Zombies Break & Build

Configuration

• Added /zbb config commands for viewing, editing, resetting and reloading the configuration directly in-game.
• Added wildcard and exclusion support to entity/block lists:
  • minecraft:*
  • *:zombie
  • *:*
  • !minecraft:creeper
  • @monster
• Replaced applyToAllMonsters / additionalEntityIdList with the more flexible affectedEntityIdList. The default is ["@monster"].
• Config entries referencing IDs from currently unavailable mods are now preserved in the file and simply ignored until those IDs become available.
• Invalid config files are preserved as .broken, and backups are created when overwriting an existing config.

Building

• Build blocks can now be configured per dimension.
  • Overworld: dirt by default.
  • Nether: netherrack by default.
  • End: end stone by default.
  • Other dimensions use stone as the default fallback.
• Added per-mob build block overrides, which take priority over dimension settings.
• Improved bridge building, including cardinal directions, diagonal movement and mobs with non-standard hitbox sizes.
• Mobs trying to climb toward a higher target can now break blocks obstructing the climb instead of simply giving up.
• Added individual switches for the four main AI tactics:
  • height adjustment;
  • bridge building;
  • obstacle clearing;
  • dangerous block mitigation.

Targeting and AI

• Added continueSeeingTargetsThroughBlocksLimit, allowing the maximum wall thickness for retaining an existing target to be configured separately from finding a new target.
• Reworked solid-block counting for through-wall targeting, including diagonal rays and block-boundary cases.
• Improved stuck detection and break/build activation when normal pathfinding cannot reach the target.
• Mobs no longer immediately start modifying blocks during short periods where no path is available.
• AI transient state is reset when a mob changes or loses its target, preventing behavior from a previous target from leaking into the next one.
• Failed build/break actions are no longer treated as successful actions.
• Mobs no longer attempts to break or scan blocks in unloaded chunks.

Block breaking and balance

• Reworked block health calculation. Block health is now calculated from configurable hardness exponent and multiplier values.
• Added per-block health overrides with blockHealthOverrideMap.
• Added maximumBreakableBlockHardness.
• Reworked tool and mob-size damage multipliers to use configurable exponents.
• Removed the old hard cap on tool destroy speed.
• Improved block crack updates and cleanup.

Block restoration

• Pending broken-block restoration and mob-built-block disappearance now persist across world/server restarts.
• Added a periodic colored marker particle showing positions where broken blocks are waiting to reappear.
• Restoring a broken block no longer destroys a solid block that was placed in that position afterwards. The newer block is preserved and the original stored block is recovered as an item instead.
• Restoration now handles replaceable blocks and ZBB-built tracked blocks more safely.
• Improved recovery when a block-breaking attempt fails.
• Mob-built disappearing blocks now preserve and restore block-entity NBT in addition to the old block state.
• Improved behavior across chunk unload/reload and cleaned up stale disappearing-block visuals.

Falling blocks

• Added support for ZBB-built falling blocks such as sand and gravel.
  • Disappearance tracking follows the falling block to its landing position while preserving the original timer.
  • Stored block damage also follows falling blocks instead of remaining at the original position.

Configuration compatibility note

The config file is now named zombies-break-build.toml instead of zombies-break-&-build.toml, and several configuration fields were replaced or renamed. Existing 1.6.3 configurations require manual migration when updating to this version.
