So I'm trying to create a text based game, and someone suggested I store map data as a multi-dimensional array I have been trying to figure out how I'd do this or how I'd even navigate through a multi dimensional array. It seems to me this would be incredibly difficult but I have to ask because I won't be able to figure it out on my own. If this question is too vague let me know what should be more specific.

多维数组只不过是一个数组，其元素映射到另一个数组，通常其中每个“子数组”的大小都相等（但不严格）。

inner = [ "" ] * 10
outer = [ [].extend(inner) for x in inner ]

这将为您创建一个 10 x 10 元素的方形多维数组。

您可以通过以下方式访问这些元素：

outer[outer_index][inner_index]

只需在网格上可视化外部和内部以及索引，外部遍历 x 轴，内部遍历 y 轴。上面的数组看起来有点像这样：

"" "" "" "" "" "" "" "" "" "" 0
"" "" "" "" "" "" "" "" "" "" 1
"" "" "" "" "" "" "" "" "" "" 2
"" "" "" "" "" "" "" "" "" "" 3
"" "" "" "" "" "" "" "" "" "" 4  (inner)
"" "" "" "" "" "" "" "" "" "" 5
"" "" "" "" "" "" "" "" "" "" 6
"" "" "" "" "" "" "" "" "" "" 7
"" "" "" "" "" "" "" "" "" "" 8
"" "" "" "" "" "" "" "" "" "" 9
0  1  2  3  4  5  6  7  8  9

         (outer)

如果我在元素 6 和 8 处更新 external 的值，网格将被更改：

outer[6][8] = "X" # marks the spot

"" "" "" "" "" "" "" "" "" ""  0
"" "" "" "" "" "" "" "" "" ""  1
"" "" "" "" "" "" "" "" "" ""  2
"" "" "" "" "" "" "" "" "" ""  3
"" "" "" "" "" "" "" "" "" ""  4  (inner)
"" "" "" "" "" "" "" "" "" ""  5
"" "" "" "" "" "" "" "" "" ""  6
"" "" "" "" "" "" "" "" "" ""  7
"" "" "" "" "" "" "X" "" "" "" 8
"" "" "" "" "" "" "" "" "" ""  9
0  1  2  3  4  5  6  7  8  9

         (outer)

希望这可以帮助。

手动创建多维列表：

world_map = [['*', '*', '*', '*'],
             ['*', ' ', 'i', '*'],
             ['*', ' ', ' ', '*'],
             ['*', '*', '*', '*']]

*墙在哪里，i可能是玩家。要遍历这个世界地图，请使用两个 for 循环：

for row in world_map:
    for column in row:
        print(column, end="")
    print()

这将打印世界地图。

如果您需要向左移动玩家，您可以执行以下操作：

for row in world_map:
    for i, column in enumerate(row):
        if column == "i":
            if i > 0 and row[i - 1] == ' ':
                row[i - 1] = 'i'
                row[i] = ' '

world_map[row][column]如果您知道元素的位置，也可以直接访问元素。

你将不得不自己做剩下的事情。此外，这可能不是最好的方法，您应该使用播放器类等，但这对初学者来说很好:)
