Start()

FixedUpdate()

LateUpdate()

Update()

Which Unity function is called every frame to update game logic?

GameObject.Find("ObjectName")

GetComponent<Rigidbody>()

Instantiate(Prefab)

Object.FindScene()

How do you reference a GameObject in a script using the Unity API?

MeshRenderer

Collider

Rigidbody

Transform

Which Unity component allows a GameObject to be affected by physics?

Change its scope to public

Use [SerializeField] before the variable

Mark it with the "private" keyword

Place it inside Start()

How do you make a private variable visible in the Unity Inspector?

SceneManager.LoadSceneAsync("SceneName", LoadSceneMode.Additive)

DontDestroyOnLoad()

Application.LoadLevel()

AssetBundle.Load()

Which system allows you to load a new scene while keeping the current one active?

Render UI elements efficiently

Handle input processing

Run physics calculations at a constant rate

Call functions once at game startup

What is the primary purpose of FixedUpdate()?

ScriptableObjects

MonoBehaviour

ScriptableObject

Which Unity feature enables efficient data storage without needing GameObjects in a scene?

rigidbody.velocity = new Vector3(x, y, z)

transform.position += new Vector3(x, y, z)

 rigidbody.AddForce(new Vector3(x, y, z), ForceMode.Impulse)

OnCollisionEnter()

How do you apply force to an object in Unity’s physics system?

OnTriggerStay()

OnMouseOver()

Which Unity method is used to detect collisions between objects that both have Rigidbody components?

Set its transform parent to null

Call DontDestroyOnLoad(this.gameObject)

Change its layer to PersistentObjects

Use GameObject.Destroy()

How do you prevent a GameObject from being destroyed when switching scenes?

Python

JavaScript

Which programming language is primarily used in Unreal Engine for game logic?

Actor

GameMode

Pawn

LevelSequence

Which Unreal component represents a physical object in the game world?

Use UCLASS() before the class declaration

Use standard C++ class syntax

Create an Actor without macros

Use #define ClassType

How do you define a class in Unreal that supports reflection and Blueprint exposure?

BeginPlay()

SetupPlayerInputComponent()

Tick()

What is the default function for handling player input in an Actor or Pawn?

Mark it as public in C++

Use BlueprintCallable and BlueprintReadWrite macros

Declare it as static

Store it in a UI Widget

How do you access and modify a variable across multiple Blueprints in Unreal?

Unreal’s Replication System

NetworkManager

AsyncTasks

SceneManager

Which system in Unreal is used for multiplayer network replication?

It runs logic every frame for the object it belongs to

It only executes when triggered by an event

It initializes objects before the game starts

 It handles physics calculations

What is the function of Tick(float DeltaTime) in Unreal Engine?

It executes game logic once when the Actor is spawned

It is the main loop for game rendering

It handles UI animations

It updates AI movement every frame

What is the purpose of the BeginPlay() function in Unreal Engine?

APlayerController

UGameInstance

ALevelScriptActor

FTransform

Which Unreal Engine class is responsible for controlling a player character?

Mark variables as public

Use UPROPERTY(EditAnywhere, BlueprintReadWrite)

Declare them as global variables

Use static_cast<> conversion

How do you efficiently expose C++ variables to Blueprints while keeping encapsulation intact?
