Question by scrimson · Dec 16, 2016 at 02:13 PM · collisioncollidertimefunctionseconds

How to make function last for X seconds?

I have a script where when my boomerang collides with an enemy, the enemy is disabled. However, the enemy is only set active for about half of a second. I want the enemy to be disable for 5 seconds (X seconds). Any help would be appreciated

Sorry, I'm new to Unity would like some guidance! Thanks!

     void OnCollisionEnter (Collision other) {
         if (other.gameObject.tag == "Enemy")
         {
             other.gameObject.SetActive (false);
         }
     }

Remember: If you want behavior with delay / timer you have to insert it in "IEnumerator" and call it through "StartCoroutine". Try this code:

 void OnCollisionEnter (Collision other)
 {
          if (other.gameObject.tag == "Enemy")
          {
              StartCoroutine (DisableEnemy (other.gameObject));
          }
  }
 
 IEnumerator DisableEnemy (GameObject enemy)
 {
    enemy.SetActive (false);
 
    yield return new WaitForSeconds (5f);
 
    enemy.SetActive (true);
 }
