Struct SceneLoader 

pub struct SceneLoader;

Static helper methods for loading and unloading scenes.

Implementations

impl SceneLoader

pub fn load_scene( manager: &mut SceneManager, name: &str, data: SceneData, ) -> Result<SceneId, GoudError>

Loads a scene from a SceneData into the manager.

Creates a new scene with the given name, registers built-in serializable components, and deserializes the scene data into the world.

Errors

Returns an error if:

• A scene with the same name already exists
• Deserialization of scene data fails

pub fn unload_scene( manager: &mut SceneManager, name: &str, ) -> Result<(), GoudError>

Unloads a scene by name.

Looks up the scene by name and destroys it. Dropping the [World] cleans up all entities and components.

Errors

Returns an error if:

• No scene with the given name exists
• The scene is the default scene (which cannot be destroyed)

pub fn load_scene_from_json( manager: &mut SceneManager, name: &str, json: &str, ) -> Result<SceneId, GoudError>

Loads a scene from a JSON string.

Parses the JSON into SceneData, then delegates to load_scene.

Errors

Returns an error if:

• The JSON is invalid or does not match the expected schema
• Scene creation or deserialization fails

pub fn save_scene_to_json( manager: &SceneManager, id: SceneId, ) -> Result<String, GoudError>

Saves a scene to a JSON string.

Serializes all entities and components in the scene’s world, then converts to a pretty-printed JSON string.

Errors

Returns an error if:

• The scene ID does not exist
• Serialization fails
