How to force Player to Look at a part?

I search everywhere for solution , but none is working.

Have you ever play a fighting game ? Dragon ball is a great example , when you press 'Q' the Player 'Lock Look' or 'Target' a specific Enemy,so when ever you move or the target move , the Player will continuously look at the target.

I believe I can use BodyForce , but not CFrame. I tried CFrame.This is my Script.

local Player = game.Players.LocalPlayer
repeat wait() until game.Workspace:FindFirstChild(Player.Name)
local Character = game.Workspace[Player.Name]

while true do
    wait()
Player.Character.HumanoidRootPart.CFrame =   
   CFrame.new(Player.Character.HumanoidRootPart.Position , 
      game.Workspace.Dummy.HumanoidRootPart.Position)

end

I Created a CFrame.new(Player Position , Target Position )

The Result is a failure , you can try my script yourself XD

Back to the question , you guys have any ideas how to do it?
