How to instantiate a game object every time when space key is pressed

Question

I want to instantiate a game object every time when the space key is pressed. Please help me with some solution below is my code-

public class arrow : MonoBehaviour { public Rigidbody2D rb; public float speed; public GameObject arow; // Use this for initialization void Start () {

     }
 
 // Update is called once per frame
 void Update () {
     float x = Input.GetAxis ("Horizontal");
     if (x > 0) {
         MoveRight ();
     }
     if (Input.GetKeyDown (KeyCode.Space)) {
         Instantiate (arow);
     }

 }
 void MoveRight(){
     rb.velocity = new Vector2 (speed, 0);
 }
 void OnCollisionEnter2D(Collision2D col){
     if (col.gameObject.tag == "ball") {
         Destroy (gameObject);
     }
 }

For that you will need some boolean and set it to true whenever you press the button and set it to false whenever you release it for example:

 private bool SpacePressed=false;
     void Update
     {
          if (Input.GetKeyDown (KeyCode.Space)&& !SpacePressed)   
          {
             Instantiate (arow);
             SpacePressed=true;
          }
          else if (Input.GetKeyUp (KeyCode.Space))   
          {
              SpacePressed=false;
          }
     }

@prrashanthh FIrst of all you will have to Store a reference in your script right after you instantiate that object like so:

 GameObject myItem=(GameObject)Instantiate(Item, transform.position, transform.rotation);

Then you will have to AddForce to its Rigidbody component or simply Translate a Transform component in desired direction.
lAddForce
lTranslate

Hope That is clear enough)

First of all thanks for your reply. Actually, I want the game object to be instantiated at starting position and it should move in a straight way. It will be a great help if you can help me with the code. Thanks.
