Hi all, I'm trying to create a pinch zoom effect and for that I followed the cookbook tutorial on this link http://cookbook.gamesalad.com/question/4e2036d8db04ec4f0b000080
It's working fine but I still need one part that seems to be missing from there and it is how to use the distancetouch attribute (the distance between touch 1 and touch2) to zoom the camera in and out, rules are working fine but I still can't manage to create the zoom effect. If anyone has tried this before or knows the rule that I need to use, and is willing to share the secret... Thanks so much!

    To zoom in you have to manipulate the camera size to something smaller than the scene. Im not sure if that tutorial covers that. So hopefully that helps get you on track. Also you can only access the camera attributes from an unlocked Instance of an actor.

    Thanks tenrdrmer, it is working now and it's awesome. It does not feels the native pinch zoom yet but it's doing it./

    Try using an interpolate behavior instead of a change attribute and set ease in and out
