KotlinMCUI-Backend (Port)

by StratCube

KotlinMCUI-Backend (Port) is a Fabric library that gives other mods a backend for KotlinMCUI interfaces, so developers can add screens without building the connection themselves.

What it does

The library adds no visible content of its own. It links the KotlinMCUI frontend, which other mods use to present their features, to the game-side code that carries those features out. It is a port of KotlinMCUI-Backend for newer game versions, with fixes for a few bugs found while porting. It runs on the client alone, so servers need nothing. Fabric Language Kotlin, KotlinMCUI and Mod Menu are required.

What the author says

This mod is a library mod, it doesn't add anything by itself, it lets other mods add things easier. This mod acts as a connection between a mod that uses the frontend KotlinMCUI and another mod that uses the features added by it. I have not made any changes to it other than porting and fixing a few bugs.
