Usage

Main Commands

/voxelcleaner

Alias: /vc
Clears (hollows) a rectangular area in front of the player.

/voxelcleaner <width> <height> <depth>
/voxelcleaner <width> <height> <depth> <material>
/voxelcleaner <width> <height> <depth> <material> <force>
/voxelcleaner <width> <height> <depth> <material> <force> <loot>

Parameters:

  • width – Inner width of the area
  • height – Inner height of the area
  • depth – Inner depth of the area
  • material (optional) – Block used for the outer shell
  • force (optional, boolean) – Removes protected blocks
  • loot (optional, boolean) – Collects drops into chests

/voxelroom

Alias: /vr
Creates a fully built room with walls, floor, and ceiling.

/voxelroom <width> <height> <depth> <walls> <floor> <ceiling>
/voxelroom <width> <height> <depth> <walls> <floor> <ceiling> <force>
/voxelroom <width> <height> <depth> <walls> <floor> <ceiling> <force> <loot>

Parameters:

  • width – Inner width of the room
  • height – Inner height of the room
  • depth – Inner depth of the room
  • walls – Wall block
  • floor – Floor block
  • ceiling – Ceiling block
  • force (optional, boolean) – Overrides protected blocks
  • loot (optional, boolean) – Collects removed blocks into chests

History Commands

/voxelundo

Alias: /vcu
Undoes the last voxel action.

/voxelundo
/voxelundo <count>

/voxelredo

Alias: /vcr
Redoes previously undone voxel actions.

/voxelredo
/voxelredo <count>

/voxelhistory

Alias: /vch
Displays the command history for the current player.

/voxelhistory
/voxelhistory <count>

Notes

  • All commands are player-only (cannot be executed from console).
  • Undo/redo works per player and per dimension.
  • force and loot default to false if not specified.
  • Protected blocks (block entities, spawners) are preserved unless force = true.

Configuration

All constants are centralized in VoxelConfig.java. Notable configuration options:

public static final int MAX_W = 64;
public static final int MAX_H = 64;
public static final int MAX_D = 64;
public static final int MAX_ACTIONS_PER_PLAYER = 10;
public static final int MAX_HISTORY_LINES = 20;
public static final String TIMEZONE = "America/New_York";

Adjust these values to fine-tune player limits, history depth, and size constraints.

Examples

# Hollow out a 10x5x10 area using default material
/voxelcleaner 10 5 10

# Hollow out a 10x5x10 area with stone shell and collect loot
/voxelcleaner 10 5 10 minecraft:stone true true

# Create a 7x4x7 room using different blocks for walls, floor, and ceiling
/voxelroom 7 4 7 minecraft:oak_planks minecraft:birch_planks minecraft:glass

# Create a 7x4x7 room and override protected blocks
/voxelroom 7 4 7 minecraft:oak_planks minecraft:birch_planks minecraft:glass true

# Undo the last 2 voxel actions
/voxelundo 2

# Redo the last undone voxel action
/voxelredo 1

# View the last 5 voxel actions for the current player
/voxelhistory 5

Troubleshooting

  • ❗ Commands not recognized? Make sure the mod is loaded and you're using the Fabric profile.
  • ❗ Block edits not working? Ensure you're not targeting protected blocks (e.g., spawners, blocks with entities).
  • ❗ Undo stack not working? Check VoxelConfig.MAX_ACTIONS_PER_PLAYER to ensure history is enabled for players.
