About this Mod

Welcome to BorisLib!

This is a Library for most of my heavier Server-Sided Fabric Mods

This library has a few key features:

  • Polymer-based Graphical Items for server-sided GUIs
  • A robust framework for generating paged and configurable server-sided GUIs
  • A built-in powerful mod config / properties file manager
  • A system for storing mod data on Players, Worlds or Globally, with easy offline access
  • A 'Conditions' system that acts like potion effects with the granularity and stackability of entity attributes
  • A game-event system for keeping track of specific player actions
  • A timer and login callback system for events that take place after a certain amount of time, or when a player returns to the server.
  • A server-based velocity tracker for estimating the player's movement vectors without specialized packets
  • A library of modular, pre-made, geometric and animated particle effects
  • A whole bunch of useful utility methods for various mathematical operations, data structures, algorithms, text and sounds.

Texture Pack

The server has the ability to automatically generate and serve the mod's texture pack to your players when they connect. To do this, you must enable auto-host. This is super easy to do in a few steps:

  1. Launch the server with the mod installed at least once to generate the configs
  2. Go into the 'config' folder of the server, there should be a folder called 'polymer', and inside that there should be a file called 'auto-host.json'
  3. In 'auto-host.json', in the first few lines there will be a line that says "enabled": false, change this to true.
  4. (Optional) You can also set the value to make the resource pack required by players, or set the "message" line to inform players why the resource pack is important to download when they are prompted to have it be auto downloaded.

If everything is done correctly, then players will automatically load into the server with the resource pack installed.
