First, I don’t found documentation for accelerometer configuration.
I have read this : https://docs.unrealengine.com/latest/INT/Programming/Gameplay/Framework/Input/index.html
But no special precisions for mobile settings.
And this is a subject that the mobile section don’t specifically adress : Mobile Game Development | Unreal Engine Documentation
Search on forums and answer hub, but without success. I didn’t see discussions on this subject.
I tried :
Project Settings Input : http://hpics.li/b06a6b2
Player Controller Defaults settings : http://hpics.li/a34fcdc
Player Controller Graph : http://hpics.li/0dc4354
But "Axis Value " output always give “0.0” on my iPad4.
What is the trouble ?
