EasyGui

Developers who write screens for NeoForge can build them on EasyGui's hierarchical rendering structure. Each element sits inside a parent-child hierarchy, so a child's position and size are computed against its parent, and every element includes a transform that applies scale and rotation to the elements beneath it. Scaling of specific UI frames can be turned off when vanilla Minecraft scaling is not wanted.

The library also includes an overlay manager, which lets a mod replace vanilla overlays with its own, and a set of prebuilt elements that can be used as they are, extended or studied as examples. Texture wrappers make texture handling simpler, and an event system provides both targeted events and global events.

EasyGui is published for NeoForge only, for Minecraft 1.21.1, and runs on the client alone since it provides no server-side behavior. The code is not open source and is released under All rights reserved, though the source is publicly available. Required by Formation Arrays, the library is a dependency for at least one other catalog mod. Usage instructions are kept on its GitHub page.
