How to regenerate player's health after timer countdown is done.

Questions & Answers

HI, I have a script that regenerates player’s health after 5 seconds:

  float counter;

    void  Update (){
          counter += Time.deltaTime;
           if(counter > 30minutes){
              curHealth++;
                counter = 0.0f; }
              if(curHealth > 5)
                 curHealth = 5;
                 }

Which is attach to my player’s health script. I want to start regenerating my player health back when timer is at 0. But I don’t know how.
This is my player health script:

//Stats
public int curHealth;
public int maxHealth = 3;
public Collider2D col;
public PlayerHealth playerhealthRef;
public TimeManager countDownTimer;
float counter;
public Animator anima; // drag the panel in here again
private UI_ManagerScripts UIM;
DateTime currentDate;
DateTime oldDate;

private GenerateEnemy generateEnemy = null;


void Start ()
{
	curHealth = maxHealth;
	currentDate = System.DateTime.Now;
	if (countDownTimer != null)
	{
		// countDownTimer.gameObject.SetActive(false);
		countDownTimer.Enable(false);
	}
	if (GameObject.Find("Spawner"))
	{
		generateEnemy = GameObject.Find("Spawner").GetComponent<GenerateEnemy>();
	}
}


void Update ()
{
	counter += Time.deltaTime;
	if (curHealth > maxHealth) {
		curHealth = maxHealth;
	}
	if ((curHealth <= 0) && (!countDownTimer.gameObject.activeSelf)) {
		
		Die ();
	}
	if(counter > 5)
	{
		curHealth++;
		counter = 0.0f; 
	}
	if(curHealth > 3)
		curHealth = 3;
}


void Awake()
{
	UIM = GameObject.Find ("UIManager").GetComponent<UI_ManagerScripts> ();
}

void Die() {
	UIM.EnableBoolAnimator(anima);
	PlayerPrefs.SetInt("RemainingLives", curHealth);
	PlayerPrefs.Save();
	
	if (generateEnemy != null)
	{
		generateEnemy.DestroyAllBlobs();
	}
	if (countDownTimer != null)
	{
		countDownTimer.Enable(true);
	}
}	
public void Damage(int dmg)
{
	curHealth -= dmg;
}
 }

And this is my Timer countdown script:

public Text timer;
int minutes = 1;
int seconds = 0;
float miliseconds = 0;

[Range(1, 59)]
public int defaultStartMinutes = 1;
public bool allowTimerRestart = false;
public bool useElapsedTime = true;

private int savedSeconds = -1;
private bool resetTimer = false;

private DateTime centuryBegin = new DateTime(2001, 1, 1);

private float tickPerSecond = 10000000.0f;

public void Enable (bool enable)
{
	gameObject.SetActive(enable);
	ResetTime(); // force the timer to restart
}

void Awake ()
{
	minutes = defaultStartMinutes;
	if (PlayerPrefs.HasKey("TimeOnExit"))
	{
		miliseconds = PlayerPrefs.GetFloat("TimeOnExit");
		savedSeconds = (int)miliseconds;
		
		if (useElapsedTime && PlayerPrefs.HasKey("CurrentTime"))
		{
			int elapsedTicks = (int)(DateTime.Now.Ticks / tickPerSecond);
			int ct = PlayerPrefs.GetInt("CurrentTime", elapsedTicks);
			PlayerPrefs.DeleteKey("CurrentTime");
			elapsedTicks -= ct;
			if (elapsedTicks < miliseconds)
			{
				miliseconds -= elapsedTicks;
			}
			else
			{
				miliseconds = 0;
			}
		}
		
		minutes = (int)miliseconds / 60;
		miliseconds -= (minutes * 60);
		
		seconds = (int)miliseconds;
		miliseconds -= seconds;
		
		PlayerPrefs.DeleteKey("TimeOnExit");
		
	}
	savedSeconds = 0;
}

public void Update()
{
	// count down in seconds
	miliseconds += Time.deltaTime;
	if (resetTimer)
	{
		ResetTime();
	}
	if (miliseconds >= 1.0f)
	{
		miliseconds -= 1.0f;
		if ((seconds > 0) || (minutes > 0))
		{
			seconds--;
			if (seconds < 0)
			{
				seconds = 59;
				minutes--;
			}
		}
		else
		{
			resetTimer = allowTimerRestart;
		}
	}
	
	if (seconds != savedSeconds)
	{
		//  Show current time
		timer.text = string.Format("{0}:{1:D2}", minutes, seconds);
		savedSeconds = seconds;
	}
}

void ResetTime()
{
	minutes = defaultStartMinutes;
	seconds = 0;
	savedSeconds = 0;
	miliseconds = 1.0f - Time.deltaTime;
	resetTimer = false;
}

private void OnApplicationQuit()
{
	int numSeconds = ((minutes * 60) + seconds);
	if (numSeconds > 0)
	{
		miliseconds += numSeconds;
		PlayerPrefs.SetFloat("TimeOnExit", miliseconds);
		
		if (useElapsedTime)
		{
			int elapsedTicks = (int)(DateTime.Now.Ticks / tickPerSecond);
			PlayerPrefs.SetInt("CurrentTime", elapsedTicks);
		}
	}
}

}

Thank you :slight_smile:

The easiest way would be to first add the following to your uses statements at the top of your timer script

using UnityEngine.SceneManagement;

next modify the Update() function in the timer script to look like this

public void Update()
{
    // if we are still counting down
    if (((minutes * 60) + seconds) > 0)
    {
		// count down in seconds
		miliseconds += Time.deltaTime;
		if (resetTimer)
		{
			ResetTime();
		}
		if (miliseconds >= 1.0f)
		{
			miliseconds -= 1.0f;
			if ((seconds > 0) || (minutes > 0))
			{
				seconds--;
				if (seconds < 0)
				{
					seconds = 59;
					minutes--;
				}
			}
			else
			{
				resetTimer = allowTimerRestart;
			}
		}
	
		if (seconds != savedSeconds)
		{
			//  Show current time
			timer.text = string.Format("{0}:{1:D2}", minutes, seconds);
			savedSeconds = seconds;
		}
	}
    else
    {
        // reload the current scene
	    SceneManager.LoadScene(SceneManager.GetActiveScene().name);
    }
}

This essentially reloads the scene when the timer hits 0.
