Question

所以我正在尝试创建一个基于文本的游戏，有人建议我将地图数据存储为多维数组，我一直试图弄清楚我是如何做到的，或者我是如何导航的多维数组。在我看来，这将是非常困难，但我不得不问，因为我无法自己解决这个问题。如果这个问题太模糊，请告诉我应该更具体的问题。

Answer 1

多维数组只不过是一个数组，其元素映射到另一个数组，通常每个“子数组”的大小相等（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，外部穿过x轴，内部穿过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)

如果我更新元素6和8的外部值，则网格将被更改：

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)

希望这有帮助。

Answer 2

手动创建多维列表：

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

其中*是墙，i可以是玩家。要遍历此世界地图，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] = ' '

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

你必须自己完成剩下的工作。此外，这可能不是最好的方法，你应该使用类播放器等，但这适用于初学者：）
