PyGame
! 1. 2. Um jogo tem os seguintes passos:
Setup game
Game loop
o o o o 3. handle events
update state
draw objects
show objects
Close down game

PyGame - Sprites
! Animation
Temos de criar um modo de apresentar as diversas
imagens em sequência.
PyGame - Sprites
! Animation
Apresentar as diversas
imagens em sequência
e
Efectuar o flip da imagem
de acordo com a direcção
do movimento.
