Question

我这里有一些代码根据this视频对声明的单词进行加扰。下面的代码取决于我在Unity Editor中声明的单词数组。问题是我希望它是动态的，就像它将单词提取到数据库中一样。我用php编写了一个从db检索数据的代码，并在csharp上编写了一个通过WWW方法读取php的代码。我不能合并这两个过程-争夺单词和从db获取单词，请帮助我，谢谢。

this是我的Unity密码设置。如您所见，我将WordScrambe.cs附加到Core Gameobject上，并声明了两个词-“ YES”和“ YOURS”。

CharObject.cs

public char character;
public Text text;

public int index;

[Header("Appearance")]
public Color normalColor;
public Color selectedColor; 

bool isSelected= false;

public CharObject Init(char c)
{
    character = c;
    text.text = c.ToString ();
    gameObject.SetActive (true); 
    return this;
}

public void Select()
{
    isSelected = !isSelected;
    image.color = isSelected ? selectedColor : normalColor;
    if (isSelected) {
        WordScramble.main.Select (this);
    } else {
        WordScramble.main.UnSelect();
    }
}
}

                    //Debug.Log(characters[indexChar]);
                    result += characters [indexChar];

        {
            StartCoroutine (CoCheckWord());
        }
        IEnumerator CoCheckWord()
        {
            yield return new WaitForSeconds (0.5f);
            string word = "";
            foreach (CharObject charObject in charobjects)
            {
                word += charObject.character;
            }
            if (word == words [currentWord].word) {
                currentWord++;
                ShowScramble (currentWord);


            }

        }
    }

下面是使用PHP从db检索数据并将数据传递给统一的代码。

read.php

    <?php
    include '../../connection.php';

    $query=mysqli_query($conn, "SELECT * FROM words");
    while($fetch=mysqli_fetch_array($query)){

        echo $get=$fetch["words"];
        echo ",";
    }

    ?>

fetch.cs-同时，我将其附加到Unity Editor的Main Camera上。

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;

    public class fetch : MonoBehaviour {


        public string[] dbWords;

         IEnumerator Start(){
            WWW words=new WWW("http://localhost/bootstrap/android/v2/read.php");
            yield return words;
            string wordsDataString=words.text;
            print(wordsDataString);
            dbWords=wordsDataString.Split(',');
        }
    }

简而言之，我想统一制作一个争夺战游戏，它的文字取决于数据库。我有单词争夺（但是是静态的）和从数据库中检索数据但没有连接到我制作的争夺游戏的过程，这意味着我的项目还不是动态的，对于未解释的解释深感抱歉。谢谢您的加油！：）

欢迎您！

目前还不清楚您的问题出在哪里，但是我想您是说您没有从数据库中收到结果吗？

让我们开始将数据库逻辑移到一个单独的类中，以进行良好的练习。同样，MonoBehaviour的Start Method的返回类型为void，而不是IENumerator。您需要一个IENumerator，可以使用StartCoroutine进行调用。

创建如下所示的单独的类

public static class NetworkManager
{
    public static IEnumerator Fetch(Action<string[]> callback)
    {
        WWW words=new WWW("http://localhost/bootstrap/android/v2/read.php");
        yield return words;
        string wordsDataString=words.text;
        print(wordsDataString);
        var result = wordsDataString.Split(',');

        callback?.Invoke(result);
    }
}

我无法测试您在Fetch方法中拥有的代码，因为您是在本地使用它的，但让我们假设它现在可以使用。

请注意将回调作为参数。这使您可以注册一个操作，该操作将在数据库调用完成后触发。

在方法的最后一行中调用它。然后，您可以像这样调用方法：

public class SomeClass : MonoBehaviour
{
    StartCoroutine(NetworkManager.Fetch( (words) => 
    {
        // Do something with the words!
        SomeMethod(words);
    });
}

协程完成后，方括号之间的所有代码都将执行。在这种情况下，将触发接受单词作为参数的“ SomeMethod”。

我希望这可以澄清并回答您的问题！
