퀴즈게임 제작

퀴즈 카드 보여주는 방식 변경

• 세번째 카드를 오브젝트풀에 반환하는 형태로 변경

private void ChangeQuizCard()
    {
        var temp = _firstQuizCardObject; //임시로 저장
        _firstQuizCardObject = _secondQuizCardObject;
        _secondQuizCardObject = ObjectPool.Instance.GetObject(); //새로 만들기

        SetQuizCardPosition(_firstQuizCardObject, 0); //순서 지정
        SetQuizCardPosition(_secondQuizCardObject, 1);
        
        ObjectPool.Instance.ReturnObject(temp); //반환
    }

퀴즈 데이터를 읽어와 카드에 표시 

• csv파일로 되어있는 퀴즈 데이터 읽어오기

    {
        // 1. 퀴즈
        // 2. 설명
        // 3. 타입 (0: OX퀴즈, 1: 보기 3개 객관식)
        // 4. 정답
        // 5. 보기 (1,2,3)
        
        // 퀴즈 데이터 표현
        questionText.text = quizData.question;
        //descriptionText.text = quizData.description;
        var firstButtonText = optionButtons[0].GetComponentInChildren<TMP_Text>();
        firstButtonText.text = quizData.firstOption;
        var secondButtonText = optionButtons[1].GetComponentInChildren<TMP_Text>();
        secondButtonText.text = quizData.secondOption;

        thirdButtonText.text = quizData.thirdOption;
        
        this.onCompleted = onCompleted;
    }
}

• 이후 InitQuizCards( )에서 초기화

퀴즈 카드 순서대로 표시

• 마지막으로 로드된 카드의 인덱스를 int변수로 추적
• 카드 교환될 때마다 2번쨰 카드에 데이터 입력

private void ChangeQuizCard()
    {
        if (_lastGeneratedQuizIndex >= MAX_QUIZ__COUNT) return;
        
        var temp = _firstQuizCardObject; //임시로 저장
        _firstQuizCardObject = _secondQuizCardObject;
        _secondQuizCardObject = ObjectPool.Instance.GetObject(); //새로 만들기

        if (_lastGeneratedQuizIndex < _quizDataList.Count -1)
        {
            _lastGeneratedQuizIndex++;
            _secondQuizCardObject.GetComponent<QuizCardController>().SetQuiz(_quizDataList[_lastGeneratedQuizIndex], OnCompletedQuiz);
        }
        
        SetQuizCardPosition(_firstQuizCardObject, 0); //순서 지정
        SetQuizCardPosition(_secondQuizCardObject, 1);
        
        ObjectPool.Instance.ReturnObject(temp); //반환
    }
