I heard something called run service before but I don't rly know how to use it.
I know it consist of delta time and change in rate and Frames but I don't know what you could use this technique on.
could you use it to script a sword or a growing part (meaning for I = 1,10 do part.Size = Part.Size + Vector3.new(0,2,0) ?
