Custom head movement isnt working?

Help and Feedback Scripting Support
#1

hello devs!, I’m reaching out to ask for help because I’ve hit a roadblock. I’m aware of the possibility I haven’t set it up right and hoping its not a code error as it was working before I finalized it. ive tried an assortment of things and have been unsuccessful. this is what it all looks like in workspace.

here is the code im using
headmovement

local tweenService = game:GetService("TweenService")

local Camera = workspace.CurrentCamera
local Player = game.Players.LocalPlayer

local Character = Player.Character
local Root = Character:WaitForChild("HumanoidRootPart")
local Neck = Character:FindFirstChild("Neck", true)
local YOffset = Neck.C0.Y

local CFNew, CFAng = CFrame.new, CFrame.Angles
local asin = math.asin

game:GetService("RunService").RenderStepped:Connect(function()
	local CameraDirection = Root.CFrame:toObjectSpace(Camera.CFrame).lookVector
	if Neck then
		if Character.Humanoid.RigType == Enum.HumanoidRigType.R15 then
			Neck.C0 = CFNew(0, YOffset, 0) * CFAng(0, -asin(CameraDirection.x), 0) * CFAng(asin(CameraDirection.y), 0, 0)
		elseif Character.Humanoid.RigType == Enum.HumanoidRigType.R6 then
			Neck.C0 = CFNew(0, YOffset, 0) * CFAng(3 * math.pi/2, 0, math.pi) * CFAng(0, 0, -asin(CameraDirection.x)) * CFAng(-asin(CameraDirection.y), 0, 0)
		end
	end
end)

	local Neck = otherPlayer.Character:FindFirstChild("Neck", true)
	Neck.C0 = neckCFrame
end)

So if the issue is that the head movement isn’t that smooth well, it could be because using CFrame lookat methods on the player’s character is not that smooth usually. It’s better to use something like bodygyros or alignorientation, much smoother.

a little update i moved it around it all works properly i just cant look around after i start moving!

to be honest im not quite sure how that could be a issue though because it was working perfectly beforehand!

Oh, that’s strange then? Whenever I tried to use methods of head movement they were jittery without constraints like bodygyros or align orientation haha.

Um what is Head? Are you sure it actually exists? It could be because of the movement you made that as soon as you move it sorta flings itself out or something.

now that you mention it im not entirely sure… should i have it look in the players tab?

Yeah possibly. Maybe add a waitforchild actually if your code is running on the client, pretty sure it is due to the renderstepped.

By waitforchild I mean you know, :WaitForChild(“Head”). I think you know waht I mean.

i sort of understand my friend has been teaching me code im still id say decently new to it but this is one of the most advanced thing ive done

Oh alright, yeah basically waitforchild will basically yield the script until it finds the child of what you inserted. So it’s less likely for you to run into an error where something doesn’t exist yet. People use waitforchild alot on the client because sometimes things haven’t loaded in yet. As alot of the stuff from the server is replicated to the client.

Yield is just a fancy way of saying like pause. It just pauses the script at the line where you called waitforchild and doesn’t go any lower than that until it finds the child.

i added it and it works a little more responsive but i dont think it actually move the head and it also stops when i click onto the screen to move around heres a link to a clip i took of it script - Clipped with Medal.tv
