AntiLavaCast

Anti

Prevents high altitude lava placement to stop lava casting on Paper 1.21.x.

Features

  • Cancels lava bucket placement, flow or both if it is more than the configured height above natural ground.
  • Uses CoreProtect history (when available) to identify player-placed blocks for accurate ground detection.
  • Logs a server alert when a placement is blocked.
  • Supports live config reload and runtime toggling.
  • Lava casting attribution, optional logs will tell you who tried to place lava and where.
  • Maintains natural world lava flow.

[AntiLavaCast] Blocked lava placement by CevAPI at -85,164,-29 (heightAboveGround=96, groundY=68)

Requirements

  • Paper 1.21.x
  • Java 21+

Install

  1. Download the jar.
  2. Drop the jar into your server plugins folder.
  3. Start the server to generate the config.

Commands

  • /lavacast reload
  • /lavacast enable
  • /lavacast disable
  • /lavacast setheight <blocks>
  • /lavacast drop <on|off> on allows dropping
  • /lavacast flow <on|off> on allows flowing
  • /lavacast logs <on|off> on logs blocked placements
  • /lavacast coreprotect <on|off> toggles CoreProtect integration
  • /lavacast coreprotectlookback <seconds|1m|2h|7d|4w> sets how far back CoreProtect history is searched
  • /lavacast mark <radius> marks nearby blocks as player-placed for height checks (max radius 100)

Permissions

lavacast.admin (default: op)

Config

plugins/AntiLavaCast/config.yml

max-height-above-ground: 20
enabled: true
allow-lava-drop: false
allow-lava-flow: false
log-blocked-placements: true
coreprotect-enabled: true
coreprotect-lookback-seconds: 31536000

Notes

  • The ground scan ignores player-placed blocks; when CoreProtect is available it will also treat historical placements as player-placed.
  • Use /lavacast mark <radius> around old builds to mark them as player-placed if CoreProtect is not available.
  • Marked blocks are stored on disk in plugins/AntiLavaCast/marks and persist across restarts.
  • When CoreProtect is enabled and detected, mark storage is disabled and lookups rely on CoreProtect instead.

1.0.3Релиз26.1, 26.1.1, 26.1.2 · 26 апреля 2026 г.
  • Fixed startup error on some 1.21.11 forks where AntiLavaCast could fail to register events due to missing nested class references at runtime.
  • Refactored internal storage/cache helper classes to top-level classes for more robust classloading across server implementations.
  • Improved startup logging when CoreProtect is unavailable, disabled, or incompatible.
1.0.2Релиз1.21.9, 1.21.10, 1.21.11 · 23 января 2026 г.

Added

  • CoreProtect integration to detect historical player-placed blocks, with cache and configurable lookback.
  • /lavacast coreprotect and /lavacast coreprotectlookback commands.
  • Disk-backed mark storage per chunk when CoreProtect is unavailable.
  • /lavacast mark radius command to manually mark nearby blocks as player-based for height checks (max 100)

Changed

  • Lava flow blocking now applies only to player-placed lava; natural lava flows normally.
  • Replaced in‑memory placed‑block tracking with disk‑backed per‑chunk mark files (used by /lavacast mark) when CoreProtect isn’t available.
1.0.1Релиз1.21.9, 1.21.10, 1.21.11 · 15 января 2026 г.
  • Added toggle for logging
  • Added attribution for lava casting to logs
