cuckvid released!

Because other codecs take too many clocks.

But they also tend to look better

 

Source code is here: https://github.com/iamgreaser/cuckvid

Could be useful for people making games for weird platforms. It should have enough grunt to run nicely on a Raspberry Pi for 640×480 @ 30fps – who knows. (But then you’d ultimately want to use OpenMAX and the H.264 decoder.)

Anyway, now that I’ve declared this code I might end up using it. Or maybe not. Do I really need video? I have a program loader and hardware sprite transforms at my disposal. Who knows.

Live Free Or I’m In

I’m in.

I’ll be making a game for the Game Boy Advance.

It’s a piece of hardware that’s capable of doing stuff like THIS:

WIP shot of an Armagetron Advance demakeLD32 Warmup Indev shotMiniLD #58 entry

I also proved it was possible to poorly encode the entirety of Too Many Cooks @ the full 24fps in under 32MB. (It can only decode 40% of a frame every vblank.)

Oh, and the usual list:

  • Languages: C, Python (for table generation and format wrangling and crap like that)
  • Libraries: f3m, libgcc for embedded ARM (if I need a libc function I’ll roll it myself)
  • Music: SchismTracker, Scream Tracker 3, possibly SunVox
  • Samples: Audacity, SunVox
  • Graphics: pixra, GIMP

There’s a chance I’ll be using my ADPCM decoder, which is here: https://gist.github.com/iamgreaser/967070e7f02108b87003

I doubt I’ll use the mode7 engine in there, though.

But anyway, as they say, it’s on like Sonic the Hedgehog.

 

Mini LD #58 Theme Interpretation

Pinball.

I cannot be shafted writing an AI, and I really don’t feel like redoing Breakout.

What Pinball has:

  • Balls! Yes, that’s right, you can have several at once because just about everything that Williams did has some form of multiball! [citation needed]
  • Bats! Except they’re nailed to the board and can only rotate into one of two configurations.
  • Ability to lose!
  • Score!

What Pinball doesn’t have:

  • Ability to win!

What my platform has:

  • Sprite rotation!
  • “Playfield” rotation!
  • Scanline DMA to hardware registers!

Main thing about this is unlike making Pong (which I pulled off on the Atari 2600 once… only to have someone tell me that the picture rolls on real hardware), this will be an artistic challenge.

But enough procrastination, time to get some *.tga making and loading action happening!

(What? I have 16MB of ROM space to kill…)

Oh, and of course I had to make some music first.

I’m in with a vengeance

(Nobody used that title? SHAME ON YOU.)

No, this is not my third LD, it’s probably about my 6th although that’s mostly an estimate.

I’ll be warming up and refining my tools during MiniLD #58, so I can then get ready to beat everyone’s arses to a pulp in LD #32. Namely, I have a nice S3M player which needs work in a few places.

Speaking of MiniLD, sorry for missing MiniLD #57, I was working on another game at the time.

So here’s my setup:

  • Languages: C, dash of ARM assembly (for bootstrapping), Python (for conversion scripts and whatnot)
  • Libraries: f3m (will be updating this as I go)
  • Editor: VIM
  • Graphics: pixra, GIMP
  • Music: Schism Tracker, Scream Tracker 3
  • Sound: Audacity
  • Engine:  ENGINES ARE FOR THE WEAK

And that pretty much concludes my setup, other than the fact that I haven’t mentioned what my target platform is, so I’ll leave that up to you to guess, although if you’ve been paying attention in #ludumdare you’ll know already.

Might be in?

If I’m doing this there’s a chance I’ll be teaming up with someone. And to be blunt I’m not sure what we’ll be using.

Here’s my bag of tricks anyway. It might be something completely different, but there’s a fair chance just about everything I use will be here…

  • Languages: C, Python, Lua, C++, JavaScript, Ruby, whatever MegaZeux uses, maybe even GML (Game Maker 4.2a)
  • Libraries: Allegro 4 & 5, SDL 1.2 & 2, OpenGL + GLEW, libsackit, ezjack
  • Music: SunVox, SchismTracker, various converters, custom playroutines
  • Sound: Audacity, SunVox
  • Graphics: pixra, GIMP, Blender, code-generated stuff, converters I pull out of my arse
  • Level editor: Probably just VIM
  • Networking: ENet

No, I’m probably not going to use assembly this time.

I’m considering making a 3D game with red-cyan anaglyph support. This still leaves things pretty open-ended.

It’ll most likely be C++, SDL, OpenGL+GLEW, and the rest is to be decided.

Change of plan.

Y’know how I said I was going to be doing the compo using C + Allegro?

Change of plan. I’ll be jamming with someone and using PyGame.

Will probably be laying out the foundations of the engine as well as making seriously smooth sounds and gorgeously grotesque craphics.

…once I’ve got pygame working, which is currently depending on numpy, which seems to be missing a few files.

(en: “I am causing a great disaster”)

Well, I needed something more interesting than just “I’m in!”, so I thought I’d have a bit of fun with that. I think “.i mi zvati” would be the best translation.

About 4 years ago, LD #18 happened, and I participated in my first Ludum Dare. Somehow I ended up in 1st place for audio. I made the game using Java + Swing… on FreeBSD. No, that’s not the name of a Linux distro. It’s actually a different OS (which ends up sharing about 90% of the average Linux userland anyway).

This time around, I’m using FreeBSD again. But I’ll be using something I used before I ever touched Java. That’s right, Allegro 4. I used that for LD #21 (“Escape”), and it was quite frankly a breeze to work with. That time around I used dumb to play my music. This time I’ll use sackit.

So, here’s the lowdown.

  • IDE: VIM
  • Languages: C, possibly Lua (but probably not)
  • Compilers: Clang (native FreeBSD), MinGW (Windows port), GCC (Linux + Raspi ports)
  • Libraries: Allegro 4, sackit
  • Audio: Audacity, SunVox, SchismTracker

I’ll probably be using Allegro 4 for what it’s good for, rather than writing that hackjob partial Sega Master System emulator I did in LD #18 (Never. Again.), so we’re talking maybe 2D vector graphics and stuff like that.

So yeah, with all that crap said, I’m in!

World editor!

Currently there’s only 3 terrain types and they’re graphically boring right now.

You rock

But I can make them look more interesting.

OK, so the collision detection is kinda shit and there’s no enemies yet. I might as well focus on adding them.

World editor now working sort of

Let’s just leave a screenshot. (Also, all the screaming about bugs in the OpenGL implementation? They were all my fault. I think.)

I can breathe.

…ok, I still don’t have an actual game yet. But the character can breathe.

…I need to sort my priorities out.

Anyway, little tech demo – move the mouse around and the eyes will follow.

Working on some music.

Whipped up some samples in SunVox and started work on a simple loop. The samples pack quite well.

It’s just the “chorus” section, so to speak. The bass didn’t come out very bassy though so I’ll need to chuck in some subbass, but it’s an FM bass so it’s still inherently awesome.

And my battery is running low. Should be home soon.

JACK support!

Posted by
Saturday, December 14th, 2013 2:12 pm

I’ve added JACK support to my game, because SDL2 doesn’t have a JACK driver and Fuck You PulseAudio.

It acts as a wrapper around the SDL audio callback I wrote, and calls it whenever it needs a new buffer.

Took under an hour.

I’m in a van.

Text boxes! (6h in)

They’re even a self-contained “class”. And they’re rounded, too!

Certainly not!

I think I’ll take a break from this now.

5 hours in and I have part of a face

So this is where I go all artsy and focus on making my game look good.

As some of you already know, this is highly unlike me.

awwwww

Note, my internet at the moment isn’t amazing, so don’t expect me to linger too much.

Base code “complete” (Boilerplate 28)

Posted by
Friday, December 13th, 2013 1:36 am

Because it hasn’t changed graphically, I’m just going to reuse this screenshot…

recycling is good

So what has changed?

  • It has sound!
  • It has music! (.it music, to be precise)
  • I probably fixed a few bugs along the way.

So the links:

Expect the graphical style of my game to be similar to that screenshot.

So yeah, once more from the top…

  • Language: Primarily Lua, but I might have to screw with my base engine, which is coded in C.
  • Text Editor: VIM. What, you seriously think that anything else is even remotely worth using? (Important note: Sublime Text is in the “anything else” category.)
  • Base Libraries: SDL2, linmath.h (bundled), base engine (“Boilerplate 28″).
  • Craphics: OpenGL + a modified version of the PNG loader I made for seabase (which unlike Firefox’s PNG loader completely ignores the sRGB tag, so your blues won’t become purples). If I need more PNGs made, I’ll use GIMP. The graphics will be manually bashed in with Lua.
  • Sounds: A custom mixer. I’ll probably do vocal samples in Audacity.
  • Music: libsackit (bundled). Music will be written with SchismTracker. Might make some samples in SunVox. Will probably end up using ST-xx samples and/or mzxpack.

Anyhow, consider me ready for this.

Declaration of what’s actually in my base code

So far on the Lua side I have support for:

  • glClearColor; glClear
  • Matrices + manipulation + loading them into OpenGL (projection, modelview – no texture matrix and not sure if I’ll add it)
  • Definition + flat-colour rendering of vertex arrays (of any GL_ type)
  • Loading + power-of-two-extending + rendering of 32bpp RGBA PNGs (any rectangular region – if you want it rotated, use a matrix)

There is no depth buffer support right now. There’s also no stencil buffer support yet, but I’m hoping to add support for that… there will probably be no depth buffer support, though. VBOs might happen, but don’t hold your breath.

The engine requires OpenGL 1.1, which means that it will probably run on your pile-of-crap GMA 3150. Amusingly enough, it also runs at a reasonable framerate with Mesa swrast (LIBGL_ALWAYS_SOFTWARE=”yes”).

This used to spam stars and say “You’re a STAR!” but evilbetty wanted lollipops so here you go…

that doesn't even make sense D:
