Why My player character can't change after go to main menu - unity3d

Question

I have game the name is quiz game RPG, and I have 1 problem with it, the problem is why after pressing to the town(which is the main menu) and change the character, play it again the character is not the current character but previous character, which is the index back to 0.
I have tried to add playerprefs on the start and change index but nothing changed. still back to 0 after that.
Character select script:
private void Start()
{
characterSelect = FindObjectOfType<_CharacterSelect>();
audioManager = FindObjectOfType<AudioManager>();
selectedCharIndex = PlayerPrefs.GetInt("Player",0);
UpdateCharacterUI();
character = charactersList[selectedCharIndex].Character;
isSold = PlayerPrefs.GetInt(selectedCharIndex + "IsSold", 0);
if (selectedCharIndex == 0)
{
if (isSold == 0)
{
PlayerPrefs.SetInt(selectedCharIndex + "IsSold", 1);
}
}
CheckStatus();
CallPlayer();
}
public void CallPlayer()
{
currentCharacter = Instantiate(character, new Vector3(-2.403f, -0.6f, 0f), Quaternion.identity);
}
private void Update()
{
StartCoroutine(SaveCharacter());
}
void CheckStatus()
{
moneyAmount = (int)PlayerPrefs.GetFloat("MoneyAmount");
isSold = PlayerPrefs.GetInt(selectedCharIndex + "IsSold", 0);
if (moneyAmount >= 0)
{
buyButton.interactable = true;
}
else
{
buyButton.interactable = false;
}
if (isSold == 1)
{
buyButton.gameObject.SetActive(false);
}
else
{
buyButton.gameObject.SetActive(true);
}
Debug.Log(moneyAmount);
Debug.Log(isSold);
}
public void LeftArrow()
{
moneyAmountText.text = moneyAmount.ToString() + "$";
audioManager.play("SFX");
selectedCharIndex--;
if (selectedCharIndex < 0)
{
selectedCharIndex = charactersList.Count - 1;
}
CheckStatus();
UpdateCharacterUI();
}
public void RightArrow()
{
moneyAmountText.text = moneyAmount.ToString() + "$";
audioManager.play("SFX");
selectedCharIndex++;
if (selectedCharIndex == charactersList.Count)
{
selectedCharIndex = 0;
}
CheckStatus();
UpdateCharacterUI();
}
public void Buy()
{
audioManager.play("Unlocked");
moneyAmount -= 0;
PlayerPrefs.SetInt(selectedCharIndex + "IsSold", 1);
buyButton.gameObject.SetActive(false);
PlayerPrefs.SetFloat("MoneyAmount", moneyAmount);
moneyAmountText.text = moneyAmount.ToString() + "$";
}
IEnumerator transition()
{
yield return new WaitForSeconds(2f);
Price.text = "Sold!";
}
public void Confirm()
{
audioManager.play("Confirm");
PlayerPrefs.SetInt("Player", selectedCharIndex);
Debug.Log(string.Format("Character{0}:{1} has been choosen", selectedCharIndex, charactersList[selectedCharIndex].CharName));
character = charactersList[selectedCharIndex].Character;
ChangeCharacter();
}
void ChangeCharacter()
{
Vector3 currentPosition = currentCharacter.transform.position;
Destroy(currentCharacter);
currentCharacter = Instantiate(character, currentPosition, Quaternion.identity);
cameraFollow = GameObject.FindGameObjectWithTag("MainCamera").GetComponent<CameraFollow>();
cameraFollow.GetPlayer(currentCharacter);
}
IEnumerator SaveCharacter()
{
if (saveChar)
{
saveChar = false;
yield return new WaitForSeconds(0.05f);
currentCharacter = Instantiate(character, new Vector3(-2.47699f, 0.169f, 0), Quaternion.identity);
cameraFollow = GameObject.FindGameObjectWithTag("MainCamera").GetComponent<CameraFollow>();
cameraFollow.GetPlayer(currentCharacter);
}
}
}
For the levelManager:
prvoid Start()
{
_CharacterSelect = FindObjectOfType<_CharacterSelect>();
audioManager = FindObjectOfType<AudioManager>();
selectLevel = FindObjectOfType<SelecLevel>();
gameManager = FindObjectOfType<GameManager>();
FillList();
}
void FillList()
{
Index = 0;
for (int i = 0; i < selectLevel.Levels; i++)
{
LevelButton levelButton = Instantiate(TheButton, Spacer).GetComponent<LevelButton>();
levelButton.LevelIndex = Index;
levelButton.button.onClick.AddListener(() => SelectLevel(levelButton.LevelIndex));
Index++;
}
}
void DeleteAll()
{
PlayerPrefs.DeleteAll();
Application.LoadLevel(0);
}
void SelectLevel(int index)
{
_CharacterSelect.saveChar = true;
selectLevel.levelIndex = index;
Application.LoadLevel("Level " + (index + 1));
switch (selectLevel.levelIndex)
{
case 1:
audioManager.StopPlay("BGM");
audioManager.play("BGM1");
break;
case 2:

Answer 1

solved,
it's confusing me all night though
:'D
but it's because I'm just not setting the playerprefs at Savecharacter line at Character select script
selectedCharIndex = PlayerPrefs.GetInt("Player");
character = charactersList[selectedCharIndex].Character;
