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.

# Headless gameplay test: run with

# A new game opens with a SINGLE vessel and three slots, and the fleet grows
|
|
# from there through the doctrine branch of the skill tree.
|
|
#
|
|
# BASE_FLEET_SIZE used to be both "how many slots exist" and "how many ships
|
|
# you start with", which forced a new game to open with a full fleet - there
|
|
# was nowhere to put a vessel until a doctrine was researched, so the first
|
|
# ship crafter had nothing to do. The two are now separate constants, and
|
|
# this test pins the distinction.
|
|
#
|
|
# Covers:
|
|
# A. a new game starts with one vessel and three slots
|
|
# B. the fleet really spawns one ship, and can be grown into its slots
|
|
# C. every doctrine raises the ceiling by its own stated bonus
|
|
# D. the doctrine branch is a chain, in increasing cost order
|
|
# E. the tree cannot promise a slot the formation has no room for - the
|
|
# invariant that made extra doctrines silently worthless
