how to use the fill command in minecraft

Fills all or parts of a region with a specific block.

Syntax [ ]

Java Edition

fill <from> <to> <block> [destroy|hollow|keep|outline|replace]

The fill command also has an optional alternate syntax when using the replace option:

fill <from> <to> <block> replace [<filter>]

Bedrock Edition

fill <from: x y z> <to: x y z> <tileName: Block> [tileData: int] [oldBlockHandling: FillMode]

fill <from: x y z> <to: x y z> <tileName: Block> [blockStates: block states] [oldBlockHandling: FillMode]

The fill command also has an optional alternate syntax for replace mode:

fill <from: x y z> <to: x y z> <tileName: Block> <tileData: int> replace [replaceTileName: Block] [replaceDataValue: int]

fill <from: x y z> <to: x y z> <tileName: Block> <blockStates: block states> replace [replaceTileName: Block] [replaceDataValue: int]

Arguments [ ]

JE: <from>: block_pos and <to>: block_pos
BE: from: x y z: CommandPosition and to: x y z: CommandPosition

Specifies any two opposing corner blocks of the region to be filled (the "fill region").

In Java Edition, it must be a block position composed of <x>, <y> and <z>, each of which must be an integer or a tilde and caret notation. In Bedrock Edition, it must be a three-dimensional coordinates composed of <x>, <y> and <z>, each of which must be a floating-point number or tilde and caret notation.

Block position is the coordinates of the point at the lower northwest corner of a block. Because of this, the lesser coordinates of each axis are on the region boundary, but the greater coordinates are one block from the boundary, and the block volume of the source region is (x_greater - x_lesser + 1) × (y_greater - y_lesser + 1) × (z_greater - z_lesser + 1). For example, 0 0 0 0 0 0 has a 1-block volume, and 0 0 0 1 1 1 and 1 1 1 0 0 0 both identify the same region with an 8-block volume.

JE:<block>: block_state
BE: tileName: Block: Block

Specifies the block to fill the region with.

In Java Edition, it must be in form of block_id[block_states]{data_tags}(does not accept block tags), in which block states and data tags can be omitted when they are not needed. In Bedrock Edition, it must be a block id.

BE: tileData: int: int

Specifies the block data to use for the fill block. Values that are invalid for the specified block id revert to 0. If not specified, defaults to 0.

Must be a 32-bit integer number. It must be between 0 and 65535 (inclusive).

BE: blockStates: block states: BlockStateCommandParam

Specifies the block states to use for the block.

Must be a blockstate argument as ["<state1>":<value1>,"<state2>":<value2>,...]. For example: ["old_leaf_type":"birch","persistent_bit":true].

JE: destroy|hollow|keep|outline|replace
BE: oldBlockHandling: FillMode

destroy - Replaces all blocks (including air) in the fill region with the specified block, dropping the existing blocks (including those that are unchanged) and block contents as entities as if they had been mined with an unenchanted diamond shovel or pickaxe. (Blocks that can be mined only with shears, such as vines, do not drop; neither do liquids.)
hollow - Replaces only the blocks on the outer edge of the fill region with the specified block. Inner blocks are changed to air, dropping their contents as entities but not themselves. If the fill region has no inner blocks (because it is smaller than three blocks in at least one dimension), acts like replace.
keep - Replaces only the air blocks in the fill region with the specified block.
outline - Replaces only the blocks on the outer edge of the fill region with the specified block. Inner blocks are not affected. If the fill region has no inner blocks (because it is smaller than three blocks in at least one dimension), acts like replace.
replace - Replaces all blocks (including air) in the fill region with the specified block, without dropping blocks or block contents as entities. Optionally, instead of specifying a data tag for the replacing block, block ID and data values may be specified to limit which blocks are replaced.

If not specified, defaults to replace.

JE:<filter>: block_predicate
BE: tileName: Block: Block

Specifies the ID of the blocks in the fill region to be replaced. If not specified, replaces all blocks in the fill region.

In Java Edition, it must be in form of block_id[block_states]{data_tags}(accepts block tags), in which block states and data tags can be omitted when they are not needed. In Bedrock Edition, it must be a block id.

BE: tileData: int: int

Specifies the block data to match when finding blocks to clone. Values (bitwise AND 0xFFFF) that are invalid for the specified block id revert to 0. If -1 or not specified, all blocks that match tileName: Block are filled.

Must be a 32-bit integer number. It must be between -2147483648 and 2147483647 (inclusive).
