Hi. I'm trying to figure out if there's a way to have a script that only triggers off gamepad input from a specific device.
Specifically, this is for a Lenovo Legion Go, connected to an 8bitdo arcade stick, which can toggle between presenting itself to the system as an XBox 360 controller or a Switch Pro Controller.
I'd like to leave the Xbox mode alone to use in games, but map the buttons in Switch mode to keyboard commands for opening specific programs, volume control, opening the settings menu, etc.
I'd like to have it trigger off some consistent aspect of the Switch Pro Controller mode, so that it doesn't matter how many other game controllers are connected, or what order they were connected in -- Switch input gets translated to keyboard commands and other input passes through without being altered.
Is this possible?
Thanks

Re: Per-device joystick mapping
Hi @Thraeg
The problem will probably be that Autohotkey or Windows does not natively recognize input from the 8bitdo Arcade Stick in Switch mode
Because otherwise you wouldn't need a selector to switch between PC (Windows) and Switch (Console).
But alternatively you could do it so that you use the second selector (LS,DP,RS) to change the button layout because LS and D-pad are used in most games for directional input and RS is only used for the camera.
In short:
Selector is set to RS
move the Stick -> the Script detects input from RS -> activates the script
Selector is set to LS
move the Stick -> the Script detects input from LS -> deactivates the script
Here is an example which uses the XInput function to map a sound beep to the a-Button if RS is selected:
or you could use a button combination like holding start & select for 2s to start / stop the script.
