Addressables.LoadSceneAsync missing allowSceneActivation

so it’s not possible to load the scene in inactive state then control its activation

time to update the docu, don’t you think…

I’m not seeing what’s wrong with the docs here? allowSceneActivation is for the SceneManager API. Your solution is exactly what that doc mentions for the Addressables API.

Adding

loadAsync.Result.ActivateAsync();

did not help for me. Could you elaborate on this a bit?

In 2024 I still cannot load a scene in background and not activate it with Addressables…activateOnLoad=false simply does not work

I manage to load and activate it like this:

        private string sceneToLoad = "scene";

        private void LoadScene()
        {
            Addressables.LoadSceneAsync(this.sceneToLoad, LoadSceneMode.Additive, false).Completed += this.OnSceneLoaded;
        }

        private void OnSceneLoaded(AsyncOperationHandle<SceneInstance> obj)
        {
            if (obj.Status != AsyncOperationStatus.Succeeded)
            {
                return;
            }
          
            obj.Result.ActivateAsync().completed += this.OnSceneActivated;
        }
      
        private void OnSceneActivated(AsyncOperation obj)
        {
            Scene sceneToActivate = SceneManager.GetSceneByName(this.sceneToLoad);
            SceneManager.SetActiveScene(sceneToActivate);
        }
