Nucleus-Editor
by JarCentral
Nucleus-Editor is a lightweight ImGui implementation for Fabric that gives other client mods a render callback to draw immediate-mode interfaces.
What it does
Mods subscribe to a render callback provided by the library and draw their own ImGui windows through the Java bindings of Dear ImGui. The runtime libraries for the major desktop platforms are fetched as non-mod dependencies, so the mod itself stays small. Only the client needs it, and the mod is for game version 1.21.4 on Fabric, released under the ISC License and not open source.
Key features
Lightweight ImGui layer
A compact wrapper around the Java libraries for Dear ImGui, without extra UI systems on top.
Render callback
Other mods subscribe to a render callback that runs each frame, where they place their own ImGui windows.
Native runtime libraries
Natives for the major desktop platforms are added as required runtime dependencies, matching the imgui-java bindings.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
