Coroutine chaining in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start a coroutine named MyCoroutine.

Unity

StartCoroutine([1]);

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

A"MyCoroutine"

BMyCoroutine()

CMyCoroutine

DStartMyCoroutine()

💡 Hint

Common Mistakes

Passing the coroutine method name as a string without parentheses.

Passing the method name without parentheses.

In Unity, to start a coroutine, you call StartCoroutine with the coroutine method call including parentheses, like MyCoroutine().

2fill in blank

medium

Complete the code to wait for 2 seconds inside a coroutine.

Unity

yield return [1];

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

Anew WaitForSeconds(2)

BWaitForSeconds(2f)

Cnew WaitForSeconds(2f)

DWaitForSeconds(2)

💡 Hint

Common Mistakes

Forgetting the new keyword.

Not using parentheses around the time value.

To wait inside a coroutine, you yield return a new instance of WaitForSeconds with the time in seconds.

3fill in blank

hard

Fix the error in the coroutine chaining code to wait for SecondCoroutine to finish before continuing.

Unity

yield return [1](SecondCoroutine());

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

AInvoke

BWaitForSeconds

CStartCoroutine

DStart

💡 Hint

Common Mistakes

Using WaitForSeconds instead of StartCoroutine.

Calling Invoke which does not return IEnumerator.

To wait for another coroutine to finish, you yield return StartCoroutine with the coroutine call.

4fill in blank

hard

Fill both blanks to chain two coroutines so that FirstCoroutine waits for SecondCoroutine before continuing.

Unity

IEnumerator FirstCoroutine() {
    yield return [1](SecondCoroutine());
    Debug.Log([2]);
}

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

AStartCoroutine

B"Second coroutine finished"

C"Coroutine done"

DDebug.Log

💡 Hint

Common Mistakes

Not using StartCoroutine to wait.

Logging the wrong message.

You use StartCoroutine to wait for SecondCoroutine. Then you log a message indicating the second coroutine finished.

5fill in blank

hard

Fill all three blanks to create a coroutine that chains three coroutines and logs messages after each finishes.

Unity

IEnumerator ChainCoroutines() {
    yield return [1](CoroutineOne());
    Debug.Log([2]);
    yield return [3](CoroutineTwo());
    Debug.Log("All coroutines done");
}

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

AStartCoroutine

B"Coroutine One finished"

D"Coroutine Two finished"

Attempts:

💡 Hint

Common Mistakes

Not using StartCoroutine for both coroutines.

Mixing up the log messages.

Use StartCoroutine to wait for each coroutine. Log messages after each finishes to show progress.
