Question

我正在使用tilemap在pygame中制作游戏，我遇到了以下错误

"Traceback (most recent call last):
    File "C:\Users\Dusty\Dropbox\~MAIN FOLDER~\Projects\Sunless\game.py", line 52, in <module>
    surface.blit(textures[tileMap[row][column]], (column*tileSize, row*tileSize, tileSize, tileSize))
KeyError: 174"

使用此代码：

import pygame

gameIsRunning = True

tileSize = 32
mapHeight = 19
mapWidth = 25

surface = pygame.display.set_mode((tileSize * mapWidth, tileSize * mapHeight))
pygame.display.set_caption("Game")

floor = 109
wall = 166

textures = {
            floor : pygame.image.load('data/floor.png'),
            wall: pygame.image.load('data/wall.png'),

            }

tileMap = [

小提示，如果你想使用瓷砖地图使用Tiled制作游戏，也可以使用TMX import library by Richard Jones。

此外，您似乎正在尝试访问纹理中不存在的元素。 tileMap中的值为174（距离结尾的第3行）。

surface.blit(textures[tileMap[row][column]]

在这里，您可以访问纹理词典中不存在的元素。它被解释为：

textures[174]

由于纹理中没有这样的键，你就会出错。

Python（Pygame）键错误
