UID-Based Drag & Drop Flow for Multi-Instance Objects

I place my sunglasses Sprite in three different places.

Step 1: I can drag one pair of sunglasses to a specific object, and then I can make a new ice cream thing. 

Note that the other two pairs of sunglasses cannot drag.

Step 2: I can drag and drop the ice cream into the   new created icecream  area.

NOte in My project i have only one sunglass and icream images

how to achieve in evensheet?

“Same here, I’m a bit confused too. KG Baran, do you mean you want only one sunglasses instance draggable at a time, and the others locked? Or are you trying to spawn a new ice cream object when you drop the sunglasses somewhere? Maybe explaining your end goal step by step would help.”

Maybe they are trying to make a merge game? And whatever they tried only works for one instance based on the “note”.

We are missing information.
