How to determine if target has Touch/Mouse/Controller/Keyboard

[DiffrenzyKeymaster]

How do I query the input capabilities of my target?

I’m making an app that will run on iOS, Android, Android TV (controller input ) and Desktop.

Currently, you’ll need to use #If __TARGET__=”ios” etc. __TARGET__ is one of: “window”, “macos”, “linux”, “emscripten”, “android” or “ios”

There’s also __DESKTOP_TARGET__, __MOBILE_TARGET__  and __WEB_TARGET__ booleans, eg:

#If __DESKTOP_TARGET__  ‘windows, macos or linux

#Elseif __MOBILE_TARGET__   ‘android or ios

#Elseif __WEB_TARGET__   ’emscripten or wasm

#Else

#Print “IMPOSSIBLE!”

#Endif

This doesn’t allow for everything yet, eg: you can’t tell if a __WEB_TARGET__ has touch input (although you could set a flag if you detect any tough events) or if keyboard/mouse etc are unplugged.

Thanks,that will get me most of the way, but:

I’d like to be able to tell the Android TV from the Android phone, and Chromebook, NumberOfJoysticks() will get me some of the way, but I guess there could be a phone with a Keyboard and Joystick attached, where you still want to use the touchscreen input.

I’d like it to run on Chromebooks, with their upcomming ability to run Android apps, so some sort of function to determine “current platform” query is needed.
