// Create a new RuntimeScene RuntimeScene* newScene = new RuntimeScene(); // Load a scene file newScene->load_scene("level1.tscn"); // Get all nodes of a certain type in the scene Array nodes = newScene->get_nodes_by_type("Enemy"); // Update the scene each frame while (true) { newScene->update(); }In the first example, a new RuntimeScene object is created. In the second example, a scene file is loaded into the scene. In the third example, all nodes of the "Enemy" type are retrieved from the scene. In the fourth example, the scene is updated each frame in a loop. Overall, RuntimeScene is a useful class for managing game levels and scenarios in the Godot game engine.
