Minecraft Java Version 1.21.9 | Minecraft

 

Minecraft Server Management Protocol

Added a server administration API (JSON-RPC over WebSocket) for devoted servers

• The API is disabled by default and may be enabled in server.properties
  • management-server-enabled=true
  • management-server-host=localhost
  • management-server-port=0
• The API is accessible at ws://: when enabled
• Supports querying and updating of server state (gamers, allowlist, operators, settings, sport guidelines)
• Sends notifications on state modifications (e.g. participant joins, sport rule updates)
• Calling {“id”:1,”method”:”rpc.discover”} returns an API schema containing supported strategies and notifications of the presently working server
• The Data Generator produces an API schema (json-rpc-api-schema.json) within the stories output folder mirroring the contents returned by the rpc.uncover technique
• The API adheres to the JSON-RPC 2.0 specification
• Uses namespaced strategies and the reserved namespaces are minecraft (e.g. minecraft:gamers, minecraft:allowlist/add)
  • Extensible by way of customized namespaces for extra strategies and occasions
• Core technique teams: gamers, allowlist, operators, server (save, cease), server settings, sport guidelines
• Example technique name:
  • Request: {“method”:”minecraft:allowlist/add”,”id”:1,”params”:[[{“name”:”jeb_”}]]}
  • Response: {“jsonrpc”:”2.0″,”id”:1,”result”:[{“id”:”853c80ef-3c37-49fd-aa49-938b674adae6″,”name”:”jeb_”}]}
• Example notification:
  • {“jsonrpc”:”2.0″,”method”:”minecraft:notification/players/joined”,”params”:[{“id”:”853c80ef-3c37-49fd-aa49-938b674adae6″,”name”:”jeb_”}]}
• Example error:
  • Request: {“method”: “minecraft:foo/bar”,”id”: 1}
  • Response: {“jsonrpc”:”2.0″,”id”:1,”result”:{“jsonrpc”:”2.0″,”id”:1,”error”:{“code”:-32601,”message”:”Method not found”,”data”:”Method not found: minecraft:foo/bar”}}}
  • Errors and error codes observe JSON-RPC 2.0 error object format
• Clients should authenticate to entry the API
  • Clients ought to provide an Authorization bearer token header with a server-specific secret
  • The secret is configured in server.properties
    • management-server-secret=
    • The secret ought to be precisely 40 alphanumeric characters (A-Z, a-z, 0-9)
    • The secret might be robotically generated if the server property is empty
    • Unauthorized requests are rejected with 401 Unauthorized
• TLS is enabled by default
  • Can be disabled in server.properties
    • management-server-tls-enabled=false
  • Requires a keystore file to be set in server.properties
    • management-server-tls-keystore=path/to/keystore.p12
  • The keystore file have to be in PKCS12 format
  • Keystore password may be set within the following methods, so as of precedence
    • Environment variable: MINECRAFT_MANAGEMENT_TLS_KEYSTORE_PASSWORD
    • JVM argument: -Dmanagement.tls.keystore.password=
    • Server property: management-server-tls-keystore-password=

Chat Drafts

• Unsent chat messages now get saved as Chat Drafts if the chat was forcibly closed
  • This consists of it being closed by exterior sources akin to dying or a dialog opening, however not the participant deliberately closing their chat
• Any current Chat Draft will get pre-filled into the message field the following time the chat is opened
• Draft textual content has a grayed-out look till absolutely restored
  • Draft textual content may be restored as common textual content by interacting with it:
    • Typing extra textual content
    • Moving the textual content cursor utilizing the arrow keys
    • Clicking it
    • Highlighting it
  • Pressing enter on a Chat Draft previous to it being restored sends it like a standard chat message
  • Pressing backspace on a Chat Draft previous to it being restored deletes it
• Added an choice to the Chat Settings display that permits saving unsent chat messages by default
  • With this feature enabled, unsent messages will at all times get saved as Chat Drafts, even when the participant deliberately closed their chat

Server Code of Conduct

When connecting to a server, a Code of Conduct display can now be proven.

• Accepting the Code of Conduct is required to play on the server
• A checkbox is on the market for not exhibiting the identical Code of Conduct sooner or later
  • If the Code of Conduct modifications, it is going to be proven once more

Server Setup

• A brand new boolean subject has been added to server.properties known as enable-code-of-conduct
  • Setting it to true will make the server search for Code of Conduct recordsdata within the codeofconduct subfolder in the identical folder as server.properties
  • Each file within the folder ought to have the shape .txt and be UTF-8 encoded
    • The language proven will try to match the participant’s language
    • If it does not exist, the en_us Code of Conduct might be used
    • If that additionally does not exist, an arbitrary accessible entry is used

Sounds

• Some sound sliders within the Music & Sound Options now play a preview sound when adjusting the setting exterior a world

Accessibility

• The “Attack/Destroy” and “Use Item/Place Block” key binds are actually toggleable, which means they are often set to both “Hold” or “Toggle” within the Controls display
• Added “Invert Mouse X” choice to the Mouse Settings display, which inverts the mouse x-axis
• Added “Sprint Window” choice to the Controls display, which represents the time window in ticks the place double-tapping the ahead key prompts dash
• Multiple key binds which have the identical key assigned to them can now work collectively, whereas earlier than just one would work
  • For instance, now you can bind D to Jump and Strafe Left to leap and strafe left on the similar time
  • The pink warning for assigning the identical key to a number of key binds is modified to yellow
• The spectator hotbar menu key can now be rebound
  • It is a part of a brand new Spectator class within the Key Binds display, alongside the pre-existing Highlight Players key bind

Changes

• Performance enhancements
• The Chain block has been renamed to “Iron Chain”
• Monster Spawn Eggs now have a tooltip warning when the issue is ready to Peaceful
  • The mob now not spawns for one tick when an try is made to make use of the Spawn Egg
• Changes to world loading and the “Spawn Chunks”
• A dimension that has any participant exercise, forceloaded chunks, lively portals, or Ender Pearls in flight might be thought-about “active” and can hold processing chunks and entities
  • Previously, this might solely apply if a participant was within the dimension or a bit was forceloaded
• Reworked the debug overlay to be much less cluttered and extra configurable
• Players seen within the sport world of the present server are actually at all times proven within the Social Interactions display even when they’re offline
• Players now cease flying when switching from Spectator Mode to Creative Mode if they’re close to the bottom
  • A participant is taken into account to be close to the bottom if there’s a collidable floor (i.e. blocks, Happy Ghasts, boats…) inside 1 block beneath them
  • Flight won’t get disabled if the participant was inside a block or collidable entity
    • This is to forestall gamers from immediately falling by means of the bottom
• Migrated a number of server properties into sport guidelines
• OpenGL 3.3 is now required to play the sport, up from 3.2. This doesn’t change our posted Minimum Requirements

Developer’s Note: We don’t count on the replace to OpenGL model to have an effect on many individuals, if any in any respect. Our posted Minimum Requirement has been OpenGL 4.0 since 2017, and OpenGL 3.3 turned 15 years outdated just lately.

Performance Improvements

• Entity rendering order was improved for considerably higher efficiency
  • You’ll discover a lot smoother gameplay in areas with a lot of mobs, like mob farms
  • FPS gained’t enhance a lot if most of your lag comes from issues apart from entities, like enjoying with excessive render distance whereas not being close to many mobs
• Particles exterior the participant’s view aren’t rendered anymore, which offers a efficiency enchancment in some circumstances

World Loading and Spawn Chunks

• The idea of mounted “Spawn Chunks” has been eliminated
• The sport will be sure that the next chunks are absolutely loaded earlier than the participant joins or the server begins, in the identical manner as spawn chunks previously have been:
  • Chunks loaded by the forceload command
  • Chunks lively on account of portal exercise
  • Thrown Ender Pearls (Singleplayer solely)
  • A small space of chunks across the participant (Singleplayer solely)
  • Chunks required to assign the worldwide world spawn (World creation solely)
• The world loading display now exhibits the chunks that the participant is about to be positioned into, fairly than chunks loaded round world spawn
• The loading display now has a progress bar
  • This progress bar accounts for every kind of chunk loading talked about above

Developer’s Note: Spawn chunks incur a reminiscence and efficiency value for all gamers and have outlived their preliminary technical function of maintaining the spawn space prepared for gamers to rapidly be part of into.

However, we additionally wish to acknowledge that spawn chunks have enabled a large number of intelligent contraptions and farms all through the years, so merely eradicating them with out having different mechanics within the sport allow these designs was by no means an choice.

We consider that the area of interest held by spawn chunks has now been stuffed by various strategies of chunk loading, akin to utilizing portals or ender pearls, significantly with the modifications on this snapshot to how the sport masses these chunks earlier than the world begins ticking.
