Ultimate Saver

Per-weapon ultimate charge storage for Hytale. Each weapon remembers its SignatureEnergy (ultimate) independently.

Description

UltimateSaver

Per-weapon ultimate charge storage for Hytale. Each weapon remembers its SignatureEnergy (ultimate) independently.

⚠️ IMPORTANT: This is NOT a regular mod! This is an Early Plugin (Hyxin/Mixin mod). It will NOT work if placed in the Mods folder. The CurseForge app does not install it correctly — you must install it manually. See the Installation section below.

The Problem

In vanilla Hytale, ultimate charge is lost when you switch away from a weapon. If you charged your ultimate to 80% and switch to another weapon, that charge vanishes. This mod fixes that.

Features

  • Ultimate charge persists on weapon switch — the main feature! No more losing your charged ultimate when switching weapons
  • Individual charge tracking — each weapon stores its own SignatureEnergy in item metadata
  • Partial charge support — saves any charge level, not just full ultimate
  • Persistent storage — charge is saved when you:
    • Switch to another weapon
    • Store it in a chest
    • Trade with other players
  • Multiplayer compatible — works correctly when other players pick up your weapons

Technical Details

This mod uses an event-based architecture with Mixin injection rather than tick-based systems. This means:

  • Zero performance overhead during normal gameplay
  • Code only executes when weapon stats are recalculated (on weapon switch)
  • No continuous polling or per-tick checks

Requirements

Installation

⚠️ The CurseForge app only installs mods into the Mods folder. This mod is an Early Plugin and must be installed manually into the earlyplugins folder.

Single Player / Client-Hosted Server

  1. Download Hyxin.jar and place it in:
   UserData/EarlyPlugins/
  1. Download UltimateSaver-*.*.*.jar and place it in your world save folder:
   UserData/Saves/<YourWorldName>/earlyplugins/

(Create the earlyplugins folder if it doesn't exist)

  1. Launch the game and load the world

Linux users: The folder must be named exactly earlyplugins (lowercase). Linux is case-sensitive, so EarlyPlugins won't work.

Dedicated Server

  1. Download Hyxin.jar and place it in:
   <ServerRoot>/earlyplugins/
  1. Download UltimateSaver-*.*.*.jar and place it in the same folder:
   <ServerRoot>/earlyplugins/
  1. Add --accept-early-plugins to your server launch command. Example:
   java -Xms4G -Xmx4G -jar Server/HytaleServer.jar --assets ../Assets.zip --accept-early-plugins
  1. Start the server. You should see it loading mods from the earlyplugins folder in the console.

Linux users: The folder must be named exactly earlyplugins (lowercase). Linux is case-sensitive.

How It Works

When you switch away from a weapon, the current SignatureEnergy (ultimate charge) is saved to the weapon's item metadata. When you switch back, the charge is restored from metadata.

This allows you to have multiple weapons with different charge levels — perfect for combat loadouts where you want pre-charged ultimates ready to use.

Compatibility

  • Works with any weapon that uses the standard SignatureEnergy stat system
  • Compatible with other mods that don't modify weapon ultimate behavior
