This one-screen prototype demonstrates some of Proto.io animation functionality.

Pitch

If you need to get the Y position of a vertically scrolling container, create a text box. Then on the container scroll trigger, set a variable that evaluates the numerical callback value from the event (Y position). Then add a callback that changes the text property of the text box by reading from the variable.

Hey guys! I'm back with an amazing prototype for you guys. This has been my longest and quite a challenging redesign project for IMDb whose prototype is pretty awesome and contains lots of stuff like Nested Containers, a bit of animation, some really beautiful visual elements and interactivity for you to explore! I had so much fun making it with Proto.io and I truly hope you guys love it and would love to know your views and suggestions on how can I improve it :) Cheers! Aman
