  1. Meet Pygame • Noah Kantrowitz • June 8, 2007

  2. The Basics • Cross-platform • Based on SDL (don’t quote me on that) • Handle input (keyboard, mouse) and output (graphics, audio)

  3. Starting Up • import pygame • pygame.init() • Cue music ...

  4. The Screen • screen = pygame.display.set_mode((x, y)) • screen = pygame.display.get_surface() • pygame.display.flip() • pygame.display.update(dirty)

  5. Surfaces • The basic element of graphics • pygame.image.load(file) • .convert_alpha() vs .set_colorkey((r,g,b)) • dest.blit(src, (x, y))

  6. JPEG PNG GIF BMP PCX TGA TIF LBM PBM XPM Formats • Native support for the following: • SVG will need to worked out • Stay tuned ...

  7. The Loop • while True: <timing> <event handling> <update phase> <draw phase>

  8. The Loop • while True:<timing> <event handling> <update phase> <draw phase>

  9. Timing • from pygame.time import Clock • clock = Clock() • delta = clock.tick(30)

  10. The Loop • while True: <timing><event handling> <update phase> <draw phase>

  11. Event Handling • for evt in pygame.event.get(): if evt.type == pygame.QUIT: sys.exit() ...

  12. QUIT KEYUP KEYDOWN MOUSEMOTION MOUSEBUTTONUP MOUSEBUTTONDOWN Event Handling • Other types:

  13. Key Events • evt.key == pygame.K_a • See the Pygame documentation for the full list of key constants.

  14. Mouse Events • evt.pos • evt.button (for the button events)

  15. The Loop • while True: <timing> <event handling><update phase> <draw phase>

  16. Sprites • pygame.sprite.Sprite • class Foo(Sprite): • Must call superclass __init__() • .image, .rect

  17. Groups • pygame.sprite.Group • RenderUpdates, OrderedUpdates • .add(), .remove() • .update(*args) • More on these in a moment

  18. The Loop • while True: <timing> <event handling> <update phase><draw phase>

  19. Drawing • .draw(dest) • Dirty updates • pygame.draw.update(dirty)

  20. top bottom left right topleft bottomleft topright bottomright midtop midbottom midleft midright center centerx centery size width height Rects • pygame.Rect(left,top,width,height) • surf.get_rect()Always at (0,0) • Attributes:

  21. Collisions • Rect-based • spritecollide(sprite,group,kill) • spritecollideany(sprite,group) • groupcollide(group1,group2,kill1,kill2)

  22. Sound • pygame.mixer.Sound(file) • .play(), .stop() • pygame.mixer.music

  23. Text • Try to avoid it for now.
