How to randomize answers?

HI, I have followed the Unity quiz Game Tutorial and would want to further improve the game. I would like to set it up so that the answers data are showing up randomly. Can anyone help me?
Here AnswerButton Script:

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class AnswerButton : MonoBehaviour 
{
	public Text answerText;
	private GameController gameController;
	private AnswerData answerData;

	void Start()
	{
		gameController = FindObjectOfType<GameController>();
	}

	public void SetUp(AnswerData data)
	{		
		answerData = data;
		answerText.text = answerData.answerText;
	}
	
	
	public void HandleClick()
	{
		gameController.AnswerButtonClicked(answerData.isCorrect);
	}
}

Game Controller Script:

void ShowQuestion()
    {
        RemoveAnswerButtons();
		ChooseQuestion(); // random question is succsessfull
		
        QuestionData questionData = questionPool[questionIndex];                            // Get the QuestionData for the current question
        questionText.text = questionData.questionText;                                      // Update questionText with the correct text
		
        for (int i = 0; i < questionData.answers.Length; i++)                               // For every AnswerData in the current QuestionData...
        {
            GameObject answerButtonGameObject = answerButtonObjectPool.GetObject();         // Spawn an AnswerButton from the object pool
            answerButtonGameObjects.Add(answerButtonGameObject);
            answerButtonGameObject.transform.SetParent(answerButtonParent);
            answerButtonGameObject.transform.localScale = Vector3.one;

            AnswerButton answerButton = answerButtonGameObject.GetComponent<AnswerButton>();
            answerButton.SetUp(questionData.answers*);                                    // Pass the AnswerData to the AnswerButton so the AnswerButton knows what text to display and whether it is the correct answer*

}
}

  • void ChooseQuestion()*

  • {*

  •  bool questionChosen = false;*
    
  •  while(questionChosen != true) // While question chosen does not equal true*
    
  •  {*
    
  •  	int random = Random.Range(0, questionPool.Length); // Choose a random number between 0 and the questionPool length*
    
  •  	if (!questionIndexesChosen.Contains(random)) // If the new list doesn't contain the number*
    
  •  	{*
    
  •  		questionIndexesChosen.Add(random); // Add the number to the list*
    
  •  		questionIndex = random; // Set the questionIndex to the number*
    
  •  		questionChosen = true; // Set questionChosen to true to end the while loop*
    
  •  	}*
    

}

  • }*

void RemoveAnswerButtons()
{
while (answerButtonGameObjects.Count > 0) // Return all spawned AnswerButtons to the object pool
{
answerButtonObjectPool.ReturnObject(answerButtonGameObjects[0]);
answerButtonGameObjects.RemoveAt(0);
}
}

public void AnswerButtonClicked(bool isCorrect)
{
if (isCorrect)
{
playerScore += currentRoundData.pointsAddedForCorrectAnswer; // If the AnswerButton that was clicked was the correct answer, add points
scoreDisplay.text = playerScore.ToString();

  •  	scoreDisplay1.text = playerScore.ToString();*
    

}
if(qNumber < questionPool.Length - 1) // If there are more questions, show the next question
{
qNumber++;
ShowQuestion();
}
else // If there are no more questions, the round ends
{
EndRound();
}
}

I did not read the code.

But if you want to randomize something, you need to use Random.Range utility.

Assign a int number to each answer, and use the Random.Range to choose one.
