==== NBT ====
+
No changes so far.
−
 
 
−
The NBT specification was changed so that the root tag is no longer required to be a [[NBT#Specification:compound_tag|Compound Tag]] when sent over the network.
 
−
 
 
−
Presently in the pre-release, only [[NBT#Specification:compound_tag|Compound Tag]] and [[NBT#Specification:string_tag|String Tag]] types are used as root, but the Notchian server/client implementation is able to handle [[NBT#Specification|NBT Tags]] of any type.
 
−
 
 
−
==== Chat ====
 
−
 
 
−
The [[Chat]] type is now serialized as a [[NBT#Specification|NBT Tag]] instead of a JSON String, unless explicitly stated otherwise.

| Encoded as a [[NBT|NBT Tag]], with the type of tag used depending on the case:
 
−
* As a [[NBT#Specification:string_tag|String Tag]]: For components only containing text (no styling, no events etc.).
 
−
* As a [[NBT#Specification:compound_tag|Compound Tag]]: Every other case.

Result can be one of the following values:
+
* 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 [[Entity_metadata#Living Entity|"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.
 +
* {{change||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.}}

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
Huh.png 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.
