newt. Thankyou for your comments, but I don't think we are thinking of the same thing. The plugin user defines the location of each sprite. Since a sprite and touch are both plugins, I suppose this plugin does interact with them, but just about every plugin does.
I can see what you mean about dragging not being in touch, I suppoe you could detect which sprite the touch lifts off to pick the sprite of choice, perhaps with a collision detection box dummy object as you suggest.
This kind of menu selection is ubiquitous in the phone app game world, so all of us doing it in events might not be the most efficient way to go about it.
I appreciate your taking the time to comment.
