我必须创建一个迷宫游戏，它接收来自用户的命令以便玩游戏。我已经为迷宫游戏编写了代码。我想要修改的是仅在将迷宫打印给用户时显示部分迷宫（移动完成后）。这是我的迷宫：
level = [
["1"," ","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1"],
["1"," "," ","1","1","1","1","1","1","1"," "," "," "," "," "," "," "," "," "," ","1","1","1","1","1"],
["1"," "," ","1","1","1","1","1","1","1"," "," ","1","1","1","1","1","1"," "," ","1","1","1","1","1"],
["1"," "," "," "," "," "," "," ","1","1"," "," ","1","1","1","1","1","1"," "," ","1","1","1","1","1"],
["1"," "," "," "," "," "," "," ","1","1"," "," ","1","1","1"," "," "," "," "," "," "," "," ","1","1"],
["1"," ","1","1","1","1"," "," ","1","1"," "," ","1","1","1"," "," "," "," "," "," "," "," ","1","1"],
["1"," ","1","1","1","1"," "," ","1","1"," "," ","1","1","1","1","1","1"," "," ","1","1","1","1","1"],
["1"," ","1","1","1","1"," "," ","1","1"," "," "," "," ","1","1","1","1"," "," ","1","1","1","1","1"],
["1"," "," ","1","1","1"," "," "," "," "," "," "," "," ","1","1","1","1"," "," "," "," "," "," ","1"],
["1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1"," ","1"]
]
start_maze = level[0][1] #start of maze
end_maze = level[9][23] #end of maze
输出如下：
The initial configuration of the maze is:
1 X 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
如何制作它以便玩家只能在移动时看到迷宫的一部分，而不是能够看到结束（这使得它很容易）？
所以例如要有这样的视图：
1 1 1 1
1 1 1
1 X 1 1
1
1
即，他只能在每个方向看到2个其他细胞。
我希望我明白这个问题。如果需要，下面是主要游戏的代码部分：
player = {'y': 0, 'x': 1}
level[player['y']][player['x']] = 'X'
# Translate keywords into coordinate changes
move_modifications = {'UP': {'y': -1, 'x': 0},
'DOWN': {'y': 1, 'x': 0},
'LEFT': {'y':0, 'x': -1},
'RIGHT': {'y': 0, 'x': 1}}
def player_move(maze):
# Main game loop
play = True
while play:
move = input("Please enter a command (LEFT/RIGHT/UP/DOWN): ")
move = move.upper()
coords = move_modifications[move]
new_y = player['y'] + coords['y']
new_x = player['x'] + coords['x']
#Catch them if they try to leave the map
try:
maze_position = maze[new_y][new_x]
except IndexError:
print("Not on map")
continue
if maze_position != '1':
# Move on the map
maze[player['y']][player['x']] = ' '
maze[new_y][new_x] = 'X'
# Update player coords
player['y'] = new_y
player['x'] = new_x
# Print result
print_level(maze)
其余的代码只是移动，它不包括任何迷宫的打印。
NumPy数组可以方便地切割二维列表。考虑下面的代码和切片。
# load numpy from its module
import numpy as np
# create a numpy array
np_level = np.array(level)
# slice the map
slice = np_level[max(new_y-2,0) : new_y+3, \ # y slice
max(new_x-2,0) : new_x+3] # x slice
# print the slice
print(slice)
# or print_level(slice), whichever one suits your case
这需要你的二维数组level，制作一个NumPy数组np_level，然后从[y-2, y+3)和[x-2, x+3)（使用区间符号）范围打印一片。这意味着它将数组从y-2切换到y+2，从x-2切换到x+2。
如果max(y-2, 0)低于0（即负数），y-2就在那里。使用负开始索引和正结束索引进行切片将返回空列表（例如some_array[-1:1] ==> []）。 max(x-2, 0)也是如此。我们还可以为末尾索引添加min(y+3, <height-of-level>)和min(x+3, <width-of-level>)，但是数组切片已经处理了这些边缘情况 - 所以这一切都很好。
注：这需要安装NumPy模块。如果还没有，请通过在命令行/终端输入python -m pip install numpy来安装它。
