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 plague virus

[]([https://discord.gg/wJxqmfRqaN](https://discord.gg/NeQWTETTbj))
[](https://ko-fi.com/kiwikcz)
# 📖 Description
**Dificulty**

In easy an infected zombie will appear every 100 zombies
in normal 1 in every 50
on hard 1 every 10 zombies

**mechanics**
The zombie with the ability to infect you when it hits you will give you the zombie infection that appears in the effect bar. You have 7 days in Minecraft to obtain the cure before turning into a full zombie. The recipe for the cure is in the new Great Library of the Plains Villagers, or in books you can find in the Dungeons.

**Effects**

On the first day, you won’t show any symptoms.
On the second day, you’ll have a fever and be hungry.
On the third day, you’ll get sunburned and it will take longer to break blocks.
On the fourth day, you won’t be able to break blocks anymore.

**Complete Zombification**
Complete Zombification if you didn’t obtain the cure before becoming a zombie. You’ll lose control of your body and can only observe your zombie self. You can only cure yourself with the recipe you formulated beforehand. If your zombie dies, you can’t respawn.


Zombie Horse Spawn

Zombie horde

# Zombie horde

Zombie horde turns vanilla zombies into a scalable siege system for Fabric.

Zombies do not just run at the player anymore. Depending on settings and progression, they can break blocks, place blocks, build pressure paths, and coordinate different combat roles to keep survival challenging over long play sessions.

## Core Gameplay Features

– **Block Breaking AI**
Zombies can destroy valid obstacles to open a path toward players.

– **Block Placing AI (Hardmode)**
Builder zombies can place blocks for vertical pressure and assault routing.

– **Bridging Behavior**
When no direct route exists, zombies can place blocks to continue advancing instead of failing path attempts.

– **Special Zombie Variants**
Multiple variants with different combat profiles, including heavy, fast, and tool-focused attackers.

– **Role-Based Pressure**
Some zombies focus on breaching and breaking, while others focus on building and route creation.

**Short Legacy Video from the Zombie horde mod (1.1.1):**
Current version includes major AI, bridging, block placing/breaking, variants, and scaling improvements.

## Progression and Scaling

– **Difficulty Slider (-100 to +100)**
Live control over overall horde strength.

– **Daily Growth Speed (-100 to +100)**
Control how quickly zombie waves and power scale over time.
Set to `-100` to disable daily growth.

– **Day-Based Progression**
Wave size, zombie power, and gear quality scale with progression day.

## World and Server Features

– **Dimension Support**
Optional horde spawning in Nether and End.

– **In-Game Settings UI**
Category-based configuration (`General`, `Horde`, `World`).

– **Full Command Support (OP)**
Runtime control for balancing, events, and server tuning.

– `/zombiehorde strength <-100..100>`
– `/zombiehorde hardmode `
– `/zombiehorde otherdimensions `
– `/zombiehorde dayscaling enabled `
– `/zombiehorde dayscaling speed <-100..100>`
