mmm nobody are answering to you. 🙁
Aim Mode (battlefield and similar FPS,not for csgo) :
is related to your option in game “weapon Zoom”
so if you have Hold (means that you hold down the right button mouse)
you have to select hold in MSE.
if in game you have “pressed” (means that you press once time the right button to aim and press again to toggle it)
you have to select pressed in MSE, and in this case you have to press , when zoomed, the left shift key or the aim key selected.
about the smooth bar just set 0% first time and later set 100% to understand how it works.
if you need more support we can make a connection using ultraviewer, for example, to solve any doubts.
let me know if you got it.
