-- local script
local m = game:GetService("Players").LocalPlayer:GetMouse() -- get the player, and get the players mouse (YOU)
local activ = false -- if the tool is activated

script.Parent.Activated:Connect(function() -- activation trigger
    activ = true -- activated = true
    while task.wait() do -- while activated
        if activ then
            local direction = (m.Hit.p - script.Parent.Parent.HumanoidRootPart.Position) * Vector3.new(1, 0, 1)
            script.Parent.Parent.HumanoidRootPart.CFrame = CFrame.new(script.Parent.Parent.HumanoidRootPart.Position, script.Parent.Parent.HumanoidRootPart.Position + direction) -- root will follow the mouse
            script.Parent.RemoteEvent:FireServer(m.Hit) -- fire the remote
        else break
        end
    end
end)

script.Parent.Deactivated:Connect(function() -- deactivate and stop the loop
    activ = false
end)
