我正在做一个记忆游戏，但我无法让程序检查瓷砖是否匹配，如果匹配，则瓷砖保持暴露状态，如果瓷砖不匹配，则将瓷砖暴露一秒钟。第116-122行我认为程序的该部分应该进行检查，但对于is_matching（）绝不会返回true。我觉得我应该检查实际的瓦片本身是否彼此相等，但是对我来说，这似乎适得其反，因为瓦片只是网格上的一个位置，图像是在瓦片上绘制的？
提前致谢

参考方案
这些图块不匹配，因为您实际要做的是比较图像对象：
self.match = self.first_image == self.second_image
但每个图片会加载两次。为每个图像生成不同的对象，因此它们将永远不匹配。
加载每个图像一次，并将其用于2个匹配的图块：
# define unique image names
new_image =['image1.bmp','image2.bmp','image3.bmp','image4.bmp',
'image5.bmp','image6.bmp','image7.bmp','image8.bmp']
# load each unique image
for file_name in new_image:
image = pygame.image.load(file_name)
self.images.append(image)
# create a list where each loaded image object is used twice
self.images = self.images + self.images
此外，由于图像名称的编号有所不同，因此可以简化名称列表的定义：
new_image = ['image' + str(i) + '.bmp' for i in range(1,9)]

那时间延迟呢
完全删除self.first_image和self.second_image。适应Tile：
class Tile:
# [...]
def __eq__(self, other_tile):
return self.image == other_tile.image
单击磁贴后，将其保留在self.tile1和self.tile2中。第一次单击时，如果不匹配，则隐藏暴露的图块：
if self.click == 0:
if self.tile1 != self.tile2:
if self.tile1:
self.tile1.hide_tile()
if self.tile2:
self.tile2.hide_tile()
第二次点击时，请设置必须自动覆盖的时间（例如pygame.time.get_ticks() + 2000）：
elif self.click == 1:
self.tile2 = tile
self.hide_time = pygame.time.get_ticks() + 2000
评估是否必须在update中覆盖图块：
ticks = pygame.time.get_ticks()
if self.tile1 and self.tile2:
if self.tile1 != self.tile2 and self.hide_time > 0 and ticks > self.hide_time:
self.tile1.hide_tile()
self.tile2.hide_tile()
更改您的代码：
class Game:
def __init__(self, surface):
# [...]
self.hide_time = 0
# [...]
def update(self):
ticks = pygame.time.get_ticks()
self.score[0] = ticks // 1000
if self.tile1 and self.tile2:
if self.tile1 != self.tile2 and self.hide_time > 0 and ticks > self.hide_time:
self.tile1.hide_tile()
self.tile2.hide_tile()
def handle_mouse_up(self,event):
self.hide_time = 0
if self.click == 0:
if self.tile1 != self.tile2:
if self.tile1:
self.tile1.hide_tile()
if self.tile2:
self.tile2.hide_tile()
tiles = [t for row in self.board for t in row if t.select(event.pos) and not t.covered]
if any(tiles):
tile = tiles[0]
if self.click == 0:
self.tile1 = tile
elif self.click == 1:
self.tile2 = tile
self.hide_time = pygame.time.get_ticks() + 2000
tile.expose_tile()
self.click += 1
if self.click > 1:
self.click = 0
# [...]
def check_matching(self):
self.match = self.tile1.image == self.tile2.image
return self.match
