where can I find the full SDK of methods and variables ?

For this line of code

var touch : iPhoneTouch = iPhoneInput.GetTouch(i);

I got this error message:

Assets/Scripts/Joystick.js(13,55): BCW0012: WARNING: ‘UnityEngine.iPhoneInput.GetTouch(int)’ is obsolete. GetTouch method is deprecated. Please use Input.GetTouch instead.

So I can see that iPhoneInput.GetTouch is obsolete, but I do not want to use Input.GetTouch… which is not iPhone touch if I understood it.

Anyway… I do not want to guess… where can I find all the methods and variables that are defined by the game engine ?

Maybe you have some documentation?

all the stuff that was in iPhoneInput is now in Input

and yes there is documentation: help menu → script reference when you are in unity3
