💡 Hint

Common Mistakes

Using a generic name like 'audioClip' which usually refers to the sound file, not the player.

Using names that imply sound effects instead of background music.

The variable backgroundMusic is a clear and descriptive name for the AudioSource that will play the background music.

💡 Hint

Common Mistakes

Using AudioClip instead of AudioSource causes errors because AudioClip is not a component.

Using AudioListener which is for hearing sounds, not playing them.

GetComponent<AudioSource>() gets the AudioSource component attached to the same GameObject.

Fix the error in the code to play the background music only once at the start.

Unity

void Start() {
    backgroundMusic.[1]();
}

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

BPlayOneShot

CPlay

DPause

Attempts:

💡 Hint

Common Mistakes

Using PlayOneShot causes the clip to play overlapping if called multiple times.

Using Stop or Pause does not start the music.

Play() starts playing the AudioSource clip once from the beginning.

4fill in blank

hard

Fill both blanks to create a dictionary that maps scene names to background music clips.

Unity

Dictionary<string, AudioClip> musicByScene = new Dictionary<string, AudioClip>() {
    {"MainMenu", [1],
    {"Level1", [2]
};

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

CmenuMusic

💡 Hint

Common Mistakes

Mixing up clip names or using unrelated variable names.

Using variable names that do not represent AudioClip objects.

The dictionary keys are scene names and values are AudioClip variables named accordingly.

5fill in blank

hard

Fill all three blanks to set the background music clip and play it if the scene has music.

Unity

if (musicByScene.ContainsKey([1])) {
    backgroundMusic.clip = musicByScene[[2]];
    backgroundMusic.[3]();
}

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

AcurrentScene

CPlay

DStop

💡 Hint

Common Mistakes

Using different variables for the scene name in the dictionary lookup.

Using Stop instead of Play to start the music.

We check if the dictionary has the current scene name, then assign the clip and play it.
