            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);
        }
    }

如何从“范围”滑块获取随机数和随机速度？ 1，100和1，500？我还希望能够在“更新”中更改滑块的此值，并且它将在运行游戏时实时更新对象数量和随机速度。

Answer 1

将“速度”数组的长度设置为“ numberOfObjects”，然后更改“ numberOfObjects”的值，但“速度”数组仍等于“ numberOfObjects”的旧值。尝试在为'numberOfObjects'分配一个随机值之后，在中设置'speeds'的长度，

if (randomNumbersOfObjects == true)
{
    numberOfObjects = Random.Range(1, 100);
}
speeds = new float[numberOfObjects];

为什么所有速度值都为0？
