2d Turret WORKS but is turned 90 degrees from the right way

This script here works perfectly without error but its aim is off by 90 degrees

using UnityEngine;
using System.Collections;

public class TurretRotate : MonoBehaviour {
	
	public Transform target;
	public float turretSpeed;
	public float fireRate;
	public float fireBallHeight;
	public GameObject fireBall;
	public float range;
	private float _lastShotTime = float.MinValue;
	float distance;
	
	// Use this for initialization
	void Start () 
	{
		
	}
	
	// Update is called once per frame
	void Update () 
	{
		//Rotate turret to look at player.
		Vector3 relativePos = target.position - transform.position;
		Quaternion rotation = Quaternion.LookRotation(relativePos); 
		rotation.x=0;
		rotation.y=0;
		transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * turretSpeed);
		
		//Fire at player when in range.
		distance = Vector3.Distance(transform.position,target.position);
		
		if (distance < range && Time.time > _lastShotTime + (3.0f / fireRate))
		{
			_lastShotTime = Time.time;
			launchFireBall();
		}  
	}
	
	void launchFireBall()
	{
		Vector3 position = new Vector3(transform.position.x, transform.position.y + fireBallHeight, transform.position.z);
		Instantiate(fireBall, position, transform.rotation);
	}
}

How do I fix this?

lookrotation is meant to work with 3D Objects, facing along the z-Axis. making it work with 2D works like this: arrange the sprite so it points in the direction of the y-Axis. Use the two parameter version of lookrotation, with the first being Vector3.Forward and the second your aim direction.

Hey I have had the same problem and think I have found a way to do this quite simply. I would love your imput as its both a question and an answer. Using quaternions in 2D to follow a rotation. Both question and an Answer. - Unity Answers
