JexUI – Immediate-Mode Game UI

JexUI is an immediate-mode game UI framework for Unity, designed to help developers create interactive runtime interfaces directly from C# code.

Build menus, HUDs, inventory systems, settings panels, and other game interfaces without relying on Unity Canvas components. JexUI supports both screen-space and world-space UI, along with customizable skins and styles.

Key Features

• Immediate-Mode API – Define and control your UI directly from C#.
• Screen-Space & World-Space UI – Create traditional screen interfaces or interactive UI elements in your 3D world.
• Common Controls – Buttons, toggles, radio buttons, sliders, progress bars, text fields, and multiline text areas.
• Advanced Views – List views, grid views, tree views, tabs, foldouts, and scroll views.
• Popups & Overlays – Context menus, tooltips, notifications, popup panels, and modal dialogs.
• Interactive Panels – Movable and resizable panels, drag-and-drop, and other interactive behaviors.
• Layout & Drawing – Layout controls, custom drawing, clipping, text alignment, and measurement.
• Customizable Appearance – Skins, styles, sprites, and 9-sliced backgrounds.
