如何解决我想在Unity中从一个脚本访问另一个脚本的公共方法我已经尝试了以下代码

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

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;
        }
    }
}

Player.cs脚本

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;
    }
}

解决方法

我多次阅读了代码，终于意识到您的答案已经对您的问题是正确的：

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

我在您的代码中对此进行了验证，即使没有这样的函数，您实际上也调用了函数ObjectPoolingManager.Instance.GetBullet()，而实际上应该是GetBulltet()的函数GetBullet()。
