Question

我正在Unity3d中进行一个问答游戏，我想表明玩家在哪个级别上依赖于他/她已经回答的问题。只是为了让我看看它是否有效我试图让每个问题都算作一个级别（之后我会弄清楚）。我知道我想使用哪些代码行，但我不知道在哪里放置它们才能正常工作。

这些是我想要使用的行：

levelValue = levelValue + 1;
Level.text = "Level:" + levelValue.ToString();

这是我的代码：

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

public class GameManager : MonoBehaviour {

public Question[] questions;
private static List<Question> unansweredQuestions;

private Question currentQuestion;

public Text Level;

[SerializeField]
private Text factText;

[SerializeField]
private Text trueAnswerText;
[SerializeField]
private Text falseAnswerText;

[SerializeField]
private Animator animator;

[SerializeField]
private float timeBetweenQuestions = 1f;

int i = 0;
int levelValue = 0;



void Start()
{

    if (unansweredQuestions == null || unansweredQuestions.Count == 0)
    {
        unansweredQuestions = questions.ToList<Question>();
    }

    SetCurrentQuestion();


}


void SetCurrentQuestion()
{
    int questionIndex = i;
    currentQuestion = unansweredQuestions[questionIndex];
    i = i + 1;




    factText.text = currentQuestion.fact;


    if (currentQuestion.isTrue)
    {
        trueAnswerText.text = "ΣΩΣΤΟ";
        falseAnswerText.text = "ΛΑΘΟΣ";
    }else
    {
        trueAnswerText.text = "ΛΑΘΟΣ";
        falseAnswerText.text = "ΣΩΣΤΟ";
    }


}

IEnumerator TransitionToNextQuestion ()
{
    unansweredQuestions.Remove(currentQuestion);

    yield return new WaitForSeconds(timeBetweenQuestions);

    SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);


}

public void UserSelectTrue ()
{
    animator.SetTrigger("True");
    if (currentQuestion.isTrue)
    {
        Debug.Log("CORRECT!");
    }else
    {
        Debug.Log("WRONG!");
    }

    StartCoroutine(TransitionToNextQuestion());
}

public void UserSelectFalse()
{
    animator.SetTrigger("False");
    if (!currentQuestion.isTrue)
    {
        Debug.Log("CORRECT!");
    }
    else
    {
        Debug.Log("WRONG!");
    }

    StartCoroutine(TransitionToNextQuestion());
}
}

假设每个问题的代码都相同，我建议您设置

int levelValue = 0;

像这样静态

：

private static int levelValue;

在C＃中，未初始化的int的默认值为零。

如果您希望计数器从0开始（例如计算您已回答的问题数量），或者在脚本开头（如果您希望从1开始计算），则更改levelValue应该在更改级别之前发生（例如你现在的问题）。

在第一种情况下，它应该是这样的：

IEnumerator TransitionToNextQuestion ()
{
    unansweredQuestions.Remove(currentQuestion);

    yield return new WaitForSeconds(timeBetweenQuestions);
    levelValue++;
    SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
}

或在后一种情况下：

void Start()
{

    if (unansweredQuestions == null || unansweredQuestions.Count == 0)
    {
        unansweredQuestions = questions.ToList<Question>();
    }
    levelValue++;
    SetCurrentQuestion();
}

现在关于在哪里设置Text值，您可以将它放在Unity的Update方法

中

void Update(){
    Level.Text= String.Format("Level: {0}",levelValue);
}

或在您的Start方法中。

还为您的代码提示：如果要将int值增加1，请使用operator ++。示例

i++; //THIS has the same effect as this  i = i + 1;

祝您的项目顺利，如果您有任何其他信息或疑问，请随时与我联系。
