hbstyle

HULLBREAKER's visor language: the palette and the six primitives every panel of the helmet HUD is built from, so the instruments read as one panel rather than as a pile of boxes.

local S = require("ui.hbstyle")

The palette says what a colour means

glass is nearly opaque on purpose. The frame behind the HUD swings from black vacuum to a lit planet filling half the visor, and a readout legible over one and washed out over the other is not a readout.

Primitives

• pane(extra) — the glass a cluster sits on: a lit top edge and a step in lightness, which is what reads as raised on a near-black frame.
• bar(pct, color, opts) — the HUD's one repeated instrument. opts.ghost draws a dimmer fill behind the live one (the quota bar uses it for cargo carried but not yet banked).
• gauge(caption, value, pct, color, opts) — caption and value on a line, bar under it.
• pips(count, litCount, opts) — discrete danger as discrete lights.
• cap / num / txt — the three type sizes, all monospace.
• riseIn(delay, dy) — the one-shot entrance the cards come in on. Only a screen registered once may carry it: a node re-registered every frame restarts its animation, so anything on the live instrument layer blinks from a computed opacity instead.
• clock(seconds) / tonnes(t) — the two formats the run reads by.
