Party Window
From Starbounder - Starbound Wiki
The party window keeps track of other players in your party. It shows you their health and energy, a compass pointing in their direction, and the distance they are from you. It will also allow you to inspect them, trade with them, and beam to their ship.
Party of more than 4 players
To be able to have more than 4 players in a party, you need to:
- Change maxTeamSize's property in the server's starbound_server.config file. This will make the server support the chosen amount of players in a team.
- Change the same property in your client configuration file (starbound.config in your game folder's storage directory). This will make the '+' button appear as long as your team isn't 'full' (depending on the amount you chose).
