Technical Changes

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

Data Pack Version 79

• Dialogs can now be configured 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 added 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 the 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 the 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 accommodate 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 the same format as click_event on text components (but with action replaced with type).

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 an id from a 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

A release candidate is always the final version before an update is officially launched. Based on past major updates, the Minecraft Summer Game Drop should be less than two weeks away.
