Character is pushed forwards whilst strafing

[LordVoidron (Voidron)]

So I’m having an odd issue concerning the players movement.
Whenever the player strafes perpendicular to their facing direction, they are slowly moved forwards.

The problem only exists under the two conditions:

• The model type is R6
• There are walking and running animations

So the question is why does the walk/run animation cause this, and how can I fix it. I have messed with it for a bit and am wondering if anyone else has any solutions.

If you wish to replicate this issue; Put the following code in a local script in either StarterCharacterScripts or StarterPlayerScripts and have the model types be set to R6.

local runService = game:GetService("RunService")
local CAS = game:GetService("ContextActionService")

local Aimlocked = false
local function AimlockHotkey(ActionName,State)
	if State == Enum.UserInputState.Begin then
		Aimlocked = not Aimlocked
	end
end

local function Aimlock()
	local Character = game.Players.LocalPlayer.Character or game.Players.LocalPlayer.CharacterAdded:Wait()
	local humanoid:Humanoid = Character:FindFirstChild("Humanoid")
	if not Aimlocked then
		humanoid.AutoRotate = true
		return	
	end
	local Mouse = game.Players.LocalPlayer:GetMouse()
	local CharacterPart = Character.PrimaryPart
	humanoid.AutoRotate = false
	CharacterPart.CFrame = CFrame.new(CharacterPart.Position, Vector3.new(Mouse.Hit.X, CharacterPart.Position.Y, Mouse.Hit.Z))
end
CAS:BindAction("AimlockToggle",AimlockHotkey,false,Enum.KeyCode.LeftShift)
runService:BindToRenderStep("character",Enum.RenderPriority.Character.Value,Aimlock)

(If you do not disable shiftlock or have it enabled in game settings you might want to change the keycode for the Context Action Service at the bottom)

i believe its fixed if you convert it to use alignoriention rather than natively change the cframe of the char

local runService = game:GetService("RunService")
local CAS = game:GetService("ContextActionService")

local Aimlocked = false
local AlignOrientation = nil

local function AimlockHotkey(ActionName, State)
	if State == Enum.UserInputState.Begin then
		Aimlocked = not Aimlocked

		local Character = game.Players.LocalPlayer.Character or game.Players.LocalPlayer.CharacterAdded:Wait()
		local humanoid:Humanoid = Character:FindFirstChild("Humanoid")
		local CharacterPart = Character.PrimaryPart

		if Aimlocked then
			if not AlignOrientation then
				AlignOrientation = Instance.new("AlignOrientation")
				AlignOrientation.Mode = Enum.OrientationAlignmentMode.OneAttachment
				AlignOrientation.RigidityEnabled = true
				AlignOrientation.Attachment0 = CharacterPart:FindFirstChild("RootAttachment") or Instance.new("Attachment", CharacterPart)
				AlignOrientation.Parent = CharacterPart
			end
			humanoid.AutoRotate = false
		else
			if AlignOrientation then
				AlignOrientation:Destroy()
				AlignOrientation = nil
			end
			humanoid.AutoRotate = true
		end
	end
end

local function Aimlock()
	if not Aimlocked then
		return
	end
	local Character = game.Players.LocalPlayer.Character or game.Players.LocalPlayer.CharacterAdded:Wait()
	local Mouse = game.Players.LocalPlayer:GetMouse()
	local CharacterPart = Character.PrimaryPart
	local targetPos = Vector3.new(Mouse.Hit.X, CharacterPart.Position.Y, Mouse.Hit.Z)
	local lookAt = CFrame.lookAt(CharacterPart.Position, targetPos)

	if AlignOrientation then
		AlignOrientation.CFrame = lookAt
	end
end

CAS:BindAction("AimlockToggle", AimlockHotkey, false, Enum.KeyCode.LeftShift)
runService:BindToRenderStep("character", Enum.RenderPriority.Character.Value, Aimlock)

Thanks, this works perfectly.

Though I am still somewhat confused as to what engine jank caused the issue before.
