我这里有代码，可以根据 this 对声明的单词进行加扰video.Below 是依赖于我在 Unity Editor 上声明的单词数组的代码。问题是我希望它是动态的，就像它会将单词提取到数据库中一样。我在 php 中编写了一个代码，用于从 db 检索数据，并在 csharp 上编写了一个代码，该代码通过 WWW 方法读取 php。我无法合并这两个过程 - 打乱单词和从 db 获取单词，请帮助我，谢谢。
this是我的 Unity 拼词设置。如您所见，我将 WordScrambe.cs 附加到 Core Gameobject 并声明了 2 个词——“YES”和“YOURS”。
字符对象.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class CharObject : MonoBehaviour {
public char character;
public Text text;
public Image image;
public RectTransform rectTransform;
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();
}
}
}
WordScramble.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[System.Serializable]
public class Word
{
public string word;
[Header("leave empty if you want randomized")]
public string desiredRandom;
public string GetString()
{
if (!string.IsNullOrEmpty (desiredRandom))
{
return desiredRandom;
}
string result = word;
while (result==word)
{
result = "";
List<char> characters = new List<char> (word.ToCharArray ());
while (characters.Count > 0)
{
int indexChar = Random.Range (0, characters.Count - 1);
//Debug.Log(characters[indexChar]);
result += characters [indexChar];
Debug.Log(word);
characters.RemoveAt (indexChar);
}
}
return result;
}// end of Getstring Method
}
public class WordScramble : MonoBehaviour {
public Word[] words;
[Header("UI REFERENCE")]
public CharObject prefab;
public Transform container;
public float space;
public float lerpSpeed=5;
List<CharObject> charobjects = new List<CharObject>();
CharObject firstSelected;
public int currentWord;
public static WordScramble main;
void Awake()
{
main = this;
}
// Use this for initialization
void Start () {
ShowScramble (currentWord);
}
// Update is called once per frame
void Update ()
{
RepositionObject ();
}
void RepositionObject()
{
if (charobjects.Count==0) {
return;
}
float center = (charobjects.Count -1) / 2;
for (int i = 0; i < charobjects.Count; i++)
{
charobjects[i].rectTransform.anchoredPosition= Vector2.Lerp(charobjects[i].rectTransform.anchoredPosition, new Vector2((i- center)* space, 0), lerpSpeed* Time.deltaTime) ;
charobjects [i].index = i;
}
}
//show a random word to the screen
public void ShowScramble()
{
ShowScramble (Random.Range (0, words.Length - 1));
}
//<summary>Show word from collection with desired index
public void ShowScramble(int index)
{
charobjects.Clear ();
foreach (Transform child in container) {
Destroy (child.gameObject);
}
//Words Finished
if (index > words.Length - 1) {
Debug.LogError ("index out of range, please enter range betwen 0-" + (words.Length - 1).ToString ());
return;
}
char[] chars = words [index].GetString ().ToCharArray ();
foreach (char c in chars)
{
CharObject clone = Instantiate (prefab.gameObject).GetComponent<CharObject> ();
clone.transform.SetParent (container);
charobjects.Add (clone.Init (c));
}
currentWord = index;
}
public void Swap(int indexA, int indexB)
{
CharObject tmpA = charobjects [indexA];
charobjects[indexA] = charobjects [indexB];
charobjects[indexB] = tmpA;
charobjects [indexA].transform.SetAsLastSibling ();
charobjects [indexB].transform.SetAsLastSibling ();
CheckWord ();
}
public void Select(CharObject charObject)
{
if (firstSelected)
{
Swap (firstSelected.index, charObject.index);
//Unselect
firstSelected.Select();
charObject.Select();
} else {
firstSelected = charObject;
}
}
public void UnSelect()
{
firstSelected = null;
}
public void CheckWord()
{
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 从数据库中检索数据并将数据传递给 unity 的代码。
读取.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-我同时将其附加到 Unity Editor 上的 Main Camera。
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(',');
}
}
总之我想在unity中做一个scramble game，它的话依赖于数据库。我有单词争夺(但静态)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，对于不清楚的解释我很抱歉。 谢谢你和更多的力量! :)
最佳答案
欢迎来到 SO!
目前还不完全清楚您的问题出在哪里，但我认为您的意思是说您没有从数据库中收到结果？
让我们首先将您的数据库逻辑移动到一个单独的类中，以获得良好的实践。 此外，MonoBehaviour 的 Start 方法的返回类型为 void，而不是 IENumerator。您需要一个 IENumerator，您可以使用 StartCoroutine 调用它。
像下面这样创建一个单独的类
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);
}
}
我无法测试您的 Fetch 方法中的代码，因为您是在本地使用它，但我们假设它现在可以正常工作。
注意回调作为参数。 这允许您注册一个将在数据库调用完成后触发的操作。
它在方法的最后一行被调用。 然后您可以像这样调用该方法:
public class SomeClass : MonoBehaviour
{
StartCoroutine(NetworkManager.Fetch( (words) =>
{
// Do something with the words!
SomeMethod(words);
});
}
一旦协程完成，括号内的任何代码都会被执行。在这种情况下，将触发接受单词作为参数的“SomeMethod”。
我希望这能澄清并回答您的问题!
