Animation in Java on top of JPanel

68 views Asked by stanisz93 At 13 September 2024 at 12:34

I have a JPanel where I have array of buttons. It's a kind of memory game, and I wont to show some few frames of animation, for example Double Point.

Here is a part of code: This animation is that some text is slowly showing and disappearing (I used also Alpha channel in those images) , but I don't know why when id should slowly disapearing it didn't like if of this image stay there.

public void paintComponent(Graphics g)
{

    //Image img = new ImageIcon("res\\double.png").getImage();

    //g.drawImage(img, 0, 0, this.getWidth(), this.getHeight(), null);
    t.start();
    Image img2 = new ImageIcon("res\\double\\double_0000"+i+".png").getImage();

    g.drawImage(img2, 0, 0, this.getWidth(), this.getHeight(), null);
}


@Override
public void actionPerformed(ActionEvent e) {

    i++;
    if(i>30)
    t.restart();

    repaint();
}

}
