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。
