Changes a block to another block.

• Java Edition

setblock <pos> <block> [destroy|keep|replace|strict]

• Bedrock Edition

setblock <position: x y z> <tileName: Block> <blockStates: block states> [destroy|keep|replace]

setblock <position: x y z> <tileName: Block> [destroy|keep|replace]

JE: <pos>: block_pos
BE: position: x y z: CommandPosition

Specifies the position of the block to be changed.

In Java Edition, 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, must be a three-dimensional coordinates composed of <X>, <Y> and <Z>, each of which must be a single-precision floating-point number or tilde and caret notation.

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

Specifies the new block.

In Java Edition, must be in the format 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, must be a block id.

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].

destroy|keep|replace and destroy|keep|replace|strict

Specifies how to handle the block change. Must be one of:

• destroy — The old block drops both itself and its contents (as if destroyed by a player). Plays the appropriate block breaking noise.
• keep — Only air blocks are changed (non-air blocks are unchanged).
• replace — The old block drops neither itself nor any contents. Plays no sound.
• strict — Place blocks as-is without triggering block updates and shape updates.

If not specified, defaults to replace.
