Instantiating objects at runtime in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to instantiate a prefab at the origin with no rotation.

Unity

Instantiate(prefab, [1], Quaternion.identity);

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

Atransform.position

BVector3.zero

Cnew Vector3(1, 1, 1)

DQuaternion.Euler(0, 0, 0)

Attempts:

3 left

💡 Hint

Common Mistakes

Using a rotation value instead of a position.

Using transform.position which may not be the origin.

Using Vector3.zero places the object at the origin (0,0,0).

2fill in blank

medium

Complete the code to instantiate a prefab at the player's position.

Unity

Instantiate(prefab, [1], Quaternion.identity);

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

Aplayer.transform.position

BVector3.one

Cnew Vector3(0, 0, 0)

Dtransform.rotation

Attempts:

3 left

💡 Hint

Common Mistakes

Using Vector3.one which is (1,1,1) not the player's position.

Using transform.rotation instead of position.

Using player.transform.position places the new object exactly where the player is.

3fill in blank

hard

Fix the error in the code to instantiate a prefab with the same rotation as the spawner object.

Unity

Instantiate(prefab, transform.position, [1]);

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

AQuaternion.identity

Btransform.position

CVector3.zero

Dtransform.rotation

Attempts:

3 left

💡 Hint

Common Mistakes

Using position instead of rotation.

Using Quaternion.identity which resets rotation.

transform.rotation uses the spawner's rotation for the new object.

4fill in blank

hard

Fill both blanks to instantiate a prefab at a random position within a range and with no rotation.

Unity

Vector3 randomPos = new Vector3(Random.Range(-10, 10), 0, [1]);
Instantiate(prefab, randomPos, [2]);

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

ARandom.Range(-5, 5)

BRandom.Range(-10, 10)

CQuaternion.identity

Dtransform.rotation

Attempts:

3 left

💡 Hint

Common Mistakes

Using transform.rotation which applies spawner rotation.

Using a fixed number instead of Random.Range for position.

The z position uses Random.Range(-10, 10) for randomness, and Quaternion.identity means no rotation.

5fill in blank

hard

Fill all three blanks to instantiate a prefab, set its parent to the spawner, and name it "SpawnedObject".

Unity

GameObject obj = Instantiate([1], transform.position, [2]);
obj.transform.parent = [3];
obj.name = "SpawnedObject";

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

Btransform.rotation

Ctransform

Dplayer

Attempts:

3 left

💡 Hint

Common Mistakes

Not setting the parent correctly.

Using player instead of transform for parent.

Using Quaternion.identity instead of spawner rotation.

Instantiate the prefab at the spawner's position with its rotation, then set the parent to transform (the spawner).
