My unity save system doesn't save integer array - arrays

Question

I don't get any errors but my script doesn't load or possibly save my array...
here's the first script
[System.Serializable]
public class PlayerData
{
public float health;
public float thirst;
public float hunger;
public float oxygen;
public float[] position;
public int[] inventoryIDs;
public PlayerData (Health healthO, SaveLoad saveload)
{
//Save int items
health = healthO.health;
thirst = healthO.thirst;
hunger = healthO.hunger;
oxygen = healthO.oxygen;
//set and save location array
position = new float[3];
position[0] = healthO.transform.position.x;
position[1] = healthO.transform.position.y;
position[2] = healthO.transform.position.z;
//set and save inventory IDs
inventoryIDs = new int[50];
for(int i = 0; i < 50; i++)
{
inventoryIDs[i] = saveload.IDs[i];
}
}
}
here's the next
public class SaveLoad : MonoBehaviour
{
public GameObject player;
public int[] IDs;
public GameObject[] objects;
Inventory inventory;
Health health;
void Start()
{
IDs = new int[50];
objects = new GameObject[50];
inventory = player.GetComponent<Inventory>();
health = player.GetComponent<Health>();
}
void Update()
{
//Add IDs
for (int i = 0; i < 50; i++)
{
IDs[i] = inventory.slot[i].GetComponent<Slot>().ID;
}
//debug save load test
if (Input.GetKeyDown(KeyCode.Z))
{
SaveP();
}
if (Input.GetKeyDown(KeyCode.X))
{
LoadP();
}
}
public void SaveP()
{
SaveSystem.SavePlayer(health, this);
}
public void LoadP()
{
PlayerData data = SaveSystem.LoadPlayer();
//load stats
health.thirst = data.thirst;
health.hunger = data.hunger;
health.health = data.health;
health.oxygen = data.oxygen;
//Load position
Vector3 position;
position.x = data.position[0];
position.y = data.position[1];
position.z = data.position[2];
player.transform.position = position;
//load IDs
for (int i = 0; i < 50; i++)
{
IDs[i] = data.inventoryIDs[i];
}
//Load Items
for (int i = 0; i < 50; i++)
{
if(objects[IDs[i]] != null)
{
GameObject itemObject = (GameObject)Instantiate(objects[IDs[i]], new Vector3(0, 0, 0), Quaternion.identity);
Item item = itemObject.GetComponent<Item>();
inventory.AddItem(itemObject, item.ID, item.type, item.name, item.description, item.icon);
} else
{
return;
}
}
}
}
Here's the last script
public static class SaveSystem
{
public static string fileName = "FileSave.bin";
public static void SavePlayer(Health health, SaveLoad SL)
{
//Create formatter
BinaryFormatter bf = new BinaryFormatter();
// Create file stream
FileStream file = File.Create(GetFullPath());
//Save data
PlayerData data = new PlayerData(health, SL);
bf.Serialize(file, data);
//Close stream
file.Close();
}
public static PlayerData LoadPlayer()
{
if (SaveExists())
{
try
{
//Create formatter
BinaryFormatter bf = new BinaryFormatter();
//Create file stream
FileStream file = File.Open(GetFullPath(), FileMode.Open);
//Load data
PlayerData pd = (PlayerData)bf.Deserialize(file);
//close stream
file.Close();
//return data
return pd;
}
catch (SerializationException)
{
Debug.Log("Failed to load file at: " + GetFullPath());
}
}
return null;
}
private static bool SaveExists()
{
return File.Exists(GetFullPath());
}
private static string GetFullPath()
{
return Application.persistentDataPath + "/" + fileName;
}
}
there are all connected with the save load script loading and saving the variables into the player and items to the inventory sots. the inventory IDs array isn't saving or loading
