NGUI 3 Support / Re: NGUI Virtual Joystick

Hi Guys,
i'm trying to use this script i fund on this post, but i get an error while unity compile it
Error:
Assets/NGUI/Scripts/Interaction/UIJoyStick.cs(14,27): error CS0246: The type or namespace name `IgnoreTimeScale' could not be found. Are you missing a using directive or an assembly reference?
by the way, next month i was using a script like this one with NGUI and i don't remember where i fund it, but i'm pretty sure i didn't copy past any line of code to fund it....
isn't it another existing script in NGUI package ??

by the way, next month i was using a script like this one with NGUI and i don't remember where i fund it, but i'm pretty sure i didn't copy past any line of code to fund it....
isn't it another existing script in NGUI package ??
