c# - 如何使统一不两次选择相同的数字？

Question

该程序是一个简单的猜数字游戏，但是当我将猜测随机化时，unity 往往会多次选择相同的数字，有没有办法让它知道它已经选择了哪些数字？如果它不能选择另一个号码，还有没有办法让它自动转到丢失的场景？任何帮助表示赞赏^_^

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

public class NumberGuesser : MonoBehaviour {

int min;
int max;
int guess;
int maxGuessesAllowed = 15;
public Text text;
//guess = (max + min) / 2;

// Use this for initialization
void Start () {
    min = 1;
    max = 1000;
    NextGuess();
    max = max + 1;
}

// Update is called once per frame
public void guessHigher () {
    min = guess;
    NextGuess ();
}
public void guessLower() {
        max = guess;
        NextGuess();
    }
void NextGuess(){
    guess = (max + min) / 2;
    //guess = Random.Range (min,max);//Randomizes Guesses
    //print (guess);
    text.text = guess.ToString ();
    maxGuessesAllowed = maxGuessesAllowed - 1;
    if (maxGuessesAllowed <= 0) {
        Application.LoadLevel ("Win");
    }
}
}//main

Answer 1

试试这个:

List<int> alreadyGuessed = new List<int>();
...

int NextGuess()
{
    int theGuess = Random.Range(min, max);
    while(alreadyGuessed.Contains(theGuess))
        theGuess = Random.Range(min, max);

    alreadyGuessed.Add(theGuess);
    return theGuess;
}

它会跟踪已经猜到的内容并继续猜测，直到之前没有猜到。
