Mixed Deck — All Unity Topics Flashcards

What is a trailing stop order?

Answer: A stop-loss that automatically adjusts upward as the price rises, locking in profits while protecting against reversals

Trailing stops move with the price in a favorable direction but stay fixed when the price moves against you, automatically locking in gains.

The Unity Editor is in this mode, which is indicated by the red play controls:

Answer: Animation Record

When the Unity Editor's play controls (play, pause, stop) turn red, it indicates that the editor is in Animation Record mode. In this mode, any changes made to a GameObject's properties will automatically create keyframes in the Animation window, allowing you to easily record animations by simply manipulating objects in the Scene view.

In Unity's Animation system, what is an Animator Controller used for?

Answer: Managing state machines and transitions between animations

An Animator Controller manages the state machine that controls which animation clips play and when transitions between them occur.

What is the Unity Event System and why is it useful in scripts?

Answer: A publisher-subscriber pattern using UnityEvent that decouples event senders from receivers

UnityEvent implements a publisher-subscriber pattern, allowing scripts to broadcast events without direct references to the listeners.

In Unity animation, what is the purpose of an Animation Layer?

Answer: To stack multiple independent animation state machines that can blend or override each other

Animation Layers allow you to run separate state machines simultaneously, such as playing an upper-body reload animation while lower-body locomotion continues.

What does the Physics.Raycast() function return in Unity?

Answer: A boolean indicating whether the ray hit a collider, plus hit information

Physics.Raycast() returns true if the ray intersects a collider and fills a RaycastHit struct with details about the hit point, normal, and object.

Why is attention to detail important in professional work?

Answer: Small errors can have significant consequences, and thoroughness builds trust and ensures quality outcomes

In most professional fields, small oversights can lead to significant problems. Consistent attention to detail builds a reputation for reliability and quality.

Which method is called in Unity when two non-trigger Colliders first make contact?

Answer: OnCollisionEnter()

OnCollisionEnter() is called on the first frame two non-trigger colliders make physical contact, providing a Collision object with contact details.

What is the Dunning-Kruger effect and how does it relate to professional development?

Answer: A cognitive bias where people with limited knowledge overestimate their competence, while experts may underestimate theirs

This bias means beginners often feel more confident than justified, while experienced professionals may feel less confident despite their superior knowledge.

What is the most effective study strategy for this type of exam?

Answer: Consistent study over time using active recall, practice tests, and spaced repetition

Research consistently shows that distributed practice, active recall, and practice testing produce better retention and exam performance than passive review or cramming.

A spherical light that radiates in every direction

Answer: Point Light

A Point Light in Unity simulates a light source that emits light uniformly in all directions from a single point in space. This perfectly matches the description of a "spherical light that radiates in every direction," making it ideal for effects like a bare light bulb or a magical orb.

What is Post Processing in Unity's render pipeline used for?

Answer: Applying full-screen image effects like bloom, depth of field, and color grading after the scene is rendered

Post Processing applies image effects to the final rendered frame, enhancing visual quality with effects like bloom, motion blur, and color correction.

True/ False: The following steps are used to create a NavMesh from level geometry tagged as Navigation Static: Baking

Answer: A) True

To create a NavMesh in Unity, you first tag the relevant level geometry (e.g., floors, platforms) as 'Navigation Static' to indicate it should be considered for navigation. Then, you use the 'Bake' process within the Navigation window to generate the NavMesh, which agents can subsequently use for pathfinding. This process computes the walkable surfaces.

What does the 'Texture Type' setting 'Sprite (2D and UI)' do when importing an image in Unity?

Answer: Configures the texture for use as a 2D sprite or UI image, enabling slicing and sprite-specific import settings

Setting Texture Type to Sprite enables the Sprite Editor for slicing and configures the import pipeline for use with SpriteRenderer and UI Image components.

What is the relationship between customer satisfaction and professional success?

Answer: Satisfied clients and customers drive repeat business, referrals, and reputation, which are fundamental to professional success

Regardless of the field, the ability to satisfy clients, patients, students, or customers through quality service drives sustainable professional success.

What is the purpose of backtesting a trading strategy?

Answer: Testing a strategy against historical data to evaluate its potential performance before risking real money

Backtesting applies your strategy to historical market data to see how it would have performed, helping identify strengths, weaknesses, and realistic expectations.

What is the purpose of the EventSystem GameObject in Unity UI?

Answer: Handling and dispatching input events (click, hover, drag) to the correct UI elements

The EventSystem processes input and routes UI interaction events like pointer clicks and drags to the appropriate UI elements via raycasting.

How do you handle test anxiety effectively?

Answer: Prepare thoroughly, practice relaxation techniques, arrive early, and maintain a positive mindset

Test anxiety is best managed through a combination of thorough preparation (which builds confidence), relaxation techniques, and positive self-talk.

Which method would you use to find a GameObject in the scene by its name at runtime?

Answer: GameObject.Find()

GameObject.Find() searches the scene hierarchy by name, but it's expensive and should be cached in Start() rather than called every frame.

What is the purpose of continuing education in a profession?

Answer: To maintain and expand knowledge, meet licensing requirements, and stay competitive in the field

Continuing education ensures professionals maintain current knowledge, meet regulatory requirements, and develop new skills for career advancement.
