In this repository is a collection of extension scripts / effects and controls to enhance your Unity UI experience. These scripts have been gathered from many sources, combined and improved over time.
The majority of the scripts came from the Scripts thread on the Unity UI forum here
You can either download / fork this project to access the scripts, or you can also download these pre-compiled Unity Assets, chock full of goodness for each release:
We have expanded where you can download the UnityPackage asset and widened the options to contribute to the project.
I will still stress however, contribution is optional. The assets / code will always remain FREE

To get started with the project, here's a little guide:
It has been a tough time for all since the last update, but things have been moving steadily along. In the past few months there has been a concerted effort to revamp and update the project ready for Unity 2022, as well as migrating the source repository over to GitHub and refreshing all the things. We hope the new release is better for everyone and we have paid close attention to the editor menus and places to find all the controls for this release.
To get up to speed with the Unity UI Extensions, check out the Getting Started Page.

Much easier that posting a question / issue on YouTube, Twitter or Facebook :D
For customers upgrading from earlier versions of Unity to Unity 2020, please be aware of the Breaking change related to Text Based components. You will need to manually replace any UI using the older Text component and replace them with TextMeshPro versions. This is unavoidable due to Unity deprecating the Text component.
New users to 2022 are unaffected as all the Editor commands have been updated to use the newer TextMeshPro versions.
For more details, see the deprecation notice on GitHub.

More to come
The recommended way to add the Unity UI Extensions project to your solution is to use the Unity package Manager. Simply use the Unity Package Manager to reference the project to install it
New for 2020, we have added OpenUPM support and the package can be installed using the following OpenUPM CLI command:
`openupm add com.unity.uiextensions`
For more details on using OpenUPM CLI, check the docs here.
- Unity Package Manager - manual
Alternatively, you can also add the package manually through the Unity package manager using the scope com.unity.uiextensions, see the Unity Package Manager docs for more information.
- Unity 2018 or lower The pre-compiled Unity assets are the only solution for Unity 2018 or earlier due to the changes in the Unity UI framework in Unity made for 2019. Either clone / download this repository to your machine and then copy the scripts in, or use the pre-packaged .UnityPackage for your version of Unity and import it as a custom package in to your project.
Got a script you want added? Then just fork the GitHub repository and submit a PR. All contributions accepted (including fixes)
Just ensure:
- The header of the script should match the standard used in all scripts.
- The script uses the Unity.UI.Extensions namespace so they do not affect any other developments.
- (optional) Add Component and Editor options where possible. (editor options are in the Editor\UIExtensionsMenuOptions.cs file)
All scripts conform to the BSD3 license and are free to use / distribute. See the LICENSE file for more information =
All these scripts were put together for my latest book Unity3D UI Essentials Check out the page on my blog for more details and learn all about the inner workings of the new Unity UI System.
As this repo was created to support my new Unity UI Title "Unity 3D UI Essentials", in the downloads section you will find two custom assets (SpaceShip-DemoScene-Start.unitypackage and RollABallSample-Start.unitypackage). These are just here as starter scenes for doing UI tasks in the book.
I will add more sample scenes for the UI examples in this repository and detail them above over time.
