BlockDoom is the ultimate multiplayer survival challenge plugin designed for Minecraft Paper 1.20.4. It introduces a relentless, high-stakes game mode where time is your greatest enemy.

As a global countdown ticks in the ActionBar, tension mounts. Every 60 seconds, BlockDoom samples the environment around active players, randomly selecting a naturally generated block material. A dramatic title announces the target block, and 5 seconds later, every single natural instance of that block across the loaded world disintegrates into smoke and dust.

Once a block material is erased, it is logged into an irreversible registry and can never be selected again. If STONE or DIRT vanishes, caves collapse and floating islands remain. If trees disintegrate, wood becomes priceless. The chaos continues mercilessly until your players either defeat the Ender Dragon or survival becomes mathematically impossible!

Key Features

• ️ Player Build Protection: Blocks placed by your players are tracked in high-speed chunk memory and protected. Custom bases and structures stay safe while the natural world crumbles around them!
• ️ Immersive In-Game GUI (/blockdoom ui): A beautiful chest menu allowing server operators to instantly adjust countdown timers, deletion speeds, scan radiuses, and manage the block exclusion blacklist with intuitive clicks.
• Auto-Reloading: Tweak settings on the fly via UI or commands. Changes sync instantly across all active game loops without restarting your server.
• ⚡ Zero Lag Architecture: Engineered specifically for high-performance Paper servers. Uses asynchronous chunk snapshot scanning, batched main-thread deletion queues, and Persistent Data Container (PDC) chunk NBT tagging to keep server TPS at a flawless 20.0.
• Per-Dimension Isolation: Overworld deletions are completely isolated from the Nether and End.
