Programmers/Coders?

[Lord Sinister]

Kind of like the artists thread, but this time for programmers! I made a couple of threads about some C++ coding problems I'd had before that didn't attract too much interest, but there's plenty of other programming languages out there.

 

I'm learning how to code with the Windows API and DirectX. I've progressed beyond my original test-bed and made a small little program with bouncing objects. They're just squares colliding with each other, and I really need to think of ways I can optimise how I'm doing it. My brother seems to think I should have some sort of system that uses trigonometry, but I can't think how I'd do that right now.

 

For those interested, here's a couple of things, just extract it somewhere and run, then delete it afterwards. Hit F3 to display the framerate (which may be a little off), and hit Space to create objects. Hold it down to create lots and consume your framerate.

 

The framerate is inconsistent because the collision correction could probably be done more efficiently, and there is a random bug where occasionally everything freezes.

http://dl.dropbox.com/u/32830518/dxPongCollisionsSlower.rar The speeds the squares can move at are a little slower to make the collisions more easy to observe.

 

As the name implies, I'm making a pong clone, but I did get a little carried away with the collision system. Momentum is properly transferred I might add (mechanics world style, no momentum is lost).

 

(EDIT: It also appears to leak memory somewhere. If run for long enough it consumes up to 1.9GB of memory before presenting a runtime error. New task: Manage memory better).

 

So, anyone else here a programmer? Working on something interesting? Want to show your work? Post!

Indeed.

 

Hopefully others too! Crawling out of the woodwork and so on.

I learned Java throughout high school and was the top of my class, and I learned the same stuff again in college last semester, but I still don't know enough to anything cool. I am majopring in Game Design though, so hopefully I'll learn some good stuff soon.

 

I've also made some Flash Games with Actionscript 2.0, but once again it was never anything too difficult or cool. I just had one really good book that explained how to do almost everything.

I used to be a pretty decent programmer back in college: mainly C, a lot of Matlab and POV-Ray scripts (I have a mean animation of the basic components of an MRI machine)... but it's been at least 8 years since I wrote a single line of code. I'll check my files later, see if there's anything interesting.

 

( I also used to write some cool Atari BASIC programs... but they are now lost in the mist of time )

Ok, here's the animation I made for my thesis defense. It shows the main coils of a Magnetic Resonance Imaging Scanner and then continues on to the process of alignment of the spins, excitation and readout of the resulting signal. I've attached the POV-Ray scripts, in the off chance someone actually still uses POV-Ray and wants to check out the code.

A little explanation on MRI: our body is composed primarily of water. The hydrogen nuclei in it can be thought of as small magnets. It you put your body inside a constant magnetic field (like the one generated by the huge superconductive coil you can see in the video) they all align. Then, if you introduce a radio frequency pulse at just the right frequency (known as the resonance frequency), they start to spin around. Then, if you cut the RF pulse, the nuclei slowly align themselves back with the main field. During this process, if you have a coil next to them, you see a changing magnetic field. That signal, along with some fancy math, allow to build the images doctors use.

The last time I worked with coding was 4 years ago when I programmed a BMP interfaced game of pong in BASIC. don't ask me to remember much of anything from it, I'd need to bust out the old program again to do anything.

 

I briefly dabbled in Java and even more briefly with C++ but coding just isn't really my thing.

[Dr. Derpy Hooves Ph.D]

I used to run an RS 317 server, and that involved screwing around with a java code, if that counts for anything.

Nope. I wish. I'm not working on anything decent right now, just resurrecting a kids game that closed four years ago called CokeStudios. I don't even know why.

 

 

For those that are interested, the game is in shockwave and is kind of like Habbo. You mixed music with it to make money, or played the minigames. You spent the money on virtual furniture to make rooms etc. I really don't know why I'm bothering to bring it back. The client is annoyingly protected. It uses a really bad system for half of the connection, which I can only assume was sabotage on the part of the developers.

 

But yeah, I really have nothing better to do. I played it back in 2002/2004.

Never heard of POV-Ray before, but the animation seemed pretty neat. :3

I asked one of my clan mates to teach me LUA a bit. I managed to make a small GMOD swep, but now i forgot.

If you're interested, this might help refresh your memory.

[Vapymid]

It's been a few years since I've programmed anything other than an occasional DVD...

 

The last thing I've done - a simple game - is attached (a zipped .exe - safe, no viruses/trojans, maybe a bug or two).

 

The language used is called SiMPLE which is basically an abstraction layer for a C++ compiler.

I know my way around lua, that tutorial happened to help alot, actually. XD

 

Only problem I have with coding is small errors that screw up the entire thing.

That happens with everything, but it's always satisfying to crush them!
