Hello, Trying to add rapid fire to a button on an Xbox controller, but its not working properly and info is really scarce.
In the below table, i was assuming that X button was boolean and 1 means the key is pressed down.
But using 0 or 1 does the same thing, it constantly repeats even when the button is not pushed ?
Any ideas would be appreciated.

GAMEPAD_X is a boolean value, not a number.
so, use only true or false.

Hello mgr.inz.Player, Its good to see you, it seemed liked you had dissapeared for a little while.
Thank you responding, i tried what you said, now the button just functions normally, any ideas ?

Did you test your idea without CE? Does clicking left mouse button while xbox controller X button is pressed works at all, your game allows that?

If yes, then maybe this will work for you, complete AA script:

Thank you again mgr.inz.Player for replying.
Unfortunately that does not work either.
With no scripts enabled if i hold down x on the controller mouse 1 does not work. they are the same function (attack button)
So i also tested the script below in a few variations, but that's not working either.
What i was trying to do is make the x button on the controller rapid fire,

In that case you will have to find an address in game process memory which changes its value when you press buttons on your xbox controller.

Then do "find out what access this address". Then inject your code at those places. I think you do not need Lua script for this at all.

Thank you again mgr.inz.Player.
Could you tell me why the script is not working, just trying to understand it a little better.
i cant simply have a key or controller button repeat by holding down the button, without finding some memory that changes the value associated ?

GAMEPAD_X, the one you used inside keyDown, is nil. You can check it with "return GAMEPAD_X" executed inside "Lua Engine" window.

There is only GAMEPAD_X entry inside state table (result of getXBox360ControllerState function is a table)

Anyway, It will not work. If you can not use left mouse button and controller X button at the same time, methods with keyDown, keyUp, doKeyPress, mouse_event will just not work.

You have to find how the game gets controller states, be it XInput or DirectInput. Then inject code there.

OK thank you mgr.inz.Player.
When i started looking into this rapid fire button, i thought it was going to be something simple to do, was i wrong.
Thank you for taking the time mgr.inz.Player it is very appreciated.

It's tricky do to it when you want to play with controller. It is much easier when you only use mouse+keyboard.

Anyway, lets find out what it is using. Probably both: dinput8.dll and XInput1_4.dll

What result you get when you execute this Lua script inside "Lua Engine" window, of course after opening game process:

Hello mgr.inz.Player.
The result of that script is -
game uses xinput: C:\Windows\SYSTEM32\XINPUT1_3.dll

I think you can hook XInputGetState function. And do the magic there.

Hello mgr.inz.Player, struggling on this, have gone to enumerate dll's and symbols, and found XInputGetState function, and added a script to my cheat table, but not exactly sure what to put in the table, currently trying a few variations.

mgr.inz.Player · Posted: Sat Nov 23, 2019 5:30 pm Post subject:

you have to alter XINPUT_STATE structure the one passed to the XInputGetState function.

https://docs.microsoft.com/pl-pl/windows/win32/api/xinput/nf-xinput-xinputgetstate

https://docs.microsoft.com/pl-pl/windows/win32/api/xinput/ns-xinput-xinput_state

Maybe I will find some free time to make "simple" AA script for XInputGetState from XINPUT1_3.dll

Hello mgr.inz.Player, that will be to difficult for me, but thank you for taking the time to help and explain things.
On a positive note, by unbinding the X button, and then using your above script, it works perfectly.
Its a bit of a work around and the button requires a script enabled to function, but it works none the less.
Thanks for your help mgr.inz.Player i wouldn't have got it working without you.
