Summary - Scene management

Reinforce scene management usage with a summary task.

Summary: Scene Management System

In this module, you mastered all phases of professional scene management. Build Settings orders scene assets; SceneManager.LoadScene handles standard switches, while Additive mode layers multi-scene setups.

// Scene Management Workflow Summary:
// 1. Build Settings: Scenes In Build (Index 0, 1, 2)
// 2. SceneManager.LoadScene("Level1", LoadSceneMode.Single/Additive)
// 3. DontDestroyOnLoad(GameManager)
// 4. SceneManager.LoadSceneAsync -> Loading Screen Progress

DontDestroyOnLoad keeps manager data alive across levels, and LoadSceneAsync powers smooth, freeze-free loading screens.

Exercise Print complete scene management profile

Define index (0), scene ("MainMenu"), and mode ("Async"). Print Index: 0 | Scene: MainMenu | Mode: Async to the console.

Show example solution

using System;

class Program
{
    static void Main()
    {
        int index = 0;
        string scene = "MainMenu";
        string mode = "Async";
        Console.WriteLine("Index: " + index + " | Scene: " + scene + " | Mode: " + mode);
    }
}

Test yourself

Which statement regarding scene transitions and object persistence in the Scene management system is correct?
- When Additive mode is used, the old scene is forcibly deleted and DontDestroyOnLoad fails.
- LoadSceneAsync is exclusively a mixer function used to load audio assets.
- Scenes must reside in Build Settings; DontDestroyOnLoad preserves objects, and LoadSceneAsync loads in the background.
- Adding a scene to Build Settings is not necessary for loading; the file name alone suffices.
Show answer

Scenes must reside in Build Settings; DontDestroyOnLoad preserves objects, and LoadSceneAsync loads in the background. — Scenes must be registered in the build list; persistent entities rely on DontDestroyOnLoad and background streaming uses LoadSceneAsync.

Load scene in single mode

SceneManager.LoadScene(0, LoadSceneMode.____);

Show answer

SceneManager.LoadScene(0, LoadSceneMode.Single);
