鼠标控件无响应

Question

我刚刚开始使用pygame。我已经创建了我的游戏，但它真的很不稳定并且崩溃（退出时出现问题）。

我创建了一个欢迎页面，但它创建了一个游戏控制错误（鼠标控制的角色已停止响应），我尝试了一些方法，但只会导致更多的游戏崩溃和错误。 你能帮我调试你可能发现的任何东西吗？ 您从她的 http://dl.dropbox.com/u/47312995/Twerk.rar 下载游戏

问题是你没有检查输入。 每次通过游戏循环时，您应该调用pygame.event.get（）。 例如，从我的模板代码中：

def quit():
    pygame.quit(); sys.exit()
def GetInput():
    key = pygame.key.get_pressed()
    for event in pygame.event.get():
        if   event.type == QUIT: quit()
        elif event.type == KEYDOWN:
            if   event.key == K_ESCAPE: quit()
def Draw():
    pygame.display.flip()
def main():
    Clock = pygame.time.Clock()
    while True:
        GetInput()
        Draw()
        Clock.tick(60)
