How to Use

Use the command /properties reload to reload the server.properties file (requires permission level 2 or higher). You will see a report of which properties were changed, and which are unsupported.

Supported Properties

As of 1.18, the following properties are supported:

  • allow-flight
  • allow-nether
  • broadcast-console-to-ops
  • broadcast-rcon-to-ops
  • difficulty
  • enable-command-block
  • enable-jmx-monitoring
  • enable-query
  • enable-rcon
  • enable-status
  • enforce-whitelist  [ When enabled, it will kick non-whitelisted players even if the whitelist is disabled. This is consistent with Minecraft's existing inconsistency (for ex. /deop command will do the same). ]
  • entity-broadcast-range-percentage
  • force-gamemode  [ Only affects players who login after the change. Use /defaultgamemode to set game mode for all online players. ]
  • function-permission-level  [ Only takes place after reloading resource packs using /reload ]
  • gamemode  [ Only affects players who login after the change. Use /defaultgamemode to set game mode for all online players. ]
  • hardcore  [ The heart icon and respawn menu will only update for players who login after the change, but respawning itself works as expected. ]
  • max-players  [ Only affects players who try to login after the change. ]
  • max-world-size
  • motd
  • network-compression-threshold  [ Only affects players who login after the change. When changed while a player is logging in, it might cause the connection to be setup incorrectly and cause errors. Be careful. ]
  • online-mode  [ Only affects players who login after the change. ]
  • op-permission-level  [ Works the same as editing server.properties and restarting, i.e. it only applies to users /op'd after the change and does not affect existing operators. ]
  • player-idle-timeout
  • prevent-proxy-connections  [ Only affects players who login after the change. ]
  • pvp
  • query.port
  • rcon.password  [ Any currently connected RCON clients will be disconnected. ]
  • rcon.port  [ Any currently connected RCON clients will be disconnected. ]
  • require-resource-pack  [ Only affects players who login after the change. ]
  • resource-pack  [ Only affects players who login after the change. ]
  • resource-pack-prompt  [ Only affects players who login after the change. ]
  • resource-pack-sha1  [ Only affects players who login after the change. ]
  • simulation-distance
  • spawn-animals
  • spawn-monsters
  • spawn-npcs
  • spawn-protection
  • view-distance
  • white-list

Unsupported Properties

  • generate-structures
  • generator-settings
  • level-name
  • level-seed
  • level-type
  • max-tick-time
  • rate-limit
  • resource-pack-hash  [ Use resource-pack-sha1 instead. ]
  • server-ip
  • server-port
  • snooper-enabled
  • sync-chunk-writes
  • text-filtering-config
  • use-native-transport
