How would i make this go smoother than it initially is?

#Smoothening.

I'm completely aware of tweening and lerping but i don't really know how to do it in this situation.

The script is working 100% well, but i just want it to be smoother;

#SCRIPT

local Player = game.Players.LocalPlayer
local Character = Player.CharacterAdded:wait() ; Character = Player.Character
	local Torso = Character:WaitForChild'Torso'
	local Neck = Torso:WaitForChild("Neck")
	 
	local Humanoid = Character:WaitForChild("Humanoid")
	Humanoid.AutoRotate = false
	local HMR = Character:WaitForChild("HumanoidRootPart")
	 
	local Mouse = Player:GetMouse()
	 
	local RC0 = CFrame.new(1, .5, 0, 0, 0, 1, 0, 1, 0, -1, 0, 0)
	local RC1 = CFrame.new(-.5, .5, 0, 0, 0, 1, 0, 1, 0, -1, 0, 0)
	 
	local LC0 = CFrame.new(-1, .5, 0, 0, 0, -1, 0, 1, 0, 1, 0, 0)
	local LC1 = CFrame.new(.5, .5, 0, 0, 0, -1, 0, 1, 0, 1, 0, 0)
	 
	local NeckC0 = Neck.C0
	local NeckC1 = Neck.C1
	 
	while wait(1) do
	    local cf = workspace.CurrentCamera.CFrame.lookVector.Y
	 
	    Neck.C0 = NeckC0 * CFrame.Angles(math.asin(Mouse.Origin.lookVector.Y), 0, 0):inverse()
	    HMR.CFrame = CFrame.new(HMR.Position, Vector3.new(Mouse.Hit.p.x, HMR.Position.Y,Mouse.Hit.p.z))
	end

If this is a ServerScript, you can use RunService's Stepped event, that fires every frame prior to the physics simulation.

while game:GetService("RunService").Stepped:wait() do
	--// Rest of code
end

OR - The code is the same, just formatted differently.

local RS = game:GetService("RunService")

while RS.Stepped:wait() do
	--// Rest of code
end

If this is a LocalScript, you can use the same thing, except using RenderStepped instead of Stepped. This fires every frame prior to the frame being rendered.

while game:GetService("RunService").RenderStepped:wait() do
	--// Rest of code
end

OR - The code is the same, just formatted differently.

local RS = game:GetService("RunService")

while RS.RenderStepped:wait() do
	--// Rest of code
end

Either way, these will be fired every frame.

• RenderStepped can only be called in a LocalScript.

• Stepped can only be called in a ServerScript.

(You could use RunService.Heartbeat:wait(), which can only be used in a LocalScript, but I'd use RenderStepped over Heartbeat)

Hope this helped! Feel free to select this as an answer if this worked for you!
