Unity实例化如何管理克隆对象

Question

按照一个2D游戏教程创建怪物的怪物脚产脚本看起来像

public class MonsterSpawner : MonoBehaviour
{

    [SerializeField]
    private GameObject[] monsterReference;

    private GameObject spawnedMonster;

    [SerializeField]
    private Transform leftPos, rightPos;

    private int randomIndex;
    private int randomSide;

    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(SpawnMonsters());
    }

    IEnumerator SpawnMonsters() {

        while (true) {

            yield return new WaitForSeconds(Random.Range(1, 5));

            randomIndex = Random.Range(0, monsterReference.Length);
            randomSide = Random.Range(0, 2);

            spawnedMonster = Instantiate(monsterReference[randomIndex]);

            // left side
            if (randomSide == 0)
            {

                spawnedMonster.transform.position = leftPos.position;
                spawnedMonster.GetComponent<Monster>().speed = Random.Range(4, 10);

            }
            else
            {
                // right side
                spawnedMonster.transform.position = rightPos.position;
                spawnedMonster.GetComponent<Monster>().speed = -Random.Range(4, 10);
                spawnedMonster.transform.localScale = new Vector3(-1f, 1f, 1f);

            }
}}}

我的问题：每1-5秒钟，一个新的怪物被克隆到何处，对象内存管理发生在哪里，以及我如何处理/管理/如何处理/管理/更改特定对象（在C＃中，我将有一个列表，可以通过mymonsters [i]）

编辑注：我希望知道是否有一种获取和管理其内存的方法（让我们说销毁它们）而无需从教程更改代码（假设我想创建一个新的游戏经理类）

实例化将对象作为场景中的gameObject创建。内存是在场景层次结构中管理的。只要它是场景中的游戏对象，数据就存储在其中。

为了保留对GameObject的引用，您必须添加GameObject的列表，然后将实例化的GameObject添加到该列表中。要销毁GameObject，您必须调用destrot destrot（Monster）。

我添加了您的代码，并在所有产卵的怪物中添加了列表。我还添加了一部分，当场景中有3个怪物时，会破坏怪物。

快速注意：我将所有内容都公开了，因为它通常更容易调试，因为您可以实时看到所有值。

public class MonsterSpawner : MonoBehaviour

    public GameObject[] monsterReference;

    public GameObject spawnedMonster;
    public List<GameObject> previouslySpawnedMonsters = new List<GameObject>();

    public Transform leftPos, rightPos;

    public int randomIndex;
    public int randomSide;

    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(SpawnMonsters());
    }

    IEnumerator SpawnMonsters()
    {
        int count = 0;
        while (true)
        {
            yield return new WaitForSeconds(Random.Range(1, 5));
            if (previouslySpawnedMonsters.Count > 3)
            {
                //get the monster to destroy
                GameObject monsterToDestroy = previouslySpawnedMonsters[0];

                //destroy the monster if it was spawned last round
                Destroy(monsterToDestroy);

                //remove the reference to the monster from our list of monsters
                previouslySpawnedMonsters.RemoveAt(0);
            }

            randomIndex = Random.Range(0, monsterReference.Length);
            randomSide = Random.Range(0, 2);

            spawnedMonster = Instantiate(monsterReference[randomIndex]);
            spawnedMonster.name = "monster " + count;
            count++;
            previouslySpawnedMonsters.Add(spawnedMonster);

            // left side
            if (randomSide == 0)
            {
                spawnedMonster.transform.position = leftPos.position;
                spawnedMonster.GetComponent<Monster>().speed = Random.Range(4, 10);
            }
            else

                spawnedMonster.GetComponent<Monster>().speed = -Random.Range(4, 10);
                spawnedMonster.transform.localScale = new Vector3(-1f, 1f, 1f);
