I've got a great idea on how to implement component based programming in C, and I'm excited to start coding it in. (The complete failure will be a great learning experience)  Evil
C ? I'm expecting to see you in the grumpy programmer room before long.

How can you complete anything with such pessimism?

Anyways I've been lazying out of doing it, but I'm finally getting around to doing it now.
(Also, I'm picking up C at the same time.  :D I am an ambitious one.)
I started to become a little confused as to how I'd come around doing to doing this, but the discovery of pointers to functions has cleared everything up for me once again.  Smiley

hmm...experienced an odd bug today.  I just fixed it, so I guess it should be happy, but I'm more..still perplexed. 

There was some collision code that was working fine on osx, but completely screwing itself up on xp.  Of all pieces of code, collision stuff is the stuff one tends not to worry about portability issues with.  The snippit looked like

if (blah(&x))
{
   player.x=x;
}

however, trying to cout the value of x (for debugging purposes) fixed everything

if (blah(&x))
{
    std::cout<<x;
    player.x=x;
}

This is not acceptable bugfix, needless to say.  Moving the code from another .cpp file to the main one (or rather, tossing the definition in the header file) fixed things.  So I should be happy, but I am still somewhat troubled by it...

Nothing weird going on like multiple threads accessing the player object (or stuff in your conditional)?  Or some other kind of race condition sort of thing?

No threading at all.

I think I've had this happen when I was using uninitialized variables or something like that... can't really remember. It's just one of those things... Do you reckon the problem might've been with &x and/or inside blah()?

Might also be worth cleaning the whole project and recompiling from scratch. Leftovers are BAD.

Yeah, something that breaks inexplicably and starts working again by writing seemingly unrelated code sounds to me like either uninitialized variables or a buffer overrun of some kind.

Ah, wait, I think I have it now; I'm pretty sure it's because I incorrectly labelled the function with __attribute__((const)).  Can't say I'm much in the mood to change the code back to test out this hypothesis, though.

I ... really think that BOOST_FOREACH is one of the most beautiful things I've seen done in C++; each time I have occasion to use it (not infrequently) it sets my heart a'flutter.

Tried to use code inputs and srand to control the random generation of a puzzle I was generating, but for some reason it just wasn't working. So i put it away, went to bed, and the next morning it inexplicably started working, and it's been working ever since. Hey, I'm not going to complain.

Did that start as the Mona Lisa or was it's target the Mona Lisa?

It targeted Mona Lisa. Also, here is the first attempt  Grin

I'm happy, because the very first time in my entire programming life, I'm coding something and it just works. OK, maybe not perfectly on the first try, there are still some game-breaking bugs and null references and stuff like that, but they're not of the motivational-killing "I just can't find or fix them" kind.

In other words, I haven't faced a problem I couldn't solve on my own yet with this project and I feel pretty confident it will stay that way, which makes me very happy Beer!

Also, I've finally managed to pick up a language and STICK with it. I've resisted countless temptations to pick something different (iPhone *wimper*) probably more interesting (or probably not) and decided to keep with the current language (which is AS3, by the way). And I intend to keep it that way until I've really mastered this one (and that is in my book when I can code down a good game in about a day without having to look at the documentation all the time).

I'm happy right now Grin

I've finally found a reason to use boost::variants.  A spurious reason, but, a reason nonetheless.  Hurrah!

I'm happy that I'm beginning to "get" Obj-C.  Not that it's difficult, just the whole [obj giggidy] looked strange. obj->giggidy()!

Also happy that I finished going through a new book! Beginning iPhone Development - Exploring the SDK

Let's see if I can make something useful fun

My tool suite (for areas, 'sub-areas,' animated sprites, cutout-style animations and parallax backdrops) is basically all done (barring unseen, minor corrections in the future).

This makes me a happy programmer.

I have written the pseudocode for simulating social aspect of concurrently running actors. Hooray!

Find a way to simulate behavior control between two actors and I will be super-happy. Grin

I've had a great weekend coding!

Got a safe Texture class up, TextureManager working, wrote my entity system to use my Sprites, sub-classed Entities into my AI Behaviour system, ported my AI Behaviour system from a 3D project I was working on so it can now be used with any base Entity type, added a couple support classes and methods like Log class (that tested my templated Singleton class) and openGL error support. Bit of everything really and it all works! Smiley Smiley Smiley

All this and managed to spend quality time with my girlfriend and see friends for a few beers.

Happy days  Smiley

This isn't a current thing, but rather an anecdote that just popped into my head.  A lecturer at my old university said it maybe three years ago.

He said that, one day, his son (who's around eleven or twelve) came to him and said that he was interested in learning some programming.  The guy was pretty delighted, but very quickly found himself thinking very seriously about what language would, in fact, be best to teach his son, that would teach him as many different facets of programming as possible.

Can you think of what language he chose?
