How do I make the player face the same way as the camera without facing up and down?

hey so I want the player to face the same way the camera is faceing so its working just fine but how do I make it to not face in the up and down direction here is what I got

local Camera = workspace. CurrentCamera 
local HumanoidRootPart = game.Players.localPlayer.character.HumanoidRootPart

Camera.Changed:Connect(function(changed)
    HumanoidRootPart.CFrame = CFrame.new(HumanoidRootPart.Position, Camera.CFrame.LookVector  * 100000)
end)
