💡 Hint

Common Mistakes

Complete the code to check if a scene named "Level1" is loaded.

Unity

bool isLoaded = UnityEngine.SceneManagement.SceneManager.GetSceneByName("Level1").[1];

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using isActive which means if the scene is active, not loaded.

Using isOpen or isReady which are not valid properties.

The property isLoaded tells if a scene is currently loaded in Unity.

💡 Hint

Common Mistakes

Using UnloadScene which does not exist.

Using LoadScene instead of unloading.

To unload a scene in Unity, use UnloadSceneAsync because unloading is asynchronous.

4fill in blank

hard

Fill both blanks to create a dictionary of scene names and their build indexes for scenes loaded.

Unity

var scenes = new Dictionary<string, int> { { [1], [2] } };

Drag options to blanks, or click blank then click option'

AUnityEngine.SceneManagement.SceneManager.GetActiveScene().name

BUnityEngine.SceneManagement.SceneManager.GetActiveScene().buildIndex

CUnityEngine.SceneManagement.SceneManager.GetSceneAt(0).name

DUnityEngine.SceneManagement.SceneManager.GetSceneAt(0).buildIndex

Attempts:

3 left

💡 Hint

Common Mistakes

Using GetSceneAt(0) which may not be the active scene.

Mixing name and buildIndex from different scene calls.

Use GetActiveScene().name for the scene name and GetActiveScene().buildIndex for its build index.

5fill in blank

hard

Fill all three blanks to create a dictionary using a loop that maps scene names to their build indexes for all loaded scenes.

Unity

var sceneDict = new Dictionary<string, int>(); for(int [3] = 0; [3] < UnityEngine.SceneManagement.SceneManager.sceneCount; [3]++) { sceneDict[[1]] = [2]; }

Drag options to blanks, or click blank then click option'

AUnityEngine.SceneManagement.SceneManager.GetSceneAt(i).name

BUnityEngine.SceneManagement.SceneManager.GetSceneAt(i).buildIndex

Ci

Dindex

💡 Hint

Common Mistakes

Using a variable other than i for the loop without changing all references.

Mixing scene name and buildIndex from different scene calls.

Use GetSceneAt(i).name and GetSceneAt(i).buildIndex inside a loop with variable i to build the dictionary.
