Struct SpriteLighting 

pub struct SpriteLighting<'a> {
    pub kv6col: u32,
    pub lightmode: u32,
    pub lights: &'a [LightSrc],
}

Sprite lighting + colour state — the subset of voxlap’s vx5 global that updatereflects reads. Built once per frame from Engine state and passed to draw_sprite.

All fields mirror voxlap names:

• kv6col ↔ vx5.kv6col
• lightmode ↔ vx5.lightmode
• lights ↔ vx5.lightsrc[0..vx5.numlights]

The vx5.fogcol/ofogdist fog plumbing is deferred — sprite fog stays off for now, matching the oracle path (vx5.fogcol < 0 ⇒ ofogdist == -1 in voxlap C, no fog).

Fields

kv6col: u32

Material colour. R==G==B triggers the cheaper nolighta path in update_reflects; arbitrary RGB takes the per-channel nolightb path; lightmode≥2 ignores the R==G==B fast path and always does per-channel modulation.

lightmode: u32

0 / 1 → directional surface tint (lightmode<2 paths). 2 → per-light shadow-side modulation against lights.

lights: &'a [LightSrc]

Active point lights — voxlap’s vx5.lightsrc[..vx5.numlights]. Empty for lightmode<2; populated for lightmode≥2.

Implementations

impl<'a> SpriteLighting<'a>

pub fn from_engine(engine: &'a Engine) -> Self

Snapshot the lighting + colour subset of an Engine. Use this once per frame in the host so the sprite render reflects engine setters made between frames.

impl SpriteLighting<'static>

pub fn default_oracle() -> Self

Default oracle config — grey kv6col, lightmode 0, no lights. Used by roxlap-oracle so the four sprite golden hashes stay byte-stable: this is the exact state voxlap C’s oracle has when it calls drawsprite.
