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.

Here is the set of prototypes from the Pro Tips and Tricks webinar: 1) Propagate Events to Items Below 2) Containers as Symbols 3) Conditional Animation 4) Screen Interaction 5) Sketches into Prototype Here is the video of the webinar: http://docs.proto.io/videos/pro-tips-tricks/ The video is broken down with time-codes on Vimeo here: https://vimeo.com/103316955 (under read more) They are also below.

Animated storyboard using low fidelity assets created in Proto.io, and icons found within the Proto.io library and Noun Project. The "On Screen Show" screen interaction is used to animate the content through a sequence of callbacks. See how this was made step-by-step in this webinar video on Low Fidelity prototyping: http://docs.proto.io/videos/low-fidelity-prototyping-with-proto-io/ TAGS: storyboard low fidelity auto-play

An on-boarding carousel concept, created using Proto.io. It is implemented using state animations. Feel free to import into your Proto.io account.

Here is a prototype of a music player. Click play and add different sort of beats to the audio. Sample audio is from http://tricoolore.com/ Enjoy!

This is an example of a sign in screen that validates a username and a password. Feel free to import this fully editable project into your own account for use in your prototypes. Use the following to successfully sign in and proceed to the next screen User Name: john Password: proto.io

A basic animation created by using the Proto.io HTML Component with HTML and CSS. No additional images were needed to be imported to create this animation. The HTML and CSS used was found at: http://codepen.io/ajerez/pen/EaEEOW
