Functions
constexpr HudColor	weaponTypeAccent (int weaponId)
	Map a weapon-type id (matching WeaponType integer order in ecs/components/WeaponState.hpp: 0=Rifle, 1=Rocket, 2=RailGun, 3=EnergyGun, 4-6=grenades) to its accent color.
constexpr HudColor	withAlpha (HudColor c, float alpha)
	Apply alpha to a palette color (for fade-out).
void	drawCornerBrackets (HudContext &ctx, float x, float y, float w, float h, float armLen=10.f, float thickness=1.f, float outset=0.f, HudColor color=k_amber)
	Draw four mil-spec L-shaped corner brackets around a rect.
void	drawPanel (HudContext &ctx, float x, float y, float w, float h, HudColor fill=k_bgPanel, HudColor border=k_line, float thickness=1.f)
	Draw a Voidfall panel: solid fill + 1 px outline.
void	drawTrailBar (HudContext &ctx, float x, float y, float w, float h, float fill01, float trail01, HudColor fillColor, HudColor trailColor=HudColor{0.95f, 0.95f, 0.95f, 0.45f}, HudColor bgColor=k_bgInset, HudColor borderColor=k_lineDim)
	Draw a horizontal stat bar with a damage-trail ghost (solid fill).
constexpr HudColor	lerpColor (HudColor a, HudColor b, float t)
	Lerp between two HudColors — used to compute the visible gradient endpoint when the bar is partially filled (so the fill always represents the same slice of the underlying full-bar gradient instead of stretching to the right end).
void	drawGradientTrailBar (HudContext &ctx, float x, float y, float w, float h, float fill01, float trail01, HudColor fillLeft, HudColor fillRight, HudColor trailColor=HudColor{0.95f, 0.95f, 0.95f, 0.45f}, HudColor bgColor=k_bgInset, HudColor borderColor=k_lineDim)
	Draw a horizontal stat bar whose live fill is a left→right gradient (e.g.
void	drawKeyTab (HudContext &ctx, const char *key, float x, float y, float fontSize, float padX=3.f, float padY=1.f, HudColor bgColor=HudColor{0.f, 0.f, 0.f, 0.45f}, HudColor borderColor=k_lineBright, HudColor textColor=k_textDim)

Variables
constexpr HudColor	k_bgVoid {0.08f, 0.075f, 0.07f, 0.96f}
	Deep panel background — opaque so HUD chrome doesn't pick up sky tint.
constexpr HudColor	k_bgPanel {0.10f, 0.095f, 0.085f, 0.92f}

Function Documentation

drawCornerBrackets()

void voidfall::drawCornerBrackets ( HudContext & ctx, float x, float y, float w, float h, float armLen = 10.f, float thickness = 1.f, float outset = 0.f, HudColor color = k_amber )

inline

Draw four mil-spec L-shaped corner brackets around a rect.

Brackets sit slightly outside the rect (offset by outset px) and extend armLen px along each edge. Style: 1 px hairlines, amber by default.

drawGradientTrailBar()

void voidfall::drawGradientTrailBar ( HudContext & ctx, float x, float y, float w, float h, float fill01, float trail01, HudColor fillLeft, HudColor fillRight, HudColor trailColor = HudColor{0.95f, 0.95f, 0.95f, 0.45f}, HudColor bgColor = k_bgInset, HudColor borderColor = k_lineDim )

inline

Draw a horizontal stat bar whose live fill is a left→right gradient (e.g.

health: deep red → orange-red, shield: dim cyan → cyan).

fillLeft and fillRight describe the colors for a full (100%) bar. At partial fills the right endpoint of the visible portion is interpolated to fill01 along that gradient — which keeps the warm/bright tail at 100% and the cool/dim head as the bar drains, matching the prototype's linear-gradient(90deg, red, orange-red) CSS behavior.

drawKeyTab()

void voidfall::drawKeyTab ( HudContext & ctx, const char * key, float x, float y, float fontSize, float padX = 3.f, float padY = 1.f, HudColor bgColor = HudColor{0.f, 0.f, 0.f, 0.45f}, HudColor borderColor = k_lineBright, HudColor textColor = k_textDim )

inline

Draw a bordered "key tab" pill with a single character inside.

Used by equipment slots and pickup hints. The text is centered inside the box; sizing is based on the cap-height of the SDF font for visual balance.

drawPanel()

void voidfall::drawPanel ( HudContext & ctx, float x, float y, float w, float h, HudColor fill = k_bgPanel, HudColor border = k_line, float thickness = 1.f )

inline

Draw a Voidfall panel: solid fill + 1 px outline.

drawTrailBar()

void voidfall::drawTrailBar ( HudContext & ctx, float x, float y, float w, float h, float fill01, float trail01, HudColor fillColor, HudColor trailColor = HudColor{0.95f, 0.95f, 0.95f, 0.45f}, HudColor bgColor = k_bgInset, HudColor borderColor = k_lineDim )

inline

Draw a horizontal stat bar with a damage-trail ghost (solid fill).

Background fill, then a translucent ghost-trail rectangle (where the bar was before the latest damage tick), then the live fill on top. This is the "white ghost draining behind the live red" effect from the design.

lerpColor()

HudColor voidfall::lerpColor ( HudColor a, HudColor b, float t )

constexpr

Lerp between two HudColors — used to compute the visible gradient endpoint when the bar is partially filled (so the fill always represents the same slice of the underlying full-bar gradient instead of stretching to the right end).

weaponTypeAccent()

HudColor voidfall::weaponTypeAccent ( int weaponId )

constexpr

Map a weapon-type id (matching WeaponType integer order in ecs/components/WeaponState.hpp: 0=Rifle, 1=Rocket, 2=RailGun, 3=EnergyGun, 4-6=grenades) to its accent color.

Here is the caller graph for this function:

withAlpha()

HudColor voidfall::withAlpha ( HudColor c, float alpha )

constexpr

Apply alpha to a palette color (for fade-out).

Variable Documentation

k_amber

HudColor voidfall::k_amber {1.00f, 0.71f, 0.18f, 1.0f}

constexpr

Primary amber — oklch(0.80 0.165 75).

k_amberDeep

HudColor voidfall::k_amberDeep {0.50f, 0.35f, 0.10f, 1.0f}

constexpr

Deep amber — oklch(0.45 0.10 70).

k_amberDim

HudColor voidfall::k_amberDim {0.78f, 0.55f, 0.14f, 1.0f}

constexpr

Dimmer amber — oklch(0.65 0.13 75).

k_amberGlow

HudColor voidfall::k_amberGlow {1.00f, 0.71f, 0.18f, 0.18f}

constexpr

Amber glow tint — oklch(0.80 0.165 75 / 0.15).

k_bgInset

HudColor voidfall::k_lineDim {0.32f, 0.30f, 0.28f, 0.7f}

constexpr

Dim hairline — oklch(0.32 0.015 60 / 0.6).

k_pickupBg

HudColor voidfall::k_pickupBg {0.13f, 0.12f, 0.11f, 0.82f}

HudColor voidfall::k_redDim {0.65f, 0.20f, 0.15f, 1.0f}

constexpr

HudColor voidfall::k_text {0.92f, 0.90f, 0.87f, 1.0f}

constexpr

Standard text — bumped slightly toward white for body chrome.

k_textBright

HudColor voidfall::k_textBright {1.00f, 0.99f, 0.97f, 1.0f}

constexpr

Brightest text — kept near-white for hero readouts.

k_textDim

HudColor voidfall::k_textDim {0.78f, 0.76f, 0.73f, 1.0f}
