Making Chess puzzle in Flash

Question

Hi guys!
I'm pretty new to Flash, but I love chess and would like to
make chess puzzles in Flash to get more familiar with the program.
I've looked in my CS3 book and browsed google for tutorials, but
didn't find any on chess. Then I figured that maybe some nice
people at these forums would help me out!
I have a board and my pieces, and I imagine it like, say, 4
squares will be highlighted, and then the user can drag a chess
piece onto any of them, but only one will be right (the others
produce failure messages). Then when they find the right square, I
make the game make a move, and then they have to find the next
move, then the game moves, and then they have to find the mating
move.
Frankly, I don't know what to type in my actionscript for
this to happen.
Help me out a bit?
Thanks, Carina

Hi Carina,
just something to get you going, this could be a way to set
it up.
It assumes there's a number of movieClips on the stage with
instancenames like in the array.
it assumes you actually guide the player through a set of
moves like
replaying a done game, possible position of other pieces are
not taken
into account
Watch for wrapping...
// these are the square movieClipt that make up the board,
not a
complete board,
// nor the smartest way to set it up, but for a small POC
it's OK
var board:Array = new Array();
board.push( new Array( sq_00_mc, sq_01_mc, sq_02_mc,
sq_03_mc, sq_04_mc ) );
board.push( new Array( sq_10_mc, sq_11_mc, sq_12_mc,
sq_13_mc, sq_14_mc ) );
board.push( new Array( sq_20_mc, sq_21_mc, sq_22_mc,
sq_23_mc, sq_24_mc ) );
board.push( new Array( sq_30_mc, sq_31_mc, sq_32_mc,
sq_33_mc, sq_34_mc ) );
board.push( new Array( sq_40_mc, sq_41_mc, sq_42_mc,
sq_43_mc, sq_44_mc ) );
// possible moves this game
var moves:Array = new Array();
// first move of game, each move should contain a
startposition,
possible moves (and possible a 'solution-position'?)
moves.push( { startpos: {x: 3, y: 2}, possiblemoves: new
Array( {x: 3,
y: 1}, {x: 2, y: 2}, {x: 3, y: 3} ) } );
// etc. for other moves
// set move to 0, the first
var currentMove:uint = 0;
// load move into game
loadMove( moves[ currentMove ] );
function loadMove( aMove:Object )
// get square of current moveable piece
var currSquare:MovieClip = board[ aMove.startpos.y ][
aMove.startpos.x ];
// hilight startpos of currentMove
currSquare.transform.colorTransform = new ColorTransform( 1,
1, 1, 1,
0, 0, 128, 0 );
for ( var i:uint = 0; i < aMove.possiblemoves.length; i++
currSquare = board[ aMove.possiblemoves
.y ][
aMove.possiblemoves.x ];
trace( currSquare.name );
currSquare.transform.colorTransform = new ColorTransform( 1,
1, 1, 1,
0, 0, 128, 0 );
