WorldEditBlock data syntax
With all of WorldEdit's commands that take a block argument, you can specify block data. For example, crops determine their growth status using their data value and so you can use this to set the crops' growth.
Block data syntax
All commands that take a block to use support this syntax.
Some blocks use the data values, and data values are valid between 0 and 15 (inclusive) (although not all blocks support the entire range). To specify a block's data, simply append a colon (:) and the value after the block name or ID, as follows.
Information about blocks that use their data value can be found on the Minecraft wiki.
For wool Since v2.15, carpet and stained clay Since v5.5.9 you can also use its color name (i.e.
Sign text is separated by pipe symbols (|) for each line. Spaces must be replaced with underscores (_).
Mob spawner mob type
The mob spawner mob type can be specified after a pipe symbol (|).
Note block pitch
A number of commands that take a "block" parameter really take a pattern. Rather than set one single block, a pattern allows you to set more complex patterns. For example, you can set a pattern where each block has a 10% chance of being brick and a 90% chance of being smooth stone.
Note all commands that take a block parameter support patterns yet (as of writing), but it is planned for all commands to be converted over.
The block probability pattern is specified with a list of block types (which also support the block data syntax mentioned above) with their respective probability.
For a truly random pattern, no probability percentage is needed.
Since v3.0 You can make a copy with the clipboard and use #clipboard or #copy for the pattern to repeat the copy.
