c# - Unity3d - C# - 如何备份数组的值？

Question

我在脚本 (C#) 中定义了一个包含 67 个元素的数组。每个元素都是我定义的包含一些变量的类的对象。像下面这样:

// the Definition of the array
public Pack[] packsInfo;

// the class 
[Serializable]
public class Pack
{
    public int number;
    public int angle;
    public float zPosition;
    public float beatCaseDistance;
    public float gunDistance;
}

然后，我在 Inspector 中分​​配所有值。像下面这样:

所以...如果我突然更改任何值或什至更糟(这些值由于任何原因而消失。例如更改类参数或任何其他内容)，那么我必须花费数小时来设置所有值。所以我想打印文本或文件中的所有值并保存它们。以便稍后恢复它们。我想要一个备份解决方案。我想用编程来做。 (我不想手动编写它们；)。这是浪费时间。 )

要保存您的数组，您可以使用例如 JsonUtillity .

很简单!祝你好运!

 void Start () {
    /////////////////////// save to json
    JSONObject jsonSave = new JSONObject();
    for(int i=0; i < packsInfo.Length; i++) {
        JSONObject packJson = new JSONObject();
        packJson.AddField("number", packsInfo[i].number);
        packJson.AddField("angle", packsInfo[i].angle);
        packJson.AddField("z_position", packsInfo[i].zPosition);
        packJson.AddField("beat_case_distance", packsInfo[i].beatCaseDistance);
        packJson.AddField("gun_distance", packsInfo[i].gunDistance);
        jsonSave.Add(packJson);
    }

    System.IO.StreamWriter streamWritter = new System.IO.StreamWriter(@"C:\MyGameFiles\packs.json");
    streamWritter.WriteLine(jsonSave.Print(true));
    streamWritter.Close();
    streamWritter = null;
    /////////////////////// read json
    System.IO.StreamReader reader = new System.IO.StreamReader(@"C:\MyGameFiles\packs.json");
    string jsonString = reader.ReadToEnd();
    reader.Close();
    reader = null;

    JSONObject jsonRead = new JSONObject(jsonString);
    packsInfo = new Pack[jsonRead.Count];
    for(int i =0; i < jsonRead.Count; i ++) {
        Pack pack = new Pack();
        pack.number = (int)jsonRead[i]["number"].i;
        pack.angle = (int)jsonRead[i]["angle"].i;
        pack.zPosition = jsonRead[i]["z_position"].f;
        pack.beatCaseDistance =jsonRead[i]["beat_case_distance"].f;
        pack.gunDistance = jsonRead[i]["gun_distance"].f;
        packsInfo[i] = pack;
    }
}
