Question

我一般是C＃初学者，尝试在Unity中创建日语日语单词键入游戏，该游戏中屏幕上显示的单词/字母将以平假名显示，但请求的输入为Romaji（字母）字母。

目前，我陷入困境，试图弄清楚每个单词一次如何生成随机数。执行加（word）操作。例如，当创建Word对象时，生成一个随机数。然后，将该随机数用于依赖它的类，例如getWord_Hiragana和getWord_Romaji。互联网上存在的大多数打字游戏都只显示一个对象（英语），所以我找不到我需要的东西。

// WordManager.cs
public class WordManager : MonoBehaviour {

    public List<Word> words;

    public WordSpawner wordSpawner;

    public void AddWord ()
    {
        Word word = new Word (WordGenerator.GetWord_Romaji(), wordSpawner.SpawnWord());

        words.Add (word);
    }
}

// WordGenerator.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class WordGenerator : MonoBehaviour {

    public static string[] wordList_Hiragana = {    "あ", "い", "う", "え", "お" };

    public static string[] wordList_Katakana = {    "ア", "イ", "ウ", "エ", "オ" };

    public static string[] wordList_Romaji = {      "a", "i", "u", "e", "o" };

    public static int GetIndex ()
    {
        int index = Random.Range (0, wordList_Romaji.Length - 1);   // Get Random number which has the same index for Hiragana, Katakana, and Romaji arrays

        Debug.Log ("Index #" + index + ": " + wordList_Hiragana[index] + " " + wordList_Katakana[index] + " " + wordList_Romaji[index]); // Debug Log

        return index; // Returns the result of the random as a guidance.
    }


    public static string GetWord_Hiragana ()    // A function to return the result of GetIndex as Hiragana word to be used on WordManager and in turn, displays that Hiragana.
    {
        int index = GetIndex ();

        string getWord_Hiragana = wordList_Hiragana [index];
        return getWord_Hiragana;
    }

    public static string GetWord_Romaji ()  
    {
        int index = GetIndex ();
        string getWord_Romaji = wordList_Romaji [index];

        return getWord_Romaji;
    }
}

// Word.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class Word {

    public string word;
    private int typeIndex; // Checks for current letter

    WordDisplay display;

    public Word (string _word, WordDisplay _display)  // Displays the word as Hiragana / Katakana
    {
        word = _word;

        display = _display;
        display.SetWord (word);
    }

    public char GetNextLetter ()
    {
        return word[typeIndex]; // Gets the next letter of the Romaji array
    }

    public void TypeLetter ()
    {
        typeIndex++;
    }

    public bool WordTyped ()
    {
        bool wordTyped = (typeIndex >= word.Length); // Checks if the whole word has been typed
        if (wordTyped) 
        {
            display.RemoveWord (); // Remove the whole object on screen
        }
        return wordTyped;
    }
}

预期结果是GetIndex为每个Word对象滚动随机数一次。执行getWord_Romaji时，它将获取GetIndex的返回值。执行getWord_Hiragana时也是如此。现在，GetIndex被执行两次，并在每个Word对象中两次生成一个随机数，导致Debug上出现的单词与游戏屏幕上出现的单词不同。我该如何工作？

如果上面的代码不足以解决问题，则将项目发布到here。

Answer 1

在没有看到Word的实现的情况下，我会从您的示例中说它实际上确实仅对GetIndex()调用了一次，即GetWord_Romaji()。 ..

无论如何，快速简单的修补程序可能是

private static int randomizedIndex;

public static void NewRandomIndex()
{
    randomizedIndex = Random.Range (0, wordList_Romaji.Length - 1);

    Debug.Log("Index #" + randomizedIndex + ": " + wordList_Hiragana[randomizedIndex] + " " + wordList_Katakana[randomizedIndex] + " " + wordList_Romaji[randomizedIndex]);
}

public static string GetWord_Hiragana()
{
    return wordList_Hiragana[randomizedIndex];
}

public static string GetWord_Romaji ()  
{
    return wordList_Romaji[randomizedIndex];
}

并调用它

public void AddWord ()
{
    WordGenerator.NewRandomIndex();

    Word word = new Word(WordGenerator.GetWord_Romaji(), wordSpawner.SpawnWord());
    words.Add (word);
}

如果您希望以后能够在这些数组之间“翻译”单词，那么您应该使用Word而不是检索string来存储使用过的randomizedIndex并获取{ {1}}的价值“即时”。

Answer 2

我会将您的MultibodyPlant::SetFreeBodyPose()类构造函数更改为以下内容：

Word

请注意，我添加了另一个字段来存储为该特定单词实例选择的索引。

如何将随机数一次滚动到多个类上？
