OnTriggerEnter Enemy not hitting me if I am already inside trigger

Questions & Answers

The problem with the following code is that if an enemy hits me invincible becomes true and after 2.5 seconds it becomes false again meaning I can once again get hit, however, if I am colliding with the trigger when invincible becomes false I dont get hit. In order for me to once again get hit I need to move out of the trigger first then re-enter it. Any solutions?

function OnTriggerEnter (other : Collider)
{
	if (!invincible)
	{
   		if(other.gameObject.tag == "Enemy")
    	{
    		hit = true;
       	 	invincible = true;
        	yield WaitForSeconds (2.5);
        	invincible = false;
    	}
	}
}

Add an OnTriggerStay() function to your script as well to account for that. Like so:

function OnTriggerStay (other : Collider)
{
  if (!invincible)
    OnTriggerEnter(other);
}

This way, while you are staying inside the trigger it forces the OnTriggerEnter() event whenever invincible is false. Hope that helps you out.
