LD48 Entrants

2004/11/14


I have made a number of fixes to ChompDice and I think they improve the game substantially. The difficulty is much lower now and chompie's dice pushing ability been tweaked so it should be much easier to win.

One tip to this game is to train yourself to keep a running count of the dice in your head as you play. It's actually kind of like card counting, I think, with the pressure of trying to total the dice in your head building as you desperately try to move chompie in position. At least that's what it reminds me of, not that I was really ever decent as a card counter.

Another tip is to memorize the sides of the dice, because if you push a die with 5 showing to the left, the new face will match exactly what a real dice would (assuming you are able to get the angle right). If you do this, the game should become really really easy.

So anyway, now you get a star for each game you win in a row. See how many stars you can get. My record so far is 15!

Here is the new link and web site. This is the new permanent home for the game and I will release all new versions to this site.

Don't forget to vote for the uberprize! And please, don't vote for yourself :)

2004/10/22

I've added the Linux builds of DiceMan, there's two flavours, a precompiled x86 binary release, and a source version, to make the source version simple untar change to the directory (DiceManSrc) and run make you can also use make install which will copy the game to /usr/local/games/DiceMan. You may get warning message about the last line of the source files not having carriage returns, dont worry about this, it wont stop the game compiling, and I can't be arsed fixing it, it's not a warning, it's just the compiler being overly pedantic about file format (something that a freeform language like C++ shouldn't even bother about, it's not as if it couldn't read the line).

You can download them here, along with the original windows installer.

Ludum Dare 5th 48 hour Game Development Competition
Post Mortem

Theme: "Random"
Entry name: "Blight Warrior"

Copyright 2004 Jetro Lauha
http://jet.ro


This post mortem is written a few days after the competition.

This was the third time I entered the 48 hour game dev compo. As before, I took it somewhat lightly, not taking too much stress about the whole thing. This time I also voted for the themes both first and second voting round. For the past two compos I didn't take any part in voting and didn't even check out the candidates for second round.

I feel that not contributing in voting made it easier to think up an idea for the final theme to work with. This time I felt it considerably harder to decide what idea I would concentrate on. I guess this is because I had already thought up more about ideas for a different theme from the second voting phase, which wasn't the final chosen one.

Well, after a few hours I finally settled on something I found interesting to try my hands on. It was an algorithm called "diffusion limited aggregation", heavily relying on randomness. In fact it is just bunch of dots moving through random path until they hit something. The algorithm can be used for generating certain kind of plant looking images. I read about this from the book "The Computational Beauty of Nature" (http://mitpress.mit.edu/books/FLAOH/cbnhtml/) and from a page about the algorithm in Paul Bourke's web site (http://astronomy.swin.edu.au/~pbourke/fractals/dla/]). As you can see, since I didn't have an idea which immediately felt good enough, I got a sufficient idea from spending a little bit of time for research.

Still I started by just implementing the DLA first and spending time optimizing it and adding graphical effects to it to make it look better. It took until about half of work for whole entry until I started concentrating more on game play. I borrowed the excellent Mersenne Twister pseudo random number generator algorithm from the net, which I think should be acceptable with the given theme. I could have used normal rand() as well and you wouldn't see any difference, but I thought it's better to make a bit of extra effort to find and use some better algorithm.

I didn't have practically any really bad bugs or problems hindering development. I just noticed a bit too late how much the game play would need tuning and trying out different things to make the game more enjoyable. I think at the end I got it much better than what it was at some point, but still I know there's room for improvement.

Rough estimate of total amount of actual development time is about 24 hours. Sleeping, eating, etc. are not counted in that.

What went right:

  • + Familiar set of libraries (SDL etc).
  • + Game design not needing a lot of assets.
  • + Picked an idea which was interesting to try how the DLA could be applied to a game.

What went wrong:

  • - Too much thinking before compo about other possible themes made it harder to think ideas for final theme.
  • - Didn't spend enough time for game play - should have cut some time from graphical tuning for that.

Some random stats:

  • 1 PC (3 GHz P4)
  • ~24 hours of development
  • about 77 KB of source code (3073 lines, 21 files, including the borrowed Mersenne Twister pseudo random number generator source)
  • 85 KB of graphics (9 png files)
  • 236 KB of sound and music (5 ogg & it files)
[13:15] Postmortem

Postmortem: DiceMan in The DiceMan Cometh


I started this game about 6 hours after the contest officially started, since I'm in the UK and the contest started at 3am, I was in bed at the time, fitfully trying to get some sleep, I got up and was ready to start at 9am BST. That's when I found out the theme was Random, and it was time to spring into action.

What Went Right:

  • Having some idea of what I would do for each of the Themes was extremely handy, the only one I didn't have an idea about was 1 button which is why I'm glad it didn't win.
  • Using SDL. I'd used SDL in my FireTrack remake that's still in development and knew that I could quickly get something running and onscreen.
  • Encapsulating SDL_Surface in a BMP structure, using my own structure instead of SDL_Surface allowed me to write the Renderer much faster since I wasn't having to deal with setting and changing SDL_Rect's all the time.
  • Spending the time on writing my own font system. I had originally looked on the net, but couldn't find one that would be easy to use, so I had to write my own.
  • Adding little touches to the title screens, like the particles on actions, or the scrolling letters. The particles started when I added particles to the name entry screen when you entered a character, and realised that I could use it elsewhere.
  • I ended up with a solid SDL framework that I can use to build other games with.

What Went Wrong:

  • Changing Idea part was through the contest. Although the game name and graphics didn't change, I realised about 12hrs in the the game as it stood just wouldn't work (it was a single screen and the dice rolls added/removed one of 36 platforms on a 6x6 grid), so I redesigned it as a platform game which opened up the gameplay and allowed me to start making major progress.
  • The Font, although it's great on the title and the bigger font, it just didn't work for the smaller font, I should have used a simpler font for it, something that's easier to read.
  • Levels, I really wish I could have designed more levels, I ended up with 5 (4 + 1 vanity level) I just couldn't make levels that were either extremely easy, or almost physically impossible. Using Mappy with .MAP files is a pain since you have to specify the block size and tileset every time you reload one, so it made changing and testing the levels harder. Next time I'll concider writing a simple level editor, it would have made things far simpler.

Afterwards:

Yesterday I spent about an hour porting my game to the PS2 Linux kit, it ran really slowly, but I've fixed that now, and while not as fast as the PC version it's still pretty respectable, I'll release a linux source version soon, and possibly some pre-built versions including a PS2 linux version.

I'm looking at taking this framework and producing a real game, I've got an idea for a game and feel that with the code I already have I could make a really good game.

Seeing how everyone was posting one of these, I'll go with the flow.

How I got the idea
Initially I was pretty dissappointed with the theme, seeing how out of the 5 themes the only theme I couldn't really get an idea for was chosen. But I sat down for about an hour, chatted on IRC here and there, and suddenly got this neat idea.

What went right
During the development I think my best decision was to keep the game simple first, and once it was done and playable add more and more elements. This ensured I would have a game ready within the alloted timeframe and hopefully without too much bugs.

What went wrong
I spend too much time trying to make some sounds which I ended up deleting because they broke the rules. (Used drums and stuff which I distorted into explosion and gunshot sounds.) I could have much better spend this time on fixing some bugs.

For the future
Try and get more sleep before the competition, and no organizing any LAN parties afterwards. I was wasted. :D

Extra
I fixed a few bugs in the game after the LAN party, now, I know it wont count for the competition, but for anyone who would like a slightly more debugged version, http://deepflame.deeplyswitched.com/files/games/Tanks.zip should provide just what you're looking for. (It still contains various bugs, like, anything that manipulates it's window in any way will cause the game to freeze and/or crash.)

All in all, I had a really great time writing this game, and playing all the other games. There's some really neat stuff out there! :)

[04:52] .NET

Someone posted a comment in reviewing my entry - that they couldn't run the game. Could you please make sure you install .NET 1.1 before trying it ? You can download it from Microsoft If that doesn't work, then i have no idea - and not knowing who posted the comment, i cant help. We probably need a way for entrants to respond to judge's comments other than the diary pages.

[23:03] We cheated

We were two ppl working on SokoBomb.

Here is my accessory elAk's diary (was removed from entrants)

I've managed to produce win32 standalone executables. I throw myself on the mercy of the judges.

Eaters Of Coins for Win32

Of the game itself: I was lazy and made the first thing that came to mind and only put a minimal effort into making it really exciting. Given that it was what I had intended it to be. The basic concept: boring, easy, unoriginal. Spit out a bad guy every frame, shoot a bullet every two frames. Plus special weapons: moderately fun.

Had I been more motivated/inspired: I would have made a 1st-person maze game that tried to creep you out. Or maybe a 2d one...

Of the competition: Good job to most of ya :) There were many good entries this time around.

2004/10/18

Overall, this competition went much better than last time. I credit a better understanding of what's possible in 48 hours, and a slightly lower expectation in the graphics department. Tools used:

  • Pygame (Python & SDL),
  • Vim for editing the code,
  • RCS for making sure I had working snapshots along the way,
  • The GIMP for graphics (I still don't know how to fill a transparent region ;), and
  • Audacity for recording sound, even though I didn't end up using any of it.

What went wrong
I switched "theme" mid-stream (from zombies to ducks). This allowed me to use better graphics, but also meant that the sounds I'd recorded were useless.

I also spent a large portion of Sunday morning (at least 3 or 4 hours) integrating tile-based map drawing code and debugging it. I really should have started with the tile-based drawing in the first place. If I hadn't lost those hours, I could have added more items to pick up, more objectives or even sound.

In the sound department, I still have a fair bit to learn. When played in the game, the sounds I recorded for the zombies ended up all crackly. I believe that's to do with the sampling rate and the rate the SDL sound mixer wants (it's a bad re-sampler).

What went right
Well, I ended up with a playable game. It was based on a boardgame called "Zombies", but the game I ended up with deviates in many ways from the boardgame.

My adherence to the theme was very strict. There's very little about the game that's not random. I have a ton of ideas about more random stuff to throw in, but alas... :)

In all, I timed the development pretty well - though it was mostly about not spending too much time on any one thing (except that bloody map code ;) and making sure I was "finished" at least a couple of hours before the deadline so I could test packaging and make sure there weren't any problems on Windows.

On a more personal note, the comp reminded me why I got into this programming gig in the first place - sometimes it can be incredibly fun and rewarding.

To remember for next time
Don't choose a game style that relies on hand-drawn art - I simply can't do it :)

I have to haul back on the expectations a little more. If you can get away with having your game on one screen (thus eliminating icky scrolling issues and mini-maps for navigation) then do it. There was really no reason for my entry to have a scrolling map.


Here is the game online if you just want to try it without downloading it. In the future I may continue to update this online version. There's a bunch of things I want to fix in it, including some annoyances that keep the game from being as fun as it could have been.

Play ChompDice Online

I must say upon looking back that I learned a ton during this experience. My game creating skills were completely rusty and it was difficult even to remember how to code basic Actionscript. And what a pain in the ass language it is!

Anyway, great competition. Thanks Richard!

[12:15] Post-mortem

I've written a Post-Mortem for my entry Ring48. I hope I'll see post-mortems for the other games too.

[20:25] Done (kinda :)

Well, I've finished what I can. Unfortunately there's no gameplay. :( The "game" will currently create a random level with semi-intelligent cars that travel a random route.

The intention was for the player to be able to control stoplights at the intersections and try to (a) run a nice, orderly system, or (more likely) (b) cause insane amounts of mayhem (a la The Italian Job). :)

I hope to continue this project so I'll keep you guys updated if a more fully-realized version gets finished.

I've managed to finish something and I think it's even playable. :)

Ok, I can't upload for some reason. It says overquota. But I'm putting the file up on my own site. This is the final version and will not be touched. chompdice flash files (zipped)

(source)
This is about as done as I can get it.... I managed to add a little bit of polish by the end but there's a whole lot of detail that I wanted in the game but didn't have time to add... If I hadn't wasted hours on collision detection and angle calculations, I might've done more. By next time I'll have to read up on quaternions. (or stick to a 2D game)

Gameplay: You have to fly random missions in random dungeons, fighting against random enemies to achieve a random goal! :D You can see your objective at the beginning of every mission. Navigating in full 3D can be a bit confusing, also, controls default to invert_mouse = on and I forgot to add a way to change that, sorry to those who are used to different 3D controls.

Missions: The three type of missions are: Kill everybody, Kill a boss, and Fetch an item. I think they speak for themselves.

Controls: Mouselook, ASDW strafe and "fly" like in any FPS, and you can fly up or down with RF. Fire with space or the mouse button.

Enemies: Kill them before they kill you. Be careful about getting into big firefights. The AI is dumb but it has the power of aiming by vector calculations, so if you don't dodge, you're toast.

Items: White is health, black is a better weapon. Purple is the Exit on missions where you need to fetch the Blue item. :)

[20:04] Final Game

It's done! needs a LOT more content, but it turned out really well.
Check it out: ButtonLands.zip (1.07 MB)

[19:59] Encaved
[19:59] Done.

It's not much, but it's a game. I'm happy with it. My first action game, my first perl game, and my first SDL game.

Unfortunately it needs Perl and perlSDL to run. No executables.

I present:

[19:55] FINISHED@!!

I am finished. Had a problem uploading. Am reuploading. Just the executable files. The project is too big to upload here.

WHOOOA!!

[19:47] Final entry


Download SokoBomb! 2.9MB now! (Includes source)

Plot: There is a random evil plague at a random facility. Can you complete the random task through the random rooms, filled with random boxes that some random robot has randomly placed in the random room. You might encounter some randomy guy. And yes, the game is endless, you can stop playing at level 492.

Edit: Known bugs:
Player gets Invisible when hitting space
Can only handle one bubble, causing them to appear buggy
Bubbles is out of screen sometime
Exitrooms startdoor is faulty
If stuck in first room on a level, there is no way to reset the room, you'll have to selfDestruct
Readme says that gamepad control is possible, this is wrong, I took it out before the deadline (To prevent possible bugs)

[19:31] Finished

Wahuuuu... Everything got finished in time and I have... at least got a game. You can download the windows-executable here and the source here.
Screenshots:

[19:28] Finally

Phew. That's it. My final submission for this contest.

ZIP-Archive containing Win32 executable, necessary DLLs and source code

Yeah, got some bugfixes in and some more polish (like animations and flying bullets :). Get the latest version here (.NET).

[19:17] Final version
Controls and gameplay:
- Arrows to move, space to jump.
- Dodge bright flux which saps your health.
- Shoot matter particles to create dark flux, which regenerates your health.
- Zones only last a few short waves, see how many you can survive for!

Play via webstart (fullscreen) or play windowed.

Should work on windows and linux platforms, tested on windows. Requires Java 1.4 or later, OpenGL 1.1 or later, and uses LWJGL and SPGL.

Webstart notes:
If you've got Java 1.4 or later installed, you will already have Webstart installed and configured. Simply click the link and open the file to start the game. If you've not got that, go download it from Java.com

- Webstart has a tendancy to pop up dialogs under every other window. If the download window looks stuck, theres probably a dialog hiding under one of your other windows.
- Please don't worry about the security warning. Thats just because I don't have a spare couple of hundred quid for a security certificate.
- If 'enter' doesn't start the game then click the mouse once to let it grab the focus.

Download either the source (smaller, requires pygame) ld48-ducks-src.zip or ld48-ducks.zip.

Click here to download Tanks! 2.33MB

There it is people, about 35 hours of work (Slept 10 hours and wasted 3 hours walking around and stuff :P) presents one game. :)
I'm quite happy how it turned out.

The readme.htm lists all the commands, but the ingame tutorial goes through the basics too.
Have fun!

[18:54] Finished!

Trouble Shooter is complete and ready for your playing pleasure!
Zip file (requires Python and Pygame)
Windows installer (standalone, includes source code too)

At the risk of sounding biased: It's fun.

Stuff to be (maybe) added post-competition: Saving/loading game, ramp up difficulty, boss monsters, experience points, shopping for equipment, another ingame tune.

[18:34] Final entry?

I seem to have run out of ideas to add, so I guess I'm pretty much finished. :)

I was thinking of different matter types, or pick up items, but they would have distrcted from the game I was trying to make so they got shelved.



Also added scores and some last minute polish on the help text. Endless tweekage of speeds, jump height, flux wave randomness, etc.
Click to start

Okay, that's it, it's time for a cup of tea and a to bed, so here's the release version of DiceMan in The DiceMan Cometh, my first LD48 competition entry. I've had great fun doing this, even managed to get a decent nights sleep last night (much to my surprise, since Friday night was hell, I hardly slept at all).

Anyways, grab the final version HERE.

or you can download the .ZIP non-installer version HERE

Almost done, just a few details to get ready to release it

woo feature complete finally.. you can actually win (or lose) the game. Now I just need to make more heros and enemies so that it's not the same thing every time. no time for screenshots...

Phew! Looked like I was gonna fail but here it is! The first playable game can be found here. It still lacks some polish & sounds, but the gameplay should be complete. Couldn't test with other humans yet since they're all asleep :). I might make some updates still, yay!

[18:07] Final Entry

The game is now as complete as it is gonna get. There are now sound effects and different maze tiles. You can download the executable, code, and data here. When unzipping preserve directories, it won't work if the data directory is not created in the folder under the executable. You need to run it from the same directory as the executable too. Hopefully it is fun, considering the time constraints, I think it is pretty good.



2004/10/17
[17:59] All Done

Done and submitted.

Why did net connection decide that this weekend would be a good time to stop working? It's been spotty all competition, except hasn't worked at all since this morning. Fortunatly I could get access elsewhere; I'd be supremely bitter otherwise :). Time to call the cable company . . .

[17:58] Done and done.

Well I think thats me done for now.. unless anyone points out something really horrid.
Here

It's ready and here it is:
Blight Warrior 1.0.0 (Win32 binaries)
I'll probably try to write some post mortem text next week.
And here's the sources. Be sure to download the binaries zip also.

[17:47] Menus Working

All I need to now is to Add the story, winning, and Changes keys screens and maby one tune.

The first Release Candidate of my Game DiceMan in The DiceMan Cometh is ready for testing, it's an NSIS windows installer it will create a shortcut in the start menu called 'DiceMan'

You can snag a copy here.

[17:38] It's done!

The game is ready for submission! I will post it very soon now.. :)

Yes, here's the new secret: the zombies aren't zombies, they're DUCKS! Also, you can pick stuff up which gives you bonuses:

I'm so very, very tired right now.. and it's only 01:30 (am). But I'm ready! Or at least as ready as I'm going to get. The game is called Random Dungeon Exploring and you can get the final entry right here (win exe + src). I don't think it requires anything much, but a card supporting OpenGL at least. Compiling it for another os shouldn't be a problem if you have Allegro & AllegroGl.

The game may seem a bit hard just in the beginning, but when you've found some items, or gain a level, it gets easier!

It ended up with just below 60 KiB source code which is quite much, it's at least more then I've ended up with in the previous LD48s. But this time there's no sound, so maybe it evens out. Anyway, have fun with the game! I look forward to test all the other entries, some of them look really good :)

There at last.
But it was worth it.
The world is now made richer by the presence of pyBalloon 1.0

Download Windows binary with source 1.7MB
or just the source if you have python and pygame installed on your system 192kB

I look forward to the marathon of game-playing that will constitute judging - Good Night

[16:51] Finished!

Everything done! Have Fun!
download here or here

Im sorry people im not going to enter my entry coz its not finish and i cant finish it :( sorry :( and my stumik kills me ohhh no more cola for me :F good luck every one ill stick around see what your doing :P

[16:49] Final touches

Added "Level Done" & "Game Over" screens. I will probably wrap it up and call it finished quite soon now, just have to test it a bit more. Didn't have enough time to tune gameplay and add some additional fancy features, but it's still not bad I think. :)

[16:44] Tanks! - Done!

Welp, the game is all done. Now I'm going to spend 3 hours writing a readme.txt and spending time playtesting until my brain comes out.

Okay the cars are set... every thing works fine... the Ai works fine as well...every thing is random :P damn i dont have anoth time...and im hungry *goes to have a snack* ok i have playerVScom soon ill put 2 players maybe but most defently ill put another com... :) no pics now sorry im out of time :(

target bug, Text bug, Reving Story to Require 4,000 KW insted of 100,000 KW

[16:15] Done!

To get the executable version go here. To get the source version go here. Note that the executable version extracts to a new folder for you, but the source version does not. (lazy)



Ouch. I might just be able to finish this.

Woo Hoo. I think this qualifies as a game now. I even have a title screen and some trimmings (pause and such). I would like to add sound effects, and maybe some more background tiles so it doesn't look the same every level. Other than that and packaging everything up into a zip file with a readme, I think I am done.



[16:06] Got it!

I had been mispelling "Arial" all this time :D Don't know if it'll work OK in Linux or elsewhere but it should be fine in win32. I will put up the downloads and another screenshot shortly.

[15:57] Argh

py2exe is being mean...some problem with using sysfonts.
