ZombieSMP brings your server to life by unleashing a genuine zombie apocalypse. Designed for creative server owners and unique SMP adventures, this plugin transforms nighttime into a high-stakes survival challenge with deep community interaction.

Features:

• Quadruple zombie spawns at night for real danger and chaos.
• Beds explode if players try to sleep, just like in the Nether.
• If a player is attacked by a zombie at night or by an infected player, they become a zombie for 10 minutes with permanent, fully configurable slowness.
• Deep LuckPerms integration: when infected, a player's current permission group is saved and replaced with a new "zombie" group. After the effect ends (or is cleared by staff), the previous group is restored automatically.
• Track how many times each player has become a zombie with the %zombies% placeholder, usable in scoreboard, tab, or hologram.
• Infected players cannot attack or be attacked by other zombies or infected players. Zombie-on-zombie combat is fully blocked to encourage cooperation between the infected.
• Infection and transformation are fully customizable: choose how many zombie/player hits before a transformation happens using a config option, perfect for events or balancing SMP difficulty.
• When a player is infected, a fully customizable "ding" sound and title display (like BedWars-style "ZOMBIEE") for unmistakable feedback. Both the text and subtitle can be changed in config.yml.
• Infected players burn in direct sunlight, just like real zombies, taking half a heart of damage per second. Wearing any helmet prevents burning.
• Infection reward system: when an infected player infects a human, the server can execute a configurable command (e.g., give the infector a diamond). Fully customizable and can be toggled on/off.
• Staff can infect any player manually with /zombies add player, or cure them at any time with /zombies clear player.
• All messages, durations, multipliers, slowness level, infection titles, rewards, and commands are fully configurable in config.yml.
• Optionally, you can choose if the infection timer runs while the player is offline.
• Permanent slowness applied to infected players cannot be removed by drinking milk or other means (except plugin cure).
• Infection counter and state are saved to disk, so data persists through restarts.

To set up:

1. Dependencies required: LuckPerms for group management (absolutely necessary), PlaceholderAPI if you want to show %zombies% in scoreboard, tab, or holograms, and PaperMC 1.21.x.
2. To create the zombie group, use the following LuckPerms commands in your console:
   /lp creategroup zombie
3. Optionally, set a prefix so infected players stand out:
   /lp group zombie meta setprefix "&2[Zombie] "
4. You can also adjust the group's permissions if you want to give infected players special limitations or abilities.
5. Edit the config.yml file in the ZombieSMP folder to fully customize infection times, multipliers, messages, commands, slowness level, hit requirements, infection titles, sun damage, and reward system.
6. When infected, a player is moved to the zombie group and receives permanent slowness (as configured). After the timer runs out or when cured using /zombies clear, their old group and permissions are restored.
7. Use %zombies% in any PlaceholderAPI-compatible plugin (scoreboard, tab, hologram, chat) to show each player's infection count.

ZombieSMP is made for servers that want to create real tension and unique zombie infection gameplay, perfect for special events, new SMP challenges, or creative game modes.
