Struct GlobalTransform 

pub struct GlobalTransform(pub AffineTransform);

A component that stores the final, calculated, world-space transformation of an entity.

This component’s value is the result of combining the entity’s local Transform with the GlobalTransform of its Parent, recursively up to the root of the scene.

It is intended to be read-only for most systems (like rendering and physics). It should only be written to by the dedicated transform propagation system. This acts as a cache to avoid re-calculating the full transform hierarchy every time it’s needed.

Implementations

impl GlobalTransform

pub fn new(matrix: Mat4) -> GlobalTransform

Creates a new GlobalTransform from a Mat4.

pub fn identity() -> GlobalTransform

Creates a new identity GlobalTransform.

pub fn to_matrix(&self) -> Mat4

Returns the inner Mat4 representation.

pub fn at_position(position: Vec3) -> GlobalTransform

Creates a GlobalTransform representing a translation.

Trait Implementations

impl Clone for GlobalTransform

fn clone(&self) -> GlobalTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for GlobalTransform

fn make_column() -> Box<dyn AnyVec>

where Self: Sized,

Creates this component’s empty storage column. Default: an AoS Vec<Self>.

fn push_into_column(self, column: &mut (dyn AnyVec + 'static))

where Self: Sized,

Appends self as a new row into its column.

fn copy_row_between( src: &(dyn AnyVec + 'static), src_row: usize, dst: &mut (dyn AnyVec + 'static), )

where Self: Sized,

Clones row src_row from src into dst (used when an entity migrates between pages on a structural change). Both columns are this component’s column type.

fn clone_from_column(column: &(dyn AnyVec + 'static), row: usize) -> Self

where Self: Sized,

Reads row row of column as an owned value — the uniform by-value access path that works for both AoS (clone the &T) and field-SoA (gather the fields) layouts. Used by World::clone_component, the Soa<T> query, and the serialization recipe.

fn set_in_column(self, column: &mut (dyn AnyVec + 'static), row: usize)

where Self: Sized,

Overwrites row row of column with self — the uniform by-value write path for both layouts (AoS assigns the slot; field-SoA scatters into the lanes). Used by World::set_component.

impl Debug for GlobalTransform

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

Formats the value using the given formatter.

impl Default for GlobalTransform

fn default() -> GlobalTransform

Returns the identity GlobalTransform.

impl PartialEq for GlobalTransform

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