Server Properties file in NBODE

There are some pointed additions to the server bootup process and features in Noticeably Beta 1.8. These have existed since quite some time before the Alpha 1.0.0 version of NBODE came out.

If you just want to skip ahead, here's a template server properties file to get you started.

New flags in Noticeably Beta 1.8

Private Seed

private-seed=

If set to true, people will not be able to see the seed you used to generate your server world in the debug overlay.
In further toward the future versions of Minecraft, seeing the seed that a server uses by pressing F3 is completely off with no options by default. I don't know how it is in 2026 vanilla Minecraft, but those versions do exist.
This mod gives every server owner the option to hide the seed. This can be useful if you're trying to prevent some kind of stupid exploit that a troll could use to spoil where a Stronghold is or something, I don't know. The client of server players gives their F3 a clear message that states that the seed visibility has been turned off.

Hard Mattress Mode

hard-mattress-mode=

Hard Mattress Mode is the game option where if true, sleeping in a bed will play the animation but when you get out of the bed it will still be night. It makes the day-night cycle more of a threat. However, the option in the server.properties file is not entirely straightforward.
To make your server world file generate with the Hard Mattress Mode setting, put the text true at the end of the hard-mattress-mode= line. But if you don't put anything, not even false, the actual level.dat file in the folder will decide whether Hard Mattress Mode is on instead. The purpose of this stickler was to make it so that the server host can change Hard Mattress Mode to be on or off on the server they run without having to edit the world file, just in case their HMM setting doesn't work out. No other server property in NBODE has this kind of conditionality right now.

Map Features

map-features=

Believe it or not, this flag wasn't a thing in servers running Beta 1.8, even though the feature could be toggled on world creation in singleplayer mode. This behaves as you would expect if you know the meaning of "map features" already. That is, setting it to true will ensure that Villages, Strongholds, and Mineshafts generate naturally inside the world.

Disable Far Structures

disable-far-structures=

Independent of "Map Features", this is a flag you can turn on if you want the original Beta 1.8 structures - edited a bit though they are - but you don't want any of the new generated structures from NBODE. In Alpha 1.0.0 there is only one of these.

And finally...

Authentication servers for Beta 1.8.1 are currently down, and there's not much I can do about that. You might want to set online-mode to false.
