NexaSpawners - Premium Virtual Spawner Economy Plugin
NexaSpawners is a next-generation virtual spawner economy plugin built for modern SMP, Lifesteal, SkyBlock and economy-based Minecraft servers.
It keeps the real spawner block visible in the world while moving production, storage, XP, selling, boosters, upgrades and management into configurable virtual systems. This means players still get the familiar spawner experience, but your server avoids unnecessary mob entity spam and gains a safer, cleaner and more scalable economy layer.
NexaSpawners is not just a simple spawner menu. It is a complete spawner economy platform with virtual production, state-preserving spawner items, SQL-backed storage, sell tools, boosters, corruption protection, trust systems, admin panels, migration tools, editor surfaces, hooks, events and addon APIs.
MAIN FEATURES
Virtual Spawner Engine
- Real spawner blocks stay visible in the world
- Virtual production system instead of relying on live mob spawning
- Configurable VIRTUAL and CLASSIC spawner modes
- Production calculated by interval, stack size and drop tables
- Round-robin ticking with per-cycle and per-chunk budgets
- Offline production limits
- Storage capacity based on spawner type, stack bonuses and boosters
- Virtual XP storage
- Optional autokill behavior for classic/fallback spawner mobs
- Registered virtual spawners can cancel nearby vanilla spawner mob spawning
- Configurable mob nerfing options
- Safe break handling with transaction locks
- Optional Silk Touch requirements
- Configurable explosion protection
- Natural vanilla spawner conversion tools
- Spawn egg type-changing support
- Stack splitting and stack merging behavior
Stateful Spawner Items
NexaSpawners preserves spawner data when players break and move spawners.
When a registered spawner is broken, the returned item can keep:
- Spawner UUID
- Owner data
- Storage contents
- Stored XP
- Stack amount
- Active boosters with paused remaining time
- Permanent upgrade levels
- Trusted players
- Lock state
- Corruption value
- Internal history identity
This makes spawner movement safer and more valuable for real economy servers. Players do not lose progress just because they move their base, reorganize a farm or transfer a spawner.
Storage, Selling and Economy
NexaSpawners includes a full virtual storage and selling system.
- Per-spawner virtual item storage
- GUI storage view
- Take one stack, take all, drop all and sell all actions
- Storage collect and sell commands
- Configurable total capacity, per-drop capacity and per-stack bonuses
- Overflow modes: pause production, void excess output or overfill storage
- Inventory overflow handling
- Explicit sell prices per drop
- External shop price provider support
- Addon price provider support
- Sell booster multipliers
- SellWand and SellAxe support
- Permission-based sell multipliers
- Vault economy deposits
- AutoSell booster support
- Chat, title, actionbar and sound feedback
- Pre/post sell events
- Durable SQL operation journal for sell, sellwand, sellaxe, autosell and admin force-sell flows
The sell pipeline is designed for economy safety. NexaSpawners writes a durable operation journal before money is applied, then tracks completed and failed persistence states so staff can review and recover risky operations.
Boosters
NexaSpawners includes configurable booster systems for advanced server economies.
Implemented booster types include:
- Speed boosters
- Loot boosters
- XP boosters
- Sell boosters
- Storage boosters
- Corruption protection boosters
- AutoSell boosters
Boosters can be item-based, persistent, removable, paused and returned with remaining time. The plugin also supports global boosters and personal boosters, allowing server owners to run events, crate rewards, timed boosts or premium economy perks.
Booster features include:
- Config-driven booster definitions
- Persistent booster duration
- Expired booster cleanup
- Active booster slot limits
- Global booster commands
- Personal booster commands
- SQL persistence for personal/global boosters
- Optional custom item provider support
- Placeholder support inside booster item names and lore
- Command hooks for crate, market, broadcast or webhook integrations
Corruption Anti-AFK System
NexaSpawners includes a corruption system to help protect server economies from fully unattended production abuse.
Corruption can increase through production and can be configured to slow, stop or lock specific spawner actions. Players can clean corruption through GUI actions, Vault costs or corruption cleaner items.
Corruption features include:
- Production-based corruption growth
- Configurable action locks
- GUI cleaning
- Cleaner item support
- Vault cleaning cost support
