Zombie Improvements

# Zombie Improvements

This mod improves zombie leader and reinforcement mechanics and fixes a few bugs with them.

## What?

If you didn’t even know these were a thing, here’s a rundown from the Minecraft wiki:

> On all difficulty levels, damaged zombie mobs (including husks, drowned and even zombified piglins) call all other zombies within a 67×21×67 to 111×21×111 area centered on the attacked zombie to target the attacker.
>
> In Hard difficulty, zombies can spawn additional zombies to “help” when damaged. Each zombie has a “likeliness to call reinforcements” statistic ranging from 0–10%, and “leader” zombies (0–5% depending on regional difficulty) get a bonus of 50–75 percentage points to the stat.
>
> On Hard difficulty, zombies have a 5% chance to spawn as leaders. Leader zombies can spawn other zombies as reinforcements.

## So what does this mod do?

There are a few issues with these mechanics:
– You can’t tell if the zombie you’re attacking is a leader or not.
– There is no visual/audio cue when zombies spawn additional reinforcements.
– There are a few bugs which make these mechanics less relevant.

This mod alleviates all of these issues by:
– Adding a red aura effect around leader zombies, identical to the charged creeper effect, but red color.
– Adding unique textures and sounds for leader zombies.
– Increasing the size of zombies that are leaders.
– Adding a sound that plays when a zombie spawns in additional reinforcements. The sound that will be played is the block breaking sound of the block the freshly spawned zombie is standing on, played 5 times in a span of 2 seconds.
– Appending a “Leader” prefix to the name of the leader mob.
– Fixing two vanilla bugs, namely [MC-219981](https://bugs.mojang.com/browse/MC/issues/MC-219981) and (1.21.1 only) [MC-14800](https://bugs.mojang.com/browse/MC/issues/MC-14800).

There’s also a few additional tweaks:
– Configure the attack damage of leader zombies. By default, it’s slightly increased compared to normal zombies.
– Configure the spawn chance for leader zombies.
– Allow only leader zombies to spawn additional reinforcements.
– Prevent mob spawners from spawning leaders.
– Prevent zombies spawned by mob spawners from spawning additional reinforcements.

Zombie Villager Variants

A mod adding the Drowned Villager and Villager Husk. These Zombie Villager variant mobs correspond to the Drowned and Husk zombie variants including a copy of all conversion behaviors.
– A drowning villager husk will become a zombie villager.
– A drowning zombie villager will become a drowned villager.
– Drowned and Husks can convert villagers directly into their zombie villager variants.
– Both can be cured into regular villagers the same way as zombie villagers.

Both the drowned villager and villager husk can also spawn naturally with similar odds to the vanilla zombie villager.

Additional optional zombie villager variants can spawn or convert while a compatible mod is present. These variants will not appear naturally otherwise but can be spawned with spawn eggs available in the creative menu or by commands

Zombie Variants


Tired of seeing the same old zombie over and over again? Since the early days of Minecraft, the zombie’s appearance hasn’t changed much — and while that’s fine, why not add a little more variety?

This mod introduces 15 new zombie variants, each designed to spawn in specific biomes, bringing more life (or un-life) to your world! Don’t worry — the classic zombie will still appear in most common biomes like plains. But now, depending on where you are, you’ll encounter new types of zombies that match their surroundings.

For example:

– In snowy or frozen areas, you’ll meet the Frozen Zombie.

Below, you’ll find a detailed list of each zombie variant and the biome it spawns in.

Zombie UUID Preservation

> ⚠ The 1.21 branch of this mod is technically compatible with 1.20, but notheless requires at least **Java 21** to function.

# Zombie UUID Preservation

If you use texture-packs that randomize villager textures, you may have noticed that their appearances change after being zombified or cured.
This mod fixes that, by ensuring the villager’s UUID is preserved after each conversion.

**The fix occurs on the server-side**

Although being developped around villagers, this also takes effect on some other forms of conversion:
– Piglin and Hoglin zombification
– Skeletons turning into strays
– Husks turning into zombies
– Zombies turning into drowned
