Unity如何在随机小数位置生成预制件？

using UnityEngine;

public class SpawnPrefab : MonoBehaviour
{
    public GameObject prefab; // 预制件

    void Start()
    {
        // 生成10个预制件
        for (int i = 0; i < 10; i++)
        {
            // 生成随机位置
            float randomX = Random.Range(-10f, 10f);
            float randomY = Random.Range(-5f, 5f);
            float randomZ = Random.Range(-10f, 10f);
            Vector3 randomPosition = new Vector3(randomX, randomY, randomZ);

            // 实例化预制件并设置位置
            GameObject spawnedPrefab = Instantiate(prefab, randomPosition, Quaternion.identity);

            // 设置父对象
            spawnedPrefab.transform.SetParent(transform);
        }
    }
}
