Both halves of the ticket, in the shape vessels have used since gas bombers
and laser ships: a definition carries an ore figure and, when it wants more
than ore, a dictionary that IS the price. `building_costs()` and
`skill_costs()` answer it the way `product_costs()` already did, so there is
one question with one answer whatever is being bought, and every payment
path now goes through `spend_resources` rather than `spend`.
Seven of ten structures and thirteen of seventeen doctrines now want gas,
energy or dark matter alongside their rocks, and the totals climb with tree
depth - structures 16/31/58/62/96 by depth, doctrines 15/30/73/96/143/258/530.
The constraint that shaped the table is REACHABILITY, and it is the reason
some prices stayed ore-only. Energy exists only where a gas burner stands,
and a gas burner needs Power Systems - so nothing at or before that depth
may be priced in energy, or it is a wall with no way through. Dark matter is
rarer still and appears once, on the deepest node in the game. The extractor
stays rocks-only despite its depth allowing gas, because the quest chain
reaches it before it has sent the player for any.
test_progressive_costs checks those as properties rather than transcribing
the numbers, so rebalancing a price costs nothing while breaking the shape
fails: nothing unreachable at its own depth, prices rising with depth, the
ore field agreeing with the dictionary (repairs quote the field alone, since
a repair drone carries ore and nothing else), and the quest chain never
asking for a structure it has not funded.
Two things cleaned up on the way:
- The per-building cost constants in GameState are gone. Nothing but tests
used them, and they were a second copy of a number the definitions already
hold - exactly what would drift once a price gained a resource.
- research_for_building() returns a display NAME, and the id-keyed half of
the tree wants an id. That mix-up is silent - skill_depth() of a name finds
no node and answers 0, so a deep structure reads as an ungated one, which
is how the first draft of the test let an unreachable price through.
research_node_for_building() is the id, and the name is expressed from it.
PriceTag no longer rebuilds its labels when re-told the same price; it
refreshes the held figures instead. The craft menu re-states prices every
frame and the build menu now does too, so that was a dozen Labels being torn
down and rebuilt sixty times a second.
Landed together: a board of standing orders nothing acts on is a notepad,
and a planner with nowhere to read the plan from has nothing to do.
The targets are GLOBAL, not per building. There is one plan for the whole
game, and a second planning centre is another place to read and edit it
rather than a competing one - per-building targets would let two centres
hold contradictory orders and tell the crafters to satisfy both.
The census is the harder half. Every vessel is counted exactly once wherever
it happens to be: flying in the fleet, parked in the hangar, stationed at an
outpost, or in the air between any two of those. Miss the in-flight ones and
the planner queues a replacement for a vessel that is merely en route. The
fleet is the one place GameState cannot see, so Fleet pushes its composition
on every change, alongside the cargo capacity and distorder count that
already went that way.
Three rules keep the planner from fighting the player. It tops up and never
rewrites, so an order placed by hand stays exactly where it is. Everything
counts, including what is already queued, or it re-queues the same shortfall
every tick and buries the player in hulls. And nothing happens without a
planning centre - though the plan is remembered when one is destroyed, so
rebuilding picks up where it left off.
Vessels on order are counted separately from the census on purpose: they do
not exist yet, so the readout can say "4 of 6, 2 building" rather than
claiming six. The per-row note says where the vessels actually are, because
a plan can look unmet while everything it asked for is sitting at an
outpost.
The build menu goes to three columns past eight entries. #54 already
tightened its rows to 223px to fit a fourth, explicitly to avoid a
scrollable menu, and a ninth structure needs a fifth row that will not fit
at any spacing a button, a label and a cost can share. Three columns take
nine into three rows - fewer than it uses today, not more.
