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](http://bit.ly/UnityUIScriptsForumPost)
You can either download / fork this project to access the scripts, or you can also download these precompiled Unity Assets, chock full of goodness for each release:

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.
All scripts conform to the BSD license and are free to use / distribute. See the [LICENSE](https://bitbucket.org/ddreaper/unity-ui-extensions/src/6d03f25b0150994afa97c6a55854d6ae696cad13/LICENSE?at=default) file for more information
As this repo was created to support my new Unity UI Title ["Unity 3D UI Essentials"](http://bit.ly/Unity3DUIEssentials), 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.
