Overview

NGUI is a powerful UI system and event notification framework for Unity (both Pro and Free) written in C# that closely follows the KISS principle. It features clean code and simple, minimalistic approach to everything. Many behaviour classes are kept under 200 lines of code. For a programmer this means a much easier time when it comes to working with the kit — from extending its functionality to tweaking the existing one. For everyone else this means better performance, less frustration, and more fun.

Features

Workflow

Working with NGUI is just like working with Unity. Drag & drop ready-made controls such as button, checkbox, scroll bar and many others right into the Scene View or make your own using a Lego-like approach — want the button to scale as you hover over it? Attach the UIButtonScale component. Attach the scripts you need and nothing else. Save controls as prefabs and re-use them anywhere. It’s the Unity-like approach to UI creation.

Free Version

NGUI 2.7.0, the last of NGUI 2 cycle is now free and can be downloaded here. It’s dated September 2013, and comes in full source code form and without any kind of DRM. It’s feature-limited and not nearly as streamlined as the current NGUI 3-based releases, and doesn’t come with support — but if you can’t afford NGUI 3 or just want to try it, you’re welcome to grab it.

Just note that in order to use it for professional purposes you must fall under the same conditions as Unity Free: “free version may not be licensed by a commercial entity with annual gross revenues (based on fiscal year) in excess of US$100,000, or by an educational, non-profit or government entity with an annual budget of over US$100,000.”

As a footnote, when publishing NGUI extensions on the Asset Store, it’s best to not include the NGUI code at all. Asset Store overlords are quite used to the “requires NGUI to run” condition. :)

Licenses

Once you download NGUI, you are no longer eligible for any kind of refunds, as it comes in full source code form. Software delivered in source code form cannot be simply “taken back”. It’s not like returning a shower curtain back to WalMart. Please think before you license NGUI, as there is no going back.
