đĻ Concrete Powder Block
Concrete Powder Block hardens into a solid block when it touches water. This happens:
- On placement â if placed directly in water or next to water.
- After falling â if it lands in water or next to water (common combo with
falling_block). - On neighbor update â if water flows next to an already-placed powder block.
When water is detected on any side, the block fires a BlockFormEvent and replaces itself with solid_block.
Exampleâ
blocks:
default:gunpowder_block:
behavior:
type: concrete_powder_block
solid_block: default:solid_gunpowder_block # the block to turn into when hardening (required)

info
solid_block accepts any valid block ID or full block state (e.g. minecraft:stone[axis=y]). It is required â if omitted the block can't harden.
