zNxPiglinRush

🔥 zNxPiglinRush

A multi-block Nether spawner framework — boost mob spawns on any block type, with wave mode, live statistics, spawn heatmap, custom loot and full Folia support.

Vanilla already spawns Zombified Piglins above magma blocks in the Nether, but the rate is painfully slow. zNxPiglinRush hooks into every natural spawn, fires multiple extra spawns in the surrounding area, and gives you a complete toolset to monitor, tune and maximise your farms.

✨ Features

• Multi-block spawner framework — configure any block type as a spawner with its own mob, rates and loot. Magma block for gold, soul sand for Wither Skeletons, netherrack for Magma Cubes — all at once
• Two spawn strategies — Standard: immediate extra spawns per trigger. Wave mode: accumulate credits and fire scaled burst waves with progressive scaling
• Custom loot injection — per-spawner drop rules with configurable chance and amounts, injected directly into vanilla death drops
• Spawn statistics — session, total (SQLite-persisted across restarts), hourly ring buffer and per-mob breakdown via /pr stats
• Spawn heatmap — /pr heatmap [radius] toggles a live particle overlay above tracked blocks, coloured blue → yellow → red by spawn density
• TPS diagnostics — async TPS monitor with configurable alert threshold, in-game op warnings and a /pr diagnostics performance report
• Config updater — automatically migrates old config files to the current schema on startup, preserving all your values and creating a timestamped backup
• PlaceholderAPI — 8 placeholders for scoreboards and tab lists
• Folia-native — two scheduler implementations (FoliaSchedulerService / BukkitSchedulerService) selected at runtime, zero issues on region-threaded servers
• Async update checker — Modrinth API v2, clickable in-game notification for ops on join
• Zero NMS — pure Bukkit/Spigot/Paper API, no reflection in hot paths
• Live reload — /pr reload applies all config and registry changes with no restart

🚀 Quick Start

📉 If TPS drops, lower spawn-count or raise spawn-cooldown first.

❓ FAQ

Does this affect overworld magma blocks? No. The plugin fires only when vanilla already triggers a spawn — in the Nether on magma blocks. Overworld magma blocks don't trigger natural piglin spawns, so the plugin has no effect there.

Does it break vanilla spawn rules? The initial vanilla spawn check (light level, mob caps) still runs normally. Extra spawns respect the max-nearby-entities cap configured per block. Global server mob caps in paper.yml / spigot.yml / bukkit.yml still apply.

What is wave mode? When enabled on a block, each vanilla trigger adds a credit to that block's counter. Every wave-cooldown ticks the engine fires a burst: credits × spawn-count mobs (capped at wave-size), with a progressive bonus for consecutive waves. Good for dramatic bursts rather than a constant stream.

Compatible with other spawn plugins? Generally yes — zNxPiglinRush only reacts to events that already passed vanilla's own checks, with no NMS or spawner modifications.

What happens when I update from an old version? The built-in Config Updater detects your old config, creates a timestamped backup, migrates your values to the new schema and fills any new keys with sensible defaults. You don't need to touch anything manually.
