Minecraft 1.21.6 Pre-Release 1

Hey! This is the first pre-release of 1.21.6. From now on, you will mostly see us fixing bugs and the release schedule might include more than one pre-release per week. We are on the finish line for the second drop of the year!

Changes

• The Dried Ghast Block now emits a vibration frequency of 11 when its block state changes
• Shearing Saddles, Horse Armor, and Carpets now emits a vibration frequency of 6, along with the Unequip frequency of 4
• The Ambient Dried Ghast sounds are now adjusted under the Blocks sound option instead of the Ambient/Environment option
• A player riding a Happy Ghast can no longer completely fly through a Happy Ghast ridden by another player

Technical Changes

• The Data Pack version is now 79
• The Resource Pack version is now 63

Data Pack Version 79

• Dialogs can now configure if they pause the game and if they close after an action is taken
• Every dialog can now have inputs and can submit information
  • The definition of actions has been changed to accommodate that
  • The dedicated input dialog types have been removed, since they are redundant now
  • The order of elements is:
    • Body
    • Inputs
    • Actions
• The minecraft:custom click event has been expanded to carry full a NBT tag
• A new keybind called "Quick Actions" has been added to allow accessing content-configured dialogs

Quick Actions Keybind

• A new keybind has been addded that allows users to access a set of dialogs
• Default key: G
• This feature is configured by minecraft:quick_actions dialog tag
  • If this tag is empty, the keybind does nothing
  • If this tag has a single element, the keybind will open this dialog
  • If this tag has multiple elements, the keybind will lead to minecraft:quick_actions dialog which (by default) lets user select one of the tag elements
    • If this dialog is removed, the keybind does nothing
• This option is intended to be used in custom content and by servers, so this tag is empty by default

Common Dialog fields

New fields:

• pause - if the dialog screen should pause the game in single-player mode, default: true
• after_action - an additional operation performed on the dialog after click or submit actions, default: close
  • close - closes the dialog and returns to the previous non-dialog screen (if any)
  • none - does nothing, i.e. keeps the current dialog screen open
    • only available if pause is false to avoid locking the game in single-player mode
  • wait_for_response - replace the current dialog with a "Waiting for Response" screen
    • this option is intended to prevent users from sending multiple actions on slow connections
      • servers are expected to eventually replace this screen with a new dialog
    • to avoid accidental locking, a "Back" button will become active after 5 seconds
      • clicking this button will continue as if the dialog was closed (i.e. the game returns to the previous non-dialog screen, if any)
    • The "Waiting for Response" screen will unpause the game in single-player mode to avoid locking the game

Dialog Types

Changed minecraft:multi_action, minecraft:server_links, minecraft:dialog_list

• Replaced field on_cancel with exit_action, holding an optional action
  • If exit_action is present, a button for it will appear in footer, otherwise the footer is not present
  • exit_action is also used for the Escape action

Removed minecraft:simple_input_form

• Since any dialog can now have inputs, this dialog can be replaced by minecraft:notice

Removed minecraft:multi_action_input_form

• Since any dialog can now have inputs, this dialog can be replaced by minecraft:multi_action (without any specified exit_action)

Input Control Types

• To accomodate the new minecraft:custom click event, all inputs will now return either a string or an NBT tag, depending on context

minecraft:text

• Output values:
  • As template substitution: contents without modification
  • As tag: a string tag with contents without modification

minecraft:boolean

• Output values:
  • As template substitution: on_true when checked, on_false when unchecked
  • As tag: 1b when checked, 0b when unchecked

minecraft:number_range

• Output values:
  • As template substitution: text representation of current value
    • Whole numbers will be sent without decimal point
  • As tag: a float tag with current value

Dialog Body Types

Hover and click events on text components within bodies now work as expected

• Click events are handled by the dialog screen like any other action - that means it will also run the after_action

Actions

• The format of actions has been changed due to the merging of plain and input dialogs
• After every action the dialog will always evaluate the contents of the after_action field (see above)

Fields:

• Kept fields: label, tooltip, width
• New field: action (replaces on_click and on_submit) - an action to perform when button is clicked, optional object with fields:
  • type - value from minecraft:dialog_action_type registry
  • <type-specific> - see below, depends on type

Static Dialog Action Types

All existing click_event actions (except for open_file) are included as dialog action types.

Uses same format as click_event on text components (but with action replaced with type) For example, when using show_dialog, entry for action button will look like:

{
    "label": "some label",
    "action": {
        "type": "show_dialog",
        "dialog": "some:id"
    }
}

minecraft:dynamic/run_command Action Type

• This action will build a run_command event using a provided macro template
• The macro will be expanded with string values from all inputs
  • For example, if the macro template is some_command $(some_input), the string value from the input with key of some_input will be used for the template expansion
  • Inputs not used in macro will be ignored, while macro parameters not matching any inputs will be replaced with an empty string

Fields:

• template - a string with a macro template to be interpreted as a command

minecraft:dynamic/custom Action Type

• This method will build a minecraft:custom event using all input values
• All input contents will be sent together inside a compound tag, with tag value of each input put under id from key field of that input
• Additional static fields can be added to payload

Fields:

• additions - fields to be added to payload, optional compound tag
• id - namespaced ID

Resource Pack version 63

• Added oversized_in_gui item model field
• Introduced new player head special model type

Item Models

• Item model definitions now have a boolean field oversized_in_gui which is false by default
  • If true, the item model will be allowed to be bigger than its item slot
  • If false, the item model will be clipped to the item slot size when being rendered in gui
  • This ability of items being rendered outside their slots should not be considered officially supported, it was temporarily restored as an exception since many servers are relying on it
  • At some point in the future we hope to replace it with an officially supported way of achieving similar functionality
• Introduced new item model minecraft:player_head to handle player profile texture loading and rendering
• Removed support for minecraft:profile from minecraft:head

minecraft:player_head special model type

• Renders a player head
• Uses profile from the minecraft:profile component to load a texture. Renders a default texture until the profile texture is fully loaded
• No fields

minecraft:head special model type

• No longer supports profile from minecraft:profile component to load a player texture
• Renders a default player texture when kind is player and no texture override is supplied
• Fields remain unchanged
