[Closed] ID based skinwrap

I am trying to make an object follow the deformation of another exact copy of itself like skinwrap but not based on distance instead on vertex id

I am not sure what to do or even if it is doable.
My try(modified from another script):

plugin simpleMod ID_Deform
name:"ID_Deform"
classID:#(0x488f34ee, 0x28ce49d3)
version:1
(
	local obj = $
	
	parameters main rollout:params
	(
		PickedObj type:#node ui:btn1
	)
		rollout params "Parameters" width:162 height:142
	(
		fn meshTypeObj PickedObj = classof PickedObj == Editable_mesh or classof PickedObj == Editable_poly
			
		pickbutton btn3 "Pick Mesh" pos:[29,34] width:103 height:22 filter:meshTypeObj

		on btn1 picked PickedObj do
		(
			PickedObj=btn3.object
			update obj
		)
		
	)
 
	fn copypos obj1 obj2 = 
	(
		--vertnum=obj1.verts.count
		--for i =1 to vertnum do	
		--obj1.verts[1].pos =obj2.verts[1].pos
		
		
		vpos=obj2.verts[1].pos
		polyop.setVert obj1.modifiers[1] 1 vpos node:$
	)
	
	on map i p do
		(
			if PickedObj != undefined and isValidNode PickedObj do
			(
				p=copypos $ PickedObj
				--p=PickedObj.verts[i].pos
			)
			p
		)

)
