'''Step 4''': Now we get into the masks! Yippee! To refer to the different mask go to the 317 Protocol [https://rswiki.moparisthebest.com/index.php?title=317_Protocol#Player_Updating Player Update Masks].
So we first make an integer named 'mask' and make a field named 'flags' that equals the otherPlayer update flags.
* Appearance: If we have a flag that equals our apperance flag and a force appearance is enabled. Our mask |= 0x1.
* Animation: If we have a flag that equals our animation flag, our mask |= 0x2.
* Chat: If we have a flag that equals our chat flag and !no chat, our mask |= 0x40.
* Graphics: If we have a flag that equals our graphics flag, our mask |= 0x100.
So after that we check if the bitmask would overflow a byte. Like so:
{| border=2
! Method
|-
| if (mask >= 0x100)
|-
|}
If so, our mask |= 0x80 and we write as a short and indicate we have done so.
{| border=2
! Method
|-
| block.put((byte) (mask & 0xFF))
|-
| block.put((byte) (mask >> 8))
|-
|}
If not, we write it as a byte.
{| border=2
! Method
|-
| block.put((byte) (mask))
|-
|}
And then we get into what the flags contain.
* Apperance: If our flag gets the update flag appearance or the appearance is forced we go to method > Player Appearance Update.
* Animation: If our flag gets the update flag animation, we go to the method > Animation Update.
* Graphics: If our flag gets the update flag graphics, we go to method > Graphics Update.
* Chat: If our flag gets the update flag chat and !noChat, we go to method > Chat Update.
Then we convert the block builder to a packet.
{| border=2
! Method
|-
| Packet blockPacket = block.toPacket()
|-
|}
Now it is over, cache the block if we can and finally append the block at the end.
=== Explaining (1) ===
The update block packet holds update blocks and is sent after the main packet.
