<source lang="Java" line start= "1">
using UnityEngine;
using System.Collections;

public class CameraFollow : MonoBehaviour {

	public GameObject target;
	public bool orBitY = false;

	private Vector3 positionoffset = Vector3.zero;

	// Use this for initialization
	void Start () {
		positionoffset =  transform.position - target.transform.position ;
	}
	
	// Update is called once per frame
	void Update () {
	
		if (target != null) {
			transform.LookAt (target.transform);

			if (orBitY)
				transform.RotateAround (target.transform.position, Vector3.up, Time.deltaTime);

			transform.position = target.transform.position + positionoffset;
		}
	}
