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.

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

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 an expand/collapse menu example that can be created using container states.

Using color adjustment and filters, I've simulated the iOS spotlight animation. Learn how you can apply these filters at https://proto.io/en/new-features/adjustments-filters/

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

3 prototypes showing different uses of the form components for iOS 1) Activate / de-activate button when checking / un-checking Terms of Service 2) Capture text input to change property 3) Change number of tickets - limit 8 See how they were created step-by-step in the Using Forms webinar video: https://vimeo.com/118919393 This version on Vimeo includes time-codes so you can jump to particular sub-sections (repeated below as a preview): > Range of iOS form input controls 2:02 > Labels 2:17 > Text fields 2:32 > Setting placeholder text 3:04 > 5 Input Types that display the appropriate iOS keyboard (Text, Numeric, Email, Password, Telephone) 3:30 > Using the Telephone keyboard for credit card number input (large # keys) 4:08 > Need to view prototype on device in order to see the range of keyboards 5:59 > Multi-line text area input field 6:24 > Search Bar 6:40 > Checkbox control customization 7:22 > On/Off Switch control customization 7:52 > Slider control customization 9:27 > Increasing size of slider handle 9:47 > Picker Wheel Customization 10:00 > Prototype example: Activate button when checking terms of service 10:42 > Create a button with two states (using convert to container) 12:55 > Adding interactions to a checkbox control (on change activation/deactivation) 14:45 > Definition of variable and range of uses 17:04 > Using variables with text field interactions 18:25 > Prototype Example: Using a variable to capture text input and show it in a different text box using change property. 23:27 > Prototype: Use variables to increment and decrement counter showing number of tickets being purchased. 28:40 > Searching full range of icons built into Proto.io 29:10 > Using a variable to limit the range of tickets (0 to 8) 32:46 > Copying and pasting interactions with Variables 40:08

This is an example of a Navigation Bar that disappears on any downward scroll and re-appears on on any upward scroll.
