Unity序列化与反序列化怎么实现

在Unity中，序列化和反序列化是通过Unity自带的JsonUtility类来实现的。JsonUtility类提供了静态方法ToJson和FromJson，分别用于将对象序列化为JSON字符串和将JSON字符串反序列化为对象。

序列化示例代码：

using UnityEngine;

[System.Serializable]
public class PlayerData
{
    public string playerName;
    public int playerLevel;
    public float playerHealth;
}

public class SerializationExample : MonoBehaviour
{
    void Start()
    {
        PlayerData player = new PlayerData();
        player.playerName = "Player1";
        player.playerLevel = 1;
        player.playerHealth = 100f;

        string json = JsonUtility.ToJson(player);
        Debug.Log(json);
    }
}

反序列化示例代码：

using UnityEngine;

[System.Serializable]
public class PlayerData
{
    public string playerName;
    public int playerLevel;
    public float playerHealth;
}

public class DeserializationExample : MonoBehaviour
{
    void Start()
    {
        string json = "{\"playerName\":\"Player1\",\"playerLevel\":1,\"playerHealth\":100}";
        PlayerData player = JsonUtility.FromJson<PlayerData>(json);

        Debug.Log("Player Name: " + player.playerName);
        Debug.Log("Player Level: " + player.playerLevel);
        Debug.Log("Player Health: " + player.playerHealth);
    }
}

在上面的示例中，我们定义了一个PlayerData类来存储玩家的数据，然后通过JsonUtility.ToJson方法将PlayerData对象序列化为JSON字符串，再通过JsonUtility.FromJson方法将JSON字符串反序列化为PlayerData对象。最后我们可以通过访问PlayerData对象的属性来获取反序列化后的数据。
