How Do I Make A Certain Function Reset Before Finishing After The Mouse.Target Has Changed? Heres The Script Just Incase:

local replicatedstorage = game:GetService("ReplicatedStorage") 
     
                 local run = game:GetService("RunService")
  local Player = game.Players.LocalPlayer
                                        local mouse = Player:GetMouse()
          local billBG = replicatedstorage:WaitForChild("BlockTag") 
                                                                     local down

run.RenderStepped:Connect(function()
	if mouse.Target ~= nil then
		if mouse.Target.Parent == game.Workspace.Blocks then
			billBG.Parent = mouse.Target
			print("BlockHoveredOn!")
		else
				billBG.Parent = replicatedstorage
				print("No Destroy-Able Blocks Found")
				wait(1)
		end
	end
	
	mouse.Button1Down:Connect(function()
		down = true
		
	  for _,child in pairs(billBG:GetChildren()) do
		child.Visible = true
	end
		
		
		
	end)
	------------------------------------------------------------------------- ...
	mouse.Button1Up:Connect(function()
		down = false
		
	  for _,child in pairs(billBG:GetChildren()) do
		child.Visible = false
	end
		
		
		
	end)
	 while down do
		wait(0.01)
		while mouse.Target do
			wait(0.0001)
			  if mouse.Target.Parent == game.Workspace.Blocks then
			wait(2)
		mouse.Target:Destroy()
		 
		end
		end
