• Moved Template:Cd from Template:Cd to Template:Cd.

  • All methods for Template:Cd.
• Changed Template:Cd method on Template:Cd to now take a variant of either a string or Template:Cd.
• Added Template:Cd and Template:Cd APIs to the Template:Cd class.
• Added Template:Cd property to the Template:Cd class.

Blocks

• The Template:Cd component underwent a schema change:
• It is now a JSON object with two fields Template:Cd and Template:Cd.
• Template:Cd is a required string field expecting an HEX representation of the RGB, prefixed with a # character.
• Template:Cd is a string field that multiplies the color with a predefined tint. Supported values are Template:Cd, Template:Cd, Template:Cd, Template:Cd, Template:Cd and Template:Cd.
• The old schema format is still supported for convenience.

Components

• Added the Template:Cd component which determines if a new block can replace the existing block at a particular position. If the component is not added to a block it is not replaceable.
• Multiple components that used effect durations can now be set to Template:Cd including:
  • Template:Cd: Template:Cd
  • Template:Cd: Template:Cd in the Template:Cd list
  • Template:Cd: Template:Cd
  • Template:Cd: Template:Cd, Template:Cd, and Template:Cd can now all use Template:Cd
  • Template:Cd: Template:Cd in the Template:Cd list
  • Template:Cd: Template:Cd in the Template:Cd list
  • Template:Cd: Template:Cd

JSON Events

• The parameter Template:Cd in the Template:Cd event can now be set to Template:Cd.

Sounds

• Added support for entity sound variants:
  • Entity sounds now have a Template:Cd field which defines sound variants based on the runtime entity
  • Template:Cd has a Template:Cd field reading a Molang expression returning a string to select sound variant (eg: querying an enum entity property).
  • Template:Cd has a Template:Cd field which contains key-value pairs of a variant identifier and the sound events it overrides.
  • When playing a sound for an entity we first try to calculate their variant and see if that variant overrides the sound event, if not we play the sound form the base entity. If that fails we fall back to the existing logic of running from Template:Cd.

Experimental

These additions and changes are accessible by enabling the "Beta APIs", "Render Dragon Features for Creators", and "Drop 1 2025" experimental toggles.

Template:Fixes Other

• Placing a block in liquid, and then placing another block next to your first block in liquid will no longer replace your second placed block for a moment causing you to fall into the liquid.

• Fixed a crash that would occur on Xbox if you pressed "Cancel" in the Xbox UI when converting a world or importing a world from Retail to Preview
• In Server Authoritative movement, when Players receive a movement correction it will use the current Player speed instead of a generic one, this should give a better experience.
