我使用Unity的JSON序列化在Unity中创建一个简单的保存游戏系统。我的保存游戏非常简单,我只保存角色的位置并加载它。在Unity中使用JSON保存游戏
保存游戏在游戏中正常工作。当我启动游戏并点击“保存”时,游戏将被保存,并且JSON文件将随我的玩家位置而更新。当我点击“加载”时,游戏加载正常,我的玩家被移到先前保存的位置。
然而,我的问题是,每当我关闭游戏并重新启动游戏时,'加载'功能只会将我的角色重置为我在其中生成的位置。它不会在我以前保存的最后一场比赛中的位置加载角色。
现在为我的代码。我有抱我的演员的数据的演员类:
using UnityEngine;
using System.Collections;
using System;
public class Actor : MonoBehaviour
{
public ActorData data = new ActorData(); // to store our data
public void StoreData() // for storing our data
{
data.pos = transform.position;
}
public void LoadData() // for loadinjg our data
{
transform.position = data.pos;
}
public void ApplyData()
{
SaveData.AddActorData(data);
}
void OnEnable() // to enable the save/load to avoid hanging
{
SaveData.OnLoaded += LoadData;
SaveData.OnBeforeSave += StoreData;
SaveData.OnBeforeSave += ApplyData;
}
void OnDisable() // to disable the save/load to avoid hanging
{
SaveData.OnLoaded -= LoadData;
SaveData.OnBeforeSave -= StoreData;
SaveData.OnBeforeSave -= ApplyData;
}
}
[Serializable] // for storing in JSON
public class ActorData // our players attributes in JSON
{
public Vector3 pos;
}
我也有一个ActorContainer来保存数据,不同的玩家:
using System.Collections.Generic;
using System;
[Serializable]
public class ActorContainer
{
// To store our different actors data
public List<ActorData> actors = new List<ActorData>();
}
我执行我的序列化一个保存数据类:
using UnityEngine;
using System.Collections;
using System.IO;
public class SaveData
{
// every actos will be sorted in this actor container when loading the game
public static ActorContainer actorContainer = new ActorContainer(); // static so that we dont have to recreacte savedata everytime
public delegate void SerializeAction();
public static event SerializeAction OnLoaded; // happens after loading
public static event SerializeAction OnBeforeSave; // right before saving
public static void Load(string path) // where the load is
{
actorContainer = LoadActors(path);
OnLoaded();
ClearActorList(); // so that there's no duplicates
}
public static void Save(string path, ActorContainer actors)
{
OnBeforeSave(); // to throw of the data that was in OnBeforeSave
SaveActors(path, actors); // store all of our actors as json in the file
ClearActorList(); // clear the list so that the next time we save theres no duplicates
}
public static void AddActorData(ActorData data)
{
actorContainer.actors.Add(data);
}
public static void ClearActorList() // to avoid duplicate data
{
actorContainer.actors.Clear(); // access actors and clear it
}
private static ActorContainer LoadActors(string path) // path to the JSON
{
string json = File.ReadAllText(path); // loading all the text out of the file into a string, assuming the text is all JSON
return JsonUtility.FromJson<ActorContainer>(json); // parse the JSON into an ActorContainer type and return in the LoadActors
}
private static void SaveActors(string path, ActorContainer actors) // where to save and the actors to save
{
string json = JsonUtility.ToJson(actors);
StreamWriter sw = File.CreateText(path); // if file doesnt exist, make the file in the specified path
sw.Close();
File.WriteAllText(path, json); // fill the file with the data(json)
}
}
最后我有一个GameController类,用作使用Unity沟通:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using System.IO;
public class GameController : MonoBehaviour
{ // to tell unity what it has to do, a communicator to be used with unity
// trigger buttons
public Button saveButton;
public Button loadButton;
private static string dataPath = string.Empty;
void Awake()
{
dataPath = System.IO.Path.Combine(Application.persistentDataPath, "actors.json"); // persistentDataPath unity save game path, actors.json name of the file containing actors
}
// for button
public void Save()
{
SaveData.Save(dataPath, SaveData.actorContainer);
}
// for button
public void Load()
{
SaveData.Load(dataPath);
}
}
我的JSON文件actors.json包含以下内容:
{ “演员”:[{ “POS”:{ “×”:419.6240539550781, “Y”:5.0189208984375, “Z”:0.0} }]}
欢迎任何建议。
你从来没有加载的值赋给''中Actor.cs' data.pos'。 – Smartis
