Question

我正在尝试创建一个文字游戏（代码here）。我希望将单词分配给从屏幕顶部生成并掉到底部的3个敌人。这是敌人的脚本：

public class Enemy : MonoBehaviour {

public float fallSpeed = 1.0f;    

void Update () {
    transform.Translate(0, -fallSpeed * Time.deltaTime, 0);
    }
}

以下是“ spawner”一词：

public class WordSpawner : MonoBehaviour {

public GameObject wordPrefab;
public GameObject enemy;
public Transform wordCanvas;

public WordDisplay SpawnWord()
{

    Vector3 randomPosition = new Vector3(UnityEngine.Random.Range(-2.0f, 2.0f), 7.0f, 0);
    GameObject wordObj = Instantiate(wordPrefab, randomPosition, Quaternion.identity, wordCanvas);
    WordDisplay wordDisplay = wordObj.GetComponent<WordDisplay>();
    return wordDisplay;
  }     
}

这是计时器一词：

public class Wordimer : MonoBehaviour {

public WordManager wordManager;
public float delay = 1.5f;
private float nextWord = 0f;

void Update()
{
    if (Time.time >= nextWord)
    {
        wordManager.AddWord();
        nextWord = Time.time + delay;
        delay *= 0.95f;
       }
    }
}

上面脚本中的AddWord（）方法是从单词列表中随机生成单词的方法。这是添加单词方法（此方法在单独的文件中）：

public void AddWord()
{
    WordDisplay wordDisplay = wordSpawner1.SpawnWord();

    Word word = new Word(WordGenerator.GetRandomWord(), wordDisplay);

    words.Add(word); 
}

所以我希望将这些单词与敌人的游戏对象一起生成。现在，它们自己产生。如何实现此功能？

修改

这是产生敌人的脚本：

public GameObject enemy;
public float spawnTime = 3.0f;
public Transform[] spawnPoints;    

void Start () {
    InvokeRepeating("Spawn", spawnTime, spawnTime);
}

void Spawn()
{               
    int spawnPointIndex = Random.Range(0, spawnPoints.Length);        
    Instantiate(enemy, spawnPoints[spawnPointIndex].position, spawnPoints[spawnPointIndex].rotation);
}

如果我正确理解了您的问题，那么您试图归档的内容就是生成WordDisplay并将其保持在相应enemy对象的旁边，该对象已经在WordSpawner中

您可以将其分配给某个Enemy，让敌人像这样更新位置

public class Enemy : MonoBehaviour 
{
    public float fallSpeed = 1.0f;    

    public WordDisplay assosiatedDisplay;

    // optional for allways showing the text e.g. 10 cm above enemies
    public Vector3 offset = new Vector3(0, 0.1f, 0);

    void Update () 
    {
        transform.Translate(0, -fallSpeed * Time.deltaTime, 0);

        if(assosiatedDisplay)
        {
            // keep the referenced wordDisplay positioned relative to this object
            assosiatedDisplay.transform.position = transform.position + offset;
        }
    }
}

然后在生成associatedDisplay时设置WordDisplay值

public class WordSpawner : MonoBehaviour 
{
    public GameObject wordPrefab;
    public GameObject enemy;
    public Transform wordCanvas;

    public WordDisplay SpawnWord()
    {
        GameObject wordObj = Instantiate(wordPrefab, enemy.transform.position * new Vector3(1, 1, 0), Quaternion.identity, wordCanvas);
        WordDisplay wordDisplay = wordObj.GetComponent<WordDisplay>();

        // assign it to the enemy
        enemy.GetComponent<Enemy>().assosiatedDisplay = wordDisplay;

        return wordDisplay;
   }     
}

更新

我在您的问题中看不到，也不知道在哪里调用所有方法。但是，当实例化敌人对象时，您将以相同的方式存储enemy引用：

var enemy = Instantiate(enemy, spawnPoints[spawnPointIndex].position, spawnPoints[spawnPointIndex].rotation);

，然后将该enemy引用传递给public WordDisplay SpawnWord()，例如

public WordDisplay SpawnWord(Enemy enemy)
{
    // ...

    // assign it to the enemy
    enemy.assosiatedDisplay = wordDisplay;
}

给敌人分配随机文本
