Ultimate Saver

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

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
