Two gaps between the first quests, both of the same kind: a step the chain
assumed rather than asked for.
#142 - "collect 5 ore" was followed straight by "build the mothership",
which costs twenty. The first thing the chain ever asked for was four times
what it had just taught, with nothing in between saying so. A stockpile
quest sits between them now.
#141 - the crafter quest's brief said "spend ore on the Shipyards doctrine,
then put a ship crafter down", which is two unrelated things off one line:
open a menu the player has never opened, and place a structure. Researching
Shipyards is its own quest now, and it is the one that says where the
research tree lives. Every later quest that needs a doctrine still only
mentions it in passing - once is enough.
That needed a goal kind for researching a doctrine, which the model did not
have.
Both are pinned as properties rather than as positions in a list. The chain
must ask for at least as much ore as the first structure it wants costs; and
the first structure that is gated behind a doctrine must have that doctrine
as a quest of its own. Only the first - demanding one per building would
double the chain for no teaching.
One thing that fell out of writing those: the pile is exactly the starting
fleet's hold. An interceptor carries 20 and the mothership costs 20, and
before the mothership exists there is nowhere to bank anything, so the hold
is the only store there is. It fits with no slack at all, so there is now an
assertion saying so - a pile larger than the hold would be a quest that
cannot be finished, and nothing else would have caught it.
The standing tracker #132 put on the HUD sat in the right-hand column, on
top of the dev wave button - and there is no free strip of that edge to move
it to, because everything down it is already something. So the objective
stops living on the HUD: a quest button beside the map's, and a panel when
you press it.
The panel shows the current objective, its progress, and the road behind it.
Deliberately NOT what comes next - the chain is meant to open the game up a
step at a time (#133), and a list of everything still to come is that
discovery given away on the first press.
It owns its own button, the way WorldMap owns the map button rather than
being wired through BuildController, and it hides that button during the
prologue for the same reason and in the same two places (at _ready as well
as in _process, since #128 means a dialog stops the tree before the first
_process frame ever comes).
Both scenes carry it. On a planet surface there is no map button to sit
beside, so it goes under the planet's name.
The test now checks the button is beside the map's and clear of the wave
button by rectangle rather than by eye, which is the bug the ticket reported.
Sixteen quests that walk a new game through the things it contains: ore,
the mothership, exploration, a yard and a second hull, planetfall and
conquest, extractors, gas, freight, power, the lab, a new vessel type, an
outpost, and a survey.
The chain turns on the second quest. The fleet builds the mothership to
call the World Ship and hears nothing - and the array is not at fault. The
breach put them further out than that signal will carry, so every quest
after it is a search that has to be flown rather than transmitted.
Three pieces:
Quests.gd the chain, as data and nothing else. Two rules it obeys:
nothing may ask for something unreachable - research points
come only from conquering a planet, so every doctrine that
costs them sits after the conquest quest - and a quest names
one goal, with the research it implies said in the brief
rather than split into an errand of its own.
GameState how far along the chain the player is, and the answer to each
goal kind. Progress latches for free: the chain is walked one
quest at a time, so collecting five ore and spending it cannot
un-complete the quest that asked for five - by then nothing is
asking. It lives here so a quest finished on a planet surface
is still finished after take-off.
the HUD QuestTracker, the standing objective, in the wave alert's
idiom; QuestDirector, which reads the lines out.
Lines are QUEUED by GameState and drained by the director rather than
emitted at a banner, because quests advance in the autoload, which runs on
a planet surface too - where a line emitted straight at a banner would be
lost. Both scenes now carry a banner, a tracker and a director, so a quest
finished underground is announced underground.
The chain is armed by reset_new_game(), the same gate the prologue uses -
the only door into a real game - so instantiating a scene is not by itself
a reason to start briefing somebody.
