Help build an independent joystick.

I know how to assemble a virtual joystick in different ways when he controls a character. But I ran into a problem when I needed to create 2 joysticks.

The first is responsible for the movement of the tank, and three times the rotation of the tower.

I can not figure out how to collect them. And that one joystick should work anywhere on the screen from the left side and the second anywhere on the screen on the right side.

It turns out that they either get confused, or both work, or the turn does not work.

Someone did a similar joystick?

Actually, this version is better:
