Struct bevy_hierarchy::ChildBuilder
source · pub struct ChildBuilder<'a> { /* private fields */ }
Expand description
Struct for building children entities and adding them to a parent entity.
§Example
This example creates three entities, a parent and two children.
commands.spawn(MyBundle {}).with_children(|child_builder| {
child_builder.spawn(MyChildBundle {});
child_builder.spawn(MyChildBundle {});
});
