Question

我目前正在用python编写一个推箱子游戏，我是该语言的新手，我正在使用列表字典来存储我的电路板，到目前为止我已经设法让我的角色移动（尽管没有到目前为止的任何检查。）

我现在正在尝试编写一个单独的函数，当字符位于框旁边且对方有空格时，框允许框移动位置。

我理解如何编写逻辑来执行这些检查和任务，但是我无法理解我如何能够从move_box（）函数中的move_player（）函数访问player_position，box_position和temp_board 。

有人可以给我一个如何做到这一点的想法吗？我尝试制作这些全局变量但是在move_box（）函数中实例化它时不会定义它

这是我的代码:(我试图在python小提琴上设置它，但它不会让我分享链接或运行，抱歉）

import copy

# Level constructs
r_t_corner = "\u2510"
l_t_corner = "\u250C"
l_b_corner = "\u2514"
r_b_corner = "\u2518"
v_wall = "\u2502"
h_wall = "\u2500"

# Game variables
player = "@"
box = "\u2588"
goal = "."
direction = ""


# Level Dictionary set up
levels = [{'board': [[l_t_corner, h_wall, h_wall, h_wall, h_wall, h_wall,     h_wall, h_wall, r_t_corner],
                 [v_wall, " ", " ", " ", " ", " ", " ", " ", v_wall],
                 [v_wall, " ", " ", " ", " ", " ", " ", goal, v_wall],

Answer 1

您可以将它们设为全局（与direction一样）或将它们作为函数之间的参数传递。

我不明白你把它们变成全球性的问题，但是你还没有表明你是如何尝试这样做的。

从单独的函数中移动2D列表字典中的元素？
