== New/modified data types ==
 
 
=== Entity Metadata ===
 
 
Note that entity metadata is a totally distinct concept from block metadata.  It is not required to send all metadata fields, or even any metadata fields, so long as the terminating entry is correctly sent.
 
 
Entity Metadata is an array of entries, each of which looks like the following:
 
 
{| class="wikitable"
 
! Name
 
! Type
 
! Meaning
 
|-
 
| Index
 
| Unsigned Byte
 
| Unique index key determining the meaning of the following value, see the table below. If this is <code>0xff</code> then the it is the end of the Entity Metadata array and no more is read.
 
|-
 
| Type
 
| Optional Byte Enum
 
| Only if Index is not <code>0xff</code>; the type of the index, see the table below

If the flag is set to true:
 
* The amount if items in Slot B is descreased by one.
 
* A item stack created from the provided identifier and data will be put in Slot A.
 
 
Otherwise:
 
* The amount if items in Slot B is increased by one if not empty, otherwise will a new stack be created from the provided identifier and data.
 
* The item in Slot A will be cleared.
 
 
In both cases will the crafting grid be updated and a Confirm Transaction packet send back to the client, with the window id and action number send by the client.
