🧱 Brick-MapProtect

Lock down your maps. Let players build freely.
A lightweight Paper/Spigot plugin that stops regular players from tearing up your original map, while still letting them place and break their own blocks.

✨ What it does

Only players in Creative mode can break the original blocks of a protected map. Everyone in Survival/Adventure can still build, and break anything players have placed — but the original terrain stays intact. Perfect for minigame lobbies, parkour maps, hub worlds, and gen-raiding arenas.

Action (on a protected map)	Creative mode	Survival · `allow-placing: true`	Survival · `allow-placing: false`
Break an original map block	✅	❌	❌
Place a block	✅	✅	❌
Break a player-placed block	✅	✅	✅

Note: breaking original blocks is gated on game mode, not op status — an opped player in Survival still can't break the map. Use /gamemode creative to edit.

Worlds that aren't in your protected list are left completely untouched.

Anti-grief extras (on by default, configurable): flowing water & lava can't wash away or destroy original map blocks, and fire/lava can't burn them either.

🚀 Installation

Download Brick-MapProtect-<version>.jar from the Releases page.
Drop it into your server's plugins/ folder.
Restart the server (or run /reload confirm).
Edit plugins/Brick-MapProtect/config.yml, then run /mapprotect reload.

Requires: a Paper or Spigot server running Minecraft 1.21.x on Java 21.

⚙️ Configuration

# Which maps (worlds) should be protected?
#   - List exact world folder names, or use "*" for every world.
#   - Worlds not listed are left completely untouched.
protected-worlds:
  - world
  - world_nether
  - world_the_end

# Can regular players place blocks on protected maps?
#   true  = players can place (and later break their own blocks)
#   false = players cannot place any blocks (creative players always can)
allow-placing: true

# Stop flowing water/lava from destroying original map blocks
protect-from-liquids: true
# Stop fire/lava from burning original map blocks
protect-from-fire: true

# Wipe all player-placed blocks on restart (arena reset)?
#   true = map is restored to original state each startup
#   false = player builds persist across restarts (default)
clear-placed-on-restart: false

# Messages (supports & colour codes)
deny-break-message: "&cYou must be in creative mode to break blocks in this map."
deny-place-message: "&cBlock placing is disabled on this map."

🎮 Commands & Permissions

Command	Description	Permission
`/mapprotect reload`	Reload the config without restarting	`mapprotect.admin`

Permission	Description	Default
`mapprotect.bypass`	Explicit override to break/place anything without creative mode	`false`
`mapprotect.admin`	Use `/mapprotect` commands	`op`

🔧 How it works

Every block a player places is recorded by its exact location (world:x:y:z) and persisted to placed-blocks.yml, so the data survives restarts. When someone tries to break a block, the plugin allows it only if that location is a known player-placed block (or the player is exempt). Anything else is part of the original map and is protected.
