[AS3] Gomoku (5 in a row) board game

[Keys]

Hey there. I've just started out making a board game in AS3. Its a 15x15 grid of squares. It's a two player game where each player takes their turn to place their counter on the board. The first player to manage to get 5 of their counter in a row (up-down,left-right or diagonally) wins the game.


I believe i need to use e.currentTarget to make the event handlers function on every square. Could someone tell me how to do this?
Thanks in advance.

Hi,

You are on the right track with the e.currentTarget. In your case, though, you would use Evt.currentTarget, as the event is defined as Evt rather than the commonly used 'e':

function clickSquare(Evt:MouseEvent):void {
var myColor:ColorTransform = (Evt.currentTarget).transform.colorTransform;
myColor.color = 0xFFF000;
(Evt.currentTarget).transform.colorTransform = myColor;
}

Right I’ve got it working now so that player one can click a tile to add their colour, then the other player clicks and adds their colour.

So I just need to do one more thing. Being able to check that the player has made a winning move. 5 of their tiles in a row in any direction.
I’m thinking I’ll need to find the neighbouring index in the array in every direction each time a piece is played, then if it contains another piece of the same colour, move in that direction and count how many places it has moved until it equals 5. Any idea how to do this?

Checking through 2d arrays with as3 is fast, so the most straightforward way to do this would be to check the entire array for chains.

Write a for loop that cycles through the entire array, and for each block, run a function that establishes temp_chain_length = 0, checks down, right, and diagonally down and right, then, if that returns true, temp_chain_length++, and repeat with the tile and direction that returned true. When you hit chain length of 5, game over.

Could you perhaps show me how the code might look for that? I can't quite get my head around it.
