1. Adding an Animation Component

Go to the page you’d like to add the animation to, click the + button, and find the Animation
Component
(under Media category). Click Insert.

 

 

The Animation component loads a default ‘Umajin’ text animation. With the Animations Component selected, head to
Properties > Beauvoir.

Find the dropdown arrow next to Start Animation.

The default animation will have three states of which the animation can start at. (Press PLAY to view the default
animation.)

 


2. How to create an Animation

To create the 2D animation we support Spine (http://esotericsoftware.com/)
which is a fantastic third party tool for creating 2D animations.

After downloading and installing the latest version of Spine from their website, you will need to go into Spine
Settings. In the Application tab, use the drop-down to change the Spine version to 3.7.94.

 

Here are some examples of the UI animation that can be created:

Here is a project with some sample animations you can add to your new templates list with this link Install Template. Alternatively here
are the animations in a zip file that you
can download and add to your own projects.


3. How to export from Spine

  • Click the Export button (CTRL+E for windows or CMD+E for Mac).
  • Have JSON selected.
  • Have ‘Create atlas’ selected.
  • Click on settings next to ‘Create atlas’
  • Check the output is PNG and the packaging is
    Atlas
    .
  • Also adjust the size. It must be a square size e.g. 1024 x 1024 or 2048 x 2048.
  • Click ok and then click Export.
  • Spine will create 3 files, an Atlas, a JSON file and a PNG.

 


4. Apply your Animation to Umajin

  • Copy your exported Spine animation files (.atlas, json and .pngs), open the Resources Folder
    for your Umajin Project, and paste the files into the animation folder.

 

  • In the Properties Inspector, under the Appearance heading,
    Animation file, click the folder icon and select your Animation.
  • Select the Animation in the drop-down for Start animation if you want your Animation
    to play as soon as the page is viewed.

 

  • You can choose to loop the Animation or not.

 

  • You can choose the option to play the Animation on Press animation.
  • Press play and check your Animation is working as you’d expect it to.

There are a special set of actions for controlling animations. These are under the Animation tab in the Action Selector.
