  1. Re: Cant get the ball to bounce around the canvass

    I did all updating on the EDT. The JPanel looked fine when rendering, no frames were wrong.
  2. Re: Cant get the ball to bounce around the canvass

    All I had was a JFrame which I added one JPanel to. When I switched to a Canvas I just had one JFrame with one Canvas on it. The only thing I changed in the rendering process was how I obtained the...
  3. Re: Cant get the ball to bounce around the canvass

    Not saying JComponents are bad or anything, if it's working for you then stick to it.
    I had an old game project once which used JPanels and repaint() for rendering. However, I noticed it started...
  4. Re: Cant get the ball to bounce around the canvass

    JComponents uses passive rendering (which means you have to wait for the EDT to render the JComponent).

    Also, that doesn't look like "very simple code" to me. "Hello world" is very simple code. If...

    Re: Incorrect Key Input

    if(key=='1')

    You are comparing an int to a char. Remove the single-quotes and compare key to an int instead.

    Also what error message are you getting?

    EDIT: keyDown is a deprecated method. I...

  18. Re: The java-output doesn't give the right result?

    If you remove the synchronized keyword from both methods then you would probably get different results every time you run the program.

  19. Re: The java-output doesn't give the right result?

    Basic math:
    3 * 2'000'000 = 6'000'000
    1 * 2'000'000 = 2'000'000

    Add them together and you get 8'000'000.
    How can 7'999'982 be the right output?

    Not necessarily weird syntax, but abusing the finally clause can produce some really weird results:
