NexaSpawners

A virtual spawner economy platform for SMP, Lifesteal and SkyBlock servers: virtual and classic spawner modes, state-preserving items, storage, XP, boosters, upgrades, corruption protection, sell tools, logs, admin panels, editor tools, plugin hooks and database-backed scale.

Platform snapshot

Core economy, state safety and admin control in one flow.

Virtual production fills storage and XP without entity spam. Break/move/place keeps the same state. Admin tools, logs, setup presets, editor actions, sell tools and migrations sit around the same guarded economy loop.

Virtual storage Sell pipeline Boosters & upgrades Stateful items Admin panel Editor Logs Migration

Produce Config intervals, drops, stack count, boosters and upgrades calculate storage, XP and value.

Preserve Breaking a spawner writes storage, XP, boosters, upgrades, trust, lock state and corruption into the item.

Sell & scale Sellwands, autosell, permission multipliers and shop hooks keep payouts configurable.

Operate Panel, editor, setup presets, reports and recovery tools give staff safe control without SQL edits.

Player systems

Player actions stay fast, shared bases stay controlled, and risky moves stay guarded.

Players get direct GUI actions for placing, stacking, selling, boosting, upgrading, sharing and moving spawners. Staff rules sit around the same flow through limits, permissions, protection hooks and transaction locks.

Control surface

One spawner, two control paths.

The player sees fast menu actions. The backend checks ownership, trust, protection, stack math and corruption before anything valuable changes.

Player Flow open -> collect -> sell -> upgrade

Staff Guard limits -> claims -> locks -> logs

State Safety storage + XP + boosters preserved

Virtual production GUI management Classic fallback

Trust Without Full Ownership

Action-based sharing covers open, sell, collect, boost, upgrade, break and modify. Claims and islands can inherit selected actions without handing over the entire spawner.

Movement Keeps Value Portable

Break, move and place flows keep storage, XP, boosters, upgrades, trusted players, corruption and lock state instead of returning a blank vanilla spawner.

Limits Sit On Every Risky Action

World, chunk, player, permission, stack and type limits combine with WorldGuard, Lands, Towny, Factions, HuskClaims and island checks.

Corruption Is Visible, Not Hidden

Anti-AFK challenges, reduced output, cleaner items and action locks make corrupted spawners obvious before they damage the economy flow.

History Follows The Spawner

GUI and action logs show placement, sell, stack, trust, upgrade, lock, XP and corruption activity so abnormal value changes can be reviewed later.

Hooks, database and performance

Built for live economies, busy claims and SQL-backed networks.

NexaSpawners plugs into the server stack around it while keeping high-frequency production away from entity spam. Prices, claims, holograms, databases, migrations and runtime dispatch all get their own guarded path.

Economy hooks Vault, ShopGUIPlus, EconomyShopGUI, ExcellentShop, zShop, custom providers and addon price sources.

Claim checks WorldGuard, GriefPrevention, Lands, Towny, Factions, HuskClaims and skyblock island access rules.

Display layer Hologram providers, native fallback rendering, custom item providers and PlaceholderAPI/MiniPlaceholders output.

Storage layer SQLite, MySQL and MariaDB through HikariCP with schema migrations, WAL pragmas, backups and journals.

Runtime budget Virtual production, round-robin ticking, per-cycle budgets, per-chunk caps and offline production limits.

Operational surface events + reports

API and addons: Bukkit Services, place/break/stack/sell/upgrade/trust/corruption events and addon SPI.

Migration: vanilla scans, competitor importers, backup-before-apply and rollback metadata.

Paper paths: Java 21 baseline, scheduler abstraction and region-style mutations for modern forks.

Ops alerts: Discord-compatible webhooks, lifecycle cleanup tooling and clear hook status output.

Visual previews

Proof surfaces shown one by one.

Visual previews for the parts buyers usually inspect first: the in-game spawner menu, hologram display, spark profile, admin panel and readable config.yml controls.

Main menu

The spawner menu keeps storage, boosters and sell actions visible.

Players can read stack value, storage fill, active multipliers, XP, upgrade state and corruption without opening extra screens. The menu layout stays configurable through YAML items and placeholders.

Hologram display

Spawner status stays readable in-world.

The display layer can show owner, stack, storage value, XP and corruption directly above the spawner so players can inspect state without opening a menu.

Spark profile

Virtual production should look boring in profiler output.

Stable TPS, low cycle cost and no mob entity spam make the virtual production loop easier to validate under load.

Admin panel

Staff control gets a dedicated visual slot.

The admin panel is not a footnote: it has filtering, spawner inspection, teleport, force sell, lock, unlock, delete, export and bulk-confirm workflows for production server support.

config.yml

Config control gets a cleaner showcase row.

The config preview now highlights production budgets, storage overflow, supported modes, sell tool cooldowns and editable menu/message/hook surfaces without hiding the rest of the feature list.

The mode list stays limited to Virtual and Classic.

Feature depth

Less text clutter, more systems buyers care about.

Beyond the screenshots, the operating surface covers state safety, recovery, migration, hooks and automation.

Stateful items

Break, move and place without losing value.

Returned spawner items preserve UUID, owner, storage, XP, boosters, upgrades, trust, lock state and corruption so server economy state survives normal player movement.

Economy recovery

Sell operations are journaled before money moves.

Sell, autosell, sellwand, sellaxe and admin force-sell flows use a durable SQL operation journal so persistence failures can be tracked and recovered.

Setup presets

Server-type presets and editor tools are built in.

DonutSMP, SkyBlock, Lifesteal, Survival and OP economy profiles can be previewed, applied and rolled back with snapshot protection.

Migration

Competitor imports have fixtures and rollback paths.

Known YAML and SQLite-style layouts are scanned through migration adapters, audited in SQL and guarded by backup-before-apply behavior.

Claims and teams

Protection hooks match real server layouts.

Placement and trust can respect WorldGuard, GriefPrevention, Lands, Towny, Factions, HuskClaims and major SkyBlock island providers.

Addon API

External systems can extend the plugin safely.

Bukkit Services, events and addon SPI cover price providers, migration adapters, protection resolvers, hologram providers and booster type providers.

Automation and alerts

Lifecycle cleanup and Discord-compatible webhooks are part of the operating surface.

SuperiorSkyblock2, BentoBox, IridiumSkyblock, Lands, GriefPrevention, Towny, Factions and HuskClaims cleanup paths can be simulated, exported or applied. Sell, admin, migration and corruption events can be forwarded through configurable webhook filters, retry rules and rate limits.

Ready for production

A complete spawner economy layer, not just a spawner menu.

NexaSpawners keeps the visual spawner block players expect, then moves production, storage, selling, upgrades, trust, admin control and migration into systems that are easier to scale, audit and configure.

Visible blocks Players still interact with real placed spawners.

Virtual production Economy output avoids constant mob entity spam.

Recoverable data SQL storage, backups, journals and migration audits.

Server-ready control Menus, messages, hooks, limits and presets stay editable.
