Can someone please explain the /setblock command?

I want a command block to set a block if there is clay but not set a block if there is black wool. How do I do this?

The syntax for setblock is as follows:

/setblock <x> <y> <z> <blockName>

The setblock command can only be used for one block at a time. It cannot replace that block based on what it previously was.

Since your situation requires you to (presumably) fill more than one block, the /fill command would be more appropriate.

The syntax for filling only blocks of a certain type is as follows:

/fill [x1] [y1] [z1] [x2] [y2] [z2] [BlockToFill] 0 replace [BlockToBeReplaced]

So to replace all clay in the world, you would use this command:

/fill [x1] [y1] [z1] [x2] [y2] [z2] [BlockToFill] 0 replace minecraft:clay

Simply replace the x y z x2 y2 z2 values with the co-ordinates to fill, and [BlockToFill] with the ID of the block you wish to replace the clay with.

    Might be worth noting that the 0 in your fill commands is the dataValue (damage value) of the block you set, which is important for filling with logs or wool.

  • ... until Minecraft 1.13, where that data value is removed, and logs and wool are entirely separate blocks.
