Character Spinning when colliding

Help and Feedback Scripting Support

What I want to achieve
I am trying to make the y axis of the rootjoint motor6d match the camera’s y axis so that the player auto rotates parallel with the camera

-As you can see in the video the character is spinning when colliding another part

What solutions have I tried so far?
I have tried making the C0 of the RootJoint match the humanoidrootparts orientation but that didnt really do anything.

–Client code inside of the character (the remote is just the same code just to sync)

local camera = workspace.Camera
local humanoidrootpart = script.Parent.HumanoidRootPart
local remote = game.ReplicatedStorage.Autorotate
game:GetService("RunService").Heartbeat:Connect(function()
	local cframe = camera.CFrame
	local x,y,z = cframe:ToOrientation()
	local orientation = Vector3.new(0,math.deg(y),0)
	remote:FireServer(orientation)
	local rootJoint = humanoidrootpart and humanoidrootpart:FindFirstChild("RootJoint")
	rootJoint.C0 = CFrame.fromOrientation(0, humanoidrootpart.Orientation.Y /-1,0)
	rootJoint.C1 = CFrame.fromOrientation(0,-y,0)
end)

Use AlignOrientation with to avoid that conflict between the script and Roblox collision system
And there is no need constantly fire the orientation to server when using AlignOrientation

remote:FireServer(orientation)

I have already tried this and this issue kept happening so I switched to script based. (Im also using unreliable remote events so it doesn’t mess up performance)

Issue with using physics base auto rotation ^^^

Tried out myself to make that system with AlignOrientation and didn’t get that issue.

Code:


local modelChar = script.Parent

local ao = Instance.new("AlignOrientation", modelChar)
ao.Mode = Enum.OrientationAlignmentMode.OneAttachment
ao.Attachment0 = modelChar.PrimaryPart:FindFirstChildOfClass("Attachment")
ao.Responsiveness = 50

local camera = workspace.CurrentCamera


function NormalizeAngleRad(intAngleRad :number)
	return (intAngleRad+math.pi) % (math.pi*2) - math.pi
end


local function UpdateLook()
	local vec3CameraLook = camera.CFrame.LookVector
	local numRadAngle = -math.atan2(vec3CameraLook.Z, vec3CameraLook.X) - math.pi/2
	local numRadCorrectAngle = numRadAngle
	ao.CFrame = CFrame.Angles(0,numRadCorrectAngle,0)
end

camera:GetPropertyChangedSignal("CFrame"):Connect(UpdateLook)
