Practice - 5 Tasks

1fill in blank

easy

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

AAddComponent

BGetComponent

CFindComponent

DGetChild

💡 Hint

Common Mistakes

Using AddComponent instead of GetComponent, which adds a new component instead of fetching.

Using FindComponent which does not exist.

The GetComponent method retrieves a component of the specified type attached to the GameObject.

Complete the code to get the AudioSource component from the current GameObject.

Unity

AudioSource audio = [1].GetComponent<AudioSource>();

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

💡 Hint

Common Mistakes

Using 'this' which refers to the script instance, not the GameObject.

Using 'transform' which is a component, not the GameObject itself.

gameObject refers to the current GameObject, from which we get the AudioSource component.

3fill in blank

hard

Fix the error in the code to correctly get the Collider component.

Unity

Collider col = gameObject.[1]<Collider>();

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

AGetComponent<Collider>

BGetComponent<Collider>()

CGetComponent()

DGetComponent

💡 Hint

Common Mistakes

Putting the generic type inside the blank, causing syntax errors.

Including parentheses inside the blank.

The method GetComponent must be called with the type inside angle brackets and parentheses after it. The blank is for the method name only, so GetComponent is correct here.

4fill in blank

hard

Fill both blanks to get the SpriteRenderer component from the child GameObject.

Unity

SpriteRenderer sr = transform.[1](0).gameObject.[2]<SpriteRenderer>();

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

AGetChild

BGetComponent

CFindChild

DGetParent

Attempts:

3 left

💡 Hint

Common Mistakes

Using FindChild which is deprecated or does not exist.

Using GetParent which gets the parent, not the child.

GetChild(0) gets the first child Transform, then GetComponent<SpriteRenderer>() gets the SpriteRenderer component from that child GameObject.

5fill in blank

hard

Fill all three blanks to get the Light component from the parent GameObject's first child.

Unity

Light lightComp = transform.[1]().[2](0).gameObject.[3]<Light>();

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

AGetParent

BGetChild

CGetComponent

DFind

Attempts:

3 left

💡 Hint

Common Mistakes

Using Find which searches the whole scene and is not a Transform method.

Mixing up GetParent and GetChild order.

GetParent() gets the parent Transform, GetChild(0) gets its first child, and GetComponent<Light>() gets the Light component from that child's GameObject.
