Technical

Minecraft:API

• Template:Cd API (water, lava, potion, snow) has been replaced with Template:Cd.
• Moved Template:Cd from Template:Cd to Template:Cd.

Minecraft:Commands

• Added new overloads for the Template:Cmd command which allows you to clear a queued function:
  • Template:Cmd - Clears all queued functions matching the given name.
  • Template:Cmd - Clears all queued functions that are scheduled as Template:Cd by name.
  • Template:Cmd - Clears all queued functions that are scheduled as Template:Cd by ticking area name (and optionally also checks function name too).

Components

• The Template:Cd field has been added to the Template:Cd component, allowing to define how an entity is restricted to its home position:
  • Its values are:
    • Template:Cd, which poses no restriction.
    • Template:Cd, which restricts randomized movement around the home position.
    • Template:Cd, which restricts any kind of movement around the home position.
  • The Template:Cd value is currently in Template:Cd and is planned to be fully released at a later date.
  • Entities that have moved too far from their home will always be able to move closer to it if prompted.
  • The radius of the restriction is still specified with Template:Cd.
  • Entities with a format version prior to Template:Cd will be upgraded to use the new field in a way that preserves their existing behavior.
• Added the Template:Cd component, which prevents entities from changing dimension through portals.
  • In Vanilla content, this is used by the Ender Dragon, the fishing hook, and some projectiles.
• Added the Template:Cd component, entities with this component will never be saved. In Vanilla content, this is currently used for the fishing hook.

Entity components

• Template:Cd is no longer usable if it is missing a projectile definition and will now throw a content error if so.

Entity event responses

• Added the Template:Cd entity event response, which allows the entity to execute an event on the block at its home position:
  • The Template:Cd field allows to specify the event to execute.
  • For this to work properly, the entity must have a Template:Cd component with a set home position.
