1.在指定位置生成物体，将生成的物体直接作为指定父级的子级

代码实现：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
/// <summary>
/// 挂载到父物体上   动态生成物体
/// </summary>
public class SpawnManager : MonoBehaviour
{// 在Inspector中指定生成位置的参考对象public Transform spawnReference;// 在Inspector中指定生成的物体类型public GameObject[] spawnPrefabs;// 在Inspector中指定生成间隔时间public float spawnInterval = 1.0f;// 在Inspector中指定父级对象public Transform parentTransform;// 用于存储生成的物体，以便后续管理//public GameObject[] spawnedObjects;//private int currentIndex = 0;// Start is called before the first frame updatevoid Start(){// 初始化数组，假设最多生成10个物体//spawnedObjects = new GameObject[10];// 开始生成物体InvokeRepeating("SpawnObject", 0.0f, spawnInterval);}void SpawnObject(){如果数组已满，停止生成//if (currentIndex >= spawnedObjects.Length)//{//    Debug.Log("Reached maximum number of spawned objects.");//    ClearSpawnedObjects();//    return;//}// 随机选择一个预制体int prefabIndex = Random.Range(0, spawnPrefabs.Length);GameObject prefabToSpawn = spawnPrefabs[prefabIndex];// 获取生成位置Vector3 spawnPosition = spawnReference != null ? spawnReference.position : Vector3.zero;// 实例化物体，并将其设置为指定父级的子级GameObject spawnedObject = Instantiate(prefabToSpawn, spawnPosition, Quaternion.identity, parentTransform);MoveObject moveobject = spawnedObject.GetComponent<MoveObject>();if (moveobject != null){// 成功获取脚本  设置存活时间moveobject.SetLifetime(3f);}else{Debug.LogError("未找到目标脚本");}将生成的物体存储在数组中//spawnedObjects[currentIndex] = spawnedObject;增加索引//currentIndex++;}提供一个方法来清理生成的物体//public void ClearSpawnedObjects()//{//    for (int i = 0; i < currentIndex; i++)//    {//        if (spawnedObjects[i] != null)//        {//            Destroy(spawnedObjects[i]);//        }//    } //    // 初始化数组，假设最多生成10个物体//    spawnedObjects = new GameObject[10];//    // 重置索引//    currentIndex = 0;//}
}

2.在指定范围内，随机生成物体

代码实现：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
/// <summary>
/// 挂载到父物体上   动态随机位置生成物体
/// </summary>
public class RandomSpawner : MonoBehaviour
{// 在Inspector中指定生成位置的参考对象public Transform spawnReference;// 在Inspector中指定生成的物体类型public GameObject[] spawnPrefabs;// 在Inspector中指定生成间隔时间public float spawnInterval = 1.0f;// 在Inspector中指定父级对象public Transform parentTransform;// 在Inspector中指定随机生成范围public Vector2 spawnArea = new Vector2(10f, 10f);void Start(){// 检查是否有可生成的预制体if (spawnPrefabs == null || spawnPrefabs.Length == 0){Debug.LogError("未指定生成的预制体！");return;}// 开始生成物体InvokeRepeating("SpawnObject", 0.0f, spawnInterval);}void SpawnObject(){// 随机选择一个预制体int prefabIndex = Random.Range(0, spawnPrefabs.Length);GameObject prefabToSpawn = spawnPrefabs[prefabIndex];// 获取生成位置Vector3 spawnPosition = GetRandomSpawnPosition();// 实例化物体，并将其设置为指定父级的子级GameObject spawnedObject = Instantiate(prefabToSpawn, spawnPosition, Quaternion.identity, parentTransform);// 设置物体的存活时间 10秒SetObjectLifetime(spawnedObject, 10f);}Vector3 GetRandomSpawnPosition(){// 如果指定了参考对象，则以参考对象的位置为中心生成Vector3 center = spawnReference != null ? spawnReference.position : Vector3.zero;// 在指定范围内随机生成位置float randomX = Random.Range(-spawnArea.x / 2, spawnArea.x / 2);float randomZ = Random.Range(-spawnArea.y / 2, spawnArea.y / 2);return center + new Vector3(randomX, 0, randomZ);}void SetObjectLifetime(GameObject obj, float lifetime){MoveObject moveObject = obj.GetComponent<MoveObject>();if (moveObject != null){// 成功获取脚本，设置存活时间moveObject.SetLifetime(lifetime);}else{Debug.LogError("未找到目标脚本：MoveObject");}}
}
