這篇文章主要為大家詳細(xì)介紹了pygame游戲之旅的第10篇，教大家如何添加游戲界面按鍵圖形，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文為大家分享了pygame游戲之旅的第10篇，供大家參考，具體內(nèi)容如下

通過獲取鼠標(biāo)的位置然后進行高亮顯示：

mouse =pygame.mouse.get_pos()
 if 150 + 100 > mouse[0] > 150 and 450 + 50 > mouse[1] > 450:
  pygame.draw.rect(gameDisplay, bright_green, (150,450,100,50))
 else:
  pygame.draw.rect(gameDisplay, green, (150,450,100,50))
 if 550 + 100 > mouse[0] > 550 and 450 + 50 > mouse[1] > 450:
  pygame.draw.rect(gameDisplay, bright_red, (550,450,100,50))
 else:
  pygame.draw.rect(gameDisplay, red, (550,450,100,50))
