About this project

What does Block Collapse add?

Block Collapse

Bring structural failure to your builds. Block Collapse checks nearby blocks when you place or break a block and turns blocks that have lost support into falling blocks.

Features

  • Nearby blocks are checked after block placement and breaking.
  • Ordinary blocks use a horizontal support search. By default, blocks can collapse when their nearest supported column is 7 or more blocks away.
  • Blocks with custom support behavior, such as torches, are excluded from the structural search. They can still break normally if their supporting block falls.
  • Block entities and vanilla falling blocks can fall when the block directly below has an empty collision shape, including water.
  • Server settings limit the number of collapses per tick and the number of positions checked during a support search.

Requirements

  • Minecraft 1.21.1
  • NeoForge 21.1.235 or newer

Configuration

Server settings are stored in config/blockcollapse-server.toml.

  • maxCollapsePerTick (default: 100): maximum number of blocks moved into falling entities per tick.
  • maxSearchNodes (default: 64): maximum number of positions checked during a support search.

The structural distance threshold defaults to 7 and can be set with the MAX_DISTANCE environment variable when the mod starts. It is not currently an in-game config option.

Compatibility

Block entities use Minecraft's vanilla falling-block behavior. Their inventories or other data may not be preserved in every situation.

Support Development

Block Collapse is completely free to download and use.
