RimUI Framework

RimUI Framework

A UI library for RimWorld modders, designed to make building in-game interfaces faster and easier. Features:

• 12-column grid and responsive layouts;
• ready-to-use UI components;
• styling for spacing, backgrounds, gradients, images, borders, rounded corners, and shadows;
• JSON-configurable themes;
• animations and interactive component states.

RimUI Framework does not modify the vanilla UI, does not use Harmony, and has no additional runtime dependencies. The mod does not add any gameplay content on its own. It is a library used by other mods. If none of your active mods depend on it, RimUI Framework will have no effect on the game.

Tools

The tools are available under: Options → Mod Settings → RimUI Framework

• Component Showcase — an interactive gallery of RimUI Framework components, built entirely with the framework itself.
• UI Builder — visually assemble grid-based layouts and export ready-to-use C# code to the clipboard.
• Theme Template — export the complete set of theme slots and settings for customization.

The same tools are also available under: Debug Actions → RimUI Developer mode must be enabled.
