			Data kept	Byte	Bit mask. 0x01: Keep attributes, 0x02: Keep metadata. Tells which data should be kept on the client side once the player has respawned. In the Notchian implementation, this is context dependent: normal respawns (after death) keep no data; exiting the end poem/credits keeps the attributes; other dimension changes (portals or teleports) keep all data.

Store Cookie (play)

Modifier Data structure:

Field Name	Field Type	Notes
UUID	UUID
Amount	Double	May be positive or negative.
Operation	Byte	See below.

The operation controls how the base value of the modifier is changed.

0: Add/subtract amount
1: Add/subtract amount percent of the current value
2: Multiply by amount percent

All of the 0's are applied first, and then the 1's, and then the 2's.

Entity Effect

Packet ID	State	Bound To	Field Name	Field Type	Notes
0x72	Play	Client	Entity ID	VarInt
			Effect ID	VarInt	See this table.
			Amplifier	Byte	Notchian client displays effect level as Amplifier + 1.
			Duration	VarInt	Duration in ticks. (-1 for infinite)
			Flags	Byte	Bit field, see below.
			Has Factor Data	Boolean	Used in DARKNESS effect
			Factor Codec	NBT Tag	See below

	The following information needs to be added to this page:
	What exact effect does the blend bit flag have on the client? What happens if it is used on effects besides DARKNESS?

Within flags:

0x01: Is ambient - was the effect spawned from a beacon? All beacon-generated effects are ambient. Ambient effects use a different icon in the HUD (blue border rather than gray). If all effects on an entity are ambient, the "Is potion effect ambient" living metadata field should be set to true. Usually should not be enabled.
0x02: Show particles - should all particles from this effect be hidden? Effects with particles hidden are not included in the calculation of the effect color, and are not rendered on the HUD (but are still rendered within the inventory). Usually should be enabled.
0x04: Show icon - should the icon be displayed on the client? Usually should be enabled.
0x08: Blend - should the effect's hard-coded blending be applied? Currently only used in the DARKNESS effect to apply extra void fog and adjust the gamma value for lighting.

~~Factor Data~~

Name	Type	Notes
padding_duration	TAG_INT
factor_start	TAG_FLOAT
factor_target	TAG_FLOAT
factor_current	TAG_FLOAT

-Data Array, Block Light, and Sky Light are given for each block with increasing x coordinates, within rows of increasing z coordinates, within layers of increasing y coordinates.
+=== Living Entity ===
-The global palette encodes a block as 13 bits. It uses the {{Minecraft Wiki|Data values#Block IDs|block ID}} for the first 9 bits, and the block damage value for the last 4 bits. For example, diorite (block ID <code>1</code> for <code>minecraft:stone</code> with damage <code>3</code>) would be encoded as <code>000000001 0011</code>.
+TODO: This has changed to use the PARTICLES attribute

-==== Spawn Player ====
+=== Serverbound ===
-This packet is sent by the server when a player comes into visible range, ''not'' when a player joins.
-This packet must be sent after the [[Protocol#Player List Item|Player List Item]] ([[#Play|Play]], 0x38, clientbound) packet that adds the player data for the client to use when spawning a player. If the Player List Item for the player spawned by this packet is not present when this packet arrives, Notchian clients will not spawn the player entity. The Player List Item packet includes skin/cape data.
-Servers can, however, safely spawn player entities for players not in visible range. The client appears to handle it correctly.
-When in online-mode the UUIDs must be valid and have valid skin blobs, in offline-mode UUID v3 is used.
-For NPCs UUID v2 should be used. Note:
- <+Grum> i will never confirm this as a feature you know that :)
+==== Cookie Response (login) ====
-In an example UUID, <code>xxxxxxxx-xxxx-Yxxx-xxxx-xxxxxxxxxxxx</code>, the UUID version is specified by <code>Y</code>. So, for UUID v3, <code>Y</code> will always be <code>3</code>, and for UUID v2, <code>Y</code> will always be <code>2</code>.
+Response to a [[#Cookie_Request_(login)|Cookie Request (login)]] from the server. The Notchian server only accepts responses of up to 5 kiB in size.

-==== Player Position And Look ====
+==== Login (play) ====
-Updates the player's position on the server.
-If the distance between the last known position of the player on the server and the new position set by this packet is greater than 100 meters, the client will be kicked for “You moved too quickly :( (Hacking?)”.
-Also if the fixed-point number of X or Z is set greater than <code>3.2E7D</code> the client will be kicked for “Illegal position”.
-Yaw is measured in degrees, and does not follow classical trigonometry rules. The unit circle of yaw on the XZ-plane starts at (0, 1) and turns counterclockwise, with 90 at (-1, 0), 180 at (0, -1) and 270 at (1, 0). Additionally, yaw is not clamped to between 0 and 360 degrees; any number is valid, including negative numbers and numbers greater than 360.
-Pitch is measured in degrees, where 0 is looking straight ahead, -90 is looking straight up, and 90 is looking straight down.
-The yaw in degrees of a player standing at point (x0, z0) and looking towards point (x, z) can be calculated with:
- l = x-x0
- w = z-z0
- c = sqrt( l*l + w*w )
- alpha1 = -arcsin(l/c)/PI*180
- alpha2 =  arccos(w/c)/PI*180
- if alpha2 > 90 then
-     yaw = 180 - alpha1
- else
-     yaw = alpha1
-You can get a unit vector from a given yaw/pitch via:
- x = -cos(pitch) * sin(yaw)
- y = -sin(pitch)
- z =  cos(pitch) * cos(yaw)

+* 0x02: Show particles - should all particles from this effect be hidden?  Effects with particles hidden are not included in the calculation of the effect color, and are not rendered on the HUD (but are still rendered within the inventory).  Usually should be enabled.
+* 0x04: Show icon - should the icon be displayed on the client?  Usually should be enabled.

-In normal operation (i.e. placing a block), this packet is sent once, with the values set normally.
+==== Debug Sample Subscription ====
-The Cursor Position X/Y/Z fields (also known as in-block coordinates) are calculated using raytracing. The unit corresponds to one pixel in the default resource pack. For example, let's say a slab is being placed against the south face of a full block. The Cursor Position X will be higher if the player was pointing near the right (east) edge of the face, lower if pointing near the left. The Cursor Position Y will be used to determine whether it will appear as a bottom slab (values 0–7) or as a top slab (values 8–15). The Cursor Position Z should be 15 since the player was looking at the southernmost part of the block.
-This packet has a special case where X, Y, Z, and Direction are all -1. (Note that Y is unsigned so set to 255.) This special packet indicates that the currently held item for the player should have its state updated such as eating food, pulling back bows, using buckets, etc.
-Special note on using buckets: When using buckets, the Notchian client might send two packets: first a normal and then a special case. The first normal packet is sent when you're looking at a block (e.g. the water you want to scoop up). This normal packet does not appear to do anything with a Notchian server. The second, special case packet appears to perform the action — based on current position/orientation and with a distance check — it appears that buckets can only be used within a radius of 6 units.
-==== {{Change||Use Item}} ====
-Sent when pressing the Use Item key (default: right click) with an item in hand.
