retrieving a serialized Playerprefs specific value in Unity

I want to retrieve my integer value in my SaveState class which is already serialized as a string in Playerprefs and I want to access its values on my PlayerHealth and store it on a float variable. I'm just new in c# thanks for understanding I hope someone can help me in this.

SaveState

Playerprefs

PlayerHealth

This is my SaveState class:

SaveState

public class SaveState
public float FullHealth = 10; //The value that i Want
public float staminaPTS;



This is my PlayerHealth class:

PlayerHealth

public class PlayerHealth : MonoBehaviour
public SaveState stateREF;
float bulan_fullhp;
float bulan_fullsp;
float currHP;
float currSP;

//HUD Variables
public Slider healthSlider;

void Start ()
load ();
bulan_fullhp = // THIS IS WHERE I WANT TO REFERENCE THE SERIALIZED PLAYERPREF "FUllHealth" VALUE IN MY Save_State Class
currHP = bulan_fullhp;
currSP = bulan_fullsp;

//Hud Iniitialization
healthSlider.maxValue = bulan_fullhp;
healthSlider.value = bulan_fullhp;
Debug.Log (currHP);


public void save()
PlayerPrefs.SetString ("save", Helper.Serialize <SaveState> (stateREF));


public void load()
if (PlayerPrefs.HasKey ("save"))
stateREF = Helper.Deserialize<SaveState> (PlayerPrefs.GetString ("save"));
else

stateREF = new SaveState ();
save ();



public void addDamage(float damage)
if (damage <= 0)
return;
currHP -= damage;
healthSlider.value = currHP;
if (currHP <= 0)
makeDead ();



void makeDead()
Destroy (gameObject);




Here is my Serialization class:

Serialization

public static class Helper

//Serialze
public static string Serialize <T> (this T toSerialize)
XmlSerializer xml = new XmlSerializer (typeof(T));
StringWriter writer = new StringWriter ();
xml.Serialize (writer, toSerialize);
return writer.ToString ();


public static T Deserialize<T> (this string toDeserialze)
XmlSerializer xml = new XmlSerializer (typeof(T));
StringReader reader = new StringReader (toDeserialze);
return (T)xml.Deserialize (reader);

You going with XML and the process will be similar but I will answer with JSON.

First you have your SaveState as Serializable

[System.Serializable]
public class SaveState

public float FullHealth = 10; //The value that i Want
public float staminaPTS;



At that point you can turn that into JSON with JsonUtility:

SaveState ss = new SaveState();
ss.FullHealth = 10f;
ss.staminaPTS = 20f;
string json = JsonUtility.ToJson(ss);
PlayerPrefs.SetString("Save", json);


next you want to retrieve:

string json = PlayerPrefs.GetString("Save", null);
if(string.IsNullOrEmpty(json) == true) return; // no saving
SaveState ss = JsonUtility.FromJson<SaveState>(json);
Debug.Log($"ss.FullHealth ss.staminaPTS");


simple and does not require external libraries as JsonUtility is part of UnityEngine.

I'm pretty sure I'm not understanding your question, but will

bulan_fullhp = stateRef.FullHealth;


not do exactly what you want in this case?
