Struct bevy_transform::components::GlobalTransform

source ·
pub struct GlobalTransform(/* private fields */);
Expand description

Describe the position of an entity relative to the reference frame.

§Transform and GlobalTransform

Transform is the position of an entity relative to its parent position, or the reference frame if it doesn’t have a Parent.

GlobalTransform is the position of an entity relative to the reference frame.

GlobalTransform is updated from Transform by systems in the system set TransformPropagate.

This system runs during PostUpdate. If you update the Transform of an entity in this schedule or after, you will notice a 1 frame lag before the GlobalTransform is updated.

§Examples

Implementations§

source§

impl GlobalTransform

source

pub const IDENTITY: Self = _

An identity GlobalTransform that maps all points in space to themselves.

source

pub fn compute_matrix(&self) -> Mat4

Returns the 3d affine transformation matrix as a Mat4.

source

pub fn affine(&self) -> Affine3A

Returns the 3d affine transformation matrix as an Affine3A.

source

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.

source

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.

source

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.

This moves point into the local space of this GlobalTransform.
