Scene loading and unloading in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to load a scene named "GameScene" using Unity's SceneManager.

Unity

SceneManager.[1]("GameScene");

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

AUnloadSceneAsync

BLoadScene

CLoadSceneAsyncAdditive

💡 Hint

Common Mistakes

Using UnloadSceneAsync instead of LoadScene.

Confusing synchronous and asynchronous loading methods.

The LoadScene method loads a scene synchronously by its name.

2fill in blank

medium

Complete the code to unload a scene named "MenuScene" asynchronously.

Unity

SceneManager.[1]("MenuScene");

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

ALoadScene

BGetSceneByName

CUnloadSceneAsync

DLoadSceneAsync

💡 Hint

Common Mistakes

Using LoadScene instead of unloading.

Using synchronous unload methods which don't exist.

The UnloadSceneAsync method unloads a scene asynchronously by its name.

3fill in blank

hard

Fix the error in the code to load a scene additively named "Level2".

Unity

SceneManager.LoadScene("Level2", [1].Additive);

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

ALoadSceneMode

BSceneLoadMode

CSceneManagerMode

DLoadMode

💡 Hint

Common Mistakes

Using incorrect enum names like SceneLoadMode.

Forgetting to specify additive mode.

The LoadSceneMode enum specifies how to load the scene, and Additive loads it without unloading current scenes.

4fill in blank

hard

Fill both blanks to load a scene named "BonusLevel" asynchronously and additively.

Unity

SceneManager.[1]("BonusLevel", [2].Additive);

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

ALoadSceneAsync

BLoadScene

CLoadSceneMode

DUnloadSceneAsync

Attempts:

💡 Hint

Common Mistakes

Using synchronous LoadScene instead of LoadSceneAsync.

Using wrong enum like UnloadSceneAsync.

LoadSceneAsync loads the scene asynchronously, and LoadSceneMode.Additive loads it additively without unloading other scenes.

5fill in blank

hard

Fill all three blanks to unload a scene named "OldScene" asynchronously and check if unloading is done.

Unity

AsyncOperation asyncOp = SceneManager.[1]("OldScene");
if (asyncOp.[2])
{
    Debug.Log("Scene unloaded successfully.");
}
else
{
    Debug.Log("Scene is still unloading.");
}
asyncOp.[3] += () => Debug.Log("Unload completed event triggered.");

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

DLoadSceneAsync

💡 Hint

Common Mistakes

Using LoadSceneAsync instead of UnloadSceneAsync.

Checking wrong property instead of isDone.

Not subscribing to the completed event properly.

UnloadSceneAsync starts unloading the scene asynchronously. isDone checks if the operation finished. completed is an event triggered when unloading finishes.
