How do I drew clock



  • I'm working on a project with my programming professor to write a new curriculum for the IST 145 (entry-level programming) class, using Processing instead Java. (Since Processing is highly Java-based, it shouldn't cause any problems for higher programming classes).

    I wrote a few quick programs to acquaint myself with Processing. I did not think any of them through ahead of time. Here's the snippet I'm most "proud" of, from my analog clock drawing program:

    <FONT family="Courier New">  int h = hour();
      int m = minute();
      int s = second();
      Point hourOut = polarToScreen((float)(Math.PI/2 - h * (Math.PI/6) - m * (Math.PI/360) - s * (Math.PI/21600)), HOUR_LENGTH);
      Point minOut  = polarToScreen((float)(Math.PI/2 - m * (Math.PI/30) - s * (Math.PI/1800)), MINUTE_LENGTH);
      Point secOut  = polarToScreen((float)(Math.PI/2 - s * (Math.PI/30)), SECOND_LENGTH);</FONT>

    It's better formatted than that in real life, but I wanted to imagine you all putting fingerprints on your screen trying to comprehend the paranthesis hash.



  •  What's the big deal?  The parens are pretty clear.



  • Fingerprints? A good IDE highlights one bracket when you put the cursor on the other.



    Also, Linkification thinks Math.PI/2 is a URL. Heh.



  •  Any good editor can highlight matching parentheses, so no need to put fingerprints on my screen (in fact, for me this is The Real WTF).



  • Yes, I have such an editor. You are reading this in a browser, though, which generally does not have such a feature.



  • What happens if the time rolls over from (say) 8:59 to 9:00 between the "h" and "m" assignments?

    Anyhow, I'd find something like this easier to read (apologies if the syntax is incorrect):

    [code]float s = second() / 60.0f;
    float m = (minute() + s) / 60.0f;
    float h = (hour() + m) / 12.0f;
    Point hourOut = polarToScreen((float)(Math.PI / 2 - h * Math.PI * 2), HOUR_LENGTH);
    Point minOut = polarToScreen((float)(Math.PI / 2 - m * Math.PI * 2), MINUTE_LENGTH);
    Point secOut = polarToScreen((float)(Math.PI / 2 - s * Math.PI * 2), SECOND_LENGTH);[/code]

    And I have 21 years of programming experience.  I can read code with three levels of nested parentheses just fine without any highlighting.

    FTFMYSELF.

    I have 6 years of programming experience.  I can read code with three
    levels of nested parentheses just fine without any highlighting.

    I have 21 decades of programming experience. I can read code with thirty levels of nested parentheses even though I am blind and have no teeth.

    no teeth.
     

    Well you don't need teef for that, fo I'm not impreffed at all.

    I'm a level 21 coding wizard. I can read the code from the filthy mind of the person who wrote thirty levels of nested parentheses



  • Seriously. Come back when you've done Lisp in a bare-bones command-line editor - and no, emacs doesn't count.

    Ametures. I have 21 days of programming experience. I can read a plz send me teh codez forum post asking someone to interperet three levels of tested paranthesis without syntax highlighitng.

    Does joe count?

    Man, I feel old.

    Pffft, STFU and GTFO, I've played 21 before, and all of you are wrong. There are no parentheses...

    Does Amiga ADVSYS count?
