Enum SpriteOrientation 

pub enum SpriteOrientation {
    CameraFacing,
    VelocityStretched,
    AxisLocked,
}

How a sprite batch’s billboards are oriented in world space.

Picked per batch; all instances in one SpriteItem share the same mode.

Variants

CameraFacing

Every quad turns to face the camera. This is the standard particle and marker behaviour and the historical default.

VelocityStretched

Each quad’s long axis follows the projected per-instance velocity vector, with length scaled by the velocity magnitude. Use for sparks, muzzle flashes, bullets, and rain streaks. Requires the matching entry in SpriteItem::velocities for each instance.

AxisLocked

Each quad’s long axis is locked to a single world-space direction shared by every instance. Use for grass cards, plume columns, and anything tethered to world up. The axis comes from SpriteItem::axis.

Trait Implementations

impl Clone for SpriteOrientation

fn clone(&self) -> SpriteOrientation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SpriteOrientation

impl Debug for SpriteOrientation

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

Formats the value using the given formatter.

impl Default for SpriteOrientation

fn default() -> SpriteOrientation

Returns the “default value” for a type.

impl Eq for SpriteOrientation

impl PartialEq for SpriteOrientation

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