UltimateVirtualSpawner

Virtual mob spawners for Minecraft servers.

A managed spawner never spawns a real mob. Every cycle it rolls its drop table and deposits the result straight into its own virtual storage, so a 100,000-stack spawner farm costs the server nothing in entities.

What it does

• Stackable spawners — up to MAX_STACK_PER_BLOCK spawners in a single block. Sneak-place to place a whole item stack, sneak-break to take out up to 64 at once, /spawner split to break a stack item apart.
• Virtual storage — a real, clickable container GUI per spawner. Left-click, right-click and shift-click behave the way they do in a vanilla chest, plus shift-right to toggle a filter.
• Drop filters — per-spawner, per-drop toggles, with enable-all and disable-all shortcuts.
• XP generation — spawners accumulate XP alongside items; players claim it from the main menu.
• Built-in economy — balances stored in this plugin's own database, with /balance, /baltop, /pay and /eco. No economy plugin required; optionally published to Vault so other plugins share the same money.
• Selling — sell stored loot for money, with a confirmation screen showing the payout and per-permission sell multipliers.
• Hopper extraction — optionally pull stored loot into a hopper placed under the spawner.
• Anti-ESP — spawners outside a player's reveal radius (or behind blocks) are sent as camouflage blocks, so X-ray clients cannot map other players' farms.
• Admin panel — browse every managed spawner per world and teleport to it.
• Folia-native — all world access goes through the region scheduler; no main-thread assumptions.
