How to select an object with TOUCH and change its animation 2D

Here is the thing!
I want to Touch a particular object in the screen and then change its animation.
I came up to this so far:
using UnityEngine;
using System.Collections;

public class Cop : MonoBehaviour {
	Animator anim;
	void Start () 
	{
		anim = GetComponent<Animator> ();
	}
	void FixedUpdate () 
	{
		if (Input.touchCount > 0 && Input.GetTouch (0).phase == TouchPhase.Began ) 
		{
			if(anim.GetBool("IsSelected")==false){
				anim.SetBool ("IsSelected",true);
			}
			else{
				anim.SetBool ("IsSelected",false);
			}
		}
	}
}

This changes the animation but when i press somewhere on the screen,but i want to change it only when the touch is on the particular object.I think something has to be done with raycast but i dont know what :frowning: .
Thanks in Advance!

I’ve hopefully found the answer at last…

using UnityEngine;
using System.Collections;

public class Target: MonoBehaviour {

	public	Animator anim;
	bool isSelected;
	void Start () 
	{
		anim = GetComponent<Animator> ();
	}
	void Update(){
		
		if (Input.touchCount > 0 && Input.GetTouch (0).phase == TouchPhase.Began) {
			
			Ray ray = Camera.main.ScreenPointToRay (Input.GetTouch(0).position);
			RaycastHit2D hit = Physics2D.Raycast (ray.origin, ray.direction);
			//Select Hool
			if (hit != null && hit.collider.transform.name == "Target") {
				isHit = false;
				//Destroy(GameObject.Find(hit.collider.gameObject.name));
				if (anim.GetBool ("IsSelected") == false) {
					anim.SetBool ("IsSelected", true);
					isSelected=true;

				} else {
					anim.SetBool ("IsSelected", false);
					isSelected=false;
				}
			}
