所以我为我的游戏做了一个产卵系统，我有两个列表，敌人和产卵点。奇怪的是，当我引用enemiedata来获取产卵之间的时间时，它给了我这个错误
参数异常：GetComponent要求请求的组件"EnemieData"派生自MonoBehaviour或Component或者是接口。
（enemiedata是可编写脚本的对象）
下面是我的代码：

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

public class EnemieSpawn : MonoBehaviour
{
    //If your game is not Procedurally Generated just drag and drop your spawn points onto this list.
    public List<Transform> spawnPoints;
    public List<GameObject> enemies;
    public bool spawn;
    public float timeSinceLastSpawn;

    public void Update()
    {
        timeSinceLastSpawn += Time.deltaTime;

        if (spawn == true)
        {
            foreach(GameObject enemie in enemies)
            {
                foreach (Transform spawn in spawnPoints)
                {
                    EnemieData enemiedata = enemie.GetComponent<EnemieData>();

                    if (enemiedata.spawnrate >= timeSinceLastSpawn)
                    {
                        SpawnEnemy(spawn, enemie);
                    }
                }

                timeSinceLastSpawn = 0;
            }
        }
    }

    //Method to spawn your enemy at a given point.
    public void SpawnEnemy(Transform spawnPoint, GameObject enemies)
    {
        Instantiate(enemies, spawnPoint.position, spawnPoint.rotation);
    }
}
