How to make the hand n head follow cursur while the hand is holding a hammer in 2D?

HI! I've tried many ways to do the script like creating my own or search it online and download it but non of them work, I even edit the script. Can someone show me the script that make the head and hand follow the cursur while the hand is holding a hammer in 2D just like the game Getting Over It?

function torsoPoint()
	local torso = player.Character.HumanoidRootPart
	if equip and tool then
		local direction = (mouse.Hit.p - torso.Position) * Vector3.new(1, 0, 1)
    		torso.CFrame = CFrame.new(torso.Position, torso.Position + direction)
	end
end

This will make the torso point at the mouse position.
