Saving the names of objects in a List to an external file
Hello! I am building an app that lets a user dynamically add and remove gameobjects from a scene. The gameobjects are currently being saved to a public List named furniture. I am wanting to allow users to save the names of the gameobjects within furniture to an external file, such as XML, CSV or JSON. I have been experimenting with JsonUtility.ToJson(this) and Sinbad.CsvUtil.SaveObjects but I'm struggling to get this to work.
Here is my current code:
void pickingListTaskOnClick ()
{
foreach (GameObject go in furniture)
{
furnitureNames.Add (go.name);
Debug.Log(go.name);
}
SaveToString ();
//Sinbad.CsvUtil.SaveObjects (furnitureNames, "pickingList.csv");
}
public string SaveToString ()
{
return JsonUtility.ToJson (furnitureNames);
}
To potentially add complications, the user will be running IOS or Android as this is a mobile app.
Any help would be appreciated, thanks!
Hi @danbrownemotivevm
As @ajaykewat said, you need a class in which your data will be stored.
Create a new C# script. Let's say DataManager.cs
And inside this script create another class that will serializae your data
Here is an example (not tested):
public class DataManager : MonoBehaviour
{
public static DataManager i;
private void Awake()
{
if (i != null)
{
Destroy(gameObject);
}
else
{
i = this;
DontDestroyOnLoad(gameObject);
}
Load();
}
public void Load()
{
DataModel.Load();
}
void OnApplicationPause(bool pauseStatus)
{
if(pauseStatus) {
DataModel.Save();
}
}
public void OnApplicationQuit()
{
DataModel.Save();
}
public void Trigger_ButtonSave()
{
DataModel.Save();
}
public DataModel DataModel = new DataModel("save");
}
[System.Serializable]
public class DataModel
{
public List<string> furnitureNames;
private string name;
public DataModel(string _name)
{
this.name = _name;
}
public void Save()
{
string json = JsonUtility.ToJson(this);
System.IO.File.WriteAllText(System.IO.Path.Combine(Application.persistentDataPath, "save.json"), json);
}
public void Load()
{
string jsonToFile = System.IO.File.ReadAllText(System.IO.Path.Combine(path, "save.json"));
DataModel packedData = JsonUtility.FromJson<DataModel>(jsonToFile);
this.furnitureNames= packedData.furnitureNames;
}
public void SetFurniture(string newFurniture)
{
furnitureNames.Add(newFurniture);
}
public void GetFurniture(int i)
{
return furnitureNames[i];
}
}
Hi @danbrownemotivevm , First of all you need a class in which your data should be store and then pass this class object to JsonUtility.ToJson method so after that you can save your data into json file.
