I am new to java 2d graphics and I have problem handling mouseclick event.
Is it possible for you to tell me why there is nothing going on after updating mouse status to clicked ?
What I want to do is to change the image in array at 0 2 to another image. Nothing happens tho. Thanks for your help in advance.
