How to prevent losing multiple lives at zero health?

Questions & Answers

Hi all,
I am having the problem that between the time my player’s health reaches zero and the death animation finishes, if the player collides with another enemy, the player will continue to lose lives. Here is my code if anyone has any suggestions. I tried a coroutine with yield WaitForSeconds in the HealthScript, but that didn’t seem to help:

HealthScript:

public void Damage(int damageCount)//Inflicts damage
	{
	hp -= damageCount;

	if (hp <= 0 && this.gameObject.tag == "Player") {
	MainScript playerLives = this.GetComponent<MainScript> ();
	playerLives.UpdateLives (1);  //player lives minus one
	}
}

MainScript:

   public void UpdateLives(int livesLost){
    playerLives -= livesLost;
    HealthScript playerHealth = this.GetComponent<HealthScript> (); //get player health script
    if (playerLives > 0){
    StartCoroutine ("DieAnim");
}

private IEnumerator DieAnim ()
	{
		animator.SetInteger ("AnimState", 1);
		yield return new WaitForSeconds(1);//death animation plays
		Application.LoadLevel (Application.loadedLevel);//reload the current level
		}

fire some flag in your Coroutine, and dont decrement lives in UpdateLives if this flag is fired

UpdateLives() {
 if(!iAmDying) {
   ...
 }
}

DieAnim() {
  iAmDying = true;
  ...
}

you just need to move the check

 if (playerLives > 0)

in the Damage script like this:

    public void Damage (int damageCount)//Inflicts damage
    {
        // insert check here
        if (playerLives > 0) {
            hp -= damageCount;
            if (hp <= 0 && this.gameObject.tag == "Player") {
                MainScript playerLives = this.GetComponent<MainScript> ();
                playerLives.UpdateLives (1); //player lives minus one
            }
        }
    }
