我在pygame中有一个记忆游戏的代码。我试图解决的问题是，一旦用户选择了两张不匹配的卡，就会将卡片向下翻转。如果任何人可以帮助那将是伟大的。谢谢！

答案 0 :(得分：2)
如果是同一张图片，则会加载许多副本。而是加载playing-card-back.jpeg一次，然后重复使用。
每个循环都会进行多次blitting，每次触发事件一次。
for event in pygame.event.get():
screen.blit(img1,(10,25,100,100))
screen.blit(img2,(10,250,100,100))
相反，每帧渲染一次：
# handle events
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
# ...
# draw
screen.blit(img1,(10,25,100,100))
# ...
# flip
pygame.display.flip()
使用Rect.collide*检查点击是否在我们想要的范围内
# instead of
if (x in range (10,110)) and (y in range (250,350)):
# use
for card in cards:
if card.rect.collidepoint(x,y)
print("You clicked on {}".format(card))
