Ultra App Kit: Let's Solve the Desktop UI Problem



The foundation of our new game development tools is here, with a close-to-the-metal framework for building desktop applications.

Close-to-the-Metal Framework for Desktop Applications

We're approaching the end of a loooooooooong cycle of research and development...several years, in fact, have been spent building the fastest game engine in the world. A great game engine needs a great user interface, and Ultra App Kit provides exactly what we need. This will provide the backbone of our new game editor, as well as a mechanism for user-created extensions. You can get your hands on this technology and start building your own desktop applications by backing our new crowdfunding campaign on Kickstarter. (You have the option to purchase through IndieGoGo or directly through our website at a later date.)

We made it, with time to spare! That means this software is going to become a reality by Christmas.

Three stretch goals remain:

  • Linux and Mac support
  • C# and Lua support
  • Visual interface designer

Based on your comments, the Mac / Linux goal is the most popular, but a survey will be taken at the end of the campaign to verify this.

Next Steps

The sky is the limit, but we need to get this out to the right audience. I'm counting on your to spread the word across the internet and reach interested parties. Fortunately, a successful Kickstarter campaign carries some validity. When a crowdfunding campaign first launches, it is spam. Once it is successful, it is a news story. So I think you will find the audience is more receptive when you post about the successful campaign now.

Man I would really like to see Mac and Linux support. So few options for true cross platform that isn't super expensive and doesn't suck.

This is looking great. I've always been bothered by the available options for a lightweight GUI. I also think that cross platform support for a GUI framework is quite a big deal and can only second the opinion that this is the most important bonus goal.

From the material you have posted, there is one thing I am quite curious about: In your code example you are placing the button and panel using fixed coordinates and sizes. Moreover, the widget is only created once and does not run through a loop, where the user would constantly recalculate the coordinates. When looking at the video, however, the widgets resize, when you resize the window. Did you implement a resizing-handler for the GUI shown in the video or are you planning to have a sort of automatic layouting system (i.e. defining anchors and having horizontal/vertical/grid layouts, which automatically manage the sizes of their contents) (clearly such a layouting system internally needs to use such a resize-event-handler but the question is, whether the logic behind that is tucked away some place within the API or whether a user needs to implement the handler themself). Maybe you could extend the example code by the GUI which is shown in the video and if there is such a system leave some words about how you plan it to work.

There is a Widget::SetAlignment method that can be used to lock an edge to its distance from the parent edge, like in BlitzMax.
