Defining blocks

How do I get the codes for sub items?
SMOOTH_BRICK is for the smooth stone, but how do i get the cracked one? I tried CRACKED_BRICK but that didnt work :/

Any help would be appreciated!

http://jd.bukkit.org/apidocs/org/bukkit/Material.html for a list of block names.

Cracked smooth brick and other variations are data values of smoth brick.
All data values for all items/blocks: http://www.minecraftwiki.net/wiki/Data_value

Depending on what you need it for you can use that data value to get or set the specific type of a block....

For items:

Code:

ItemStack item = new ItemStack(material/typeid, amount, (short)data); // create item with id, amount, data

item.setDurability((short)data); // to set the data value for an item
item.getDurability() // to get the data value from the item
item.getData() // will return a MaterialData class which has a .getData() which returns a byte, I don't recommend it

For blocks is just .getData() and .setData().
