Course interaction issues
I have a problem creating an interaction within a course I'm creating. I need to create a sequence where a button is pressed down and held while some doors open, but if the button is let go before the doors are fully open they stop. Unfortunately the customer also wants this course on the iPad so Flash is out of the equation.
I am having real trouble visualising a concept on how to complete this interaction so any ideas and help will be gratefully received.
Thanks in advance
