使用用户输入在播放器周围移动播放器：“left dx Up dy”

Question

我使用以下代码制作了一个网格：

board = []
x = choice_size
y = x
for row in range(0,x):
    board.append(["()"]*y)

def print_board(board):
    for row in board:
        print(" ".join(row))

print_board(board)

我需要为用户提供输入输入的选项（例如"Left 10 Up 2"），然后将它们移动到电路板上的相应位置。

我已经尝试搞乱添加他们的数字到变量然后得到列表board中的x和y位置，但我似乎无法让它工作。

Answer 1

尝试通过添加或减去数字来改变x / y值，具体取决于玩家想要移动的方向。

Answer 2

这是如何移动玩家的示例

但它在重绘电路板之前使用Linux特殊符号来清除终端/控制台。

import time

# --- constants --- (UPPER_CASE names)

SIZE_X = 10
SIZE_Y = 5

SYMBOL_EMPTY  = '( )'
SYMBOL_PLAYER = '(@)'
#SYMBOL_DANGER = '(!)'

# --- functions --- (lower_case names)

def print_board(board):
    print('\33c') # clear terminal on Linux

    for row in board:
        print("".join(row))


def move_player(new_x, new_y):
    global player_x
    global player_y

    # remove in old place
    board[player_y][player_x] = SYMBOL_EMPTY

    # put in new place
    player_x = new_x
    player_y = new_y
    board[player_y][player_x] = SYMBOL_PLAYER

# --- main --- (lower_case names)

# creat board

board = [ ]

for row in range(SIZE_Y):
    board.append([SYMBOL_EMPTY] * SIZE_X)

# display empty board

print_board(board)
time.sleep(0.5)

# set player position and symbol

player_x = player_y = 0

board[player_y][player_x] = SYMBOL_PLAYER

# display board with player    

print_board(board)
time.sleep(0.5)

# move player

# move left
for new_x in range(SIZE_X):
    move_player(new_x, player_y)

    # redraw
    print_board(board)
    time.sleep(0.5)

# move down
for new_y in range(SIZE_Y):
    move_player(player_x, new_y)

    # redraw
    print_board(board)
    time.sleep(0.5)

真正的程序可能更复杂。

在控制台中可能存在清除屏幕重绘板和获取键/鼠事件以使其真实交互的问题。也许看看urwid或ncurses模块。

或者尝试像PyGame，Pyglet这样的图形模块
