python - 使用 2 个坐标选择数组中的项目并填充它

Question

我正在为 Discord 服务器制作一个战舰游戏机器人。我还没有实现 Discord 部分，我仍在制定游戏的逻辑。

这是代码:

import numpy as np
import re

waters = np.zeros((10,10),'U2')

headers = ['A','B','C','D','E','F','G','H','I','J']

#PRINTS THE BOARD
for i,header in enumerate(headers):
    if i == 0:
        print('    ',end='')
    print(header + '  ',end='')
    if i == len(headers)-1: print()

for x,line in enumerate(waters):
    print('%2d'%(x),end='')
    for pos in line:
        if pos == '':
            print(' ##',end='')
        else:
            print(' '+pos,end='')
    print()

board_x_coord = {
    "A":0,
    "B":1,
    "C":2,
    "D":3,
    "E":4,
    "F":5,
    "G":6,
    "H":7,
    "I":8,
    "J":9
}

ship_type = [
    ["CV","Carrier",5],
    ["BB","Battleship",4],
    ["CA","Cruiser",3],
    ["SS","Submarine",3],
    ["DD","Destroyer",2],
]

def board_coord_to_npcoord(ship,coord):
    result = re.findall(r'([a-zA-Z0-9])',coord)
    try:
        if result[0] in headers:
            if int(result[1]) in range(0,9):
                if result[2] in headers:
                    if int(result[3]) in range(0,9):
                        x_crd_a = board_x_coord.get(result[0])
                        y_crd_a = int(result[1])
                        x_crd_b = board_x_coord.get(result[2])
                        y_crd_b = int(result[3])
                        print('X: %s , Y: %s , X: %s , Y: %s' %(x_crd_a,y_crd_a,x_crd_b,y_crd_b))
                        return True
        print('Error. Try again.')   
    except ValueError:
        print('Error. Try again.')
        return False

for ship in ship_type:
    while True:
        print('Coordinates for %s (%s): ' %(ship[1],ship[2]),end='')
        if board_coord_to_npcoord(ship[0],input()): break

董事会看起来像这样:

   A  B  C  D  E  F  G  H  I  J
 0 ## ## ## ## ## ## ## ## ## ##
 1 ## ## ## ## ## ## ## ## ## ##
 2 ## ## ## ## ## ## ## ## ## ##

 6 ## ## ## ## ## ## ## ## ## ##
 7 ## ## ## ## ## ## ## ## ## ##
 8 ## ## ## ## ## ## ## ## ## ##
 9 ## ## ## ## ## ## ## ## ## ##

脚本将询问坐标。前任。航母:A0E0，战列舰:A2A5

   A  B  C  D  E  F  G  H  I  J

如何用相应的船舶类型填充所选元素以及如何检测碰撞？

Answer 1

我做了第一个案例并进行了一些小的更改:

• 改进的正则表达式
• 使用“##”作为面板单元格的默认值
• 打印板变功能

import numpy as np
import re

waters = np.full((10,10), '##','U2')
headers = ['A','B','C','D','E','F','G','H','I','J']

#PRINTS THE BOARD

    for i,header in enumerate(headers):
        if i == 0:
            print('    ',end='')
        print(header + '  ',end='')
        if i == len(headers)-1: print()

    for x,line in enumerate(waters):
        print('%2d'%(x),end='')
        [print(' '+pos,end='') for pos in line]
        print()

printBoard()

        y_crd_a = int(result[1])
        x_crd_b = board_x_coord.get(result[2])
        y_crd_b = int(result[3])
        vertical = ship[2] == abs(x_crd_b - x_crd_a + 1) and y_crd_a == y_crd_b
        horizontal = ship[2] == abs(y_crd_b - y_crd_a + 1) and x_crd_a == x_crd_b
        valid = vertical or horizontal
        if valid == False:
            print('Invalid length')
            return False
        if vertical:

            print(waters[y_crd_a][x_crd_a:x_crd_b])
            printBoard()
