Screens

Puts every authored screen of First Light: Luteway on the glass and drives them. It is mounted once, on mount_screens, and needs nothing else on that entity.

What it draws

The HUD is two vertical rails down the left edge with the readout above them and the pause pip opposite. Nothing spans the frame: the game films at 1080x1440, and the engine's own touch overlay lives in a band on the right, so a bar across the top would fit neither.

What decides which card is up

LW.state.phase, which the climb slice's Game.component owns.

How to play is an overlay over whichever card opened it, not a phase, so it reads the same from the title card and from the pause card.

When the player takes a line, this component emits uiRequest(action) — "start", "pause", "resume", "restart", "title" — and waits. If nothing has moved the phase within a moment it moves the phase itself, so the game is reachable from its own title card whatever else is loaded. The moment Game answers uiRequest, that fallback stops firing on its own.

Controls

uimenu is activated the instant a card goes up and released the instant the last one comes down; it stands down climb, player and uipause while it is live. uipause stays live through play and carries the control that opens the pause card.

• Focus moves on navigate (arrow keys / d-pad) and navigateStick (left stick), wraps at both ends, and lands on something the instant a card opens. The focused line carries a crest-yellow ring, a lit edge marker and a diamond, and shifts a few points to the right.
• Choose on confirm (Enter, Space, south), leave on back (Escape, Backspace, right mouse, east), and an end card also answers restart (R, north).
• A pointer or a thumb takes a line by touching it, which also moves the ring there, so a player who mixes a mouse and a pad never loses their place.
• Each card carries the legend for the family in the player's hands, read from /runtime/input/device and published as LW.state.device. The how-to card redraws its whole control table for that family.

Public fields

• menuMap: assetRef(inputMap) — the menu scheme. Default uimenu.
• pauseMap: assetRef(inputMap) — the pause control. Default uipause.

Methods

• :repaint() — force the next tick to rebuild every screen. The screens are repainted only when their own inputs change, and a hot reload of lwui is not one of those inputs, so this is how an edit to the design system reaches the glass without restarting anything.
• :focus() — { card, id, device }: the card that is up, the line the ring is on, and the family being drawn for.
• :setDevice(name?) — pin the family the legends and the how-to card are drawn for; nil hands it back to the device counters.

Lifecycle

• awake() — paints the first frame.
• update(dt) / editorUpdate(dt) — one tick either way: reads the device, resolves the card the phase asks for, activates or releases the menu scheme, and repaints only the screens whose inputs changed.
• onDestroy() — releases both schemes and unregisters every screen it put up.
