How to Load a scene from addressable on the preloading scene without changing scenes?,How do I preload an addressable scene without changing the scene?

Question

I want to preload the scene from the addressables and keep it without changing scenes. Addressables.LoadSceneAsync("sceneName"); does load but it changes the scenes as soon as it finishes. I don't want that. I just want to load it on the preloading scene, then use that to load the scene when I press the button for it.

Please help, it is very urgent. Best Regards.,I want to preload a scene that has been marked as addressable without it changing scene. Maybe be saving on some type of variable. And than referencing to that scene whenever I want to get to the scene.

I want to achieve something like this in the preloader. But I don't want to change the scene right away. Addressables.LoadSceneAsync("sceneName");

 public string NextScene = "MainMenu";
 public AssetReference Level;
 
 long downloadSize;
 AsyncOperationHandle asyncHandle;
 
 void Awake()
 {
     if (Level.RuntimeKeyIsValid() Addressables.GetDownloadSizeAsync(Level.RuntimeKey).Completed += GetDownloadSize_Completed;
 }
 
 void GetDownloadSize_Completed(AsyncOperationHandle<long> obj)
 {
     if (obj.IsValid())
     {
         downloadSize = obj.Result;
         asyncHandle = Addressables.DownloadDependanciesAsync(Level.RuntimeKey);
         asyncHandle.Completed += Preloader_Completed;
     }
 }
 
 void Preloader_Completed(AsyncOperationHandle obj)
 {
     if (obj.IsValid())
     {
         if (obj.Result != null) SceneManager.LoadScene(NextScene, LoadSceneMode.Single);
     }
 }
 
 void Update()
 {
     // Do your progress bar updates here... etc
 }

Note: Download size can be 0 if the content is already cached so don't rely on the size. The size can be useful in determining how far along you are, for example you can display in a text box:

 if (asyncHandle.IsValid())
     status.text = $"{asyncHandle.PercentComplete * downloadSize} / {downloadSize}";

Though, I've found it not to be entirely accurate. You might want to remap the range or something, in my case I found that 0.18 to 0.48 percent is the true range. I'm not entirely certain why.

 var loadAsync = Addressables.LoadSceneAsync("sceneName", activateOnLoad=true);

then when you're ready to activate:

 loadAsync.Result.Activate();
