Lose a life when timer runs out

Questions & Answers
1

So I making a game with a timer but I don’t want to end the game when the timer runs out I want the user to lose a life so is there a way to do this? I have lives in the Player.cs but I can’t seem to implement it into the GameManager.cs code.

This is my GameManager.cs:

using UnityEngine; 
using System.Collections; 

public class GameManager : MonoBehaviour 
{ 
	public int timeForLevel = 20; 
	private CountdownTimer myTimer; 
	public Player player;

	private void Start() 
	{ 
		myTimer = GetComponent<CountdownTimer>(); 
		myTimer.ResetTimer(timeForLevel); 
		
//		print ("Timer started"); 
	} 
	
	private void Update() 
	{ 
		CheckGameOver(); 
	} 
	
	// GAME OVER if seconds < 0 !!!!! 
	private void CheckGameOver() 
	{ 
		int secondsLeft = myTimer.GetSecondsRemaining(); 
		
		if(secondsLeft == 0) 
		{ 
			player.lives--; 
		} 
	} 
}

And this is my CountdownTimer.cs:

using UnityEngine;
using System.Collections;

public class CountdownTimer : MonoBehaviour 
{
	private float countdownTimerStartTime;
	private int countdownTimerDuration;
	
	public int GetTotalSeconds()
	{
		return countdownTimerDuration;
	}
	
	public void ResetTimer(int seconds)
	{
		countdownTimerStartTime = Time.time;
		countdownTimerDuration = seconds;
	}
	
	public int GetSecondsRemaining()
	{
		int elapsedSeconds = (int)(Time.time - countdownTimerStartTime);
		int secondsLeft = (countdownTimerDuration - elapsedSeconds);
		return secondsLeft;
	}
	
	public float GetProportionTimeRemaining()
	{
		float proportionLeft = (float)GetSecondsRemaining() / (float)GetTotalSeconds();
		return proportionLeft;
	}
}

Am I supposed to put it in the GameManager.cs code?

And this is my Player.cs code just in case you need to see it:

using UnityEngine;
using System.Collections;

/** 
	\for the player character
	\author Michelle Ruth
	\date    2014
	
	\warning not finished, health needs to be added and time
*/

public class Player : MonoBehaviour {

	private CountdownTimer myTimer;

	private int score = 0;
	private int lives = 3;
	private int DEATH_Y = -10;

	public Texture2D LivesLeft1;
	public Texture2D LivesLeft2;
	public Texture2D LivesLeft3;
	
	public int GetScore(){
		return score;
	}

	public int GetLives()
	{
		return lives;
	}

	private void Awake()
	{
		myTimer = GetComponent<CountdownTimer>();

	}
	
	private void Update()
	{
		float y = transform.position.y;
		
		if (y < DEATH_Y) {
			MoveToStartPosition();
			lives--;
		}

		if (score == 10)
		{
			Application.LoadLevel("Level2");
		}

		if (lives <= 0)
		{
			Application.LoadLevel("GameOver");
		}
	}

	private void OnGUI()
	{
		GUILayout.BeginHorizontal ();
		DisplayLives();

		int secondsLeft = myTimer.GetSecondsRemaining();
		string timeMessage = "Seconds left = " + secondsLeft;

		GUILayout.Label(timeMessage);
		
		string scoreMessage = "Score = " + score;
		GUILayout.Label (scoreMessage);
	}

	private void DisplayLives()
	{
		int playerLives = GetLives();
		
		if (1 == playerLives) {
			GUILayout.Label(LivesLeft1);
		}
		
		if (2 == playerLives) 
		{
			GUILayout.Label(LivesLeft2);
		}
		
		if(3 == playerLives){
			GUILayout.Label(LivesLeft3);
		}
	}

	private void MoveToStartPosition()
	{
		Vector3 startPosition = new Vector3(0,5,0);
		transform.position = startPosition;
	}

	/**
	 * what increases the score
	 * anything with the tag Hidden
	*/
	private void OnTriggerEnter(Collider c)
	{
		string tag = c.tag;
		
		if("Hidden" == tag)
		{
			score++;
		}

		if("Incorrect" == tag)
		{
			audio.Play ();
		}
	}
}

In the GameManager.cs where it says player.lives–; is the main part where I want to know if I can do this or if there is a particular way in doing it

Hi,

Have you considered using StartCoroutine.

Example :

private float expireTime = 5;
private bool removeHp;

void Start () {
		
		removeHp = false;
		StartCoroutine(StartRemoveHpAfterSomeTime());
	}

IEnumerator StartRemoveHpAfterSomeTime() {
		//Wait for the timer to count up to the expireTime
		//and then start removing hp
		
		yield return new WaitForSeconds(expireTime);
		
		// You can then start another coroutine to remove the hp here
            // or work with the update function...

            removeHp = false;
	}
