How to set the rootpart to the player who use this move?

how to set the rootpart to the player who use this move? i made a script that a player use a move and when the move hitted i give both of the player local script

this is the local script

local player = game.Players.LocalPlayer.Character


local rootPart = player.PrimaryPart 
local camera = workspace.CurrentCamera 

and this is the attack script

	local cutscene = script.LocalScript:Clone()
							cutscene.Parent = Player.Backpack

and i put it inside the enemy backpack it show enemy itself but not the the user who use this move
