Blazingly fast retained layout engine for Bevy ECS.
Blazingly fast retained layout engine for Bevy ECS.
Blazingly fast retained layout engine for Bevy entities, built around vanilla Bevy ECS. It gives you the ability to make your own custom UI using regular ECS like every other part of your app.
Any aspect ratio: Lunex is designed to support ALL window sizes out of the box without deforming. The built in layout types react nicely and intuitively to aspect ratio changes.
Ui flow: Build menus, sidebars and toolbars that react to their content and to the window size with the flexbox-like UiLayout::flow() layout model (inspired by clay) - content hugging, space filling, relative sizing and text wrapping.
Optimized: Unlike immediate mode GUI systems, Bevy_Lunex is a retained layout engine. This means the layout is calculated and stored, reducing the need for constant recalculations and offering potential performance benefits, especially for static or infrequently updated UIs.
ECS focused: Since it's built with ECS, you can extend or customize the behavior of your UI by simply adding or modifying components. The interactivity is done by regular systems and events.
Worldspace UI: One of the features of Bevy_Lunex is its support for both 2D and 3D UI elements, leveraging Bevy's Transform component. This opens up a wide range of possibilities for developers looking to integrate UI elements seamlessly into both flat and spatial environments. Diegetic UI is no problem.

This is an example of a clickable Button created from scratch using provided components. Thanks to ECS, the syntax is highly modular with strong emphasis on components-per-functionality. As you can see, it is no different from vanilla Bevy ECS.
