# CancelBlockUpdate<\/p>\n
CancelBlockUpdate is a Paper server plugin that lets administrators suppress selected block updates on a per-world basis.<\/p>\n
It is designed for servers that need finer control over block physics, block spread, fluid movement, redstone updates, piston movement, and other common update-related mechanics without globally affecting every world.<\/p>\n
## Features<\/p>\n
– Per-world block update control
\n– Suppress updates only for configured block types
\n– Compatible with Multiverse-style multi-world servers
\n– LuckPerms-compatible permission nodes
\n– YAML configuration
\n– `\/cbu` command system
\n– Smart tab completion
\n– Runtime reload support
\n– Configurable chat message prefix
\n– English and Chinese language files
\n– Player messages follow the player’s Minecraft client language
\n– Console messages default to English<\/p>\n
## Requirements<\/p>\n
– Paper `26.1.1`
\n– Java `25`<\/p>\n
Optional integrations:<\/p>\n
– Multiverse-Core
\n– LuckPerms<\/p>\n
CancelBlockUpdate does not require Multiverse-Core or LuckPerms to run, but it is designed to work cleanly alongside them.<\/p>\n
## How It Works<\/p>\n
The plugin keeps normal block updates enabled by default.<\/p>\n
When you run:<\/p>\n
“`text
\n\/cbu world disable
\n“`<\/p>\n
the current world will start suppressing updates for the block types listed in the configuration.<\/p>\n
When you run:<\/p>\n
“`text
\n\/cbu world enable
\n“`<\/p>\n
the current world returns to normal block update behavior.<\/p>\n
This means you can disable selected block updates in one world while leaving other worlds untouched.<\/p>\n
## Commands<\/p>\n
| Command | Description | Examples:<\/p>\n “`text ## Permissions<\/p>\n | Permission | Description | All permissions use Bukkit’s standard permission system, so they can be managed directly through LuckPerms.<\/p>\n ## Configuration<\/p>\n Default config:<\/p>\n “`yaml default-block-updates-enabled: true suppressed-blocks: worlds: {} Example world configuration:<\/p>\n “`yaml `block-updates-enabled: false` means configured block updates will be cancelled in that world.<\/p>\n ## Locale Support<\/p>\n Locale files are stored in:<\/p>\n “`text Included languages:<\/p>\n – `en_US.yml` Chinese clients receive Chinese messages. Other clients and the console use English fallback messages.<\/p>\n ## Notes<\/p>\n CancelBlockUpdate targets common block update paths exposed through the Paper\/Bukkit API, including physics, spread, growth, fading, forming, fluid flow, piston movement, redstone current changes, leaf decay, burning, and entity-driven block changes.<\/p>\n Some very specific internal Minecraft update behavior may depend on what the server exposes through events.<\/p>\n","protected":false},"excerpt":{"rendered":" Per-world block update suppression plugin for Paper servers, with Multiverse support, LuckPerms-compatible permissions, YAML config, i18n, and \/cbu commands.<\/p>\n","protected":false},"featured_media":36796,"template":"","meta":{"_minecraft_slug":"cancelblockupdate","_minecraft_project_id":"iCIBf92Q","_minecraft_author":"DrSmoothl","_minecraft_license":"AGPL-3.0-or-later","_minecraft_downloads":2,"_minecraft_follows":0,"_minecraft_client_side":"unsupported","_minecraft_server_side":"required","_minecraft_storage_type":"zip","_minecraft_archive_name":"cancelblockupdate.zip","_minecraft_size_bytes":16898,"_minecraft_version_count":1,"_minecraft_updated_at":"2026-05-16T12:13:33.855176Z","_minecraft_date_created":"2026-05-12T00:32:40.065138Z","_minecraft_date_modified":"2026-05-09T05:34:41.812263Z","_minecraft_project_url":"https:\/\/modrinth.com\/mod\/cancelblockupdate","_minecraft_icon_attachment_id":36796,"_minecraft_imported_at":"2026-06-01T18:26:25+00:00","_minecraft_import_hash":"b0b1ddb7ceaf75643307e9ab62c34898","_minecraft_versions":"","_minecraft_links":"","_minecraft_gallery":"","_minecraft_api_metadata":""},"mod_category":[124,127],"mod_loader":[130,132],"minecraft_version":[167],"class_list":["post-36795","mod","type-mod","status-publish","has-post-thumbnail","hentry","mod_category-bukkit","mod_category-paper","mod_loader-bukkit","mod_loader-paper","minecraft_version-26-1-1"],"yoast_head":"\n
