Question

我有一个脚本不会自动保存高分，并且在我按下重新启动按钮之前，我的高分已保存，没有任何代码。我希望即使玩家重启游戏也可以保存高分。这是我的SCORE代码：

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

public class Score : MonoBehaviour
{
    public int score;
    public Text ScoreText;
    public int highscore;
    public Text highScoreText;


    void Start()
    {
        highscore = PlayerPrefs.GetInt("HighScore: " + highscore);
    }

    void Update()
    {
        ScoreText.text = "Score: " + score;
        highScoreText.text = highscore.ToString();
        if (score > highscore)
        {
            highscore = score;

            PlayerPrefs.SetInt("HighScore: ", highscore);
        }
    }
    void OnTriggerEnter(Collider other)
    {
        Debug.Log("collider is working");
        if (other.gameObject.tag == "Score: ")
        {
            score++;
        }
    }
}

这是重新启动按钮的代码：

using UnityEngine;
using UnityEngine.SceneManagement;
using System.Collections;

public class RestartGame : MonoBehaviour
{
    public void RestartsGame()
    {
        SceneManager.LoadScene(SceneManager.GetActiveScene().name); // loads current scene
    }
}

Answer 1

您对PlayerPrefs使用的键有疑问：

void Start()
{
    highscore = PlayerPrefs.GetInt("HighScore");
}

void Update()
{
    ScoreText.text = "Score: " + score;
    highScoreText.text = highscore.ToString();
    if (score > highscore)
    {
        highscore = score;

        PlayerPrefs.SetInt("HighScore", highscore);

    }
}

Draco18s指出

您不应使用玩家偏好来保存游戏数据（例如高分）。

如果需要，可以在这里将其保存在json文件中。如果您想添加诸如前10名得分之类的东西，它还增加了灵活性。

using UnityEngine;
using System.IO;

public class HighestScoreJson
{
    /// <summary>
    /// //Returns the path to the highestScoreFile
    /// </summary>
    /// <returns></returns>
    public static string GetPathToHighestScore() {
        return Path.Combine(Application.persistentDataPath, "HighestScore.json"); //You can look for info about the unity streamingAssets folder in the unity documentation
    }

    /// <summary>
    /// Get the highestScore
    /// </summary>
    /// <returns></returns>
    public static HighestScore GetHighestScore() {
        string path = GetPathToHighestScore();

        if (!File.Exists(path)) //Checks if the file exists
        {
            HighestScore highestScore = new HighestScore();
            string jsonObj = JsonUtility.ToJson(highestScore);
            //Debug.Log("SavedJsonFile: " + jsonObj);
            FileInfo defaultFile = new FileInfo(path);
            defaultFile.Directory.Create(); // If the directory already exists, this method does nothing.
            File.WriteAllText(path, jsonObj);
        }

        string file = File.ReadAllText(path);
        HighestScore highestScoreJson = JsonUtility.FromJson<HighestScore>(file);
        //Debug.Log(highestScoreJson.highestScore); //here you can check the value on the debug if you want
        return highestScoreJson;
    }

    /// <summary>
    /// Save a new highestScore
    /// </summary>
    /// <param name="highestScore"></param>
    public static void SaveHighestScore(int highestScoreValue) {
    string path = GetPathToHighestScore();
    HighestScore highestScore = new HighestScore();
    highestScore.highestScore = highestScoreValue;
    string jsonObj = JsonUtility.ToJson(highestScore);
    //Debug.Log("SavedJsonFile: " + jsonObj);
    FileInfo file = new FileInfo(path);
    file.Directory.Create(); // If the directory already exists, this method does nothing.
    File.WriteAllText(path, jsonObj);
    }
}

/// <summary>
/// This class holds the highestScore
/// </summary>
public class HighestScore
{
    public int highestScore;
    //You can also create a list if you want with the top 10 or something like that
}

然后您将像这样使用它

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

public class Score : MonoBehaviour
{
    public int score;
    public Text ScoreText;
    public int highscore;
    public Text highScoreText;


    void Start()
    {               
        highscore = HighestScoreJson.GetHighestScore().highestScore; 
    }

    void Update()
    {
        ScoreText.text = "Score: " + score;
        highScoreText.text = highscore.ToString();
        if (score > highscore)
        {
            highscore = score;
        HighestScoreJson.SaveHighestScore(highscore);
        }
    }
    void OnTriggerEnter(Collider other)
    {
        Debug.Log("collider is working");
        if (other.gameObject.tag == "Score: ")
        {
            score++;
        }
    }

}

如果您进行了更新，并且仅在乐谱变化时调用更改文本，您可能可以优化您的通话。

void Update() //Don't need it
{
}
void OnTriggerEnter(Collider other)
{
    Debug.Log("collider is working");
    if (other.gameObject.tag == "Score: ")
    {
        score++;
        ScoreText.text = "Score: " + score;
        highScoreText.text = highscore.ToString();
        if (score > highscore)
        {
           highscore = score;
           HighestScoreJson.SaveHighestScore(highscore);
        }
    }
}
