How to change your server's settings (server.properties)

Where it is

server.properties sits in the server's main folder. Change it while the server is stopped, or restart afterwards: the server reads it only when it starts, and may overwrite your edits if it's running.

On Jump, the common settings are in Settings in the panel, and you can edit the whole file in Files.

The settings people change most

• `gamemode`: survival, creative, adventure or spectator for new players. Existing players keep theirs; change them with /gamemode.
• `difficulty`: peaceful, easy, normal or hard. Also changeable live with /difficulty hard.
• `max-players`: how many can be online at once.
• `pvp`: false stops players hurting each other.
• `motd`: the line shown under your server in the list.
• `white-list`: true lets only whitelisted players join.
• `hardcore`: one life; dead players become spectators.
• `spawn-protection`: the radius around spawn that only ops can build in (set 0 to turn it off).
• `view-distance` and `simulation-distance`: how far players see and how far the world is active. Lower them if the server lags.

Changing the seed or world type

level-seed and level-type (for example a flat or amplified world) only apply when a world is generated. Changing them does nothing to an existing world. Set them, then make a new world: on Jump, Reset world in Settings, which backs up first on paid plans. To keep the old world, download it first.

Changes you can make with commands instead

• /gamerule keepInventory true: keep items on death.
• /gamerule playersSleepingPercentage 1: one player sleeping skips the night.
• /gamerule doFireTick false: fire doesn't spread.
• /difficulty, /defaultgamemode and /setworldspawn change settings without a restart.

The server.properties guide lists every common setting and its default.
