【问题描述】：

从ObjectPoolingManager.cs 中的公共GameObject GetBulltet () 访问Player.cs 中的ObjectPoolingManager.Instance.GetBullet(); 时出现以下错误

Assets\SPF_Assets\Scripts\Game\Player.cs(4,7): error CS0138: A 'using namespace' directive can only be applied to namespaces; 'ObjectPoolingManager' is a type not a namespace. Consider a 'using static' directive instead

Player.cs 脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using ObjectPoolingManager; //Tried this, didnt work

public class Player : MonoBehaviour
{
    public Camera playerCamera;
    public GameObject bulletPrefab;
    // Update is called once per frame
    void Update() {
        if(Input.GetMouseButtonDown(0)){
            ObjectPoolingManager.Instance.GetBullet();

            GameObject bulletObject = Instantiate (bulletPrefab);
            bulletObject.transform.position = playerCamera.transform.position + playerCamera.transform.forward;
            bulletObject.transform.forward = playerCamera.transform.forward;
        }
    }
}

ObjectPoolingManager.cs

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

public class ObjectPoolingManager : MonoBehaviour {

    private static ObjectPoolingManager instance;
    public static ObjectPoolingManager Instance { get { return instance; } }

    // Start is called before the first frame update
    void Awake () {
        instance = this;
    }

    public GameObject GetBulltet () {
        Debug.Log ("Hell0");
        return null;
    }
}

【问题讨论】：

删除此行using ObjectPoolingManager; //Tried this, didnt work
也试过了，还是不行。评论说。
如果该行真的被删除了，至少应该修改错误信息，因为Player.cs的第4行现在是空的。
我删除了那一行，现在是这个：Assets\SPF_Assets\Scripts\Game\Player.cs(12,43): error CS1061: 'ObjectPoolingManager' does not contain a definition for 'GetBullet' and没有可访问的扩展方法“GetBullet”接受“ObjectPoolingManager”类型的第一个参数
我认为这是一个错字，因为方法名称是GetBulltet

【解决方案1】：

我多次重新阅读代码，终于意识到你的答案已经在你的问题中了：

I am getting the below error while accessing
ObjectPoolingManager.Instance.GetBullet(); in Player.cs
from public GameObject GetBulltet () which is in ObjectPoolingManager.cs

我在你的代码中验证了这一点，你实际上调用了一个函数 ObjectPoolingManager.Instance.GetBullet()，即使没有这样的函数，而是 GetBulltet()，它应该是 GetBullet()。
