Structure Block

Structure blocks are unobtainable blocks that the developers use to create structures.

Obtaining
The structure block is only available using the command.

Usage
When obtained with the command, structure blocks do not have any use in game, and emit a light level of 14 (same as torches). However, they are used internally by developers to create structures. They were used to create the end city dungeon structures.

When used internally by developers, the structure block has four modes.
 * D, data - for chest markers and other blocks that require data
 * S, save - build structure in world, tell the block where it is and it saves it to file (default)
 * L, load - loads saved structure files
 * C, corner - for automatic size calculation

The structure block shows outline of the structure it relates to in white, and can rotate/mirror blocks.

Data values
The structure block has a ID name of  and a ID number of 255. It contain an additional data field which determines which variant is used.
