从脚本Unity3d C#中销毁由脚本创建的对象

向下运行好吧，伙计们和女孩们需要一点帮助。基本上，我是从打开位置的预制件实例化healthPack。经过一段时间后，如果HealthPack没有被提取，我将尝试销毁它，将bool healthPackExist设置回false，并在空闲位置实例化另一个HealthPack。

问题：当我试图访问正在实例化的gameObject时，我最终要么破坏整个父层次结构，要么只是删除脚本。

解决方案我尝试过破坏根对象，搜索创建的对象的名称，向对象添加标记(健康包(，搜索它总是出错。

代码如下：

public GameObject healthPackPrefab;
public GameObject health;
private float healthTimer;
private bool healthExist;
// Use this for initialization
void Start () 
{
    //set healthExist to false to indicate no health packs exist on game start
    healthExist = false;
}
// Update is called once per frame
void Update () 
{
    //first check to see if a health pack exist, if not call method to spawn a health pack
    //otherwise check to see if one exist and if it does is it's timer created with it
    //has been passed by Time.time (returns game clock time), if yes destroy the created
    //health pack.
    if (healthExist == false) 
    {
        spawnUntilFull ();
    } 
    else if (healthExist == true && Time.time > healthTimer)
    {
        //Error occuring here when trying to destroy
        //Destroy(transform.root.gameObject)    //destroys script, object scripts on, and prefab
        Destroy(this.gameObject);   //does same as Destroy(transform.root.gameObject
        healthExist = false;
    }
}

Transform NextFreePosition()
{
    //free space
    foreach (Transform childPositionGameObject in transform) 
    {
        //if no health packs located return location of child object to spawn new health pack
        if (childPositionGameObject.childCount == 0) 
        {
            return childPositionGameObject;
        }
    }
    return null;
}
void spawnUntilFull()
{
    //returns next free position in space
    Transform freePosition = NextFreePosition ();
    //if free slot is available
    if (freePosition && healthExist == false) 
    {
        //instantiates health object and places it in scene at coordinates received from
        //freePosition
        health = Instantiate (healthPackPrefab, freePosition.position, Quaternion.identity) as GameObject;
        //spawns enemy onto a position under the Parent (Enemy Formation)
        health.transform.parent = freePosition;
        //set bool to true to stop spawning
        healthExist = true;
        //seat HealthTimer to 5 seconds after creation for use in Update method
        healthTimer = Time.time + 5.0f;
    }
}

Destroy(health);

Destroy(GameObject object, float delay);
