Okay I know this might seem like a really strange question, but I need to know if there is a way in Unity to have the game press a button. I am using glovepie for a controller for vibration and I can map the vibration to a button so that if I press a key it will vibrate. I only want to do this at certain times so I don't want to map two different joystick buttons to two different buttons. Any help would be appreciated. Thanks
I don't think this will work, glovepie emulates a controller (I'm using it with a motion tracker on Unity) but Unity don't have "Force Feedback", what you would need to have a vibration on your joystick.
