How do I make my sprite go left or right when it hits a trigger?

I'm trying to make my character change directions when it hits a trigger at the end of the map but it isn't working. I've checked the bool through debug but its changes the way it should. using UnityEngine; using System.Collections;

public class bot : MonoBehaviour {

 public float WalkSpeed;
 private bool Direction;


 void Start () {
     Direction = true;
 }

 void Update () {
     if (Direction = true){
     botMovement1();
     }

     if (Direction = false){
         botMovement2();
     }
 }
 
 
 void botMovement1()
 {
     float AmtToMove = WalkSpeed * Time.deltaTime;

     transform.Translate(Vector3.right * AmtToMove, Space.World);                

 }

 void botMovement2()
 {
     float AmtToMove = WalkSpeed * Time.deltaTime;
     
     transform.Translate(Vector3.left * AmtToMove, Space.World);                
     
 }

 public void OnTriggerEnter2D(Collider2D otherObject) 
 {
     if (otherObject.tag == "RightTrigger"){
         Direction = false;
     }
     if (otherObject.tag == "LeftTrigger"){
         Direction = true;
     }
 }

}
