Hello!
im trying to save a objects pos before loading a other scene, and when you load the main scene again to load and add the saved pos for the object.
I have tried to add Application.LoadLevel(“MyScene”) but i dont know if it does save or load the pos right, it just change scenes and say “file writen” and “file read”
So my question is, where do i put the load code to properly save before load a new scene, and load pos after the main scene is loaded?
Here is the CSharp code for it.
using UnityEngine;
using System.Collections;
using System.Xml;
using System.Xml.Serialization;
using System.IO;
using System.Text;
public class SavingPosition: MonoBehaviour {
Rect _Save, _Load, _SaveMSG, _LoadMSG;
bool _ShouldSave, _ShouldLoad,_SwitchSave,_SwitchLoad;
string _FileLocation,_FileName;
public GameObject _Player;
UserData myData;
string _PlayerName;
string _data;
Vector3 VPosition;
void Start () {
_Save=new Rect(10,80,100,20);
_Load=new Rect(10,100,100,20);
_SaveMSG=new Rect(10,120,400,40);
_LoadMSG=new Rect(10,140,400,40);
_FileLocation=Application.dataPath;
_FileName="SaveData.xml";
_PlayerName = "Player";
myData=new UserData();
}
void Update () {}
void OnGUI()
{
if (GUI.Button(_Load,"Load")) {
GUI.Label(_LoadMSG,"Loading from: "+_FileLocation);
LoadXML();
if(_data.ToString() != "")
{
myData = (UserData)DeserializeObject(_data);
VPosition=new Vector3(myData._iUser.x,myData._iUser.y,myData._iUser.z);
_Player.transform.position=VPosition;
Debug.Log(myData._iUser.name);
}
}
if (GUI.Button(_Save,"Save")) {
GUI.Label(_SaveMSG,"Saving to: "+_FileLocation);
myData._iUser.x=_Player.transform.position.x;
myData._iUser.y=_Player.transform.position.y;
myData._iUser.z=_Player.transform.position.z;
myData._iUser.name=_PlayerName;
_data = SerializeObject(myData);
CreateXML();
Debug.Log(_data);
}
}
string UTF8ByteArrayToString(byte[] characters)
{
UTF8Encoding encoding = new UTF8Encoding();
string constructedString = encoding.GetString(characters);
return (constructedString);
}
byte[] StringToUTF8ByteArray(string pXmlString)
{
UTF8Encoding encoding = new UTF8Encoding();
byte[] byteArray = encoding.GetBytes(pXmlString);
return byteArray;
}
string SerializeObject(object pObject)
{
string XmlizedString = null;

return XmlizedString;
}
object DeserializeObject(string pXmlizedString)
{

XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);
return xs.Deserialize(memoryStream);
}
void CreateXML()
{
StreamWriter writer;
FileInfo t = new FileInfo(_FileLocation+"\\"+ _FileName);
if(!t.Exists)
{
writer = t.CreateText();
}
else
{
t.Delete();
writer = t.CreateText();
}
writer.Write(_data);
writer.Close();
Debug.Log("File written.");
}
void LoadXML()
{
StreamReader r = File.OpenText(_FileLocation+"\\"+ _FileName);
string _info = r.ReadToEnd();
r.Close();
_data=_info;
Debug.Log("File Read");
}
}
public class UserData
{
public DemoData _iUser;
public UserData() { }
public struct DemoData
{
public float x;
public float y;
public float z;
public string name;
}
}
and thats not how i want it to be
