I'm new to unity but i have made a custom character controller and I am trying to use unity 5's standard assets cross platform input to make my game compatible with android and iOS (using joysticks for movement).
The Standard assets first Person character controller works with the joysticks but i don't know how (and cannot find out how) to make the joysticks work with my FPController

good luck
