How to shoot or spawn bullet with player direction in unity

Hello, In my unity 2D game I am generate bullet but issue is that bullet generate same position.it cannot generate with player direction or movement so how I can solve this issue

This is my Bullet Script

 public class WeaponScript : MonoBehaviour {

 public int speed=6;

 public Rigidbody2D rd;
 // Use this for initialization
 void Start () {
     rd = GetComponent<Rigidbody2D> ();
     Vector3 v = rd.velocity;
     v.x = speed;
     rd.velocity = v;
 }
 

}

This is my playerscript when i generate bullet

 public void ShootWeapon(){
     Instantiate (weaponShoot,transform.position,Quaternion.identity);
 }
