Methods from Deref<Target = GlobalTransform>

pub const IDENTITY: GlobalTransform = _

pub fn compute_matrix(&self) -> Mat4

Returns the 3d affine transformation matrix as a Mat4.

pub fn affine(&self) -> Affine3A

Returns the 3d affine transformation matrix as an Affine3A.

pub fn compute_transform(&self) -> Transform

Returns the transformation as a Transform.

The transform is expected to be non-degenerate and without shearing, or the output will be invalid.

pub fn reparented_to(&self, parent: &GlobalTransform) -> Transform

Returns the Transform self would have if it was a child of an entity with the parent GlobalTransform.

This is useful if you want to “reparent” an Entity. Say you have an entity e1 that you want to turn into a child of e2, but you want e1 to keep the same global transform, even after re-parenting. You would use:

#[derive(Component)]
struct ToReparent {
    new_parent: Entity,
}
fn reparent_system(
    mut commands: Commands,
    mut targets: Query<(&mut Transform, Entity, &GlobalTransform, &ToReparent)>,
    transforms: Query<&GlobalTransform>,
) {
    for (mut transform, entity, initial, to_reparent) in targets.iter_mut() {
        if let Ok(parent_transform) = transforms.get(to_reparent.new_parent) {
            *transform = initial.reparented_to(parent_transform);
            commands.entity(entity)
                .remove::<ToReparent>()
                .set_parent(to_reparent.new_parent);
        }
    }
}

The transform is expected to be non-degenerate and without shearing, or the output will be invalid.

pub fn to_scale_rotation_translation(&self) -> (Vec3, Quat, Vec3)

Extracts scale, rotation and translation from self.

The transform is expected to be non-degenerate and without shearing, or the output will be invalid.

pub fn right(&self) -> Dir3

pub fn translation(&self) -> Vec3

Get the translation as a Vec3.

pub fn translation_vec3a(&self) -> Vec3A

Get the translation as a Vec3A.

pub fn radius_vec3a(&self, extents: Vec3A) -> f32

Get an upper bound of the radius from the given extents.

pub fn transform_point(&self, point: Vec3) -> Vec3

Transforms the given point, applying shear, scale, rotation and translation.

This moves point into the local space of this GlobalTransform.

pub fn mul_transform(&self, transform: Transform) -> GlobalTransform

Multiplies self with transform component by component, returning the resulting GlobalTransform
