Struct Sprite 

pub struct Sprite {
    pub kv6: Kv6,
    pub p: [f32; 3],
    pub s: [f32; 3],
    pub h: [f32; 3],
    pub f: [f32; 3],
    pub flags: u32,
}

A KV6 voxel sprite positioned in world space.

Mirror of voxlap’s vx5sprite for the kv6 case (flags & SPRITE_FLAG_KFA == 0; see SPRITE_FLAG_KFA). Owns its Kv6 by value. p / s / h / f are voxlap’s per-axis world-space basis: s is the kv6.xsiz direction, h the ysiz direction, f the zsiz direction. For an axis-aligned sprite, s = [1,0,0], h = [0,1,0], f = [0,0,1].

Fields

kv6: Kv6

Voxel data + bounding-box pivots. Loaded from a .kv6 file via crate::kv6::parse or built procedurally.

p: [f32; 3]

World-space position of the sprite’s pivot (xpiv, ypiv, zpiv inside the kv6 maps to this point).

s: [f32; 3]

World-space basis vector for the kv6’s local +x. Length scales the sprite along that axis (typically 1.0 for unit-scale).

h: [f32; 3]

World-space basis vector for the kv6’s local +y.

f: [f32; 3]

World-space basis vector for the kv6’s local +z.

flags: u32

Voxlap-style flags bitfield. See SPRITE_FLAG_NO_SHADING, SPRITE_FLAG_KFA, SPRITE_FLAG_INVISIBLE, SPRITE_FLAG_NO_Z.

Implementations

impl Sprite

pub fn axis_aligned(kv6: Kv6, pos: [f32; 3]) -> Self

Convenience constructor for an axis-aligned sprite at world position pos. Basis is identity, flags = 0 (kv6 + normal shading + visible + z-tested).

Examples

use roxlap_formats::kv6::Kv6;
use roxlap_formats::sprite::Sprite;

// ... after `let kv6 = kv6::parse(&bytes)?;` or similar:
let sprite = Sprite::axis_aligned(kv6, [1024.0, 1024.0, 100.0]);
assert_eq!(sprite.flags, 0);
assert_eq!(sprite.s, [1.0, 0.0, 0.0]);

Trait Implementations

impl Clone for Sprite

fn clone(&self) -> Sprite

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sprite

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
