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:
> **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 `UnityEngine.UI.InputField.onValueChange' is obsolete.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.

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.
