Character Rotation

[Complextic]

local lookAtXZ
local newRootCF
function CharacterFaceCamera()
	lookAtXZ = HumanoidRootPart.Position + Vector3.new(Camera.CFrame.LookVector.X, 0, Camera.CFrame.LookVector.Z)
	newRootCF = CFrame.new(HumanoidRootPart.Position, lookAtXZ)

	local tweenInfo = TweenInfo.new(
		0.15,
		Enum.EasingStyle.Sine,
		Enum.EasingDirection.Out,
		0,
		false,
		0
	)
	local tween = TweenService:Create(HumanoidRootPart, tweenInfo, {["CFrame"] = newRootCF})
	tween:Play()
end

RunService:BindToRenderStep("cameraControl", Enum.RenderPriority.Camera.Value, LockCamera)
RunService:BindToRenderStep("characterFaceMouse", Enum.RenderPriority.Character.Value, CharacterFaceCamera)

In my game I have code that will basically point the HumanoidRootPart towards the mouse, but I want the UpperTorso, LowerTorso, Arms, Head to bend and point up and down depending on where the player is aiming but I have no idea how to do this.

I think this by egomoose would help.

Ego is bored: Pitch

It shows some really good practice with cframe and has what to do in order for a body to follow the camera

I think this may be a better fit for the question.

The First Person Element Of A First Person Shooter

This guide was originally written for scriptinghelpers. The original can be found here. In this post we will be talking about creating our very own filtering enabled friendly first person shooter (FPS) game. I do want to make clear though that I won’t be covering how to actually make the weapon shoot in this article. All we are going to be covering is the visuals meaning having the character aim down sights, look up and down, etc. Maybe we’ll talk about shooting another day. Things to take …

It shows how to have the character bend arms torso and head up and down for an FPS, but im sure it would be enough to make work for whatever purposes.

You could try simply bending the UpperTorso and HumanoidRootPart at the same time. Since the arms and Head are all connected to the UpperTorso, I’m pretty sure the arms will move with the UpperTorso, similar to how they move if you’ve ever used Animation Editor.

Oh yap that would be a better suggestion, I didn’t see this one yet time to read it!
