Death Muffler Fix (1.20.1 — Forge)

A client-side fix for the Death Muffler boss bar hiding feature in <button class="wrap-anywhere text-ui-base font-medium text-primary underline cursor-pointer bg-transparent p-0 text-left" title="https://www.curseforge.com/minecraft/mc-mods/mob-grinding-utils" type="button" data-state="closed" data-slot="context-menu-trigger">Mob Grinding Utils</button> 1.1.0.

The Problem

In MUG 1.1.0, the boss bar hiding logic is fully compiled and functional — but it matches boss names with hardcoded English strings:

java

 

 

bossName.contains("Wither") // or "Dragon"

This works fine in English, but in any other language (Chinese, Japanese, Russian, ...) the boss bar is named by its localized title (e.g. "凋灵", "末影龙"), the match fails, and the boss bar hiding silently does nothing.

The Fix

This mod registers an additional CustomizeGuiOverlayEvent.BossEventProgress listener that matches boss names via Minecraft's localization system instead:

java

 

 

 

String witherName = I18n.get("entity.minecraft.wither"); // localized at runtime

bossName.contains(witherName) → cancel the boss bar render

It reads the same player persistent-data flags MUG uses (MGU_WitherMuffle / MGU_DragonMuffle, set by the Death Muffler upgrades), so the hiding behavior stays perfectly in sync with your in-game muffler settings — in every language.

The listener stacks on top of MUG's original one; the original is left untouched and keeps running (including its extra logic), so there is no conflict. English users see no difference; non-English users get the feature working for the first time.
