我的碰撞2d在Unity上的C＃中不起作用

Question

I'm learning C# while programming my game, I'm stuck doing the movement. I want my character to move continuously by pressing 'D' or 'A' once. Then, after colliding with an invisible wall while going to the right, go backwards until it hits another invisible wall and stop. I managed to make my GameObject move, but when it collides with the wall, nothing happens. Both objects have a rigidbody2D , the same z-coordinates, and correct tags.

public class SquadMovement : MonoBehaviour {

    float speed;
    bool collisionRightWall = false;

    // Update is called once per frame
    void Update () {

        if (Input.GetKeyDown (KeyCode.D)) {  

            CancelInvoke ();
            InvokeRepeating ("RightMovement", Time.deltaTime, Time.deltaTime);

        }

        if (Input.GetKeyDown (KeyCode.A)) {

            CancelInvoke ();
            InvokeRepeating ("LeftMovement", Time.deltaTime, Time.deltaTime);

        }
    }

    void RightMovement () {

        speed = 10f;
        transform.Translate (speed * Time.deltaTime, 0, 0);

    }

    void LeftMovement () {

        speed = -7f;
        transform.Translate (speed * Time.deltaTime, 0, 0);

    }

    void OnCollisionWallR (Collider2D colR) {

        if (colR.gameObject.tag == "invisibleWallRight") {

            collisionRightWall = true;
            Debug.Log (collisionRightWall);

        }
    }
}

I'm using invisible walls because I don't know how to use x-coordinates, There HAS to be a more efficient way but I want to know first why this don't work. I would be glad if someone could teach me that too.

using UnityEngine; using System.Collections;

public class SquadMovement : MonoBehaviour {

float constantspeed = 3;
float speed;

//Key inputs

void Update () {

    transform.Translate (constantspeed * Time.deltaTime, 0, 0);
    if (Input.GetKeyDown (KeyCode.D)) {  

        StopAllCoroutines ();
        StartCoroutine (RightMovement(0f));
    }

    if (Input.GetKeyDown (KeyCode.A)) {

        StopAllCoroutines ();
        StartCoroutine (LeftMovement(0f));
    }
}

//Movement itself (Right, Left)

IEnumerator RightMovement (float Rloop) {

    while (transform.position.x < Time.time * constantspeed + 6) {

        speed = 10f;
        transform.Translate (speed * Time.deltaTime, 0, 0);
        yield return new WaitForSeconds (Rloop);
    }

    if (transform.position.x > Time.time * constantspeed + 5.9) {

        StopAllCoroutines ();
        StartCoroutine (LeftMovement (0f));
    }
}

IEnumerator LeftMovement (float Lloop) {

    while (transform.position.x > Time.time * constantspeed -8) {

        speed = -7f;
        transform.Translate (speed * Time.deltaTime, 0, 0);
        yield return new WaitForSeconds (Lloop);
    }
}

}
