How to Access GamePanel Dimensions from Within the Rect Class?

Getting Panel Dimensions Outside of Class

In your code, you need to obtain the dimensions of the GamePanel within the Rect class. To achieve this:

1. Add the GamePanel as a parameter to the move() method in the Rect class:

public void move(GamePanel panel) {
  // Use the panel dimensions here
}

2. In the GamePanel class, calculate the updated dimensions in the paint() method:

public void paint(Graphics g) {
  jpWidth = getWidth();
  jpHeight = getHeight();
  // ...
}

3. Pass the GamePanel instance to the move() method in the Rect class constructor:

public Rect() {
  // ...
  gamePanel.add(this);
}

4. Call the move() method with the GamePanel instance in the run() method of the GamePanel class:

public void run() {
  for (Rect rect : rect) {
    rect.move(this);
  }
  // ...
}
