Hi all. I want to use my joystick as a gear shifter for a racing game. I have already compiled the joystick script in AutoHotKey Help. It gives me a popup box displaying the percent of joystick x,y axis. I am using these numbers in the logic below.

Ok. Now, Here is my script:

#Persistent ; Keep this script running until the user explicitly exits it.
SetTimer, WatchAxis, 5
return

WatchAxis:
GetKeyState, JoyX, JoyX ; Get position of X axis.
GetKeyState, JoyY, JoyY ; Get position of Y axis.
KeyToHoldDownPrev = %KeyToHoldDown% ; Prev now holds the key that was down before

(if any).

if (JoyX < 1)and(JoyY < 1)
{
KeyToHoldDown = Numpad7
}
if (JoyX = 37)and(JoyY < 1)
{
KeyToHoldDown = Numpad8
}
if JoyY = 87
{
KeyToHoldDown = Numpad2
}
if JoyY = 42
{
KeyToHoldDown = Numpad6
}
if JoyY = 85
{
KeyToHoldDown = Numpad3
}
else KeyToHoldDown =

if KeyToHoldDown = %KeyToHoldDownPrev% ; The correct key is already down (or no key

is needed).
return ; Do nothing.

; Otherwise, release the previous key and press down the new key:
SetKeyDelay -1 ; Avoid delays between keystrokes.
if KeyToHoldDownPrev ; There is a previous key to release.
Send, {%KeyToHoldDownPrev% up} ; Release it.
if KeyToHoldDown ; There is a key to press down.
Send, {%KeyToHoldDown% down} ; Press it down.
return

This code will not work properly and I have no idea why. Can anyone help me?

In the scheme of things, are you trying to do a layout of the traditional H pattern, or is it more or less a push up to shift up down to shift down type of thing?

Either way, you can use the same type of logic defined for one to use for the other, just the complexity grows as does the number of "gears" involved in your project.

This can be done a number of ways. However, I think it would be in your best interest to do a map to calibrate the joystick. Find the range of it's parameters, just to gain a relative referencepoint.

You're thinking about this pretty linearly, from what I can see anyways, while also not taking into account the variance needed. Joysticks aren't perfect, which is why I said you should REALLY be sure of the position that you're using.

The way to sort through this is through nested IF statements. But before you can do that, it's better to get the logic straight on the problem. This is how I would do it.
