Trait primitives::prelude::SceneManager

pub trait SceneManager {
    fn scene(&self) -> Box<dyn EngineScene>;

The SceneManager should be implemented by objects intended to manage the EngineScene state machine.

Only a single scene is active at any given update. Which scene is configured by this manager.

Required Methods

fn scene(&self) -> Box<dyn EngineScene>

The currently active scene. Use as a runtime property and not as an initialization property.

fn set_scene(&self, kind: SceneKind)

Sets the current scene to a new scene.

Arguments

• kind - The new scene.

fn back(&self)

Sets the current scene to the scene returned by Factory::get_back_scene_type(). The new scene should be representative of retreat. @see Factory::get_back_scene_type

fn next(&self)

Sets the current scene to the scene returned by Factory::get_next_Scene_type(). The new scene should be representative of progress. @see Factory::get_next_scene_type

fn restart(&self)

Restarts the current scene. Equivalent of disposing current scene and then setScene to current scene again.
