Hardcore Multiplayer (Spigot Plugin)

Overview

This plugin adds a shared hardcore experience for Minecraft servers. If one player dies, the entire world is deleted, and a new world is created with a random seed.

Features

• Shared Hardcore Mode: Players share a single hardcore experience. If any player dies, the current world is removed, and a new one is generated.
• Random World Generation: Each time the world is recreated, it uses a new random seed.
• Async World Generation: Worlds are generated in the background, so the server stays responsive while the next run is prepared.
• Lives System: Configure how many deaths the group gets before the world is reset.
• Built-in Portals: Nether and End portals are linked to the session worlds — no Multiverse required.
• Lang Support: Every message is configurable in the config.yml file.

Installation

1. Download the plugin .jar file and place it in your server's plugins directory.
2. Restart your server to load the plugin and generate the default config.yml.
3. Set lobby-world in config.yml to the name of the world players wait in (defaults to world), then run /hcmp reload.

Usage

Commands

All commands require the hardcoremp.command permission. Aliases: /hardcoremp, /hmp.

Command	Description
/hcmp help	Show the command list.
/hcmp info	Show details of the world you are in: seed, difficulty, spawn, time, weather, world type and remaining lives.
/hcmp reload	Reload config.yml without restarting the server.

How a run works

1. Start the server. Players wait in the lobby world while the game world is generated in the background.
2. Once the world is ready, players are moved into the shared hardcore session (overworld, nether and end).
3. When a player dies, the group loses a life. Players listed in user-bypass-list do not consume lives.
4. When lives reach zero, players are moved to spectator mode while the session worlds are deleted, a new world is generated with a random seed, and everyone is teleported into it.

Configuration

Key options in config.yml:

Option	Description
lobby-world	Name of the world players wait in while the game world is generated.
remove-old-worlds	Delete the old world folders after a reset.
motd	Show the session status in the server MOTD.
user-bypass-list	Players whose deaths do not trigger the death event.
offline-player-inventory-clear	Clear the inventory and ender chest of offline players on reset.
max-lives	Deaths allowed before the world is reset.

create-time and reset-id are written by the plugin. Do not edit them manually.
