2. In order to load the scene in runtime. We need to add the scenes in the build settings.
3. Next, create an empty new scene and named it bootstrap.unity. This is the scene contains the Scene Flow Manager and use to control the loading of other scenes.
4. In the scene, create a “Scene Flow Manager”. Right click on the hierarchy and select menu Digicrafts > Scene Flow Manager. Along with Scene Flow manager, a sceneflow.asset file will be created in the same directory. This is the file for storing the scene flow graph.
5. Select the Scene Flow Manager from the hierarchy window and open the Scene Flow Editor by the edit button in inspector.
6. Use the toolbar button ”+Add Base Scene” and add the scenes, Game Main and Game Play, from the list. Or, you can drag and drop the scenes from project windows to Graph Editor windows.
