Getting when a player has stopped moving help?

So I'm trying to get it so when the player stops moving, they can regain control of their player and continue actions fluidly, I tried doing repeat wait() until character.Humanoid.Running == false but for obvious reasons, that didn't work

repeat wait() until game.Players.LocalPlayer.Character
local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:wait()
local torso = character.Torso
local walls = game.Workspace.Walls:GetChildren()

function onKeyPress(inputObject, gameProcessedEvent)
    if inputObject.KeyCode == Enum.KeyCode.E then
        local lowest = 20
        local low
        local mag
        for _, wall in pairs(walls) do
            local distance = (torso.Position - wall.Position).magnitude
            mag = distance
            if distance < lowest then 
                lowest = distance
                low = wall
            end
        end
        print(low)
        if low then
            local ray = Ray.new(torso.Position, (low.Position - torso.Position).unit * 999)
            local hit, position = game.Workspace:FindPartOnRay(ray, character)
            local distance = (position - torso.Position).magnitude
            local rayPart = Instance.new("Part", player.Character)
            rayPart.Name = "RayPart"
            rayPart.BrickColor = BrickColor.new("White")
            rayPart.Transparency = 0.5
            rayPart.Anchored = true
            rayPart.CanCollide = false
            rayPart.TopSurface = Enum.SurfaceType.Smooth
            rayPart.BottomSurface = Enum.SurfaceType.Smooth
            rayPart.formFactor = Enum.FormFactor.Custom
            rayPart.Size = Vector3.new(0.2, 0.2, distance)
            rayPart.CFrame = CFrame.new(position, torso.Position) * CFrame.new(0, 0, -distance/2)
            coroutine.wrap(function()
                wait(.5)
                rayPart:Destroy()
            end)()
            --here is where I need help
            player.PlayerScripts.ControlScript.Disabled = true
            player.Character.Humanoid.WalkToPoint = position
            player.Character.Humanoid.WalkSpeed = 23
            repeat wait() until character.Humanoid.Running == false
            player.Character.Humanoid.WalkSpeed = 16
            player.PlayerScripts.ControlScript.Disabled = false
            --
        end
    end
end

game:GetService("UserInputService").InputBegan:connect(onKeyPress)
