How to make all objects pause in the game when i press pause button ?

i created a pause button and dragged the script to the button then when i press the button while playing the game i'v pressed the pause button everything stops and i mean by everything : dying when approach from obstacles and picking up coins but the enemies keeps moving and the player also

here is my pause code

 using UnityEngine;
 using System.Collections;
 
 public class PauseGame : MonoBehaviour {
     public bool paused;
     // Use this for initialization
     void Start () {
         paused = false;
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 
     public void Pause (){
 
         paused = !paused;
         if (paused) {
 
             Time.timeScale = 0;
         }
 
         else if(!paused) {
 
             Time.timeScale = 1;
         }
     }
 }
 

here is my player controller script using UnityEngine; using System.Collections;

 public class PlayerController : MonoBehaviour {
     public float jumpPower;
     public float speed;
     public bool moveLeft;
     public bool moveRight;
     public Rigidbody2D rigidbody2D;
     public Animator animator;
     public ScoreManager scoreManager;
 
 
     // Use this for initialization
     void Start () {
         rigidbody2D = gameObject.GetComponent<Rigidbody2D> ();
 
     }
     
     // Update is called once per frame
     void Update () {
         
         
         if (moveLeft)
             MoveLeft ();
         if (moveRight)
             MoveRight ();
         
     }
     public void MoveLeft()
         
     {
         transform.position = new Vector3 (transform.position.x - speed, transform.position.y, transform.position.z);
         animator.Play ("Walk");
         transform.localScale = new Vector3 (-.75f, transform.localScale.y, transform.localScale.z);
         
     }
     
     public void MoveRight()
     {
         transform.position = new Vector3 (transform.position.x + speed, transform.position.y, transform.position.z);
         animator.Play ("Walk");
         transform.localScale = new Vector3 (.75f, transform.localScale.y, transform.localScale.z);
         
     }
     
     public void ControlMoveLeftButton(bool val)
     {
         moveLeft = val;
         if (!val)
             animator.Play ("Idle");
     }
     public void ControlMoveRightButton(bool val)
     {
         moveRight = val;
         if (!val)
             animator.Play ("Idle");
     }
     public void Jump(){
         //rigidbody2D.AddForce (Vector3.up * jumpPower);
         rigidbody2D.AddForce (new Vector2 (0, 10), ForceMode2D.Impulse);
     }
     void OnTriggerEnter2D (Collider2D other)
     {
         if (other.tag == "Plastic") {
             Destroy (other.gameObject);
             scoreManager.IncreasePlasticCoins ();        }
         if (other.tag == "Light") {
             Destroy (other.gameObject);
             scoreManager.IncreaseLightCoins ();
         }
         
         if (other.tag == "Heavy") {
             Destroy (other.gameObject);
             scoreManager.IncreaseHeavyCoins ();
         }
         
         if (other.tag == "Ameba") {
             Destroy (other.gameObject);
             scoreManager.LostFiveCoins();
         } 
         
         if (other.tag == "Anthrax") {
             Destroy (other.gameObject);
             scoreManager.LostTenCoins();
         } 
         
         if (other.tag == "Dangerous") {
             animator.Play ("Die");
             Invoke("GameOver", 0);
         }
     }
     void GameOver() {
         Application.LoadLevel("GameOver");
         
     }
     
 }
 

and the enemy controller

 using UnityEngine;
 using System.Collections;
 
 public class EnemyController : MonoBehaviour {
     public float speed;
 
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () 
     
     {
         transform.position = new Vector3 (transform.position.x - speed, transform.position.y, transform.position.z);
 
 
     }
 
 }
