how to make an 2d object move the direction its facing using rigidbody2d.velcoity

Could you post your actual code? What you've got there won't compile and I can't tell what you are trying to do.

 using UnityEngine;
 using System.Collections;
 
 public class NewBehaviourScript : $$anonymous$$onoBehaviour {
 
     public float speed = 5f;
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () { 
 
 
 
         GetComponent<Rigidbody2D>().AddForce(transform.right * speed ,Force$$anonymous$$ode2D.Force);
     
     }
 }
 

// i changed it to add force since i whouldnt compile but i would there use velocity ins$$anonymous$$d thank you
