The character is walking at left and I want him to look right while he is doing that.

Here is my script :

local player = game.Players.LocalPlayer
local RunService = game:GetService("RunService")
local ContextActionService = game:GetService("ContextActionService")
local char = player.Character or player.CharacterAdded:wait()
local hum = char:WaitForChild("Humanoid")

local jumping = false
local leftValue, rightValue = 0,0
local lastDirection, currentDirection = 0, 0

local AnimationTrack

local function playerOrient(angle)
	if lastDirection~=currentDirection then
		local HRP = player.Character:WaitForChild("HumanoidRootPart")
		local Rootjoint = player.Character.Torso:WaitForChild("Neck")
		local x, y, z = HRP.CFrame:ToEulerAnglesYXZ()
		HRP.CFrame = CFrame.new(HRP.Position) * CFrame.Angles(0, angle, 0)
	end
end

local function onLeft(actionName, inputState)
	if inputState == Enum.UserInputState.Begin then
		local animation = Instance.new("Animation")
		local animationId = 10927684449 
		animation.AnimationId = "rbxassetid://" ..animationId
		AnimationTrack = hum:LoadAnimation(animation)
		AnimationTrack:Play(0.100000001, 1, -1)
		leftValue = 1
		currentDirection = -1
		playerOrient(math.rad(90))
		lastDirection = -1
	elseif inputState == Enum.UserInputState.End then
		AnimationTrack:Stop()
		leftValue = 0
	end
end

local function onRight(actionName, inputState)
	if inputState == Enum.UserInputState.Begin then
		rightValue = 1
		currentDirection = 1
		playerOrient(math.rad(270))
		lastDirection = 1
	elseif inputState == Enum.UserInputState.End then
		rightValue = 0
	end
end

local function onJump(actionName, inputState)
	if inputState == Enum.UserInputState.Begin then
		jumping = true
	elseif inputState == Enum.UserInputState.End then
		jumping = false
	end
end

local function onUpdate()
	if player.Character and player.Character:FindFirstChild("Humanoid") then
		if jumping then
			player.Character.Humanoid.Jump = true
		end
		local moveDirection = rightValue - leftValue
		player.Character.Humanoid:Move(Vector3.new(moveDirection,0,0), false)
	end
end

RunService:BindToRenderStep("Control", Enum.RenderPriority.Input.Value, onUpdate)

ContextActionService:BindAction("Left", onLeft, true, Enum.KeyCode.A, Enum.KeyCode.Left, Enum.KeyCode.DPadLeft)
ContextActionService:BindAction("Right", onRight, true, Enum.KeyCode.D, Enum.KeyCode.Right, Enum.KeyCode.DPadRight)
ContextActionService:BindAction("Jump", onJump, true, Enum.KeyCode.W, Enum.KeyCode.Space, Enum.KeyCode.Up, Enum.KeyCode.DPadUp)
