Disable base building entirely
The master switch for building. Turn it on and nobody can construct anything any more.
scum.DisableBaseBuilding=False
What does this setting do?
This switch removes building from the game completely. No foundation, no wall, no flag – not even for admins.
Mind the direction: the value is called Disable, so on means building is forbidden. That is the most common mix-up with this key, because nearly every other switch reads the other way round.
There are exactly two sensible reasons for it. The first is a pure roleplay or event server where only prepared locations should be used. The second is an emergency brake: if your world file has slowed down under the weight of too many elements, this switch stops it getting worse while you clean up.
For anything else the finer tools are the better choice. The element limit per flag, the no-build zones and the decay rate let you keep building on a short leash without banning it.
Which value suits my server?
Off. Building often is the actual content on a PvE server.
Off. Without bases there is nothing to defend and nothing to raid.
Off, with strict limits instead. A ban takes more from the server than it gains in harshness.
What to watch out for
True forbids, False permits. Read it as “allow base building” and you lock out your entire server by accident.
The ban only applies to new construction. Whatever is already built remains – and keeps decaying under the normal rules. Truly clearing a map needs a wipe on top.
