Question

我的问题是，不是使用坐标来移动，我可以分配数字和字母，这样我就可以使用这些值移动

编辑：我正在将电路板输出到html 8x8表

$square = array( //    A B C D E F G H     
               0 array(0,0,0,0,0,0,0,0),
               1 array(0,0,0,0,0,0,0,0),
               2 array(0,0,0,0,0,0,0,0),
               3 array(0,0,0,0,0,0,0,0),
               4 array(0,0,0,0,0,0,0,0),
               5 array(0,0,0,0,0,0,0,0),
               6 array(0,0,0,0,0,0,0,0),
               7 array(0,0,0,0,0,0,0,0),
);

所以当用户输入时：从：F1到：G2，棋子移动

我这样做会不会更好

Array ( 'A' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'B' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'C' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'D' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'E' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'F' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'G' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'H' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 

    );

parseSquareFrom

function parseSquareFrom() {
    if (strlen($square) != 2) {
    return FALSE;
    }

    $coords = array(ord('A') - ord($square[0]),
            $square[1] - 1);


    // Perform bounds-checking.
    if ($coords[0] < 0 || $coords[0] > 7 || $coords[1] < 0 || $coords[1] > 7) {
    return FALSE;
    }

    return $coords;
}
$coords = parseSquare($square);
if ($coords === FALSE) {
    // Invalid input, handle this case.
} else {
    $piece = $board[$coords[0]][$coords[1]]; // for example
}

和parseSquareTo

function parseSquareTo() {
    if (strlen($square1) != 2) {
    return FALSE;
    }

  $coords1 = array(ord('A') - ord($square1[0]),
            $square1[1] - 1);


    // Perform bounds-checking.
    if ($coords1[0] < 0 || $coords1[0] > 7 || $coords1[1] < 0 || $coords1[1] > 7) {
    return FALSE;
    }

    return $coords1;
}

$coords1 = parseSquare($square);
if ($coords1 === FALSE) {
    // Invalid input, handle this case.
} else {
    $piece = $board[$coords1[0]][$coords1[1]]; // for example
}

我可以使用此代码吗

    $board[$coords1[0]-1][$coords1[1]+1] = $board[$coords[0]][$coords[1]];
    $board[$coords[0]][$coords[1]] = 0;

    //eating action
    $board[$coords1[0]][$coords1[1]] = 0;
    $board[$coords1[0]-2][$coords1[1]+2] = $board[$coords[0]][$coords[1]];

    //if player is 'up' then the value of $way is 1 so
      $board[$x+(-1*$way)][$y+(1*$way)] = $board[$coords[0]][$coords[1]]; // position 2,2 becomes 1,3
   //if player is not 'up' then the value of $way is -1 so
      $board[$x+(-1*$way)][$y+(1*$way)] = $board[$coords[0]][$coords[1]]; // position 2,2 becomes 3,1

或者是$ piece = $ board [$ coords1 [0]] [$ coords1 [1]];不能使用

Answer 1

是：将输入字符串解析为X，Y对。例如：

function parseSquare($square) {
    if (strlen($square) != 2) {
        return FALSE;
    }

    $coords = array(ord('A') - ord($square[0]),
                    $square[1] - 1);

    // Perform bounds-checking.
    if ($coords[0] < 0 || $coords[0] > 7 || $coords[1] < 0 || $coords[1] > 7) {
        return FALSE;
    }

    return $coords;
}

因此给出了像$square = "F5";

这样的方形字符串

$coords = parseSquare($square);
if ($coords === FALSE) {
    // Invalid input, handle this case.
} else {
    $piece = $board[$coords[0]][$coords[1]]; // for example
}

Answer 2

是的，你可以这样做。您只需要确保能够使用某种算法移动到该区域，并确保在移动它们时更改值。
