Is there a way to disable the on screen analogue sticks when running a game on a mobile device? If so, how?
Theres should be option for that in Edit-> Project Settings i dont remember which section exacly (im on tablet and cat check it right now ; p)
To add to 's answer. This option is located under Project Settings > Engine > Input > Mobile. Then change the Default Touch Interface to clear or another interface if you set that up.
If you need to get the Virtual Joysticks back. Click the drop down arrow and choose View Options and enable Show Engine Content and they will become available to pick again.
I hope that helps.
