A place the player can be sent, as a row of a listing.
devtools/src/travel.ts:47Members
addressreadonly
Text address — the same string generation, saves and logs key off.
bodyKindreadonly
The body's own class, or null on a system row.
Structured rather than left inside detail, because two readers now branch
on it and both were reduced to parsing a sentence: the catalog draws a glyph
per class — a comet is not a circle — and its filter chips select by it.
detail is a line of prose for a human and must stay free to be rewritten.
childrenreadonly
How many bodies go round this one. Planets for a star, moons for a planet.
colorreadonly
The star's own color, linear sRGB, or null on a body row.
A measurement rather than decoration: docs/design/art.md puts a star's
color on the list of things the game may not invent, because it follows
from the effective temperature. A K dwarf is orange and does not get to be
a nicer orange. Carried here rather than looked up from the class letter,
so the glyph in the catalog and the disk in the sky are the same number.
depthreadonly
0 for a system, 1 for a planet, 2 for a moon: the tree depth to indent by.
detailreadonly
Kind, size and orbit, already formatted for display.
distancereadonly
Distance from wherever the listing was taken.
From the sweep that produced the row, which is not always the last one:
sameTargets keeps a listing whose every text is unchanged, so a
subscriber holding rows through a hover holds this number from whenever
the text last moved. It is wrong by less than distanceText's own
resolution and by no more; anything that needs the meter wants
UV.distance against a fresh pose rather than a row of a listing.
distanceTextreadonly
kindreadonly
landablereadonly
Whether land will work: solid ground and big enough to be a place.
loadedreadonly
Whether the system is generated and its frames installed.
namereadonly
parentreadonly
The row this one hangs off — a body's primary, a system's own address.
What makes the flat listing a tree the panel can fold. Sol is 129 bodies and a list that cannot be collapsed is a list nobody scrolls twice.
provenancereadonly
Whether this is a place somebody has actually seen, or one this generator expects to be there.
The epistemic fact, and it is the one the interface promises to state
(PRODUCT.md). It is not loaded: loaded is a streaming fact about this
session, and a real star is real whether or not its frames are installed.
The projection used to drop this, so Alpha Centauri and an invented star
four light years the other way rendered identically.
radiusreadonly
Equatorial radius, meters. A star's own on a system row.
semiMajorAxisreadonly
Semi-major axis about its primary, meters. 0 on a system row.
spectralTypereadonly
Spectral type on a system row, null on a body.
systemreadonly
The system this row belongs to, so a listing can be grouped or filtered.
