public static AsyncOperation LoadSceneAsync (string sceneName, SceneManagement.LoadSceneMode mode= LoadSceneMode.Single);
public static AsyncOperation LoadSceneAsync (int sceneBuildIndex, SceneManagement.LoadSceneMode mode= LoadSceneMode.Single);


sceneName 読み込むシーンの名前かパス
sceneBuildIndex 開くシーンの Build Settings での インデックス
mode LoadSceneMode.Single を選択すると読み込みの前に現在のシーンすべてが解放されます。


AsyncOperation 操作が終了したかを判別するには、AsyncOperation を使用します。



The given scene name can either be the full scene path, the path shown in the Build Settings window or just the scene name. If only the scene name is given this will load the first scene in the list that matches. If you have multiple scenes with same name but different paths, you should use the full scene path. Examples of supported formats: "Assets/Scenes/Scene1.unity" "Scenes/Scene1" "Scene1"

public class Example : MonoBehaviour { void Update() { //Press the space key to start coroutine if (Input.GetKey(KeyCode.Space)) { //Use a coroutine to load the Scene in the background StartCoroutine(LoadYourAsyncScene()); } }

IEnumerator LoadYourAsyncScene() { // The Application loads the Scene in the background at the same time as the current Scene. //This is particularly good for creating loading screens. You could also load the scene by build //number. AsyncOperation asyncLoad = SceneManager.LoadSceneAsync("Scene2");

//Wait until the last operation fully loads to return anything while (!asyncLoad.isDone) { yield return null; } } }
