Use this skill when loading, unloading, or organizing scenes, implementing additive scene architectures, or building scene transition flows in Unity.

DontDestroyOnLoad

Prevents a GameObject from being destroyed when a new scene loads (in Single mode).

public class AudioManager : MonoBehaviour
{
    private static AudioManager _instance;

    private void Awake()
    {
        // Singleton guard -- prevents duplicates when returning to a scene
        if (_instance != null)
        {
            Destroy(gameObject);
            return;
        }
        _instance = this;
        DontDestroyOnLoad(gameObject);
    }
}

Pitfalls:

Objects in DontDestroyOnLoad cannot reference scene objects (they get destroyed)
If the scene containing the singleton is loaded again, a duplicate spawns -- the guard above is mandatory
DontDestroyOnLoad objects live in a special hidden scene (visible in Hierarchy under "DontDestroyOnLoad")
With additive scene loading + bootstrapper pattern, you often do not need DontDestroyOnLoad at all -- the boot scene itself persists

Game Type	Recommended Pattern
Simple (1-5 scenes)	`LoadSceneAsync` with Single mode + loading screen
Medium (menu + levels)	Bootstrapper + additive loading
Large (open world)	Addressables + streaming + additive loading
Prototype / game jam	Synchronous loading is fine
