原理介绍
这是一个双人小游戏，分为红蓝两方。当然每队都有三个球员和一个守门员，每个玩家能够管制一个球员，其余三个是电脑管制。红方球员是通过“W”,“A”,“S”,“D”管制球员的挪动，“T”踢球。蓝方球员是通过“↑”,“↓”,“←”,“→”管制球员的挪动，“K”踢球。安空格键是开始游戏，上面是整个球场的效果图。
大略理解了游戏规则之后，咱们就能够开始写这个游戏啦~首先，进行一下游戏初始化操作：
def myinit(): screen = pygame.display.set_mode((769,563)) g1 = pygame.image.load("g1.jpg").convert() g2 = pygame.image.load("hh.png").convert() t = 0 timer = pygame.time.Clock() while(1): timer.tick(30) ticks = pygame.time.get_ticks(); for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() screen.blit(g1,(0,0)) t+= 1 print(t) if t > 66: break; pygame.display.update() while(1): timer.tick(30) ticks = pygame.time.get_ticks(); for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() if event.type == MOUSEBUTTONUP: mouse_up = event.button mouse_up_x,mouse_up_y = event.pos if mouse_up_x > 245 and mouse_up_x < 469 and mouse_up_y> 368 and mouse_up_y < 470: return screen.blit(g2,(0,0)) pygame.display.update()而后就是一部分的代码示意：
