Hey, I'm making a small shooting-game. I have right now an ellipse which you can move with the arrowkeys from left to right and i have made a bullet which fires when you press a key. But my problem now is that i want the bullet to fire from the same position that my ellipse has. Right now the bullet only fires from the centre of the screen. How can I make the bullet (shot class) follow the ellipse's movement?

Thanks in advance!

My code:

1. //variables
   ball myBall;
   shot myShot;
   ArrayList enemies;
   
   void setup()
   {
     //size and shit
     size(400, 400);
     frameRate(60);
     smooth();
   
     //declare new instances of the classes
     myBall = new ball(200, 300);
     myShot = new shot(200, 300);
     enemies = new ArrayList();
   }
   
   void draw()
   {
     background(0);
     //run the classes
     myBall.run();
     myShot.displayShot();
   
     enemies.add(new enemies1());
     //add enemies
     for (int i = enemies.size()-1; i>= 0; i--)
     {
       enemies1 e = (enemies1) enemies.get(i);
       e.displayEnemies();
     }
     //remove enemies
     if (enemies.size() > height)
     {
       enemies.remove(0);
     }
   }
   
2. class ball {
   
   //Variables
     float xPos;
     float yPos;
     float sizeH = 50;
     float sizeW = 50;
     float speed = 3;
     float rightWall = 375;
     float leftWall = 25;
     float gravY = random(-1, 1);
   
   //constructor
     ball (float _xPos, float _yPos)
     {
       xPos = _xPos;
       yPos = _yPos;
     }
   
   //run everything in one method in first_game class
     void run()
     {
       display();
       movement();
       rightArrow();
       leftArrow();
     }
   //display the ball
     void display()
     {
       ellipse(xPos, yPos, sizeH, sizeW); //draw ellipse
       strokeWeight(2);
     }
   //move the ball
     void movement()
     {
       if (xPos >= rightWall) // bounce right
       {
         xPos = rightWall;
       }
   
       if (xPos <= leftWall) // bounce left
       {
         xPos = leftWall;
       }
     }
   //keyPressed right
     void rightArrow()
     {
       if (keyPressed)
       {
         if (key == CODED)
         {
           if (keyCode == RIGHT) // move right
           {
             xPos = xPos + speed;
           }
         }
       }
     }
   //keyPressed left
     void leftArrow()
     {
       if (keyPressed)
       {
         if (key == CODED)
         {
           if (keyCode == LEFT) // move left
           {
             xPos = xPos - speed;
           }
         }
       }
