Class BlockFormEvent

All Implemented Interfaces:
Direct Known Subclasses:

public class BlockFormEvent extends BlockGrowEvent
Called when a block is formed or spreads based on world conditions.

Use BlockSpreadEvent to catch blocks that actually spread and don't just "randomly" form.


  • Snow forming due to a snow storm.
  • Ice forming in a snowy Biome like Taiga or Tundra.
  • Obsidian / Cobblestone forming due to contact with water.
  • Concrete forming due to mixing of concrete powder and water.

If a Block Form event is cancelled, the block will not be formed.
