pygame游戏之旅 调用按钮实现游戏开始功能

本文为大家分享了pygame游戏之旅的第12篇，供大家参考，具体内容如下

实现点击功能：

click = pygame.mouse.get_pressed()print(click)if x + w > mouse[0] > x and y + h > mouse[1] > y:  pygame.draw.rect(gameDisplay, ac, (x,y,w,h))  if click[0] == 1 and action != None:    action()

修改显示文字：

pygame.font.SysFont('comicsansms',115)
