Question by TylerDean3211 · May 26, 2016 at 12:48 PM · error message

Vector2.Distance question. Code isnt working. Keeps throwing errors.

I'm trying to determine if the distance between my player and enemy is greater than the minimum distance. Then I'm moving the enemy toward the player. However the code i'm using in the if statement to check the distance keeps throwing an error. It says object reference not set to an instance of an object.

If anyone could help that would be awesome!

Here's the code:

  if (Vector2.Distance(transform.position,player.transform.position) >= minDistance)
         {
             //moves enemy towards enemy//
             transform.position = Vector2.MoveTowards(transform.position, player.transform.position, speed * Time.deltaTime);
         }

Like this?

 if (player != null && Vector2.Distance(transform.position, player.transform.position) >= $$anonymous$$Distance)
 {
     //moves enemy towards enemy//
     transform.position = Vector2.$$anonymous$$oveTowards(transform.position, player.transform.position, speed * Time.deltaTime);
 }
 else
 {
     Debug.Log("Player Is Null or not within distance");
 }

That logs the null thingy also when player is not null but the player is close enough :)
