save bevy scene

[cherish-ltt]

i spawn a TextBundle with TextStyle:font

.with_children(|parent| {
 parent.spawn(TextBundle::from_section(
    "Button",
    TextStyle {
        font: world.load_asset("fonts/zh.ttf"),
        font_size: 100.0,
        color: Color::srgb(1.0, 1.0, 1.0),
},
));
});

then, i save the world to file

// Scenes can be serialized like this:
    let type_registry = world.resource::<AppTypeRegistry>();
    let type_registry = type_registry.read();
    let serialized_scene = scene.serialize(&type_registry).unwrap();`
err:
`called `Result::unwrap()` on an `Err` value: Message("Type 'std::sync::Arc<bevy_asset::handle::StrongHandle>' did not register ReflectSerialize")

i see the Handle<A> is with #[derive(Component, Reflect)] and #[reflect(Default, Component, Debug, Hash, PartialEq)],
but StrongHandle is not has reflect trait,what should i do

now,i use Handle.clone_weak() to save scene
it is show:

resources: {
    "silk_road_handle_lynn::scene::game_scene::ResourceA": (
      score: 1,
    ),
    "silk_road_handle_lynn::assets::image::ButtonBackgroundImage": (
      common_buttom_image: Weak(Index(
        index: (
          generation: 0,
          index: 3,
        ),
      )),
    ),
  },
......
texture: Weak(Index(
            index: (
              generation: 0,
              index: 3,
            ),
          )),
......

when i load this scene, it texture is Weak, how to change Handle to Strong

Unfortunately, Bevy does not serialize asset handles. Even if it did, you would need an asset server to deserialize them. I believe this is being addressed by the scene rework described here.

In your case you could filter out the components containing handles with the DynamicSceneBuilder, make a custom component that serializes to an asset path, and then generate the handles with some startup system from your component. You can also forego Bevy scenes and write a custom asset loader that handles a custom serializable asset.
