I'm currently working on a game like total war, i made a simple stop when it collides with something script but now I want the unit to move forward when the object exit the trigger my unit moves forward unitil he collides with a object.

my script

 using UnityEngine;
 using System.Collections;
 
 [RequireComponent (typeof(Rigidbody))]
 public class UnitAI : MonoBehaviour {
     public bool Selected = false;
     public GameObject selectedCirkle;
     public float health = 10;
     public bool Collided = false;
 
     public float moveSpeed= 20;
     public float stopSpeed = 0;
 
 
 
 
     // Use this for initialization
     void Start () {
         selectedCirkle.SetActive (false);
     }
     
     // Update is called once per frame
     void Update () {
     if (Selected == true && Collided == false) {
             transform.Translate(Vector3.forward * moveSpeed * Time.deltaTime);
 
                 }
     if (Selected == true && Collided == true) {
             transform.Translate(Vector3.forward * stopSpeed * Time.deltaTime);
             
         }
     }
     void OnTriggerEnter (Collider other){
         if (other.tag == "Unit") {
 
                         Collided = true;
                         
                 }
 
 
         }
     void OnTriggerExit (Collider other){
 
             
         Collided = false;
             
          
         
         
     }
 
 
 
     void OnMouseDown () {
         Selected = true;
         selectedCirkle.SetActive(true);
 
         }
 }
