What?

It's a GUI framework for Unity that aims to keep things as simple as possible while keeping draw calls to an absolute minimum. I am developing this in tandem with my Deus Ex-based game project The Vongott Chronicles

Why?

GI frameworks for Unity are overpriced, and the built-in API is a ridiculous resource hog with every widget requiring one or more draw calls each. And we can't expect Unity to provide a decent UI system "sometime in the future", when we are ready to develop games now :) So this framework is using the OpenGL API to render widgets, and trying its best to be simple and easy to use at the same time.

FAQ

Does OpenGUI work with C# even though it is written in UnityScript?

Yep, as long as the provided directory configuration is maintained and .cs files are in a subfolder, .e.g /Assets/Scripts. This is because of the Unity compilation order.

I have created widgets, but nothing is displaying. What might be wrong?

Make sure your OGPage object is the current one, and make sure your OGRoot object has a Camera component

Where are the tutorials and documentation?

What about examples?

This repository serves as one. Just download/clone the whole thing.

How can I align objects relatively to the screen?

The "anchor" and "pivot" properties of the OGWidget and subclasses take care of that.

How do I deal with different aspect ratios?

Make sure to use "anchor" and "stretch" to position your content, if you want it to be flexible.
