💡 Hint

Common Mistakes

Using 1 instead of 0 for the first scene index.

Trying to load scene by name without quotes.

Using the active scene instead of the build index.

The first scene in Unity's build settings has index 0. Using LoadScene(0) loads that scene.

Complete the code to add a scene named "Level2" to the build settings scenes list.

Unity

💡 Hint

Common Mistakes

Using the wrong scene name that does not exist.

Forgetting the folder path "Assets/Scenes/".

Not including the .unity extension in the path.

To add a scene to build settings, specify its path. Here, "Level2" is the scene name.

3fill in blank

hard

Fix the error in the code to correctly get the total number of scenes in build settings.

Unity

int sceneCount = [1].Length;

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

ASceneManager.GetAllScenes()

BEditorBuildSettings.scenes

CBuildSettings.scenes

DSceneManager.sceneCountInBuildSettings

💡 Hint

Common Mistakes

Using EditorBuildSettings.scenes which is editor-only.

Trying to call a method that does not exist.

Using incorrect property names.

SceneManager.sceneCountInBuildSettings returns the total number of scenes in the build settings.

4fill in blank

hard

Fill both blanks to check if the current active scene is the last in build settings.

Unity

bool isLastScene = SceneManager.GetActiveScene().buildIndex [1] SceneManager.sceneCountInBuildSettings [2] 1;

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

C+

D!=

💡 Hint

Common Mistakes

Using + instead of - when adjusting scene count.

Using != instead of == for comparison.

Mixing up the order of operands.

The active scene's build index equals the total scenes minus 1 if it is the last scene.

5fill in blank

hard

Fill all three blanks to create a dictionary mapping scene names to their build indexes for all scenes in build settings.

Unity

var sceneDict = new Dictionary<string, int>() {
  { [1], [2] }
};
for (int i = 1; i < SceneManager.sceneCountInBuildSettings; i++) {
  sceneDict.Add(SceneUtility.GetScenePathByBuildIndex(i).Split('/').Last().Replace(".unity", ""), i);
}

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

ASceneUtility.GetScenePathByBuildIndex(0).Split('/').Last().Replace(".unity", "")

B0

CSceneUtility.GetBuildIndexByScenePath("Assets/Scenes/Main.unity")

D"Main"

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong index or scene name for the first dictionary entry.

Not removing the .unity extension from scene names.

Using SceneUtility.GetBuildIndexByScenePath incorrectly.

This code initializes the dictionary with the first scene's name and index 0. It uses SceneUtility.GetScenePathByBuildIndex(0) to get the path, extracts the name, and sets index 0. The string "Main" is the scene name for the first entry.
