Minecraft-Server-Properties-Reload/README.md

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.

  • Only affects players who login after the change.
  • Use /defaultgamemode to set game mode for all online players.
