Struct Sprite 

#[repr(C, align(4))]
pub struct Sprite {
    pub tag: u32,
    pub color_cmd: u32,
    pub xy: u32,
    pub uv_clut: u32,
    pub wh: u32,
}

Textured sprite (variable size). 5 words (tag + 4 data).

Fields

tag: u32

OT linkage.

color_cmd: u32

0x64000000 | color header (blend color applied over texture).

xy: u32

Top-left xy.

uv_clut: u32

uv | clut (U/V in low half, CLUT handle in high half).

wh: u32

Size wh.

Implementations

impl Sprite

pub const WORDS: u8 = 4

Data-word count.

pub const fn new( x: i16, y: i16, w: u16, h: u16, uv: (u8, u8), clut: u16, r: u8, g: u8, b: u8, ) -> Self

Build a textured sprite. clut is the CLUT register handle (y << 6 | x >> 4); uv is the 8-bit texcoord within the texture page.

pub const fn with_material( x: i16, y: i16, w: u16, h: u16, uv: (u8, u8), material: TextureMaterial, ) -> Self

Build a textured sprite using a TextureMaterial.

Sprite packets do not carry a tpage word. The material’s CLUT, tint, raw-texture bit, and semi-transparent command bit are encoded in the packet; the caller must set the matching draw mode before OT submission if the sprite samples a non-current tpage.

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.

impl GpuPacket for Sprite

const WORDS: u8 = Sprite::WORDS

Payload words after the tag.

impl Hash for Sprite

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given [Hasher].

impl PartialEq for Sprite

fn eq(&self, other: &Sprite) -> 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.
