I am stuck on how i can make this part velocity move to mouse position, can someone lead insight?

Ive been stuck on how i can make the part move using mouse to use body velocity to move it

local BV = Instance.new("BodyVelocity",WaterDragon)

BV.MaxForce = Vector3.new(math.huge,math.huge,math.huge)

while WaterDragon do local MousePosition2 = Character.GetMouse:InvokeClient(Player) BV.Velocity = Vector3.new(MousePosition2) end

doesnt do squat.
