Unbreakable Blocks Plugin

now version 1.21.11

Added the ability to make any block type unbreakable via /unbreakable add [material] or by looking at a block. Persistent block ownership: track who placed each unbreakable block; data saved across reloads and restarts. Reinforced blocks: configurable hit points before a block can be broken. Explosion protection: TNT, Creepers, Wither blasts, and other explosions do not destroy unbreakable blocks. Piston protection: unbreakable blocks cannot be pushed or pulled by pistons. Feedback system: configurable particle and sound effects when a player attempts to break an unbreakable block. Trust system: /unbreakable trust <player> and /unbreakable untrust <player> for temporary access. Added /unbreakable check command to inspect block ownership and status. Full command suite with granular permissions: add, remove, list, check, trust, untrust. Admin bypass permission: unbreakable.bypass allows breaking any unbreakable block. Placeholder Protected Regions support for future expansion. Fully persistent configuration for unbreakable blocks, reinforced HP, feedback settings, and ownership data.
