Autoit inside another program

[ShadowIRON 0]

Hello!

I've made a pretty simple script:
 

#include <Constants.au3>
#include <Misc.au3>


Local $hDLL = DllOpen("user32.dll")

While 1
    If _IsPressed("46", $hDLL) Then

        ; Wait until key is released.
        While _IsPressed("46", $hDLL)
           Send("{S 2}")
            Sleep(250)
        WEnd
    ElseIf _IsPressed("1B", $hDLL) Then
        ExitLoop
    EndIf
    Sleep(250)
WEnd

DllClose($hDLL)

All its supposed to do press S 2 times every 250ms while i'm holding down the 'F' key.
It is working properly,however it doesn't run under another program.
I wanna start a project where i can clear certain levels in games. I'm trying with Dark souls 3 atm, and the script seems like "not running" while im inside the game, however if i press alt+tab and go into a notepad or something and i press 'F' it still works. Is there any solution for that? Or should i just try with other games?
