Problem with adding directional bodyvel

Hello, im trying to make ODM gear in AOT kind of like this: https://twitter.com/returnedbydeath/status/1612206224140910592 3

However, im having trouble in making the player go/tilt to the left/right when pressing A or D, here is my code:

-- Variables
local boostSpeed = 100
local player = game.Players.LocalPlayer
local character = workspace:WaitForChild(player.Name)
local HRP = character.HumanoidRootPart
local CurrentERope = nil
local EConnections = {}
local UIS = game:GetService("UserInputService")
local RS = game:GetService("RunService")
local moveSpeed = 200 
local IsTiltingA = false
local IsTiltingD = false
--Fired when pressing/unpressing A or D
local function movePlayer(direction)
	if CurrentERope then 
		local movementDirection = direction * moveSpeed
		local velocity = Vector3.new(movementDirection.X, 0, movementDirection.Z)
		CurrentERope.Velocity = CurrentERope.Velocity+velocity
	end
end

local function SubtractVelocity(direction)
	if CurrentERope then 
		local movementDirection = direction * moveSpeed
		local velocity = Vector3.new(movementDirection.X, 0, movementDirection.Z)
		CurrentERope.Velocity = CurrentERope.Velocity-velocity
	end
end
--Fired when pressing E
      local mPos = player:GetMouse().Hit.Position
      local bv = Instance.new("BodyVelocity", HRP)
      CurrentERope = bv
      bv.MaxForce = Vector3.one * math.huge
      bv.P = math.huge
      bv.velocity = (mPos - HRP.Position).Unit * boostSpeed
         -- Updating BV.
	local conn = RS.Heartbeat:Connect(function(deltaTime)
	      bv.velocity = (mPos - HRP.Position).Unit * boostSpeed
	      if IsTiltingA then
	      local movementDirection = Vector3.new(-1, 0, 0) * moveSpeed
	      local velocity = Vector3.new(movementDirection.X, 0, movementDirection.Z)
              CurrentERope.Velocity = CurrentERope.Velocity+velocity
	end
	if IsTiltingD then
		local movementDirection = Vector3.new(1, 0, 0) * moveSpeed
		local velocity = Vector3.new(movementDirection.X, 0, movementDirection.Z)
		CurrentERope.Velocity = CurrentERope.Velocity+velocity
	    end
	print(bv.Velocity)
  end)

table.insert(EConnections, conn)

Heres what it looks like ingame: - YouTube
