I'm making a quiz game for a college project and have no experience with Unity. my codes from madfireon Is it possible to reset the timer after changing the question?

using System.Collections; using System.Collections.Generic; using UnityEngine; using System; using UnityEngine.UI; using UnityEngine.SceneManagement;

public class QuestionManager : MonoBehaviour { [SerializeField] private QuestionUi questionUi; [SerializeField]private List questions; [SerializeField] private float timeLimit = 30f; private Question selectedQuestion; private int scoreCount = 0; private int highscore = 0; private float currentTime; private GameStatus gameStatus = GameStatus.Next; public GameStatus GameStatus { get { return gameStatus; } }

 public void Start()
 {
    
     scoreCount = 0;
     currentTime = timeLimit; 
     SelectQuestion();
     gameStatus = GameStatus.Playing;
     
 }
  
 void SelectQuestion()
 {
     int val = UnityEngine.Random.Range(0, questions.Count);
     selectedQuestion = questions[val];
     questionUi.SetQuestion(selectedQuestion);
     questions.RemoveAt(val);

 }

 private void Update()
 {
     
     if (gameStatus == GameStatus.Playing)
     {
         highscore = PlayerPrefs.GetInt("highscore", 0);
         currentTime -= Time.deltaTime;
         SetTimer(currentTime);
     }
 }
 private void SetTimer(float value)
 {
     TimeSpan time = TimeSpan.FromSeconds(currentTime);
     questionUi.TimerText.text =  time.ToString("mm':'ss");
     if (currentTime < 0)
     {
         gameStatus = GameStatus.Next;
         questionUi.GameOverPanel.SetActive(true);
        
     }

 }






 public bool Answer(string answered)
 {
     bool correctAns = false;
     if (answered == selectedQuestion.correctAns)

     {
         correctAns = true;
         scoreCount += 1;
         questionUi.ScoreText.text = "" + scoreCount;
         questionUi.HighScoreText.text = highscore + "";
         if (highscore < scoreCount)
         {
             PlayerPrefs.SetInt("highscore", scoreCount);
             highscore = scoreCount;
         }
        
     }
    
         
     
     else
     {
         
     }

 
    



 if (gameStatus == GameStatus.Playing)
 {
     if (questions.Count > 0)
     {
         Invoke("SelectQuestion", 0.4f);
     }
     else
     {
         gameStatus = GameStatus.Next;
         questionUi.GameOverPanel.SetActive(true);
     }
 }
     
     return correctAns;
 }
 public void TryButton()
 {
     
     SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
 }

}

[System.Serializable] public class Question { public string questionInfo; public QuestionType questionType; public List options; public string correctAns; }

     [System.Serializable]

public enum QuestionType { TEXT } public enum GameStatus { Next, Playing }
