Does anyone know where I can go from walk animation??

so this is a walking animation from a npc and i dont know where i should go from here I already made an animation that walks but i dont know what to do at the humanoid.running event

so far this is my script but its kinda messy and broken because if the event does not fire idk tbh he always fidgets cause event fires too fast sometimes

Ths means that if the run event does not fire the animation does not play

TestingDummie = script.Parent
Humanoid = TestingDummie.TestingDummy
Loading = Humanoid:LoadAnimation(script.Animation)
Loading.Looped = true
wait(1)


Humanoid.Running:Connect(function()
        print('The thing walk lmao')
        Loading:Play()



end)
