pygame入门练习

1.画圆和矩形

import pygame
pygame.init()

screen = pygame.display.set_mode([640,480])
pygame.display.set_caption('Draw')


while 1:
    for event in pygame.event.get():
        if event.type == pygame.QUIT: pygame.quit()
    screen.fill([255,255,0])
    pygame.draw.circle(screen,[0,255,0],[100,100],30,0)
    pygame.draw.rect(screen,[0,0,255],[250,150,300,200],0)
    pygame.display.flip()

2.一个官方动画示例

import sys, pygame
pygame.init()

size = width, height = 640, 480
speed = [1, 1]
black = 255, 0, 0
 
screen = pygame.display.set_mode(size)
 
ball = pygame.image.load("ball.gif")
ballrect = ball.get_rect()

while 1:
    for event in pygame.event.get():
        if event.type == pygame.QUIT: pygame.quit()

    ballrect = ballrect.move(speed)
    if ballrect.left < 0 or ballrect.right > width:
        speed[0] = -speed[0]
    if ballrect.top < 0 or ballrect.bottom > height:
        speed[1] = -speed[1]

    screen.fill(black)
    screen.blit(ball, ballrect)
    pygame.display.flip()

没能做成动态的，见谅

注意：退出时是调用pygame,quit()，而不是sys.exit()。否则会非正常结束。
