Connect three swap game engine

[molkman]

Hello,
in the future, I want to make a game that features the common "swap and connect three" gameplay. Like, you have a board with symbols on it and swap two to create rows of three or more to make them disappear. Like this one: http://www.mausland.de/234.maus .

Now, I have no idea how to make a game like this. Does anyone know a tutorial for the technique needed to make a game like this? Someone told me that it is not hard. I know AS2 and have already created many flashgames, but I don't know what I need for this.

Also note, that I don't want to simply make a copy of that game I linked to, I just need an engine like this as part of the game I want to make, it'll only be a part of the game among other things, kind of like a twist etc.

it is complicated to explain but basically you need to tell it to to move to the new destination meaning grid movement and then it gets there it does a hitTest to see if there is the same movieclip as it's self next to it and if there is it gets deleted. i would make you an fla but that would be making an entire game for you and i would make the entire thing for someone or at least not for free.

^ I agree
do a class (level manager) which will hold a matrix and he will need to have a swap function (which will swap and chack the grid for matches) and a clear function (removes the blocks and drops new ones).

Okay, thanks, I'll see what I can do.

Good things to know about for this:
2-dimensional arrays
var newX:int = Math.round(PuzzlePiece(grid[oldX][oldY]).x/GRID_SPACING)
Basically, make GRID_SPACING a const that determines how far apart your pieces are, make grid a 2-dimensional array that contains all your pieces
