Question

嗨，我正在创建一个程序，该程序使用我创建的图片创建随机地图，然后允许用户在屏幕上移动字符，我正在尝试对其进行测试，但始终会出现此错误。

回溯（最近通话最近）：文件 “d：\地图maker.py”，行89，在 display.blit（瓷砖[DMAP [行] [列]]，（列 tileSize，行 tileSize）） KeyError：Surface（40x40x32 SW）

如果你可以看看我的代码，并告诉我如何解决它，我将非常感激。谢谢

您在这里有错误；

for row in range (mapHeight):
    for column in range(mapWidth):
        display.blit(tiles[dmap[row][column]], (column*tileSize,row*tileSize))  # wrong
        display.blit(player,(pposition[0]*tileSize,pposition[1]*tileSize))

应该是这样；

for row in range (mapHeight):
    for column in range(mapWidth):
        display.blit(dmap[row][column], (column*tileSize,row*tileSize))  # fixed
        display.blit(player,(pposition[0]*tileSize,pposition[1]*tileSize))

我如何解决这个python / pygame程序中的“键错误”？
