 2 important properties– image : what we see on screen– rect : position and bounding box of object

• How to load and draw image ?img = pygame.image.load(“mario.png”)screen.blit.(img, (100, 100))

Sprite (2)

• self.image

• Crop to each frame• Change and blit it on screen according to

object state

Sprite (3)

• self.rect -> rectangle

• Used to check collision with other object

Map

• TMX file (Tilemap XML)

• Tiled (www.mapeditor.org/)• Pygame: TMX library written by Richard Jones

Tileset

Map with layer

• Z-order• Background layer• Midground layer– Mario– Turtle– Coinbox, Coin, ….
