10/// Plugin that adds the transform propagation system to PostUpdate.
11///
12/// This plugin registers [`TransformPropagationSystem`] in the
13/// [`CoreStage::PostUpdate`] stage, ensuring that global transforms are
14/// recomputed after all user systems have run.
15///
16/// # Example
17///
18/// ```rust,ignore
19/// use goud_engine::ecs::app::App;
20/// use goud_engine::ecs::app::TransformPropagationPlugin;
21///
22/// let mut app = App::new();
23/// app.add_plugin(TransformPropagationPlugin);
24/// ```
25#[derive(Debug, Default, Clone)]
26pub struct TransformPropagationPlugin;
27
28impl Plugin for TransformPropagationPlugin {
29    fn build(&self, app: &mut App) {
30        app.add_system(CoreStage::PostUpdate, TransformPropagationSystem::new());
31    }

38/// A plugin group that adds all default engine plugins.
39///
40/// Currently includes:
41/// - [`TransformPropagationPlugin`]: Automatic transform hierarchy propagation
42///
43/// # Example
44///
45/// ```rust,ignore
46/// use goud_engine::ecs::app::App;
47/// use goud_engine::ecs::DefaultPlugins;
48///
49/// let mut app = App::new_with_defaults();
50/// // Or manually:
51/// let mut app = App::new();
52/// app.add_plugin_group(DefaultPlugins);
53/// ```
