I simulated a 10 second timer that counts down from 10 to 0. This is very simple to do. All you need to do is change the text property of the text value with a custom value and include a delay of 1 second. Then add a callback for the next number with a delay of 1 second. Repeat this until you get to the number 0. There is no need to use variables to simulate a timer.

Here's a demo showing a basic color picker using a container with 4 states for both the colored star and the color swatches.

This is the companion prototype to a 2-part tutorial where we explore the utilization of variables to help us to recreate Apple’s native iOS Weather app. In both tutorials, we go over the different ways Proto.io makes variables available to use in building your prototypes - from the simple example of setting a value in the variables manager and utilizing that value in the prototype to creating and setting a custom variable based on the property of a container and then to the more advanced usage of ternary operators to affect an outcome based on conditions surrounding that custom variable. http://docs.proto.io/videos/ios-weather-app-variables-tutorial-part-1/ http://docs.proto.io/videos/ios-weather-app-variables-tutorial-part-2/

Tumblr has a very nice series of animations that happens when you enter the compose mode. I thought it would be interesting to recreate this in Proto.io to show others how to achieve these kind of effect in their own protototypes. I have made a companion tutorial video where you can see exactly how I did it. This video is available here: http://docs.proto.io/videos/recreating-tumblr-compose-animations-in-proto-io/

Apply color adjustments and filters to your prototypes to create beautiful interactions and animations. https://proto.io/en/new-features/adjustments-filters/

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.
