Physical spawners

Place, stack, break, holograms, offline progress, and lag-safety.

Physical mode places managed spawner blocks that produce into storage instead of flooding the world with entities.

Place and stack

• Permission: 3tspawner.place / 3tspawner.stack
• Default modes.classic.stack-on-place: false — placing deposits one unit; sneak + right-click stacks from hand
• Chunk limit: limits.per-chunk-spawner-limit (default 128)
• Max stack: limits.default-max-stack

Break behavior

config.yml

spawner-break:
  contents: preserve   # preserve | payout | discard
  keep-upgrades: true

• preserve (default) — loot, XP, and upgrades stay on the dropped item
• payout — sell storage + grant XP to the breaker
• discard — wipe contents on break

Holograms

TextDisplay holograms are enabled by default:

config.yml

holograms:
  enabled: true
  offset-y: 1.2
  update-interval-seconds: 1
  lines:
    - "<mob_display> x<stack>"
    - "<sym_diamond> Storage | <used>/<capacity>"
    - "<sym_diamond> XP | <xp>"

Useful placeholders: <mob>, <mob_display>, <stack>, <used>, <capacity>, <xp>, <value>, <interval>, <owner>, <upgrade_speed>, branding symbols.

Set enabled: false or clear lines to disable.

Offline progress

offline-progress:
  enabled: true
  max-duration-minutes: 360
  multiplier: 0.35

Production while the owner is offline is capped and multiplied. Presets change these values.

Lag-safety

lag-safety:
  enabled: true
  tps-threshold: 17.5
  pause-production: false
  slow-production: true
  pause-display-updates: true

When TPS drops below the threshold, production can slow and hologram updates can pause.

Item branding

Customize the physical item under spawner-item in config.yml (MiniMessage display name and lore with <mob>, <stack>, <owner>, etc.).
