Configuration

By default, Spyglass Astronomy Sync disables most /sga:admin commands. This behavior can be changed in the
configuration file, located at config/spyglass-astronomy-sync.json.

Default configuration:

{
  "allow_admin_commands": false
}
  • Set allow_admin_commands to true to allow all /sga:admin commands for every player. Note that players with
    permission level 2 or higher will bypass this setting.
  • The configuration file is only read at server startup. Restart the server after making changes for them to take
    effect.

Dependencies

To use Spyglass Astronomy Sync, the following are required:

Both the server and the client must have Spyglass Astronomy Sync installed for the synchronization to take effect.
