Wondering how to get these kind of controls that are used in play.google.com/store/apps/details
I've seen games that hover a d-pad on one side, .. while some of them use tap anywhere to move the player.
This one has something special there, even if I tap behind the tank and say move a circle swipe.. the tank will literally turn a circle.
So its not like tank is moving in the direction of the touch.
Anyone has a idea how this works?
