Question 10

What risk comes from excessive Gizmos in a scene?

A. They clutter the Scene view, making it hard to
B. They change prefab connections
C. They increase runtime GPU load
D. They delete object data

Answer

A. They clutter the Scene view, making it hard to

Explanation

Overusing Gizmos can overwhelm the Scene view with visual noise, reducing clarity and making it difficult for developers and designers to interpret important information.

Question 11

How can Gizmos be customized for clarity?

A. By changing color, size, and shape of visual aids
B. By rewriting Unity’s physics system
C. By modifying inspector serialization
D. By disabling Scene view

Answer

A. By changing color, size, and shape of visual aids

Explanation

Customizing Gizmos through color, scale, and form helps differentiate visual elements and improves readability, especially when multiple debugging visuals are present.

Question 12

What is the purpose of SnapTo Grid code in Unity editor scripting?

A. To speed up animation playback
B. To compress assets for mobile
C. To align objects consistently within a grid
D. To replace Unity’s lighting settings

Answer

C. To align objects consistently within a grid

Explanation

SnapTo Grid ensures objects are placed at uniform intervals, maintaining clean alignment and consistency, which is particularly important for level design and modular environments.

Question 13
