What it does

theme

The look of every screen in RED DOT RISING, in one place: the palette, the type scale, the motion helpers, and metrics().

metrics() reads ui.screenSize() afresh on every call and hands back the numbers a tree sizes itself from — a scale k taken from the SHORT axis of the live screen, a pad, a gap, a card width, and fs(n) / px(n) to put a design number through k. Nothing in the game is a pixel position chosen for one frame; that is what lets the same trees lay out at 810x1080, at 1920x1080 and on a phone held either way.

The palette is derived from Core.C so the HUD and the room agree on what red is. M.entrance(t, order, dy) and M.enter(style, ...) drive a card's entrance from Luau a frame at a time, because a one-shot CSS animation plays once per element ID and does not replay on a re-push of the same tree — and a card's tree is rebuilt every time the lit row moves. M.pulse stays declarative, because an infinite animation is the case that repeats.

local T = require("game.ui.theme")
local m = T.metrics()
{ type = "label", props = { text = "DAWN" }, style = T.kicker(m, T.CYAN, 11) }

Interface

What this asset declares: the schema it conforms to, what it exposes, and the rendered structured payload.

conforms to

zero/source-extract/v2

game.ui.theme — the look of every screen in RED DOT RISING. Three things live here and nothing else: the palette (derived from Core.C so the HUD and the room agree on what red is), the type scale, and `metrics()`, which reads ui.screenSize() every call and hands back the numbers a tree lays itself out from. Nothing in this file is a pixel position. `metrics()` gives a scale `k` taken from the SHORT axis of the live screen, and every size a tree writes is `t.fs(n)` or `m.pad` or a percentage of the parent. That is what makes one tree read at 810x1080, at 1920x1080 and on a phone held either way.

hex(c: { number }, a: number?) → string

Core.C keeps its colours as linear-ish {r,g,b} triples for materials and lights; CSS wants hex. One conversion, here, so there is exactly one definition of the game's red.

entrance(t: number, order: number?, dy: number?) →

The style an entrance is at, `t` seconds in. Merge it into a node's own style: it fades the node up and settles it down to rest, and past the end of the move it adds nothing at all. This is driven from Luau, one frame at a time, rather than declared as a CSS `animation`, because a card's tree is rebuilt every time the lit row moves and a one-shot animation's play state belongs to the element ID, not to the rebuild: re-pushing an identical tree does not replay it. Declared, a card would animate the first time its rows ever existed and never again. Driven, it plays once every time a card OPENS, which is what the player should see. The pulses below stay declared, because an infinite animation is the case that repeats.
