Dragging Question

Hi all,
I'm making a game where you drag letters to specific places to spell a word.

When the right letter reaches it's target I want to be able disengage the ability to drag the letter.

It works when you collide/overlap the target, but kinda sticks to the side of it. I can't seem to get it to stop in the middle of the target.

Any ideas much appreciated!

    What you need to do is let the Letter "snap" to the center of the target and then disable the drag ability.

    If your Letter and/or Target is quite big and the "snap" makes too much of a jump upon colliding/overlapping, then you have at least two options:

    a) upon collide/overlap do a proximity calculation between Target and Letter before the "snap" happens. I.e. only "snap" when the center of the Letter is within 20pixels from the center of the Target.

    b) constrain a smaller actor to the center of the Letter, same with the Target. Then put the collide/overlap "snap" logic into these smaller actors.
