Need help with torso and head following mouse

reygenne1 · October 12, 2020, 1:19pm

It doesn’t, it contains the waist motor6d which the torso doesn’t contain.

Can you please, in depth, explain how the code works? I know some basics of coding, but I don’t know globals (such as workspace) in your code, or what the Neck and Waist C0 lerp is doing. Since there are no YouTube tutorials on this topic (that I know of), and I need to ask you so I can understand how to make the character move that smoothly.

Would this go inside a LocalScript in StaryerPlayerScripts?

matyas095 · December 27, 2020, 6:58pm

Yeah this is Client-Sided code, you’ll need to place it in LocalScript and you need to place it in StarterCharacterScripts.

How could I possibly make this server-sided?

Anurag_UdayS · February 7, 2021, 12:06pm

Hey! How are you doing? I was looking at the script given by @CleverSource and I noticed your reply. I also needed to make the event server-sided and after playing around a bit, I got the way to make the script server-sided. So, let me explain you how to make the script server-sided.

What you'll have to do:

Make two RemoteEvents via the server-script. - One for getting the client's player and the other for getting the client-sided function. Ensure that the Parents and Names of the RemoteEvents are correctly declared.
Declare the constant data in the server-script. - Create empty variables for the purpose.
Go to the LocalScript and WaitFor the RemoteEvents.
Declare the client data on the local script. - This is the data that the server-script cannot handle. Fire the client's player-yielding RemoteEvent. - The alternate way to do this is to use
```
game:GetService("Players").PlayerAdded:Connect(function(player) --[[The content of the script]]-- end)
```
Assign the values of the constant data declared above.
Declare the variable values inside the client-sided function script. - This is done because this data is the main doer of the function.
Fire the client-sided function script. - Here, I've used
```
game:GetService("RunService").RenderStepped:(function() --[[Firing the Server]]-- end)
```
- RunService cannot be fired on server-script.
Call the function shown by @CleverSource inside the OnServerEvent connection.

And then you have it! you have successfully server-sided the script. For reference, I’ll add in the LocalScript and the Script.
Note: Some of the variables and constants have been removed from @CleverSource’s code, as that data was unused.

Local Script:

--------------------------------------------------------------------- local GetLocalData = game:GetService("ReplicatedStorage"):WaitForChild("GetLocalData") local GetMouseFollowFunction = game:GetService("ReplicatedStorage"):WaitForChild("GetMouseFollowFunction") --(iii) --------------------------------------------------------------------- local CameraSubject = workspace.CurrentCamera.CameraSubject -- (iv) GetLocalData:FireServer()-- (v) RunService.RenderStepped:Connect(function() local PlayerMouseHit = game.Players.LocalPlayer:GetMouse().Hit.p -- (vii) GetMouseFollowFunction:FireServer(CameraSubject,PlayerMouseHit) -- (viii) end)

Note: This is to be put in StarterCharacterScripts.

Server Script:

local GetLocalData = Instance.new("RemoteEvent")
local GetMouseFollowFunction = Instance.new("RemoteEvent")

GetLocalData.Name = "GetLocalData"
GetLocalData.Parent = game:GetService("ReplicatedStorage")

GetMouseFollowFunction.Name = "GetMouseFollowFunction"
GetMouseFollowFunction.Parent = game:GetService("ReplicatedStorage")
-- (i)
---------------------------------------------------------------------

local Character
local Head
local Neck

local Torso
local Waist

local WaistOriginC0
local NeckOriginC0

-- (ii)
---------------------------------------------------------------------

GetLocalData.OnServerEvent:Connect(function(Player)

	Character = Player.Character or Player.CharacterAdded:Wait()
	Head = Character:WaitForChild("Head")
	Neck = Head:WaitForChild("Neck")

	Torso = Character:WaitForChild("UpperTorso")
	Waist = Torso:WaitForChild("Waist")
	
	WaistOriginC0 = Waist.C0
	NeckOriginC0 = Neck.C0
	
	Neck.MaxVelocity = 1/3
end)
-- (vi) 
---------------------------------------------------------------------


GetMouseFollowFunction.OnServerEvent:Connect(function(_,CameraSubject,PlayerMouseHit)
	if Character:FindFirstChild("UpperTorso") and Character:FindFirstChild("Head") then
		local TorsoLookVector = Torso.CFrame.lookVector
		local HeadPosition = Head.CFrame.p

		if Neck and Waist then
			if CameraSubject:IsDescendantOf(Character) or CameraSubject:IsDescendantOf(Player) then
				local Point = PlayerMouseHit

				local Distance = (Head.CFrame.p - Point).magnitude
				local Difference = Head.CFrame.Y - Point.Y

				Neck.C0 = Neck.C0:lerp(NeckOriginC0 * CFrame.Angles(-(math.atan(Difference / Distance) * 0.5), (((HeadPosition - Point).Unit):Cross(TorsoLookVector)).Y * 1, 0), 0.5 / 2)
				Waist.C0 = Waist.C0:lerp(WaistOriginC0 * CFrame.Angles(-(math.atan(Difference / Distance) * 0.5), (((HeadPosition - Point).Unit):Cross(TorsoLookVector)).Y * 0.5, 0), 0.5 / 2)
			end
		end
	end	
end)

Thanks for reading. If this helps, kindly leave a like.

How would i do this for arms, on the y axis only?

MagictheTragic · February 9, 2021, 4:41pm

Hm, something in the script is giving me this error, I truly appreciate your assistance and help!

Anurag_UdayS · February 9, 2021, 4:50pm

It says that your Remote Event is not invoking. Can you show me the server script that you are using?

I changed up the RemoteEvent since it’s in ReplicatedStorage inside of a folder named “General”.

Anurag_UdayS · February 9, 2021, 5:08pm

The error shown in the picture does not show up im my device. Kindly check for any syntax errors.

MagictheTragic · February 9, 2021, 5:10pm

Oh wait, I created 2 RemoteEvents in the RS in a folder and created 2 extra ones in the script. That’s probably why.

MagictheTragic · February 9, 2021, 5:12pm

And now it’s spamming this error:

Referencing line 49:

if CameraSubject:IsDescendantOf(Character) or CameraSubject:IsDescendantOf(Player)

Anurag_UdayS · February 9, 2021, 5:17pm

Can you tell me the value of the CameraSubject?

MagictheTragic · February 9, 2021, 5:21pm

Not sure how to find it, but also forgot to note that Player is underlined red in the code.

Anurag_UdayS · February 9, 2021, 5:25pm

You can try adding a constant for player, then getting the value in the getLocalData function . See if that helps. But the error shows CameraSubject is missing so you will have to get that.

MagictheTragic · February 9, 2021, 6:09pm

Is this what you’re looking for? In that case, it’s humanoid.

Anurag_UdayS · February 10, 2021, 1:30am

Can you try adding print(CameraSubject) after local HeadPosition? I’ll get a better understanding of the issue if I see whether the CameraSubject is firing.

MagictheTragic · February 10, 2021, 1:36am

This is what it prints.
