如何将tiled的json数据转换为pygame关卡？

Question

我尝试纠正一些执行此操作的代码，但关卡变得混乱（将图块绘制到屏幕上，但没有绘制到正确的位置）。我相信问题可能出在我循环图像列表并尝试创建一个字典的部分，其中每个图像都有一个整数键。 ` 等级转换器类： def init(self, json_file_path): self.json_file_path = json_file_path

def convert_json_to_integer_list(self):
    with open(self.json_file_path, 'r') as file:
        json_data = json.load(file)
        layers = json_data["layers"]
        if len(layers) > 0:
            data = layers[0]["data"]
            return [int(tile_id) for tile_id in data]
        else:
            return []
def load_sprite_sheet(self, sprite_sheet_path, tile_size):
    self.sprite_sheet = pygame.image.load(sprite_sheet_path)
    tile_width, tile_height = tile_size,tile_size
    tile_images = []
    tile_mapping = {0:""}
    for y in range(0, self.sprite_sheet.get_height(), tile_height):
        for x in range(0, self.sprite_sheet.get_width(), tile_width):
            tile_images.append(self.sprite_sheet.subsurface(pygame.Rect(x, y, tile_width, tile_height)))
    for index, image in enumerate(tile_images, start=1): #The part I think may be wrong
        tile_mapping[index] = image

    return tile_mapping
def draw_tiles(self, surface,path, tile_width, tile_height):
    tile_list = self.convert_json_to_integer_list()
    tile_dict = self.load_sprite_sheet(path,tile_width)
    num_cols = surface.get_width() // tile_width
    num_rows = len(tile_list) // num_cols

    for i in range(num_rows):
        for j in range(num_cols):
            tile_index = i * num_cols + j
            tile_value = tile_list[tile_index]

            if tile_value in tile_dict:
                if tile_value == 0:
                    pass
                else:
                    tile_image = tile_dict[tile_value]
                    tile_image = pygame.transform.scale(tile_image, (tile_width, tile_height))
                    surface.blit(tile_image, (j * tile_width, i * tile_height))

`我还会附上 json 文件以防万一

Answer 1

我建议编写一个自定义类，它采用 json 级别并将其转换为表面（显然，每次迭代后将位置存储在每次增加高度或宽度的地方）

不用 OOP 也可以做到这一点，但随着时间的推移，你的代码会变得越来越糟，就像现在一样
