Struct BillboardBehavior 

pub struct BillboardBehavior { /* private fields */ }

BBSC — Billboard behavior (v0, 48 bytes)

Turns one bone to face the camera. The only source of billboarding there is: BoneFlag::Billboard1/2 are set on no bone in the whole corpus.

StarCraft II applies these at draw time, per view, from sub_10290A890 — CBBSolver::Solve is a stub — and writes the bone’s local rotation, so the subtree follows.

Implementations

impl BillboardBehavior

pub fn new() -> Self

Panics

Panics if the native allocation fails.

pub fn dependents(&self) -> &[u16]

Dependent bone indices (U16_). Empty in every shipped record; the engine never reads them Zero-copy view of the underlying std::vector.

pub fn dependents_mut(&mut self) -> &mut [u16]

Zero-copy mutable view. Resize first — the borrow forbids it after.

pub fn set_dependents(&mut self, values: &[u16])

pub fn resize_dependents(&mut self, count: usize)

pub fn bone_index(&self) -> u16

Index into BONE array

pub fn set_bone_index(&mut self, value: u16)

pub fn billboard_type(&self) -> u8

Which axes may turn — see BillboardType

pub fn set_billboard_type(&mut self, value: u8)

pub fn camera_look_at(&self) -> u8

Non-zero: aim from this bone at the eye. Zero: aim along the camera’s view direction instead, so every such bone shares one orientation

pub fn set_camera_look_at(&mut self, value: u8)

pub fn up(&self) -> Quaternion

MISNAMED: not a direction. A rotation applied before the billboard basis, and only by the axis-locked types 0/1/2

pub fn set_up(&mut self, value: Quaternion)

pub fn forward(&self) -> Quaternion

MISNAMED likewise: the same kind of pre-rotation, taken only by type 6, and only on a bone whose parent is another bone. Types 3/4/5 take neither

pub fn set_forward(&mut self, value: Quaternion)

Trait Implementations

impl Debug for BillboardBehavior

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

Formats the value using the given formatter.

impl Default for BillboardBehavior

fn default() -> Self

Returns the “default value” for a type.

impl Drop for BillboardBehavior

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
