Virtual Joystick with Playmaker?

[polygon]

Hi playmakers,

I'd like to create  custom virtual joystick for a mobile app. It should look like this one, except that I want to create only one joystick that controls the movement speed and also the rotation of the player character (which will be moved by a rigid body and not a character controller)

So I'm not sure how to setup such a control behavior in the right way with playmaker. Does anyone have some ideas how this control method could be realized especially in terms of mobile performance?

Thanks in advance and best regards,
Daniel

Get virtual joystick from the asset store, get joystick pack of materials.  VJ has playmaker support.  It's super easy to set up and the writer gives great support.
