错误 CS0103：名称"playfabManager"在当前上下文中不存在

Question

我刚开始使用Unity制作一个名为flappy duck的小游戏。我想有一个在线排行榜，这样每个人都可以以高分击败对方。我偶然发现了这个错误Assets\scripts\PlayerController.cs(65,9(：错误CS0103:名称"playfabManager"在当前上下文中不存在

我找不出什么毛病。顺便说一句，我正在使用教程来自CoCo代码https://www.youtube.com/watch?v=e2RXDso6fWU&t=266他使用playfab我正在努力让它在我自己的游戏中发挥作用。这是使文本显示高核心的脚本

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class HighSScore : MonoBehaviour
{
public Text HighScore;
// Start is called before the first frame update
void Start()
{
HighScore.text = PlayerPrefs.GetInt("highscore").ToString();
}
}

我是PLAYFAB经理

using System.Collections.Generic;
using UnityEngine;
using PlayFab;
using PlayFab.ClientModels;
public class PlayFabManager : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
Login();   
}
void Login()
{
var request = new LoginWithCustomIDRequest
{
CustomId = SystemInfo.deviceUniqueIdentifier,
CreateAccount = true
};
PlayFabClientAPI.LoginWithCustomID(request, OnSuccess, OnError);
}

void OnSuccess(LoginResult result)
{
Debug.Log("Successful login/account create!");
}
void OnError(PlayFabError error)
{
Debug.Log("Error while logging in/creating account!");
Debug.Log(error.GenerateErrorReport());
}
public void SendLeaderboard(int score)  
{
var request = new UpdatePlayerStatisticsRequest
{
Statistics = new List<StatisticUpdate>
{
new StatisticUpdate
{
StatisticName = "score",
Value = score
}
}
};
PlayFabClientAPI.UpdatePlayerStatistics(request, OnLeaderboardUpdate, OnError);
}
void OnLeaderboardUpdate(UpdatePlayerStatisticsResult result)
{
Debug.Log("succsessfull send leaderboard");
}
}`

最后这是游戏控制器吗如果错误是基于第65行我正试着把高分送上playfab的排行榜。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
using UnityEngine.SceneManagement;
using UnityEngine.UI;
public class PlayerController : MonoBehaviour
{
[SerializeField] TextMeshProUGUI scoreText;
Rigidbody2D bird;
int score = 0;
bool dead = false;
int highscore = 0;

// Start is called before the first frame update
void Start()
{
bird = transform.GetComponent<Rigidbody2D>();
}
// Update is called once per frame
public void update ()
{
if (Input.GetKeyDown("space") && !dead)
{
bird.velocity = new Vector2(0, 6f);
}
if (Input.GetKeyDown("r"))
{
SceneManager.LoadSceneAsync(SceneManager.GetActiveScene().buildIndex);
}
if (score > highscore)
{
highscore = score;
SendLeaderboard();
PlayerPrefs.SetInt("highscore", score);
}
}
void OnCollisionEnter2D()
{
dead = true;
score = 0;
scoreText.text = "0";
}
void OnTriggerExit2D(Collider2D col)
{
if (col.gameObject.tag == "PointTrigger")
{
score++;
scoreText.text = score.ToString();
}
}
void OnTriggerExit(Collider col)
{
if (col.gameObject.tag == "PointTrigger")
{
score++;
scoreText.text = score.ToString();
}
}
public void SendLeaderboard()
{
playfabManager.SendLeaderboard(highscore);
}
}

我希望有人能帮助我。

很可能在PlayerController中您想要一个

[SerializeField] private PlayFabManager playfabManager;

并通过检查器或在运行时通过例如引用它

private void Awake ()
{
// Try and get the component if it is attached to the same object as this
if(! playfabManager) playfabManager = GetComponent<PlayFabManager>();
// Or try and find it anywhere in the scene
if(! playfabManager) playfabManager = FindObjectOfType<PlayFabManager>();
// Or simply create and attach it to the same object as this one
if(! playfabManager) playfabManager = gameObject.AddComponent<PlayFabManager>();
}

或者——在我看来，这将是更正确的解决方案——PlayerFabManager应该而不是是MonoBehaviour，而是简单地进行

public class PlayFabManager
{
public void Login()
{
...  
}
...
}

在PlayerController中，您更愿意进行

private readonly PlayFabManager playfabManager = new PlayFabManager();
private void Start ()
{
playfabManager.Login();
}
