Hello all. Im very new to this and im trying to to AHK to configure controls for games I have in steam so that they work better with my X-Arcade tank stick which uses a keyboard layout to represent controls on the joysticks. Ive tried using AHK to make edits to controls and run a simple script but so far on the three games ive tried to script for all it does is disable both the origional key and scripted key when I run it. He is an example of one of my scripts

#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
; #Warn ; Enable warnings to assist with detecting common errors.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.
