Introduction

UI Toolkit Animation

UI Toolkit Animation is a powerful and performant animation library designed to streamline the animation process for Unity UI Toolkit. This asset empowers you to create dynamic and engaging user interfaces with minimal coding effort, through C# scripting. No need to add any script in the inspector all you have to do is call through C# 😊. The Library works for native UI Elements and it also works for custom UI Elements so there’s no limitation to what you can use it for.

Feel free to contact me over at this email kostomapp@gmail.com if you have any issues, requests or question. I’m also open to suggestions on how to improve the asset so feel free to give me some suggestions on what to add and what you think would make your workflow easier.

Please 🥹 make sure to drop a review on the Asset Store page if you like the asset. It helps a lot:

Setup

Firstly, build the UI Element through either the UI Builder, UXML or through C#. Then create a script you want to control the animation through and import the namespace.

using Kostom.Animation;

Components

Color

This method (element.AEColor()) animates element's text color over a certain duration. Check out the code example below.

Background Color

This method (element.AEBackgroundColor()) animates element's background color over a certain duration. Check out the code example below.

Scale

This method (element.AEScale()) animates element's scale over a certain duration. Check out the code example below.

Scale X

This method (element.AEScaleX()) animates element's scale on the x-axis over a certain duration. Check out the code example below.

Scale Y

This method (element.AEScaleY()) animates element's scale on the y-axis over a certain duration. Check out the code example below.

Move

This method (element.AEMove()) animates element's transform which in turn move the element over a certain duration. Check out the code example below.

Move X

This method (element.AEMoveX()) animates element's transform on the x-axis which in turn move the element on the x-axis over a certain duration. Check out the code example below.

Move Y

This method (element.AEMoveY()) animates element's transform on the y-axis which in turn move the element on the y-axis over a certain duration. Check out the code example below.

Opacity

This method (element.AEOpacity()) animates element's opacity/fade over a certain duration. Check out the code example below.

Rotate

This method (element.AERotate()) animates element's rotation over a certain duration. Check out the code example below.

Border Radius

This method (element.AEBorderRadius()) animates element's border radius over a certain duration. Check out the code example below.

Border Width

This method (element.AEBorderWidth()) animates element's border width over a certain duration. Check out the code example below.

Border Color

This method (element.AEBorderColor()) animates element's border color over a certain duration. Check out the code example below.

Letter Spacing

This method (element.AELetterSpacing()) animates element's letter space / text spacing over a certain duration. Check out the code example below.

Text Highlight

This method (element.AETextHighlight()) animates element's a part of the text wrapped in between <hl></hl> over a certain duration. This code works on Label and Button elements only. Check out the code example below.

Text

This method (element.AEText()) animates between texts over a certain duration and it contains different text animation effects. This code works on Label, Button and TextField elements only. Check out the code example below.

Custom

This is a powerful method (element.AECustom()) that can be used to animate/modify any element or any custom element's value that uses color, int or float over a certain duration. Check out the code example below.

Special Components

On Hover

This method (element.AEOnHover()) animates element on hover and undo the animation when it's not been hovered on and you can also animate other elements and they would also be undone when the initial element is not been hovered on anymore. e.g This code animates three UI elements in Unity. When element1 is hovered over, it changes its background color to black. Simultaneously, element2 scales up, and element3 changes its background color to white and increases its border width, all over a duration of 0.5 seconds.

On Click

This method (element.AEOnClick()) animates element on click and undo the animation when it's not been clicked on and you can also animate other elements and they would also be undone when the initial element is clicked again. e.g This code animates three UI elements in Unity. When element1 is clicked over, it changes its background color to black. Simultaneously, element2 scales up, and element3 changes its background color to white and increases its border width, all over a duration of 0.5 seconds.
