What is this repository for?

In this repository is a collection of extension scripts to enhance your Unity UI experience. These scripts have been gathered from many sources and 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:


The asset has been full tested on all current versions of Unity 5 (for versions prior to Unity 5.3, please see the archive)

Upgrade Notes

Although not specifically required, it is recommended to remove the old UI Extensions folder before importing the new asset The HSS picker especially had a lot of file changes in this update.

Note In Unity 5.5 the particle system was overhauled and several methods were marked for removal. However, the UI Particle System script currently still uses them Either ignore these errors or remove the UIParticleSystem script in the "Unity UI Extensions / Scripts / Effects" folder

How do I get set up?

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.

Contribution guidelines

Got a script you want added? Then just fork the bitbucket repository and submit a PR. All contributions accepted (including fixes) Just ensure The header of the script matches 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 BSD license and are free to use / distribute. See the LICENSE file for more information

Like what you see?

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.

The downloads

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.

Previous Releases

Note To retain 5.2 compatibility in the 5.3 package, you will see two warnings related to: `UnityEngine.UI.InputField.onValueChange' is obsolete. This has no effect on the package working in 5.4 plus and is only there to maintain backwards compatibility. We will look to update/remove this in a future release, likely after 5.4.
If you have any concerns, feel free to update your code in your project to add the missing "d". Unity have ensured it still works as they have mapped the API change for now.
