sprite mover

[nodevelop]

hi
how can I set 2 state for a sprite.
I mean I have 2 image of the same sprite: spriteOn.png and spriteOff.png
I can simply draw them on the display using the paint method.
but how can I alternate them using a fixed time (about 500 ms)?
I tryied to use the wait and the timer method with no success.
a simply example code will be very wellcome.

thanks

try to use System.currentTimeMillis() and check time while you repaint (if you use another thread to update) or simple - use timer. hmmm...but what do you want to do? an idea depends on expected result.

A simple thread should do it... the thread is created by

Thread paintThread = new Swaper();
paintThread.start();

and the code for the thread:

private class Swaper extends Thread{
public Swaper (){
//constructor
}

public void run(){
this.setPriority(Thread.MIN_PRIORITY);
while (true){
something.repaint();
}

try{
this.sleep(500);
}catch (Exception e){
}
}

and instead of something.repaint();
in the thread you could have a method that swaps the images and repaints or something...
