Question

我有两个2D数组，每个数组都包含显示图层的信息：

layer0 = [[info], [info]]
layer1 = [[info], [info]]

我想在另一个数组中包含这两个2D数组：

map = [[layer0], [layer1]]

但是，我的程序无法正确显示切片。我的问题是：是否可以在另一个2D阵列中存储2D数组？谢谢。

我有一个循环系统，用于迭代所述数组并显示与数组内容相对应的切片：

for array in maplayer:
            for tile in array:
                if tile == 0:
                    screen.blit(self.tile_dict[0], (self.tileX, self.tileY))
                    self.tileX = self.tileX+16
                if tile == 1:
                    screen.blit(self.tile_dict[1], (self.tileX, self.tileY))
                    self.tileX = self.tileX+16
            self.tileX = self.cameraX
            self.tileY += 16

我尝试添加另一个简单的for循环，迭代实际的地图数组，但PyGame显示一个空白屏幕：

for maplayer in map:
        for array in maplayer:
            for tile in array:
                if tile == 0:
                    screen.blit(self.tile_dict[0], (self.tileX, self.tileY))
                    self.tileX = self.tileX+16
                if tile == 1:
                    screen.blit(self.tile_dict[1], (self.tileX, self.tileY))
                    self.tileX = self.tileX+16
            self.tileX = self.cameraX
            self.tileY += 16

以下是完整的方法：

def LoadMap(self, map):
    self.tileX = self.cameraX
    self.tileY = self.cameraY
    for maplayer in map:
        for array in maplayer:
            for tile in array:
                if tile == 0:
                    screen.blit(self.tile_dict[0], (self.tileX, self.tileY))
                    self.tileX = self.tileX+16
                if tile == 1:
                    screen.blit(self.tile_dict[1], (self.tileX, self.tileY))
                    self.tileX = self.tileX+16
            self.tileX = self.cameraX
            self.tileY += 16

感谢。

我在阅读2D数组时也做了同样的事情，实际上无法理解为什么需要将数组放在另一个数组中。我使用此代码从文件中创建数组：

gameMap = [list(row.rstrip('\n')) for row in open('Room 1.txt')]

然后阅读它：

for i in range(0, len(gameMap)):

    for x in range(0, len(gameMap[i])):
        xC = x * 30
        y = i * 30

        if gameMap[i][x] == "*":
            screen.blit(wallImage, (xC, y))

        elif gameMap[i][x] == ".":
            screen.blit(floorImage, (xC, y))

        elif gameMap[i][x] == "+":

            if playerDirection == "up" or playerDirection == "":
                screen.blit(playerForwardImage, (xC, y))

            elif playerDirection == "right":
                screen.blit(playerRightImage, (xC, y))

            elif playerDirection == "left":
                screen.blit(playerLeftImage, (xC, y))

            elif playerDirection == "down":
                screen.blit(playerDownImage, (xC, y))

        elif gameMap[i][x] == "#":
            pygame.draw.rect(screen, black, (xC, y, 30, 30))

        elif gameMap[i][x] == "=":
            pygame.draw.rect(screen, red, (xC, y, 30, 30))

希望有所帮助，对于为什么你甚至需要把它放在另一个数组中有点困惑。
