flicker

[angel_eyez]

//christmas tree
window.setColor(Color.green);
int[] tCoordinates = {210, 190, 200, 189, 195, 185, 175, 180, 165, 175, 155};
int[] sCoordinates = {230, 210, 210, 195, 195, 185, 195, 195, 210, 210, 230};
window.fillPolygon(tCoordinates, sCoordinates, tCoordinates.length);

Color newColor1 = new Color(88,58,31);
window.setColor(newColor1);
window.fillRect(173, 230, 15, 27);

//christmas tree ornaments
window.setColor(Color.red);
window.fillOval(178, 200, 07, 05);

Color newColor2 = new Color(15,89,4);
window.setColor(newColor2);
window.fillOval(181, 210, 07, 05);


window.setColor(Color.red);
window.fillOval(184, 220, 07, 05);



How do I make the ornaments flicker a different color? (red, green, blue, yellow, etc. [animation]) Using Thread.sleep?

Hello angel_eyez

Let your window be extended from the Thread class. You will need to override (or implement) to run() method. In the constructor of your window, call the start() method:

Code:

public void run(){
    try{
        Thread.sleep(100);
    } catch (Exception e) {
        // we normally ignore these exceptions
    }
    // Add your animation code here:
}

Just ask if you need more help.

tim: i think this is a bad idea to use Threads in Swing-AWT applications like that. you dont need to make your class extending a "Thread " for only using the sleep method. Thread.sleep() can be used arbitrarily in any class. Of course, this is not the best solution for the problem. Original pster may want to check the Swing Timers, or other timer facilities.

It depends on the programmer's style how he or she wants to implement threading. Many other programmers and books use this method. I, however, prefer to implement the Runnable interface. I understand what you mean by extending swing or AWT components as I have encountered threading problems in other languages like Borland Delphi.

Thank you
