Keeping a zone's numbers together instead of scattered.
Every object has a permanent number. When you make something, MegaMOO gives it
the lowest free number it can find. That is fine for a lamp or a chair, but it
means that a zone built over several sessions ends up scattered — the tavern is
#204, its cellar is #251, and the room you added last
week is #198, because other things were being made in between.
Reserving a block of numbers keeps a zone together. If the harbour district is
#500–#599, then a number in the 500s tells you at a
glance which part of the world you are looking at, and a builder working on the
forest at #600 cannot accidentally take one of your numbers.
This is worth doing for anything you think of as a unit — a district, a dungeon, a questline — and not worth doing for scenery.
The starter world reserves several low blocks for future core objects.
Run @fon/list to see them before choosing where your zone
goes; picking a high, round number is the simplest way to stay clear.
Two commands, and the naming is the only confusing part. Think of a number as free when the engine is allowed to hand it out automatically:
| Command | Does |
|---|---|
@fon/set 500 to 599 | Sets the block you are working with. Do this first. |
@foff | Free off — reserves every unused number in the block. The engine stops handing them out. |
@fon | Free on — releases the block's unused numbers back for normal use. |
@fon/list | Shows every reserved unused number, grouped into ranges. |
@fon/clear | Forgets the block you set. Does not release anything. |
Both need gm3. Reserving only affects numbers that are still
unused — objects that already exist are untouched.
Owners with gm5 can also reserve a block directly, without setting
it as their working range:
> @reserve #500 to #599
> @reserve/free #500 to #599
> @reserve/listYou are about to build a harbour district and want it to live in the 500s.
1. Claim the block.
> @fon/set 500 to 520
Set free_obj range to #500-#520 (21 objects).
> @foff
Reserved 21 unused object numbers in #500-#520.From now on nothing lands there by accident. Anything you or another builder creates gets a number from outside the block:
> @make $item = probe
Created #207:a probe, added to inventory. # skipped the 500s2. Build, then move each piece into the block. New objects still arrive with whatever number was free, so put them where you want them:
> @renumber #207 to #500
Renumbered #207 to #500:a probe.
Work through the zone this way and the harbour ends up at #500,
#501, #502 and so on, in the order you built it.
@renumber needs gm5.
3. Give back what you did not use. When the zone is finished, release the leftovers so they are not held out of circulation forever:
> @fon
Unreserved 21 unused object numbers in #500-#520.The numbers you actually used are objects now, so they are unaffected. Only the empty ones go back into the pool.
@fon/list at any point shows what is currently held,
grouped into ranges — the quickest way to see whether your block is
reserved and how much of it you have left.
