How to make player stop running when touches a tagged object

Unity Engine

Hi everyone
I’ll start explaining how my game goes: my player is always running. What I want is that when he stand on an tagged object, the float named moveSpeed be equal to 0, in other words, he stop running

public class GlenController : MonoBehaviour {

    public float moveSpeed;
    public float jumpForce;
    private Rigidbody2D rb2d;
    public bool grounded;
    public LayerMask whatIsGround;
    private Collider2D myCollider;
    private Animator anim;

    // Use this for initialization
    void Start () {
        rb2d = GetComponent<Rigidbody2D> ();
        myCollider = GetComponent<Collider2D> ();
        anim = GetComponent<Animator> ();
    }
   
    // Update is called once per frame
    void Update () {

        grounded = Physics2D.IsTouchingLayers (myCollider, whatIsGround);

        rb2d.velocity = new Vector2 (moveSpeed, rb2d.velocity.y);
        if (CrossPlatformInputManager.GetButtonDown ("Jump")) {
            if (grounded) {
                rb2d.velocity = new Vector2 (rb2d.velocity.x, jumpForce);
            }
        }
        if (CrossPlatformInputManager.GetButtonDown ("Slide")) {
            anim.SetBool ("slide", true);
        }
        else if (!CrossPlatformInputManager.GetButtonDown("Slide")){
            anim.SetBool ("slide", false);
        }

        anim.SetFloat ("Speed", rb2d.velocity.x);
        anim.SetBool ("Grounded", grounded);
    }
}

You could create a trigger collider on those positions, and set the trigger event to fire to modify moveSpeed, within your GlenController

private void OnTriggerEnter2D(Collider2D collision)
    {
        if(collision.transform.tag == "StopTag")
        {
            moveSpeed = 0;
        }
    }
