Registries are repositories of data that contain entries pertaining to certain aspects of the game, such as the world, the player, among others.

The ability for the server to send customized registries to the client was introduced in 1.16.3, which allows for a great deal of customization over certain features of the game.

Overview

The server sends these registries to the client via Registry Data packet during the configuration phase.

Packet ID State Bound To Field Name Field Type Notes
Varies Configuration Client
Registry ID Identifier
Entry Count VarInt Number of entries in the following array.
Entries Entry ID Array Identifier
Has Data Boolean Whether the entry has any data following.
Data NBT Entry data. Only present if Has Data is true.

The structure of the entries' data depends on the registry specified in the packet. The structure for each available registry is defined below.

Throughout the configuration phase, the server will send multiple Registry Data packets, each one pertaining to a different registry.

Client/Server Exchange

In order to save bandwidth, the server omits the data for entries pertaining to a data pack that is mutually supported by both the client and server. The exchange is as follows:

  1. SC: Clientbound Known Packs
  2. CS: Serverbound Known Packs
  3. Server computes the mutually supported data packs
  4. SC: Multiple Registry Data (excluding mutually supported data)


Warning.png The ordering in which the entries of a registry are sent defines the numeric ID that they will be assigned to. It is essential to maintain consistency between server and client, since many parts of the protocol reference these entries by their ID. The client will disconnect upon receiving a reference to a non-existing entry.

Available Registries

The current release specification allows for nine different registries to be sent to the client. A brief explanation of each of them is presented below, along with the format of their entries' element field.

Fields marked in __ blue represent data for server-side exclusive operations, and thus have no visible impact on the client.

Armor Trim Material

The minecraft:trim_material registry. It defines various visual properties of trim materials in armors.

Name Type Meaning Values
asset_name String Tag The trim color model to be rendered on top of the armor.

The Notchian client uses the corresponding asset located at trims/color_palettes.

Example: "minecraft:amethyst".
ingredient String Tag The ingredient used.

This has the visual effect of showing the trimmed armor model on the Smithing Table when the correct item is placed.

Example: "minecraft:copper_ingot".
item_model_index Float Tag Color index of the trim on the armor item when in the inventory. Default values vary between 0.1 and 1.0.
override_armor_materials Optional Compound Tag Asset for different types of armor materials, which overrides the value specified in the asset_name field.

The Notchian client uses this to give a darker color shade when a trim material is applied to armor of the same material, such as iron applied to iron armor.

The key can be either:
  • leather
  • chainmail
  • iron
  • gold
  • diamond
  • turtle
  • netherite

The value accepts the same values as asset_name.

description Compound Tag or String Tag The name of the trim material to be displayed on the armor tool-tip.

Any styling used in this component is also applied to the trim pattern description.

See Text formatting.

Armor Trim Pattern

The minecraft:trim_pattern registry. It defines various visual properties of trim patterns in armors.

Huh.png The following information needs to be added to this page:
The decal field seems to exist to prevent overlapping between the armor model and the trim model. What exact effect does it have?
Name Type Meaning Values
asset_id String Tag The trim pattern model to be rendered on top of the armor.

The Notchian client uses the corresponding asset located at trims/models/armor.

Example: "minecraft:coast".
template_item String Tag The template item used for this trim.

This has the visual effect of showing the trimmed armor model on the Smithing Table when the correct item is placed.

Example: "minecraft:coast_armor_trim_smithing_template".
description Compound Tag or String Tag The name of the trim pattern to be displayed on the armor tool-tip. See Text formatting.
decal Byte Tag Whether this trim is a decal. 1: true, 0: false.

The minecraft:banner_pattern registry. It defines the textures for different banner patterns.

Name Type Meaning Values
asset_id String Tag The texture of the pattern.

The Notchian client uses the corresponding asset located at textures/entity/banner or textures/entity/shield, depending on the case.

Example: "minecraft:diagonal_left".
translation_key String Tag The translation key representing the banner pattern, shown in the item's tooltip.

It is appended to the banner color when used, resulting in <translation_key>.<color>.

Example: "block.minecraft.banner.diagonal_left.blue", which translates to "Blue Per Bend Sinister".

Affects foliage and grass color if they are not explicitly set.

The default values vary between 0.0 and 1.0.
