server.properties file, there is this configuration value called
allow-flight with a default value of
false. According to the Minecraft Wiki:
Allows users to use flight on your server while in Survival mode, if they have a mod that provides flight installed. With allow-flight enabled, griefers will possibly be more common, because it will make their work easier. In Creative mode this has no effect.
- false - Flight is not allowed (players in air for at least 5 seconds will be kicked).
- true - Flight is allowed, and used if the player has a fly mod installed.
Can this value be edited without restarting the server? If so, how?
