player prefs issues

ok so after getting a fix for saving playerprefs using OnApplicationQuit(). i was able to get this to work once. when player runs of lives however and data is cleared to allow lives to be reset, i am met with 0 lives so game will not run. in unity runtime i am met with same issue and it no longer lets me play.

i’ll paste code below.

LivesManager

public class LivesManagerScript : MonoBehaviour {

public static int lives = 6;

void Awake()
{
	DontDestroyOnLoad (gameObject);
	PlayerPrefs.GetInt ("Lives",lives);
}

void Update()
{
	lives = PlayerPrefs.GetInt ("Lives");
}

void OnApplicationQuit() 
{
	PlayerPrefs.SetInt("Lives",CharacterMove.lives);
}

}

Start Button

public class StartButtonScript : MonoBehaviour {

public int lives = 0;
public int dJumps = 0;

void Start()
{
	lives = PlayerPrefs.GetInt ("Lives");
	dJumps = PlayerPrefs.GetInt ("DoubleJumps");
}

void Update()
{
	if (Input.touches.Length <= 0) {
		
	} 
	else 
	{
		for(int i = 0; i < Input.touchCount; i++)
		{
			if(this.guiTexture.HitTest (Input.GetTouch (i).position))
			{
				if(Input.GetTouch(i).phase == TouchPhase.Ended)
				{
					if(lives > 0)
					{
						Application.LoadLevel (1);
					}
				}
			}
		}
	}
}

}

Character Control

public class CharacterMove : MonoBehaviour {

public float speed = 6.0f;
Transform groundCheck;
private float overlapRadius = 0.2f;
public LayerMask whatIsGround;
private bool grounded = false;
private bool jump = false;
public float jumpForce = 700f;
private bool doubleJump = false;
public int sJumpsCompleted = 0;
public static int dJumpLimit = 0;
public static int lives = 0;


void Awake()
{
	rigidbody2D.fixedAngle = true;
}

void Start()
{
	groundCheck = transform.Find ("groundcheck");
	dJumpLimit = PlayerPrefs.GetInt ("DoubleJumps");
	lives = PlayerPrefs.GetInt ("Lives");
}

void Update()
{
	if (Input.GetMouseButtonDown (0)) 
	{
		jump = true;
		sJumpsCompleted++;
	}
	if (sJumpsCompleted > 9) 
	{
		dJumpLimit = dJumpLimit + 1;
		PlayerPrefs.SetInt ("DoubleJumps", dJumpLimit);
		sJumpsCompleted = 0;
	}
}

void FixedUpdate()
{
	
	//check if character is grounded
	grounded = Physics2D.OverlapCircle (groundCheck.position, overlapRadius, whatIsGround);
	
	//reset doublejump when player is on the ground
	if (grounded)
		doubleJump = false;
	//deactivate double jump when no jumps are available
	if (dJumpLimit < 1)
		doubleJump = true;
	
	//determine if player can jump
	bool canJump = (grounded || !doubleJump);
	
	if (jump && canJump) 
	{
		rigidbody2D.velocity = new Vector2(rigidbody2D.velocity.x,0);
		rigidbody2D.AddForce(new Vector2(0, jumpForce));
		if(!grounded && DoubleJumperManagerScript.dJumpLimit > 0)
		{
			doubleJump = true;
			dJumpLimit--;
			PlayerPrefs.SetInt ("DoubleJumps", dJumpLimit);
		}
	}
	
	jump = false;
	
	
	//apply forward movement
	rigidbody2D.velocity = new Vector2 (speed, rigidbody2D.velocity.y);
	
}

}

Retry Button

public class RetryButtonScript : MonoBehaviour {

void Update()
{
	DoubleJumperManagerScript.dJumpLimit = CharacterMove.dJumpLimit;
	LivesManagerScript.lives = CharacterMove.lives;
	
	
	if (Input.touches.Length <= 0) {
		
	} 
	else 
	{
		for(int i = 0; i < Input.touchCount; i++)
		{
			if(this.guiTexture.HitTest (Input.GetTouch (i).position))
			{
				if(Input.GetTouch(i).phase == TouchPhase.Ended)
				{
					if(CharacterMove.lives > 0)
						Application.LoadLevel (1);
				}
				else if(CharacterMove.lives < 1)
				{
					Application.LoadLevel (0);
				}
			}
		}
	}
}

}

so basically i just want be able to have the lives work as they did and when lives run out to be able to reset the values for testing.

this isn’t an answer because i don’t know where to begin.

it seems like you’re using PlayerPrefs to access variables from other scripts rather than getting a reference to a single copy of them using GetComponent<>(), etc.

you should think about rewriting the code to do that - you’ll have a lot less bugs, the code will be cleaner, easier to understand, and easier to maintain.

by all means, store variables that you want to persist between session using PlayerPrefs, but it’s not intended for doing what you appear to be using it for.

also, your start button and retry button scripts are almost identical - consider using the same script for both and handle the loading separately. try to have all the loading done in one place too… for the same reason as accessing your variables from one place.
