I have a script to grab objects but it has alittle problem. can anyone check it?

Hello all. i have managed to get this from a tutorial and make it work for the oculus using OVRInput for the xbox buttons. It works for the most part, except if there are 2 or more objects within the range distance...it will grab all of them. HOw would i change it so that it only grabs the one I'm facing.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GrabThrowObject : MonoBehaviour {
	public Transform player;
	public Transform playerCam;
	public float throwForce = 10;
	bool hasPlayer = false;
	bool beingCarried = false;
	public AudioClip[] soundToPlay;
	private AudioSource audio;
	public int dmg;
	private bool touched = false;

	// Use this for initialization
	void Start () {
		audio = GetComponent<AudioSource> ();
	}

	// Update is called once per frame
	void Update () {
		float dist = Vector3.Distance (gameObject.transform.position, player.position);
		if (dist <= 2.5f) {
			hasPlayer = true;
			Debug.Log ("Able to grab");
		}
		else{   
			hasPlayer = false;
		}

		//Grab object. Bug is you can grab 2 or even 3 if in range
		if (hasPlayer && OVRInput.GetDown (OVRInput.Button.One) ) {  //Press A button
			GetComponent<Rigidbody> ().isKinematic = true;
			transform.parent = playerCam;
			beingCarried = true;
			Debug.Log ("Pressed A to grab");
		}

		if( beingCarried)
		{
			if (touched) {
				GetComponent<Rigidbody> ().isKinematic = false;
				transform.parent = null;
				touched = false;
			}
			if (OVRInput.GetDown (OVRInput.Button.Three ) ) {//Press X 
				GetComponent<Rigidbody> ().isKinematic = false;
				transform.parent = null;
				beingCarried = false;
				GetComponent<Rigidbody> ().AddForce (playerCam.forward * throwForce);
				RandomAudio ();
			}
			else if(OVRInput.GetDown(OVRInput.Button.Two)){  //Press B button to drop object
				GetComponent<Rigidbody>().isKinematic = false;
				transform.parent = null;
				beingCarried = false;
			}
		}
	}
	void RandomAudio(){
		if (audio.isPlaying) {
			return;
		}
		audio.clip = soundToPlay [Random.Range (0, soundToPlay.Length)];
		audio.Play ();
	}
	void OnTriggerEnter(){
		if (beingCarried) {
			touched = true;
		}
	}
}
