pygame游戏之旅调用按钮实现游戏开始功能_Python

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：

1	`pygame.font.sysfont('comicsansms',115)`
