Hi,
It's actually quite simple, don't over think this.
you need to drag the UI joystick prefab in a canvas, or UI panel, if you don't see it in the Game view, make sure it's placed properly.
then,
- create a new gameobject
- add a new Fsm
- in the start state, add an action GetFsmFloat
- target the joystick prefab instance, and get for example the x value of the fsm "Joystick interface", the GetFsmFloat action should guide you to pick the fsm and the value once you have referenced the UI joystick instance.
- make sure the GetFsmFloat action runs everyframe
that's it, now you have the x values of the joystick interface.
check out the object Panel X to see how it's done.
Bye,
Jean
