Controller: PS3 Dualshock3 SixAxis
OS: Mac, El Capitan 10.11.2
Game: Portal 2 on Steam
Problem: Portal gun continuously fires after pressing any button that is mapped to the trigger.
My mapping: http://imgur.com/UqzcelG -- everything works great, except the continuous shooting. I also modified Portal's controller settings and remapped those keys to different PS3 buttons, all variations I tried had the same result. Gun just keeps firing, never stops.
I commented in another thread with more details, but it doesn't seem to be getting much attention (possibly because it's older). See http://www.chibatacreations.com/forum/viewtopic.php?f=6&t=56.
