Python(Pygame) 按键错误

Question

我正在 pygame 使用 tilemap 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 = [

Answer 1

小提示，如果你想使用 tilemap 制作游戏，请使用 Tiled, also use TMX import library by Richard Jones。

而且您似乎正在尝试访问不在纹理中的元素。 tileMap 中的值为 174（倒数第三行）。

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

在这里您访问的元素在纹理字典中不存在。它被解释为：

textures[174]

并且由于纹理中没有这样的键，所以你有错误。
