Hey guys, ive been away from unity scripting for a month or two, and its made me forget lots of the basics. I cant seem to work out why this script isn’t working.

var Player : Transform;

function OnTriggerEnter( Player: Collider)

	{  
		var other : run_away_enemy = gameObject.GetComponent(run_away_enemy);
   
		other.change_come ();
	}
	
function OnTriggerExit( Player: Collider)

	{
		var other : run_away_enemy = gameObject.GetComponent(run_away_enemy);
  
		other.change_run ();
	}

When the game is running, if the player enters and exits the collider, these are the errors I get.

“NullReferenceException: Object reference not set to an instance of an object on_trigger_swarm.OnTriggerExit (UnityEngine.Collider Player) (at Assets/Scripts/on_trigger_swarm.js:16)”

and

" NullReferenceException: Object reference not set to an instance of an object on_trigger_swarm.OnTriggerEnter (UnityEngine.Collider Player) (at Assets/Scripts/on_trigger_swarm.js:8)"

I don’t think its relevant…but these are the functions that I am trying to call.

function change_come ()
{
Debug.Log ("true");
	attack = true;
	
}


function change_run()
{		
Debug.Log ("false");
		attack = false;

}

Any help would really be appreciated!

Thanks

Are you sure the object with on_trigger_swarm attached also has the run_away_enemy component attached?
