Well i need something like this.
When touch/drag to identify this object (A) so that i can set event
when he (A) is dragged and is overlaping second object (B) to be dropped and at the same time that second object (B) is to be moved to starting position of (A) object automaticaly.
i have 4 objects in line that are dragable only on X axis and when i drag one that he switch places with one next to him.
eg. when street hustler has 3 matchstiks boxes and shuffles them.
