Spis Ui Api

by spidrone

Spis Ui Api is a NeoForge library for building UI elements, including custom fonts, animated textures and text drawing with wrapping.

NeoForgeClient and serverAll rights reserved1.21.1

What it does

Developers use the library to draw text with bounding boxes, automatic line wrapping and line splitting through a custom drawString method. Custom fonts can be registered from TTF files placed in an assets folder, then declared as resource locations for use in UI screens. Other UI elements such as animated textures are included, so mod authors need not write these from scratch. Files target NeoForge for 1.21.1 and the mod runs on client and server, so both sides need it. It is published under All rights reserved and is not open source.

  2. Custom font registration
