How would I go about making a Character BodyGyro?

How would I make it so a BodyGyro, placed into the Character's torso, is pointed toward where the player puts their mouse?

I am guessing it would be something like this...

You would have a localscript inside the player that has the code:

local Player = game.Players.LocalPlayer
local mouse = Player:GetMouse()
local Gyro = script.Parent:FindFirstChild("Torso"):FindFirstChild("BodyGyro")

local CanTurn = true -- A bool value that will be determined that will determine if the character is allowed to turn at this moment in time.

Gyro.Torque = Vector3.new(10000000,10000000,10000000)

if Gyro == true then
while CanTurn == true do
Gyro.cframe = Cframe.new(0,mouse.X,0)
end
end

This is meant to where the player turns their mouse, their character will turn, but they cannot turn upward, so that the fall over.

Will this work?
