i actually just mapped this out as well…
y = face button 2, x = facebutton 1
b = face button 2, a = facebutton 1
you can call the event ‘AnyKey’ from your character, and use the node ‘get key name’ to print the name of anything pressed.
now a major annoyance is building a platform specific switch that uses axis values from Touch, and Action values from Vive since the Vive trackpad has very different ergonomic implications for axis values.
hopefully this helps.
