ZombieApocalypse999

New Features

- Added: A fully configurable custom texture pack system that sends the server's zombie pack to players when they join, with optional download prompts and caching so returning players only download it once - Added: Server owners can now enable or disable the custom crafting system entirely (Cure Potion and Purified Zombie Heart recipes) - Added: Zombie Hearts can now be enabled, disabled, and have their drop chance adjusted to fit the server's difficulty - Added: Zombies now randomly spawn as Zombie, Husk, or Drowned variants in any biome, each with its own custom texture - Added: Zombies spawned from dungeon spawners inside ruined structures also use the new random variants - Added: The custom texture pack is optional by default, so players who decline it are not removed from the server

Bug Fixes

- Fixed: Zombie Heart drop chance was not being respected, causing hearts to always drop at a fixed rate regardless of the configured chance

* Fixed a bug where zombies would target spectator and creativemode players

New Features

- Ruined Hospital Structure — A new 2-story white concrete hospital that generates naturally in the world - Features a "HOSPIT L" sign on the front with a missing letter and a red cross symbol - Contains multiple patient rooms across both floors, each with a bed and a loot barrel - Two storage rooms on the first floor with higher-value loot barrels - Redstone dust scattered on floors throughout the building to simulate blood - Vines growing on the exterior walls for an abandoned look - Cobwebs in corners and ceilings - Random structural damage — missing blocks in walls, floors, and ceilings - Two zombie spawners hidden underground beneath the first floor - Staircase connecting the first and second floors - Configurable spawn chance, biome restrictions, and Y-range in structures.yml

Hospital Loot

- Patient Room Barrels — Each contains a random amount of: Rotten Flesh (0-4), Cobwebs (0-5), Redstone (0-3). Each possible amount has an equal chance of being selected, including 0 - Storage Room Barrels — Each contains a random amount of: Iron Ingots (0-8), Diamonds (0-3), Mending Book (0-1), Cobwebs (0-8). Same equal-chance system for all amounts - All loot is scattered randomly across barrel slots rather than stacked in order

New Features

- Crafting Menu GUI — New /zombieapocalypse999 crafting command (aliases: /za crafting, /za999 crafting) opens a crafting menu with two recipe buttons and a close button - Zombie Heart Drop — All managed zombies now have a 5% chance to drop a custom "Zombie Heart" item (rotten flesh with custom NBT, stacks to 64) - Purified Zombie Heart — New craftable item made from 8 Zombie Hearts and 1 Cure Potion in a crafting GUI. Eating it permanently grants +2 extra hearts - Permanent Extra Hearts — Extra hearts from Purified Zombie Hearts persist through infection, mutation, curing, and all gameplay events - Zombie Heart drop chance is configurable in config.yml under custom_drops.zombie_heart

#### New Mutation: The Leech - A new zombie mutation, "The Leech," has been added. - The Leech has a chance to spawn based on the spawn_chance setting in the config.yml file. - Abilities: - Leeching Aura: The Leech has a passive aura that drains health from nearby players and zombies, healing itself in the process. - On-Hit Heal: When The Leech damages a player, it heals for a portion of the damage dealt. - Death Heal: When The Leech dies, it releases a burst of healing energy that heals other nearby zombies. #### Bug Fixes - Fixed a bug where the day cycle and mutation rate would increase even when no players were online.

#### New Mutations - Added Cryo Zombie: A frost-based zombie with abilities focused on slowing and freezing players. - Added Inferno Zombie: A fire-based zombie that creates environmental hazards and attacks from a distance. #### Configuration Rework - Modular Mutations: The config.yml file has been restructured to make all mutations modular. Each mutation type now has its own subsection for easier management. - Customizable Abilities: All abilities for the new Cryo and Inferno zombies (e.g., freeze chance, fireball cooldown) are now fully customizable in the config. - Simplified Disabling: Mutations can now be disabled by setting their spawn_chance to 0. The separate enabled flag has been removed. - Configuration Warning: The server console will now display a warning message on startup for each mutation that has a spawn chance of 0, to alert server owners of intentionally or accidentally disabled mutations. #### Command Updates - The /za spawn command has been updated to allow for manual spawning of cryo and inferno zombies. - The help message for the command now lists the new zombie types. #### Zombie Population Control - Worldwide Zombie Limit: Added a configurable max_worldwide option (default: 100) to limit the total number of special zombies allowed to exist in the world at one time. - Per-Chunk Zombie Limit: Added a configurable max_per_chunk option (default: 20) to prevent too many zombies from spawning in a single chunk. - Dynamic Spawning: The zombie spawning system now respects both the worldwide and per-chunk limits, preventing new spawns if either cap is reached.

Bug Fixes

* Resolved an issue that caused the plugin to fail to load if the config.yml file was missing.

fixed the issue where mostly Frost Zombies spawned and didn't follow config laws

Added / Updated Values: Breaking Enabled — Option to turn zombies’ block-breaking behavior on or off. Breaking Radius — Sets how far zombies can reach to break blocks around their target. Default Cooldown — The general cooldown between block-breaking attempts for all blocks. Per-Block Cooldowns — Specific cooldowns for individual blocks, so some blocks can take longer or shorter to break than others. Behavior Changes: Zombies will now follow the configured rules instead of hardcoded values. Any block not listed under per-block cooldowns will use the default cooldown.

Block Breaking System Zombies can now break blocks in their way. Config-controlled with block_breaking.enabled, radius, cooldown_ticks, breakable_blocks. Noise & Light Awareness (Aggro Triggers) Zombies aggro when players: Sprint Eat food Shoot bows Place torches/light blocks Smarter Targeting (Memory System) Zombies remember their last seen target for a few seconds instead of instantly dropping aggro. Nearby zombies aggro when one spots a player. Leader/Follow Behavior Each group has a leader Followers move toward their leader when idle. Blood Moon Enhancements Doubles zombie spawn counts. Applies strength buffs. Adds sounds & particles when triggered. Smarter safe spawn location checks. Integrated with time-of-day config (day, night, both).

Fixed a bug caused more bugs fixed them and then my computer blew up (Jk I'm will be busy soon and will make better changlog later)

1. Priority Targeting of Players Zombies constantly scan for nearby players within a 50-block radius. They calculate distance to each player and target the closest uninfected player. Fully infected players are ignored, effectively removing them from the zombie’s threat list. If no uninfected players are nearby, the zombie stops targeting anyone. Every 10 ticks, the plugin loops through all zombies in all worlds to refresh AI targets and abilities. Zombies check if their current target is still valid, updating movement, potion attacks, or burster effects. This ensures the AI remains responsive and adaptive in real-time. If no valid target exists, zombies reset their target to null, preventing wandering aimlessly or attacking fully infected players. This keeps AI efficient and purposeful, ensuring they always prioritize threats.

Infection System & Mutations Added infection system with configurable infection chance, max infection, and increase per zombie hit. Players now have infection percentage tracked persistently (players.yml). Infection can be visualized with a boss bar showing current infection percentage. Players can be cured partially by consuming golden apples or enchanted golden apples. Infection spreads when infected players kill other players or are killed by zombies. Fully infected players transform into mutated zombies with one of several mutation types: tank, charger, assassin, blight, burster, spitter, frost. Mutations provide unique attributes: max health, potion effects, and visual indicators. Fully infected players display custom name (Infected <player>). Infection persists across player disconnects and server restarts. Added support for sunlight protection on zombies (prevent natural burning). Infection system and mutation features are fully configurable in config.yml. Added /zombieapocalypse and /za command handler. Commands implemented: /za reload – reloads config and infection settings. /za info – shows current day, mutation rate, blood moon status, and active zombies per type. /za spawn <type> – spawn custom zombies (normal, tank, charger, assassin, blight, burster, spitter, frost) near player. /za forcebloodmoon – triggers blood moon event immediately. Command permissions: zombieapocalypse.admin for reload and force blood moon. zombieapocalypse.spawn for spawning zombies. Spawned zombies now scale base speed and damage with current day (speed and damage multipliers applied). Added Burster ability: gains speed boost when near a player (<5 blocks). Modified AI for creatures to run from fully infected players (similar to running from zombies). Blight and Frost zombie attacks now apply unique potion effects on players: blight → poison effect. frost → slowness effect. Zombies spawned via commands now fully support mutation-based attributes and visual setup. Boss bar dynamically updates infection progress and changes color when fully infected.
