Rebuild (Premium)

The rebuild option runs a sequence of block builders after a structure is broken. You can place replacement blocks, clear parts of a layout or build a short destruction/reconstruction sequence.

Each step belongs under options.rebuild.build. Use type, not class.

Working example

options:
  rebuild:
    mode: BOTTOM_UP
    delay: 10
    block-delay: 3
    build:
      center:
        order: 0
        type: place
        material: COPPER_BLOCK
        offset: "0 0 0"
      above:
        order: 1
        type: place
        material: COBBLED_DEEPSLATE_SLAB
        offset: "0 1 0"

delay is the initial wait in ticks, and block-delay is the separation between successive steps.

Rebuild modes

Mode	Behavior
INSTANT	All steps are executed after the initial delay.
RANDOM	Steps run in a deterministic shuffled order.
BOTTOM_UP / TOP_DOWN	Sorted by height.
CENTER_OUT / OUTSIDE_IN	Sorted by distance from the center.
LAYER	Steps on the same level run together.
RADIAL	Sorted by horizontal distance from the center.

Use mode: LAYER with direction: TOP_DOWN to build from above. The ordering modes affect the timing, not which blocks are changed.

The build section uses structure builders such as place, destroy and destroylayout. For example, the bundled generator_1.yml contains a rebuild sequence you can adapt.

Add an effect to each step

options:
  rebuild:
    mode: BOTTOM_UP
    delay: 10
    block-delay: 4
    effects:
      type: particle
      particle: END_ROD
      amount: 4
    build:
      base:
        order: 0
        type: place
        material: STONE
        offset: "0 0 0"

Test on a copy of your world first: rebuilding can overwrite blocks, and different protection plugins may react differently to scripted placement. Rebuild is not a general backup/rollback system.
