Storage & Selling

Virtual storage

Each spawner holds what it produces. A player opens the spawner, sees the stack of each item and either withdraws it or sells it on the spot. Nothing lies on the ground, so a busy farm costs the server one block entity rather than three hundred item entities.

virtual-storage:
  default: true
  force-default: false
  permission: uxmspawners.settings.togglestorage

Turning storage off for a spawner makes it drop items into the world instead, which is what you want for the ITEM-mode spawners you actually want players to walk through.

XP storage

XP is kept the same way and withdrawn from the menu.

xp-storage:
  default: true
  force-default: false
  permission: uxmspawners.settings.togglexp

disable-xp-drops in config.yml stops spawner mobs dropping XP on the floor at all.

Limits

modules/storage_limits.yml caps how much a spawner can hold, per item and for XP, with permission tiers on top:

storage-limit:
  enabled: true
  default: 2000
  xpLimit: 10000
  permissions:
    uxmspawners-storage1: 5000
    uxmspawners-storage2: 10000
    uxmspawners-storage3: 20000
  xpPermissions:
    uxmspawners-xpstorage1: 15000
    uxmspawners-xpstorage2: 20000
    uxmspawners-xpstorage3: 25000

Keep the lists in ascending order. A player holding several of these gets the highest.

Selling

The sell button is per spawner type (spawnerInfo.sell_button) and prices come from itemPrices.priceProvider:

Money is paid through Vault. modules/multipliers.yml adds permission-based sell multipliers:

multipliers:
  enabled: true
  permissions:
    uxmspawners-1-25x: 1.25
    uxmspawners-1-50x: 1.50

Ascending order again, highest wins. modules/other.yml → title-messages decides whether the money and XP amounts are shown as a title on screen.
