              How do I change when my RigidBody 2D initializes? C# Question/Noob,How do I change when rigidbody initializes?
Currently, the ball immediately drops when i play the game, not waiting for me to press space. I want the ball to stay in a constant position until I press the space bar.
 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class movestartscreen : MonoBehaviour
 {
     public GameObject ballz;
     public Rigidbody2D ballzRigidBody;
     public Vector2 joe;
     public int x;
     public int y;
     // Start is called before the first frame update
     void Start()
     {
 
         ballzRigidBody = ballz.AddComponent<Rigidbody2D>();
         ballzRigidBody.mass = 0;  
     }
 
     // Update is called once per frame
     void Update()
     {
         transform.position = new Vector2(x, y);
         if (Input.GetKeyDown("space")) {
             x = x + 400;
             y = y + 400;
             ballzRigidBody.mass = 1;
         }
     }
 }
