Activate/deactive DualTouchControls at runtime breaks functionality?

I have Unity's DualTouchControls in my scene to control a car and it works.
But the controls shouldn't be visible right from the start, so I deactivate/active them by script.
This however breaks its functionality. Also in the editor it is not possible to deactivate these controls so I guess that is something one should not do.

I get "There is already a virtual axis named Horizontal registered." which explains the problem, but don't know how to solve it.

I could of course do quirky stuff: move the touchcontrols out of the screen when I don't need it but that doesn't seem right.

EDIT: ok fixed:


In TouchPad.cs, replace CreateVirtualAxis() with this:

Code (CSharp):

1. void CreateVirtualAxes()
2.         {
3.             // set axes to use
4.             m_UseX = (axesToUse == AxisOption.Both || axesToUse == AxisOption.OnlyHorizontal);
5.             m_UseY = (axesToUse == AxisOption.Both || axesToUse == AxisOption.OnlyVertical);
6.  
7.             // create new axes based on axes to use
8.             if (m_UseX)
9.             {
10.                 if (CrossPlatformInputManager.AxisExists(horizontalAxisName))
11.                 {
12.                     CrossPlatformInputManager.UnRegisterVirtualAxis(horizontalAxisName);
13.                 }
14.                 m_HorizontalVirtualAxis = new CrossPlatformInputManager.VirtualAxis(horizontalAxisName);
15.                 CrossPlatformInputManager.RegisterVirtualAxis(m_HorizontalVirtualAxis);
16.             }
17.             if (m_UseY)
18.             {
19.                 if (CrossPlatformInputManager.AxisExists(verticalAxisName))
20.                 {
21.                     CrossPlatformInputManager.UnRegisterVirtualAxis(verticalAxisName);
22.                 }
23.                 m_VerticalVirtualAxis = new CrossPlatformInputManager.VirtualAxis(verticalAxisName);
24.                 CrossPlatformInputManager.RegisterVirtualAxis(m_VerticalVirtualAxis);
25.             }
26.         }

it is

Code (CSharp):

1. if (CrossPlatformInputManager.AxisExists(horizontalAxisName))
2.                 {
3.                     CrossPlatformInputManager.UnRegisterVirtualAxis(horizontalAxisName);
4.                 }

that is missing in Unity's own implementation.
