My question is instead of using coordinates to move can i assign numbers and letters so i can move with those values
Edit: I am outputting the board to html 8x8 table
$square = array( // A B C D E F G H
0 array(0,0,0,0,0,0,0,0),
1 array(0,0,0,0,0,0,0,0),
2 array(0,0,0,0,0,0,0,0),
3 array(0,0,0,0,0,0,0,0),
4 array(0,0,0,0,0,0,0,0),
5 array(0,0,0,0,0,0,0,0),
6 array(0,0,0,0,0,0,0,0),
7 array(0,0,0,0,0,0,0,0),
);
so when the user inputs : From: F1 to: G2 the pieces move
wouldn't it be better is i do this
Array ( 'A' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 )
'B' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 )
'C' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 )
'D' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 )
'E' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 )
'F' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 )
'G' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 )
'H' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 )
);
parseSquareFrom
function parseSquareFrom() {
if (strlen($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]][$coords[1]]; // for example
}
and parseSquareTo
function parseSquareTo() {
if (strlen($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
}
can i use that with this code
$board[$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
or is the $piece = $board[$coords1[0]][$coords1[1]]; cannot be used
