ModularUI
by brachy
ModularUI is a Forge library for building custom graphical interfaces, offering panels, widgets, layouts and scrolling for mod developers.
What it does
Developers use ModularUI to build screens made of panels that behave like windows and can open and close with animations. The widget set covers buttons, text fields, sliders and other common controls, while layout widgets arrange them into rows, columns, grids and lists. Scrolling uses a custom implementation with smooth animation, and a viewport can transform parts of a screen such as a scrollable list.
Syncing values between the server and the client is simplified, which makes the library usable for things like tile entities and block entities. Text fields accept math expressions and parse numbers. Installation needs UniMixins, and the library is required by 6 other mods, including Personal Worlds, Clayium Unofficial, OK Progressions, Wawel Auth and Vintage Resourcify. ModularUI is released under the GNU Lesser General Public License v3.0 only, and the client needs it while the server may skip it. Files target 1.7.10, 1.12.2 and 1.20.1, with 2.3.92-1.7.10 for 1.7.10 as the latest Forge file.
