Dragging and dropping objects from a group

[Morthian]

I'm working on a board game. I want to click and drag a piece and place it on a space on the board.
Each game piece is part of a group (qualifier: Good). Each space on the board is part of another group (qualifier: Areas).

How can I program it so that when I click on an object from the "Good" group (a game piece), I can drag it to an object from the "Areas" group (a board space),
and the position of that game piece will be repositioned onto the position coordinates of the board space it was dragged to?

Each game piece object has a distinct number in an alterable value of the object called "piece number",
and each board space object has a distinct number in an alterable value of the object called "space number".

e.g.: one might drag a game piece object with "piece number" alterable value of "3" to a board space object with "space number" alterable value of "14".

Well when you click on a piece, you would flag it to indicate it can be dragged. Then you make another condition checking for mouse down and for that object being flagged. If so, then move that object's position relative to the mouse. This will get the dragging part accomplished.

Then you set up another event that checks for mouse button release, along with that object being flagged, and then check that object's position in relation to the board game space. This could be done a ton of different ways... from overlap checks, to checking for the nearest board space compared to the x,y of the dragged piece, etc... You can figure out what works best.

Then you just snap that piece to the board's x,y.. Depending on how you've set up your hot spots/action points, this could be very easy.

Thanks. Flagging the object did the trick.
