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。
