Adaface Sample Unity Questions

Consider the following Unity3D scenario where you are tasked with optimizing a game's configuration settings using Scriptable Objects for data-driven design. Examine the given ScriptableObject script and answer the question: How can you ensure that data from multiple Scriptable Objects are properly aggregated and utilized at runtime without creating unnecessary instances?

using UnityEngine;
            
            [CreateAssetMenu(fileName = "GameConfig", menuName = "Configurations/GameConfig")]
            public class GameConfig : ScriptableObject {
                public string configName;
                public int maxEnemies;
                public float enemySpawnRate;
            
                public void DisplayConfig() {
                    Debug.Log($"Config: {configName}, Max Enemies: {maxEnemies}, Spawn Rate: {enemySpawnRate}");
                }
            }

Options:
            A: Use static variables in ScriptableObject for data access
            B: Instantiate ScriptableObjects on script load
            C: Reference ScriptableObjects in MonoBehaviour scripts using Inspector
            D: Load all ScriptableObjects at runtime using Resources.Load
            E: Use a Singleton to manage ScriptableObject instances
            F: Merge data manually during runtime in a central manager

You are tasked with creating a system that spawns enemies in Unity3D using prefabs. The prefab `EnemyPrefab` has a script attached, `EnemyBehavior`, which contains a public integer field `damage`. The goal is to instantiate this prefab at random positions within a specified area. Consider the following code snippet:

using System.Collections;
            using UnityEngine;
            
            public class EnemySpawner : MonoBehaviour {
                public GameObject enemyPrefab;
                public Vector3 areaSize;
                public int enemyCount;
            
                void Start() {
                    for (int i = 0; i < enemyCount; i++) {
                        InstantiateEnemy();
                    }
                }
            
                void InstantiateEnemy() {
                    Vector3 randomPosition = new Vector3(
                        Random.Range(-areaSize.x / 2, areaSize.x / 2),
                        0,
                        Random.Range(-areaSize.z / 2, areaSize.z / 2)
                    );
                    GameObject enemy = Instantiate(enemyPrefab, randomPosition, Quaternion.identity);
                    enemy.GetComponent<EnemyBehavior>().damage = Random.Range(10, 50);
                }
            }

Consider the above code snippet and choose the correct statement about how the prefabs will be instantiated and configured. 
            
            A: Enemies will spawn at fixed intervals 
            B: The enemies' y-coordinate will be random 
            C: Each enemy will most likely have a unique damage value 
            D: Prefabs will need to be set manually in the inspector 
            E: Quaternions are not used for rotation in instantiation

In a multiplayer Unity3D game using the UNet HLAPI, you want to implement a client-side prediction feature to reduce perceived latency. Consider the following pseudo code that represents a movement synchronization system between client and server:

struct PlayerState {
                Vector3 position;
                Quaternion rotation;
                float timestamp;
            }
            
            class Player : NetworkBehaviour {
                Queue<PlayerState> _stateBuffer;
                Vector3 _lastKnownPosition;
                Quaternion _lastKnownRotation;
                
                void Update() {
                    if (isLocalPlayer) {
                        CmdSendInputToServer(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
                    } else {
                        InterpolatePlayerState();
                    }
                }
            
                [Command]
                void CmdSendInputToServer(float h, float v) {
                    Vector3 movement = new Vector3(h, 0, v);
                    PlayerState state = new PlayerState {
                        position = transform.position + movement * Time.deltaTime,
                        rotation = transform.rotation,
                        timestamp = Time.time
                    };
                    RpcSyncStateWithClients(state);
                }
            
                [ClientRpc]
                void RpcSyncStateWithClients(PlayerState state) {
                    _stateBuffer.Enqueue(state);
                }
            
                void InterpolatePlayerState() {
                    // Detail on interpolation logic
                }
            }

Which of the following best describes the function and interaction of this synchronization mechanism in handling client prediction and latency?

A: The predictions occur server-side and all clients receive delayed updates leading to smooth rendering.
            B: Clients interpolate state using immediate server responses improving local movement fluidity.
            C: Server commands constrain client input ensuring prediction accuracy at the cost of responsiveness.
            D: Clients run prediction logic locally and periodically reconcile with server states to reduce perceived latency.
            E: Rotation synchronization suffices for latency compensation eliminating prediction necessity.
            F: State buffering on clients introduces latency in movement handling but helps in network event logging.
