_BUTTON

[TerryRitchie]

I found a library called:

' GX - A BASIC Game Engine for QB64
' 2021 boxgaming - https://github.com/boxgaming/gx

that had mapped all the _BUTTON vales to keys in a file called gx.bi. I used that as a basis to create the code below if anyone needs the _BUTTON values for the keyboard.

Yes, that was an interesting exercise.   I wanted to have generic and consistent device detection and input mapping across different types of game device inputs (gamepad, keyboard, mouse) using _DEVICEINPUT.  I also found that _DEVICEINPUT didn't work for keyboard button state on macos so GX has a fallback for that OS to use _keydown.

That information was very helpful. Thank you.
