Need Help with touch controls

[mihnea2kx]

There is a snapshot in the attachment . All the coins have a boxcollider, a button script and a tween position script to move on the screen . I want to drag one coin over another and access both the coins properties . I tried using OnDragStart() , OnPress(bool isPressed) but no luck .
Any help would be appreciated .

Only the top-most object will receive events. This is why when dragging something, NGUI's drag & drop scripts happen to disable the dragged object. This way it doesn't eat up all events and it becomes possible for objects underneath it to receive OnDragOver / OnDragOut.
