Changes

Mobs

Technical

API - Scripting

• Unhandled rejected promises in scripting now include callstacks when logged.

@minecraft/server 1.18.0

• Renamed Template:Cd to Template:Cd.
• Moved Template:Cd from Template:Cd to Template:Cd.
• Moved Template:Cd from Template:Cd to Template:Cd.
• Moved Template:Cd from Template:Cd to Template:Cd.
• Released Template:Cd, Template:Cd, and Template:Cd to Template:Cd.
• Released Template:Cd to Template:Cd.
• Released Template:Cd, Template:Cd and Template:Cd to Template:Cd.
• Several APIs have been given the Template:Cd permission, which allows them to now be called inside Before Event callbacks.
  • All methods for 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.
• Examples:

<syntaxhighlight lang="c++"> "minecraft:map_color": {

 "color": "#ABCDEF",
 "tint_method": "grass"

} </syntaxhighlight> or <syntaxhighlight lang="c++"> "minecraft:map_color": {

 "color": "#ABCDEF"

} </syntaxhighlight> or <syntaxhighlight lang="c++"> "minecraft:map_color": "#ABCDEF" </syntaxhighlight>

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.

Components

• 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.
• Example:
  • Given a mob with the following property:

<syntaxhighlight lang="c++"> "minecraft:emotional_state": {

 "type": "enum",
 "values": [ "neutral", "angry", "happy", "sad" ],
 "default": "neutral",
 "client_sync": true

} </syntaxhighlight>

• Sound variants can be played by querying the property:

<syntaxhighlight lang="c++"> {

 "entity_sounds": {
   "entities": {
     "test_mob": {
       "volume": 1.0,
       "pitch": 1.0,
       // The base sounds for various events
       "events": {
         "ambient": "mob.test_mob.ambient",
         "death": "mob.test_mob.death",
         "step": {
           "sound": "mob.test_mob.step",
           "volume": 0.8,
           "pitch": 1.0
         },
         "attack": "mob.test_mob.attack"
       },
       "variants": {
           // Key returning the enum string for variants, can use any Molang expression resulting in a string
           "key": "query.property('minecraft:emotional_state')",
           "map": {
             // If a resulting variant key is not handled here then it will use the base sounds
             "neutral": {
               "volume": 1.0,
               "pitch": 1.0,
               "events": {
                 // If an event is not handled in a variant then it will use the base sound
                 "death": "mob.test_mob.death.netural"
               }
             },
             "angry": {
               "volume": 1.0,
               "pitch": 1.0,
               "events": {
                 // Variants can override different events than other variants
                 "death": "mob.test_mob.death.angry",
                 "ambient": "mob.test_mob.ambient.angry"
               }
             }
           }
         }
       }
     }
   }
 }

} </syntaxhighlight>

Fixes

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 mismatch between server and client when continuously building that caused orientation sensitive blocks to sometimes change to the wrong block.
• 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.
• In Server Authoritative movement, when Players receive a downward movement correction it will now use gravity acceleration, this should give a better experience.
• Fix "Reset Random Tick Speed" button not working when editing an existing world on Realms.
• Bundle tooltip no longer flickers for players beyond the first when playing in split screen
• Adjusted Minecoin purchase screen UI to not show stray pixels. Fixed overlapping issue on PS4.

• Fixed an issue where dark forests were missing trees along their northern borders with other biomes.
• Template:Cd and Template:Cd no longer will turn into Template:Cd or Template:Cd when neighbor updates happen. Template:Cd and Template:Cd now will respond to queued ticks without needing to change into another block.
• Fixed an issue where Template:Cd assert failure occurred when flying through biomes during a storm.
• Fixed Template:Cd type of Template:Cd in Template:Cd to generate on top of water and leaf blocks.
