Stacked Spawners & Blocks

Big farms and big resource stockpiles usually mean either lag or an extra stacker plugin to babysit. IgniteSky stacks both spawners and ordinary blocks itself, with merge and split rules that close the dupe holes those external plugins are famous for. There is no separate plugin to install or keep in sync.

Stacked spawners

Right click a placed spawner with a matching spawner item to add it to the stack. A stacked spawner spawns more mobs per cycle, shows a floating count above it, and drops the whole stack when broken, so a player never loses spawners to a misclick.

spawner:
  enabled: true
  max-stack: 64
  # Hard ceiling on mobs spawned in one cycle regardless of stack size (anti-lag).
  spawn-cap-per-cycle: 16

The spawn-cap-per-cycle is the important safety valve: however tall a stack grows, it will never try to spawn more than this many mobs in a single cycle, so a wall of stacked spawners cannot melt a region thread.

Stacked blocks

General block stacking merges matching resource blocks into one counted block with a floating label. Sneak place a listed block onto a matching one (or right click with the block in hand) and the two merge; break it and the entire stack drops back.

stacking:
  enabled: true
  max-stack: 256
  # Require sneaking to merge a placed block, so normal building never stacks by accident.
  require-sneak: true
  blocks:
    - DIAMOND_BLOCK
    - EMERALD_BLOCK
    - GOLD_BLOCK
    - IRON_BLOCK
    - NETHERITE_BLOCK
    - COAL_BLOCK
    - REDSTONE_BLOCK
    - LAPIS_BLOCK
    - COPPER_BLOCK

require-sneak: true keeps everyday building from stacking by accident: you only merge when you mean to. The blocks list is yours to edit; resource blocks are the usual choice. Stacks are stored per coordinate under <data>/stacks, because plain blocks have no data container of their own to hang a count on.
