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.
| Software | Minecraft range |
|---|---|
| Paper / Spigot / Bukkit | 1.21.10 – 26.2 |
| Folia | 1.21.11 – 26.2 |
Escape hatches live in config.yml under COMPATIBILITY:
STRICT: false — a version string that cannot be parsed is allowed through with a warning
instead of blocking start-up.ENABLED: false — skip the gate entirely and start on any server. Unsupported, no guarantees.MAX_STACK_PER_BLOCK in a single block, sneak-place and
sneak-break to move whole stacks, /spawner split to break a stack apart./balance, /baltop,
/pay and /eco. No economy plugin required; optionally published to Vault so other plugins
share the same money.

Missing keys are back-filled from the packaged defaults on every load, so updating the plugin never wipes customised values.
Money is handled by the plugin itself. ECONOMY.PROVIDER in config.yml picks the backend:
| Mode | Behaviour |
|---|---|
INTERNAL (default) |
Balances live in this plugin's database. Nothing else to install. |
VAULT |
Defer to an external economy plugin (EssentialsX, CMI, …) through Vault. |
AUTO |
Use Vault when an economy provider is registered, otherwise fall back to internal. |
Changing the mode needs a full server restart, not /spawner reload.
With REGISTER_WITH_VAULT: true (the default) and Vault installed, the built-in economy is
published as a Vault provider — so shops, jobs and similar plugins read and write these same
balances instead of the server ending up with two disconnected pots of money. Vault is not
required; without it the economy simply stays internal to this plugin.
Balances are rounded to DECIMAL_PLACES on every change so repeated arithmetic cannot drift into
fractions of a cent, and each player's balance is mutated under its own lock so two concurrent
sells cannot interleave into a lost update.
Both optional:
PROVIDER: VAULT. Selling works without it.uvs expansion.JDBC drivers (SQLite, MySQL) are declared as libraries in plugin.yml and downloaded by the
server on first start, so the plugin jar stays small.
