Pygame使用PyTMX加载Tilemap

我试图理解pygame中的tilemaps,并学习如何使用Tiled Map Editor,但我无法成功加载pygame中的地图。 这是代码:

import pygame
import pytmx

pygame.init()

display = pygame.display.set_mode((600,400))
clock = pygame.time.Clock()

gameMap = pytmx.TiledMap("map.tmx")

while(True):

    clock.tick(60)
    keys = pygame.key.get_pressed()

    for event in pygame.event.get():
        if(event.type == pygame.QUIT):
            quit()

    if(keys[pygame.K_ESCAPE]):
        quit()

    for layer in gameMap.visible_layers:
            for x, y, gid, in layer:
                tile = gameMap.get_tile_image_by_gid(gid)
                if(tile != None):
                    display.blit(tile, (x * gameMap.tilewidth, y * gameMap.tileheight))

    pygame.display.update()

它一直给我这个错误:

  

追踪(最近一次通话):     文件“main.py”,第27行,in       display.blit(tile,(x * gameMap.tilewidth,y * gameMap.tileheight))   TypeError:参数1必须是pygame.Surface,而不是元组

我知道当我在控制台中打印瓷砖时,这就是我得到的

(一个元组): ('img/NES - Super Mario Bros - Tileset.png', (0, 144, 16, 16), TileFlags(flipped_horizontally=False, flipped_vertically=False, flipped_diagonally=False))

在pygame中成功加载tilemap的最简单方法是什么?我做错了什么?

我认为以下内容涵盖了渲染mapSurface并使用updateloadMap在其上绘制内容的大多数机制。我没有任何真正的TMX文件可供测试。因人而异。祝你好运。

import time
import pygame
import pytmx


class TiledMap():
""" This is creating the surface on which you make the draw updates """
    def __init__(self):
        self.gameMap = pytmx.load_pygame("map.tmx", pixelalpha=True)
        self.mapwidth = self.gameMap.tilewidth * self.gameMap.width
        self.mapheight = self.gameMap.tileheight * self.gameMap.height

    def render(self, surface):
        for layer in self.gameMap.visible_layers:
            if isinstance(layer, pytmx.TiledTileLayer):
                for x, y, gid in layer:
                    tile = self.gameMap.get_tile_image_by_gid(gid)
                    if tile:
                        surface.blit(tile, (x * self.gameMap.tilewidth, y * self.gameMap.tileheight))

    def make_map(self):
        mapSurface = pygame.Surface((self.mapwidth, self.mapheight))
        self.render(mapSurface)
        return mapSurface

pygame.init()


class Display():
""" This is the class that makes the changes that you want to display. You would add most of your changes here. """

    def __init__(self):

        self.displayRunning = True
        self.displayWindow = pygame.display.set_mode((600, 400))
        self.clock = pygame.time.Clock()

    def update(self):

        pygame.display.set_caption("{:.2f}".format(self.clock.get_fps()))
        pygame.display.update()

    def loadMap(self):

        self.map = TiledMap()
        self.map_img = self.map.make_map()
        self.map_rect = self.map_img.get_rect()

    def displayLoop(self):

        self.clock.tick()
        self.update()
        self.loadMap()

# Here is the start of the main driver


runDisplay = Display()

runDisplay.update()
runDisplay.loadMap()
time.sleep(60)

如果您希望它在循环中运行,那么您可以将底部驱动程序块更改为:

runDisplay = Display()
while runDisplay.displayRunning is True:
    runDisplay.displayLoop()

使用:

gameMap = pytmx.load_pygame("map.tmx")

代替:

gameMap = pytmx.TiledMap("map.tmx")
