如何管理 save/load 的数百个变量

Question

我正在 Unity 中制作角色扮演游戏。仍然很新，所以我遵循了 their 创建 save/load 功能的教程。

在本教程中，他们使用了 2 个变量，并且效果很好。但是我想创建一个带有沙盒的大型游戏。这意味着我需要保存所有东西在我的世界中的位置，除此之外我还需要很多玩家统计数据、可解锁项、任务、NPC 进度等等。

到目前为止，我有一个 saving/loading 我的球员初始统计数据的有效实施，仅此一项就产生了很多：

DataManager

public class DataManager : MonoBehaviour {

    private string saveLocation = "/data.dat";

    public static DataManager manager;

    //PLAYER
    public int maxHealth;
    public int currentHealth;
    public int currentLevel;
    public int currentExp;
    public int [] toLevelUp;

    void Awake(){
        if (manager == null) {
            DontDestroyOnLoad (gameObject);
            manager = this;
        } else if (manager != this) {
            Destroy (gameObject);
        }
    }


    public void Save(){
        Debug.Log ("Saving");
        BinaryFormatter bf = new BinaryFormatter ();
        FileStream file = File.Create (Application.persistentDataPath + saveLocation);

        PlayerData playerData = new PlayerData (maxHealth, currentHealth, currentLevel, currentExp, toLevelUp);

        bf.Serialize (file, playerData);
        file.Close ();
    }

    public void Load(){
        Debug.Log ("Loading");
        if (File.Exists (Application.persistentDataPath + saveLocation)) {
            BinaryFormatter bf = new BinaryFormatter ();
            FileStream file = File.Open (Application.persistentDataPath + saveLocation, FileMode.Open);

            PlayerData playerData = (PlayerData)bf.Deserialize (file);
            file.Close ();

            maxHealth = playerData.maxHealth;
            currentHealth = playerData.currentHealth;
            currentLevel = playerData.currentLevel;
            currentExp = playerData.currentExp;
            toLevelUp = playerData.toLevelUp;
        }
    }
}

玩家数据

[System.Serializable]
public class PlayerData {

    public int maxHealth;
    public int currentHealth;
    public int currentLevel;
    public int currentExp;
    public int [] toLevelUp;

    public PlayerData(int maxHealth, int currentHealth, int currentLevel, int currentExp, int [] toLevelUp){
        this.maxHealth = maxHealth;
        this.currentHealth = currentHealth;
        this.currentLevel = currentLevel;
        this.currentExp = currentExp;
        this.toLevelUp = toLevelUp;
    }

}

这根本就不是可扩展的。是否有人具有使用任何 advice/code 样本对大量变量实施 save/load 的经验？一定有更好的办法吧？

编辑：

新数据管理器：

public class DataManager : MonoBehaviour {

private string saveLocation = "/data.dat";

public static DataManager manager;

//PLAYER
public PlayerData playerData = new PlayerData ();

void Awake(){
    if (manager == null) {
        DontDestroyOnLoad (gameObject);
        manager = this;
    } else if (manager != this) {
        Destroy (gameObject);
    }

}


public void Save(){
    Debug.Log ("Saving");
    BinaryFormatter bf = new BinaryFormatter ();
    FileStream file = File.Create (Application.persistentDataPath + saveLocation);

    bf.Serialize (file, playerData);
    file.Close ();
}

public void Load(){
    Debug.Log ("Loading");
    if (File.Exists (Application.persistentDataPath + saveLocation)) {
        BinaryFormatter bf = new BinaryFormatter ();
        FileStream file = File.Open (Application.persistentDataPath + saveLocation, FileMode.Open);

        PlayerData pd = (PlayerData)bf.Deserialize (file);
        file.Close ();

        playerData = pd;
    }
}

}

Answer 1

您不必每次都创建新的 PlayerData 来保存它。您不必像在构造函数中那样复制它。创建一个 PlayerData 实例，然后在您的游戏中使用它。就是这样。删除那些局部变量，因为它们已经在 PlayerData class 中。

不要这样做：

[System.Serializable]
public class PlayerData
{

    public int maxHealth;
    public int currentHealth;
    public int currentLevel;
    public int currentExp;
    public int[] toLevelUp;
}

//Why Why would you need these again?
public int maxHealth;
public int currentHealth;
public int currentLevel;
public int currentExp;
public int[] toLevelUp;

private string saveLocation = "/data.dat";

//PLAYER
public PlayerData playerData = new PlayerData();

public void Save()
{
    if (File.Exists(Application.persistentDataPath + saveLocation))
    {
        BinaryFormatter bf = new BinaryFormatter();
        FileStream file = File.Open(Application.persistentDataPath + saveLocation, FileMode.Open);

        PlayerData playerData = (PlayerData)bf.Deserialize(file);
        file.Close();

        //Whyyyyyyyyyyyy Don't do this
        maxHealth = playerData.maxHealth;
        currentHealth = playerData.currentHealth;
        currentLevel = playerData.currentLevel;
        currentExp = playerData.currentExp;
        toLevelUp = playerData.toLevelUp;
    }
}

请注意您是如何重新定义 maxHealth、currentHealth、currentLevel、currentExp 和 toLevelUp 变量的。完全没有必要。

这样做：

[System.Serializable]
public class PlayerData
{

    public int maxHealth;
    public int currentHealth;
    public int currentLevel;
    public int currentExp;
    public int[] toLevelUp;
}

string saveLocation = "/data.dat";

//Make the PlayerData data part of your game
PlayerData playerData;

void Start()
{

    playerData = new PlayerData();
    playerData.maxHealth = 100;
    playerData.currentLevel = 1;
    playerData.currentHealth = 50;
}

public void Save(PlayerData pData)
{
    UnityEngine.Debug.Log("Saving");
    BinaryFormatter bf = new BinaryFormatter();
    FileStream file = File.Create(Application.persistentDataPath + saveLocation);
    bf.Serialize(file, pData);
    file.Close();
}

想保存的时候调用Save(playerData);即可。

注意如何不需要复制数据或执行 PlayerData playerData = new PlayerData (maxHealth, currentHealth, currentLevel, currentExp, toLevelUp);。只需保存您已经在游戏中使用的实例。

最后，使用，您可以在一行中完成此操作 DataSaver.saveData(playerData, "players");
