c# - Random.Range(float, float) 无法通过实例引用访问；用类型名称来限定它

Question

每当我尝试在两个参数之间生成随机数时，都会出现错误:

Random.Range(float, float) 无法通过实例引用访问；使用类型名称来限定它

我是 Unity 新手，因此我们将不胜感激。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Spawner : MonoBehaviour
{
    public GameObject enemy;
    float randx;
    float randy;
    Vector2 whereToSpawn;
    public float spawnRate = 2f;
    float nextSpawn = 0f;
    Random random = new Random();
    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        if(Time.time > nextSpawn)
        {
            nextSpawn = Time.time + spawnRate;
            randx = random.Range(-1.408f, 1.232f);
            randy = random.Range(0.776f, 1.232f);
            whereToSpawn = new Vector2 (randx, randy);
            Instantiate(enemy, whereToSpawn, Quaternion.identity);
        }
    }
}

Range 不是实例方法，必须通过其类型访问它。替换这个:

randx = random.Range(-1.408f, 1.232f);
randy = random.Range(0.776f, 1.232f);

这样:

randx = Random.Range(-1.408f, 1.232f);
randy = Random.Range(0.776f, 1.232f);
