Zach, wizard coder, took some time off to write about the Integrated CEGUI for today’s Dev Blog. We want TUG to be completely moddable and that includes giving modders the ability to create their own UI.
You may have noticed a phrase in the latest patch notes “Integrated CEGUI”. For those that do not know, CEGUI is an open source framework for user interface that we have decided to use so we can present modders with an easy way to make changes to TUG’s UI. In an upcoming patch we will be pushing out the beginnings of moddable UI. One of the reasons we picked CEGUI is because of it’s exposure to Lua, each CEGUI element can be created, modified and destroyed directly through CEGUI’s own Lua interface, which you can access in any TUG script. In addition to CEGUI’s Lua interface, I have also written some short Lua wrapper classes to help with some of the more abstract or mundane tasks. If you’re a programmer, that means you can create your own custom UI elements and tie them to just about anything you have script access to. For those that are more interested in the art side of things, we haven’t forgotten about you. CEGUI comes with it’s own layout editor and we were careful to maintain its functionality during the integration process.
In the above image you can see TUG’s Survival UI layout in CEGUI’s editor. With this tool you can rearrange the UI elements to be anywhere on the canvas, and those changes will be reflected the next time you run TUG. But what if you want to make your own art? CEGUI has that covered too.
CEGUI’s editor also lets you modify imagesets, their name for a texture atlas. Using this tool you can load a .png that you created using your software and section it for easy access to your own UI images.
In both cases, layouts and imagesets, you are free to alter the assets that come with TUG or, if you’re feeling adveturous, create your own. At this time, the UI framework is only partially complete, so while we continue making modifications, there may be some UI elements that are locked from modification, including the Bag, Beltbar, and Equipped item slot. These elements will become available as soon as I can finish writing and testing the new inventory system.
This is just the first step in the UI overhaul, hopefully with much more to follow, including tutorials on best practices and how to get the most out of CEGUI via Lua script.
