Unity Game Development Quiz

What is the main purpose of using parent-child GameObject relationships in Unity?

• To optimize frame rate

• To simplify scripting

• To create hierarchical transformations

• To reduce file size

In Unity, what does the Transform component primarily manage?

• Input handling

• Visual appearance

• Position, rotation, and scale

• Physics calculations

What does the Transform.Find() method do?

• Finds the next GameObject in the hierarchy

• Finds a GameObject in the scene

• Finds a child Transform by name

• Finds a script component

What is the recommended structure for a robotic arm in this assignment?

• Separate scripts for each arm

• Nested GameObjects under a root 'Arm'

• A single flat list of GameObjects

• Prefabs without parenting

What does `foreach (Transform child in transform)` allow you to do?

• Update all scripts in a scene

• Iterate through all children of a GameObject

• Delete components

• Import assets

How can rotation be animated in a wave-like pattern in Unity?

• By using Time.deltaTime only

• By applying a fixed rotation every frame

• By using Mathf.Sin(Time.time)

• By using rigidbody forces

What C# method is used to create a GameObject at runtime?

• Create()

• Instantiate()

• Spawn()

• Generate()

What is required for a newly instantiated segment to follow its parent’s transform?

• Add it to the scene view

• Attach it to a rigidbody

• Set its parent using Transform.SetParent()

• Enable physics simulation

Why use visual feedback like colored cubes on each segment?

• To increase memory usage

• To identify GameObjects by layer

• To visually track individual segment rotations

• To reduce script complexity

In Unity, what does setting a GameObject's parent affect?

• Its material

• Its script execution order

• Its transform relative to the parent

• Its audio settings
