Checker demo

Am try to re-make the checker so that is one player and one AI player. I have load the checker board and made the tile map ( the logic checker board) just like the checkerdemo that came with TGB. But am have a hard time get the checker pices to load from scripts.

I use this to check for the place to the checker:

function CheckerBoard::isBlack(%this, %x, %y)
{
// this will decide if a checkerboard slot is black
if( (%x % 2) && (%y % 2) )
return true;
else if( %x % 2 || %y % 2 )
return false;
else
return true;
}

this to set the checker

function CheckerBoard::setPiece(%this, %x, %y, %type)
{
// set the board's array position
%this.board[%x,%y] = %type;
}

and

function CheckerBoard::init(%this)
{
// init the team counts
$redCount = 0;
$blueCount = 0;

// loop through and create the server board
for(%x = 0; %x < 8;%x++)
{
for(%y = 0;%y < 8;%y++)
{
// check if this is a black checkerboard spot
if(%this.isBlack( %x, %y ))
{
// check if this is a checker's starting spot
if(%y < 2)
{
// set the the red team's piece and add to the count
%this.setPiece(%x, %y, $red);
$redCount++;
} else if( %y > 5 )
{
// set the the blue team's piece and add to the count
%this.setPiece(%x, %y, $blue);
$blueCount++;
} else
{
// set the blank spot
%this.setPiece(%x, %y, $none);
}
}
else
{
// set the blank spot
%this.setPiece(%x, %y, $none);
}
}
}
}

but no checker load. Is there an easier way to do this? Could some one point me in the right way?
