Enum SpriteLightMode 

pub enum SpriteLightMode {
    FaceNormal,
    WorldUp,
    AmbientOnly,
    FullBright,
}

Per-instance billboard lighting mode (BB.2b), decoded from the sprite flags (bits 6/7). Controls the surface normal / direct-light handling at the sprite shade site so a camera-facing billboard needn’t suffer the camera-dependent N·L of its (camera-tracking) face normal.

Variants

FaceNormal

The DDA hit-face normal (default; today’s DL.7 look).

WorldUp

A fixed world-up normal (stable directional shading).

AmbientOnly

Ambient only — no sun / point-light direct term (flat cutout).

FullBright

Full-bright / emissive — the voxel colour at full intensity, ignoring lighting (glows: fire, spell auras). Encoded as both flag bits set.

Implementations

impl SpriteLightMode

pub fn from_flags(flags: u32) -> Self

Trait Implementations

impl Clone for SpriteLightMode

fn clone(&self) -> SpriteLightMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SpriteLightMode

impl Eq for SpriteLightMode

impl PartialEq for SpriteLightMode

fn eq(&self, other: &SpriteLightMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
