    What is this repository for?

    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:

    Download - 2019.6 (aka 2.5)

    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

    Maintenance release 2019.6 - 2.5 - Bug squash

    Its been a while since the last update and although Unity keeps changing, thankfully the parts underneath do not. THanks to some awesome work by our contributors and the test teams, we made a run on some underlying bugs and issues. If you spot anything else, please log it on the BitBucket site for resolution.

    Be sure to also check out the "Examples" option in the Package Manager window to import the samples to your project.

    Be sure to logon to the new Gitter Chat site for the UI Extensions project, if you have any questions, queries or suggestions

    Much easier that posting a question / issue on YouTube, Twitter or Facebook :D

    New / updated features

    • Updated UI Line connector to use relative position instead of anchored position to verify if the Lines need updating.
    • Allow menu prefabs to not have to have canvas components. This allows you to use any type of prefab as a "menu". Adam Kapos mentions the concept on the Unite talk,
    • Updated segment line drawing for Line Lists. Seems Unity no longer needs UV's to be wrapped manually.
    • Updated the AutoCompleteComboBox to display text as entered (instead of all lowercase)
    • Updated the ComboBox to display text as entered (instead of all lowercase)
    • Updated ComboBox Examples to include programmatic versions
    • Further ComboBox improvements including:
      • Upwards panel
      • Start fixes

    Upgrade Notes

    We recommend using the UPM delivery method. If you are using the Unity asset, there should be no issues updating but if you have a problem, just deleted the old Unity-UI-Extensions folder and import the asset new.

    More to come

    How do I get set up?

    As of Unity 2019, there are now two paths for getting access to the Unity UI Extensions project:

    • Unity 2019 or higher 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 and install it.

    Alternatively, you can also use the pre-compiled Unity packages if you wish, however, UPM offers full versioning support to allow you to switch versions as you wish.

    • 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.

    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 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 =

    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.
