Yes I know a similar question has been asked before but it was explained so poorly that I’m forced to ask the question again. Here is the function that is called when the enemy is chasing the player.

	void ChasePlayer()
	{
		one = false; //Ignore this
		two = false;  //Ignore this
		enemySpeed = 3; //Speed is increased from walking to running
		transform.LookAt (Player.position);  //Enemy faces the player
		transform.position = Vector3.MoveTowards(transform.position, Player.position, enemySpeed * Time.deltaTime);  // the enemy's position is equal to moving from it's current position to player position at running speed.
	}

Problem is that if the player jumps the enemy starts flying, how would I limit him from looking up at the player. Would it need to track something that isn’t jumping? An empty that the player is parented to maybe. Or is there some way of doing it in script?

You had to lock the y axis in a vector 3 like this. So the vector3 tracks the player x position, the player z position but not y since it’s set to the object’s y position which is always going to be at the same height as the object itself.

		Vector3 Targetposition = new Vector3 (Player.position.x, transform.position.y, Player.position.z);
		transform.LookAt (Targetposition);
