quiz template in unity issue - visual-studio

Question

i've done this unity project following a youtube tutorial.
but i is not working can you figure out the problem??
ok so the first code is
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class AnswerScript : MonoBehaviour
{
public bool isCorrect = false;
public QuizManager quizManager;
public Color startc;
private void Start()
{
startc = GetComponent<Image>().color;
}
public void Answer()
{
if (isCorrect)
{
GetComponent<Image>().color = Color.green;
Debug.Log("Correct Answer");
quizManager.correct();
}
else
{
GetComponent<Image>().color = Color.red;
Debug.Log("Wrong Answer");
quizManager.wrong();
}
}
}
and the second is this one it is a little script
using UnityEngine;
using UnityEngine.UI;
[System.Serializable]
public class QuestionAndANWSER
{
public Image[] Question;
public string[] Answers;
public int CorrectAnswer;
}
the third is this one the biggest script:)
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class QuizManager : MonoBehaviour
{
public List<QuestionAndANWSER> Qna;
public GameObject[] options;
public int currentQuestion;
public GameObject QuizPanel;
public GameObject GOPanel;
public Text QuestionTxt;
public Text ScoreTxt;
int totalQuestions = 0;
public int score;
private void Start()
{
totalQuestions = Qna.Count;
GOPanel.SetActive(false);
generateQuestion();
}
public void retry()
{
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
}
public void GameOver()
{
QuizPanel.SetActive(false);
GOPanel.SetActive(true);
ScoreTxt.text = score +"/"+ totalQuestions;
}
public void correct()
{
score += 1;
Qna.RemoveAt(currentQuestion);
StartCoroutine(WaitforNext());
}
public void wrong()
{
Qna.RemoveAt(currentQuestion);
StartCoroutine(WaitforNext());
}
IEnumerator WaitforNext()
{
yield return new WaitForSeconds(1);
generateQuestion();
}
void SetAnswer()
{
for (int i= 0; i < options.Length; i++)
{
options[i].GetComponent<Image>().color = options[i].GetComponent<AnswerScript>().startc;
options[i].GetComponent<AnswerScript>().isCorrect = false;
options[i].transform.GetChild(0).GetComponent<Text>().text = Qna[currentQuestion].Answers[i];
if(Qna[currentQuestion].CorrectAnswer == i + 1)
{
options[i].GetComponent<AnswerScript>().isCorrect = true;
}
}
}
void generateQuestion()
{
if(Qna.Count > 0)
{
currentQuestion = Random.Range(0, Qna.Count);
QuestionTxt.text = Qna[currentQuestion].Question;
SetAnswer();
}
else
{
Debug.Log("out of questions");
GameOver();
}
}
}
it is a quiz template but i doesn't work. does anyone know how to fix that?
i am a begginer in learning c#

Answer 1

When you define a question and answer:
public class QuestionAndANWSER
{
public Image[] Question;
public string[] Answers;
public int CorrectAnswer;
}
you are storing questions as IMAGES. Later, in generateQuestion(), you're trying to use the questions as TEXT:
void generateQuestion()
{
// ...
QuestionTxt.text = Qna[currentQuestion].Question;
// ...
}
You have to be consistent in how you're handling the questions. You either need to change the QuizManager to use an image for the QuestionTxt or you need to change QuestionAndANSWER to use text for the Question.
