A GamePanel schedule warns the players with say, saves the world with save-all, then restarts the server at the time you pick.
GamePanelSystemSchedulesCreate, pick Blank Schedule, Continue, then the name, frequency and time, and Create Schedule.
On the schedule page, Create Task adds an action. Add them in this order, with the Time Offset (seconds) shown:
Send command
say Server restart in 15 minutes, offset 0.Send command
say Server restart in 5 minutes, offset 600.Send command
say Server restart in 1 minute, offset 240.Send command
save-all, offset 50.Send power action, Restart the server, offset 10.
Minecraft server schedule: three messages, the save, then the restart Trigger runs it right away to try it, restart included: the messages show in the chat, prefixed with [Server].
Common errors
- The server restarts around 05:15 for a schedule at 05:00: each offset counts from the previous action. To restart at 05:00, schedule it at 04:45.
- Every 6 hours: in Advanced, set the minute to
0and the hour to*/6.
