Npc raycasting doesnt work when it goes side ways?

I have 2 parts that the npc will walk to. But if you put on of the part a little to the right or left from the other part the ray will not check in from of the npc anymore.

How do i fix this and here is the script:

Its inside of the npc

its on line 7-11

local guard = script.Parent
local target


--Vector3.new(guard.HumanoidRootPart.CFrame.lookVector.X).Unit*50

while true do
		local ray = Ray.new(guard.HumanoidRootPart.CFrame.p,(Vector3.new(guard.HumanoidRootPart.CFrame.lookVector.x,guard.HumanoidRootPart.CFrame.lookVector.y,0) * Vector3.new(guard.HumanoidRootPart.CFrame.X+100,0,guard.HumanoidRootPart.CFrame.Z+100)).unit * 25)
		local part, position = workspace:FindPartOnRay(ray, guard, false, true)
 
		local beam = Instance.new("Part", workspace)
		beam.BrickColor = BrickColor.new("Bright red")
		beam.FormFactor = "Custom"
		beam.Material = "Neon"
		beam.Transparency = 0.25
		beam.Anchored = true
		beam.Locked = true
		beam.CanCollide = false
 
		local distance = (guard.HumanoidRootPart.CFrame.p - position).magnitude
		beam.Size = Vector3.new(0.1, 0.1, distance)
		beam.CFrame = CFrame.new(guard.HumanoidRootPart.CFrame.p, position) * CFrame.new(0, 0, -distance / 2)
 
		game:GetService("Debris"):AddItem(beam, 0.1)
		if part then
			if part.Parent:FindFirstChild("Humanoid") and game.Players:FindFirstChild(part.Parent.Name) then
				--print("FOUND A PLAYER! "..guard.Name)
				guard.MovementScript.Disabled = true
				guard.Humanoid:MoveTo(part.Parent.HumanoidRootPart.Position+ Vector3.new(0,0,2))
				game.Players:FindFirstChild(part.Parent.Name).leaderstats.attension.Value = game.Players:FindFirstChild(part.Parent.Name).leaderstats.attension.Value+1
				if game.Players:FindFirstChild(part.Parent.Name).leaderstats.attension.Value >= 100 then
					target = part.Parent
				end
			else
				wait(.3)
				guard.MovementScript.Disabled = false
			end
		end
	if target ~= nil then
		if workspace:FindFirstChild(target.Name) then
			guard.Humanoid:MoveTo(target.HumanoidRootPart.Position)
		end
	end
	wait()
end

Please make a comment if you didnt understand the parts and why it didn't work.
