FAQ

The plugin disabled itself with “No licence key yet.”

The license field in plugins/AtlasLoader/atlasspawner.yml is empty. Paste your key between the quotes and restart. See Licensing & activation.

There is no economy plugin on this server. What breaks?

Nothing breaks. Any priced action set to VAULT under economy in config.yml (mining, placing, upgrading, stacking, changing, buying a booster, selling) becomes free the moment there is no Vault, or Vault is present but no economy plugin is registered with it. You get a one-time console warning, and every one of those actions keeps working — it simply costs nothing. Selling still works too; it just pays out nothing if sell is one of the free groups.

My spawners aren’t producing anything.

The most common cause is the player gate: a spawner only runs while a player is within its range (an upgrade axis, so a fresh spawner’s range is whatever level 1 gives it). Stand near it, or check that a player really is in range — not just online on the server. If a spawner recently found nobody nearby, it also waits engine.idle-recheck ticks (default 100, five seconds) before it looks again, so give it a moment. See How spawners work.

If the spawner’s store is full and every output.targets entry is set to STOP instead of OVERFLOW, the cycle produces nothing at all rather than partially filling — check that the store is being collected, or that a container it feeds still has room.

Which storage should I use, SQLite or MySQL/MariaDB?

SQLite if this is one server — no setup, and it is the default. MySQL or MariaDB only if you want several servers to share one player’s spawners, whitelist, boosters and returns. If you do, give every server sharing that database its own storage.server name — two servers with the same name will collide. See database.yml.

Does this work on Folia?

Yes — folia-supported: true, and every block and inventory touch happens on the region thread that owns it. The one thing Folia genuinely changes is the /atlasspawner bench dev tool (not shipped in a release build): Folia has no single whole-server tick to measure, so it says so instead of printing a number. Ordinary gameplay is unaffected.

A MOBS-mode farm produces less than the same spawners in DROPS mode.

That is expected, not a bug. DROPS mode never spawns a mob, so it has no cap: a hundred spawners stacked into one block produce exactly what a hundred spread over a field produce. MOBS mode is the vanilla spawner with your upgrade values written onto the block, and vanilla itself stops spawning once enough mobs are already nearby — that ceiling is vanilla’s, and MOBS mode does not remove it. If you want the equal-output promise, use DROPS mode (the type default, and what every shipped type uses).

Can a player rename a spawner in an anvil to change what it is?

No. anvil.prevent-anvil (default true) cancels any anvil click that would move a spawner item into, inside, or out of an anvil at all — not only the renamed result. A spawner’s identity lives in the item’s own data, not in its name, so this exists purely to stop an old renaming trick from other plugins, not because renaming would otherwise do anything.
