Is this possible? For I am trying it, and currently it is not working..

Won't do as last time and post all the code Smiley

Here's the object with the paintComponent():
1  
2  
3  
4  
5  
6  
7  
8  
9  
    public Platform() {
    }
   
    @Override
    public void paintComponent(Graphics g) {
        super.paintComponent(g);
       
        g.setColor(Color.gray);
        g.fillRect(0, 0, getBounds().width, getBounds().height);


The Platform-object is created first here:

1  
2  
3  
4  
5  
6  
7  
8  
9  
10  
11  
12  
13  
14  
15  
16  
17  
18  
19  
20  
    private class Level extends JPanel implements KeyListener, ActionListener {
        Platform ground = new Platform();
        Platform p1 = new Platform();
        Platform p2 = new Platform();
        Platform p3 = new Platform();
       
        public Level() {
            setPreferredSize(new Dimension(400, 400));
           
            ground.setBounds(0, 380, 400, 20);
            p1.setBounds(150, 200, 100, 20);
            p2.setBounds(100, 300, 200, 20);
            p3.setBounds(100, 360, 40, 20);
           
            add(ground);
            add(p1);
            add(p2);
            add(p3);
           
        }


(This private class does also have a paintComponent(), is that the problem..?)

Then the Level object is added to the JFrame in the superclass.

The mechanics of the platformer works just as I want it now, but having invisible platforms bothers me a bit : D

Huh?

I... would start by not making the platforms Swing objects... O_O

Yeah, you shouldn't be playing around with Swing components. They're not meant to be moved around and manipulated like that :S

Make Level extends JComponent and make Platform not extend anything, but keep a paint or paintComponent method. Then you directly call the Platform's render methods from Level's paintComponent.
