为什么所有的速度值都是0？

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

public class Spin : MonoBehaviour
{
    public GameObject prefabToRotate;
    [Range(1, 100)]
    public int numberOfObjects = 5;
    [Range(1, 500)]
    public float[] speeds;
    public bool randomNumbersOfObjects = false;
    public bool randomSpeed = false;

    private List<GameObject> instantiatedObjects = new List<GameObject>();

    // Start is called before the first frame update
    void Start()
    {
        speeds = new float[numberOfObjects];
        if(randomNumbersOfObjects == true)
        {
            numberOfObjects = Random.Range(1, 100);
        }
        if(randomSpeed == true)
        {
            for(int i = 0; i < speeds.Length; i++)
            {
                speeds[i] = Random.Range(1, 500);
            }
        }
        for(int i = 0; i < numberOfObjects; i++)
        {
            GameObject go = Instantiate(prefabToRotate);
            instantiatedObjects.Add(go);
        }
    }

    // Update is called once per frame
    void Update()
    {
        for (int i = 0; i < numberOfObjects; i++)
        {
            instantiatedObjects[i].transform.Rotate(Vector3.down, speeds[i] * Time.deltaTime);
        }
    }
}

以及如何从范围滑块中获取随机数和随机速度？1, 100 和 1, 500 ? 我还希望能够在更新中更改滑块的这个值，它会在运行游戏时实时更新对象的数量和随机速度。
