Question

所以我已经按照Unity Quiz游戏的教程进行了操作，并想知道如果我希望游戏只提出最多10个问题，但问题池有20个左右，所以这是教程中的脚本，我有点编辑。

我有一个名为Game Controller的脚本

void Start()
        {
            dataController = FindObjectOfType<DataController>();                                // Store a reference to the DataController so we can request the data we need for this round

        currentRoundData = dataController.GetCurrentRoundData();                            // Ask the DataController for the data for the current round. At the moment, we only have one round - but we could extend this
        questionPool = currentRoundData.questions;                                          // Take a copy of the questions so we could shuffle the pool or drop questions from it without affecting the original RoundData object

        timeRemaining = currentRoundData.timeLimitInSeconds;                                // Set the time limit for this round based on the RoundData object
        UpdateTimeRemainingDisplay();
        playerScore = 0;
        questionIndex = 0;

        ShowQuestion();
        isRoundActive = true;
    }


void ShowQuestion()
    {
        RemoveAnswerButtons();

        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[i]);                                    // Pass the AnswerData to the AnswerButton so the AnswerButton knows what text to display and whether it is the correct answer
        }
    }

持有问题和答案的脚本

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class DataController : MonoBehaviour 
{
    public RoundData[] allRoundData;

    void Start ()  
    {
        DontDestroyOnLoad (gameObject);

        SceneManager.LoadScene ("MenuScreen");
    }

    public RoundData GetCurrentRoundData()
    {
        return allRoundData [0];
    }
}

Answer 1

你有一堆问题，其中20个正如你所说，现在你想要随机抽出10个：

Question [] questions = GetQuestions(); // This gets all questions as array
List<Question> list = new List<Question>(questions); // turn into list
int maxAmount = 10; // Set amount of questions
for(int i = 0; i < maxAmount; i++)
{
    int random = Random.Range(0, list.Count); // Random number between 0 and Count (excluded)
    Question question = list[random];  // Get the question
    CreateQuestion(question);
    list.RemoveAt(random);  // Remove it from the list, not the array
}
