RimGui2

WebGL Demo | WebGL Demo2 | Documentation | Unity Discussions

RimGui is an easy-to-use, code-driven Immediate Mode GUI library built from scratch for rapid iteration, rather than extending existing UI Toolkit or uGUI.

I’ve often found existing GUI libraries frustrating to use:

- Building UIs usually involves tedious drag-and-drop operations

- Even simple UI can involve a lot of boilerplate code

- Adding, removing, and managing UI elements like buttons can be a hassle

- Registering and unregistering events like click handlers takes unnecessary effort

With RimGui, there's no need to build UIs with drag-and-drop or manually manage the lifecycle of UI elements.

You can render them with very concise code, like Gui.Button().

Works with all Unity versions 2021+ including 2021, 2022, 2023 & Unity 6.

Render Pipeline Support

- Supports Built-in Render Pipeline, URP, and HDRP.

Customizable

- Easily tweak various parameters to fit your needs.

- You can even render freely from the triangle mesh level for complete control.

Cross-platform Support

- Works not only on PC but also on WebGL and mobile platforms.

Font Support

- Supports custom fonts and texture atlas generation.

Optimized Immediate Mode GUI (ImGui)

- Designed with minimized GC (Garbage Collection) allocation.

- Draw calls are reduced by using a single Shader and Material, and by consolidating all images, including text, into one Texture.

Flexible Scalability:

- You can easily change the size and scale of UI widgets, making it simple to support multiple resolutions. This enables optimal UI display across various screen sizes.
