Trait that defines adding, changing and children and parents of an entity directly through the World
.
Required Methods§
sourcefn with_children(
&mut self,
spawn_children: impl FnOnce(&mut WorldChildBuilder<'_>)
) -> &mut Self
fn with_children( &mut self, spawn_children: impl FnOnce(&mut WorldChildBuilder<'_>) ) -> &mut Self
Takes a clousre which builds children for this entity using WorldChildBuilder
.
sourcefn push_children(&mut self, children: &[Entity]) -> &mut Self
fn push_children(&mut self, children: &[Entity]) -> &mut Self
Pushes children to the back of the builder’s children. For any entities that are already a child of this one, this method does nothing.
If the children were previously children of another parent, that parent’s Children
component
will have those children removed from its list. Removing all children from a parent causes its
Children
component to be removed from the entity.
sourcefn insert_children(&mut self, index: usize, children: &[Entity]) -> &mut Self
fn insert_children(&mut self, index: usize, children: &[Entity]) -> &mut Self
sourcefn remove_children(&mut self, children: &[Entity]) -> &mut Self
fn remove_children(&mut self, children: &[Entity]) -> &mut Self
Removes the given children
Removing all children from a parent causes its Children
component to be removed from the entity.
