Enter your world in single player. Enter the command /admin. Enter the command /debug. Your screen should look something like this: Notice the dungeon ID that I circled. This one says 65532. Notice that as you move your cursor around, different ID's show up. Take note of these. After moving the cursor over my entire ship, I get the IDs: 65531 65532 65535 These numbers may be different for you if you are a different race. I haven't tried it. I am of the human race in Starbound. After finding the ID numbers, type: /settileprotection 65531 true /settileprotection 65532 true /settileprotection 65535 true Again these are the ID numbers of my ship. Yours may be different. Exit debug mode: /debug Exit admin mode: /admin Attempt to destroy everything on your ship with your matter manipulator. If something breaks, enter /admin mode, then /debug mode again, put your cursor over the area that broke, and note that ID number down that was circled in the picture above. Enter the protection command for that ID number. /settileprotection ##### true then exit debug and admin mode again and repeat the process until you can't break anything on your ship. This effect persists into multiplayer. I have tested this with an irl friend of mine and we are unable to break anything on eachothers ship. Now, as seen in the picture above, I block off all of my loot with blocks while in multiplayer. I myself cannot even access it. I do this because with doors, anyone can still open them even though they are protected. They can still be interacted with. The same applies to containers. They cannot be destroyed, but they CAN BE interacted with and looted. The only container I leave out in the open has fuel in it. I suggest going to a remote planet, hiding your treasure there, and then when you are done doing multiplayer, leave your party and grab it all up. Go back to your single player world and enter the same commands you did before except change true to false. Again making sure you are in admin mode. Now you can get into your treasure room and put away all your loot, while not being part of a party. Going back to multiplayer may be necessary to grab up the rest of your loot, but you will not be a part of a party anymore, and people will be unable to teleport to your now unprotected ship. The only way anyone can get around this is to have admin privileges. Which if your server gives admin privileges to just anybody then you shouldn't be playing there anyway. If you have a jerk admin or moderator then yeah, they could turn protections off on your ship. But this will stop most of the headache against the general user. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I hope some people found this useful. I have played on dozens of Minecraft servers and I don't even bother with them if I cannot protect my builds, because I have had my home griefed before. No one likes wasting time. EVEN STILL please note: ALWAYS for the love of God, MAKE BACKUPS of your storage folder somewhat regularly. On my Windows 7 computer, mine is located by default at: C:\Program Files (x86)\Steam\SteamApps\common\Starbound\storage Even if this protection is fool proof, there are bugs in the game. Save files can get corrupted one way or the other. I still would do this, especially if you have spent 90+ hours in the game like I have. That's me being perhaps overly cautious. But I do it without regrets. Just a heads up.
