Question

我正在pygame中开发一款名为“ Memory”的游戏。我正在尝试使表面上的图像模糊不清。我想获得8张成对成对的图像，但每次运行随机排列。但是，它在4 * 4网格中显示16个相同的图像，而不是2组的8个不同的图像。我不知道应该在哪里更改以解决此问题。有人请帮帮我！非常感谢。

市长的问题是，经过改组的图像包含在self.shuffle中，而不是self.images中：

~~one_tile = Tile(x, y, tile_width, tile_height, self.images[i], self.surface)~~

one_tile = Tile(x, y, tile_width, tile_height, self.shuffle[i], self.surface)

可以通过i = col_num*size + row_num计算图像的索引：

class Game:

   # [...]

   def create_grid(self, grid_size):
      for row_num in range(grid_size):
         new_row = self.create_row(row_num, grid_size)
         self.grid.append(new_row)

   def create_row(self, row_num, size):
      tile_height = self.surface.get_height() // size
      tile_width = self.surface.get_width() // (size+1)
      one_row = [ ]
      for col_num in range(size):
         x, y = col_num * tile_width + 5, row_num * tile_height + 5
         i = col_num*size + row_num
         one_tile = Tile(x, y, tile_width, tile_height, self.shuffle[i], self.surface)
         one_row.append(one_tile)
      return one_row

注意self.grid = [ [] ]是一个包含1个元素的列表，这是另一个列表。它必须是self.grid = []。

行

screen.blit(pygame.image.load(self.imagelist),(self.pos_x,self.pos_y))

每次图像blit到窗口表面时，都会导致图像从文件加载。这将对性能产生影响。

预载图像：

class Game:

   def __init__(self, surface):
      self.surface = surface
      self.bg_color = pygame.Color('black')
      self.FPS = 10
      self.game_Clock = pygame.time.Clock()
      self.close_clicked = False
      self.continue_game = True
      Tile.set_surface(self.surface)
      self.grid_size = 4
      self.grid = []

      imgnames = ['./images/' + str(i) + '.jpg' for i in range(1,9)]
      self.images = [pygame.image.load(name) for name in imgnames]
      self.shuffle = self.images + self.images
      random.shuffle(self.shuffle) 

      self.create_grid(self.grid_size)

blit到窗口的阶梯曲面：

class Tile:
   def __init__(self, pos_x, pos_y, tile_numx, tile_numy, image, surface):
      self.pos_x = pos_x
      self.pos_y = pos_y
      self.numx = tile_numx
      self.numy = tile_numy
      self.image = image
      self.surface = surface

   @classmethod
   def set_surface(cls, surface):
      cls.surface = surface   

   def draw(self):
      self.surface.blit(self.image,(self.pos_x,self.pos_y))
