Ants

Got carried away reading about cellular autonama so I decided to make my own ant farm.

It works in Firefox and uses the HTML5 canvas so in theory it should work on any HTML5 enabled browser.

Enjoy!

ants.html

Basically it generates a couple of ants with a random set of 8 genes which dictates what color the underlying pixel will turn into, and how the ant will move to the next pixel, depending on what color the current pixel is.

Click Zap to mutate an ant, and Kill to restart an ant in a new place with completely random genes.

The eight genes are sets of three numbers each; Activation color, New color, Action. If a gene is "641" then this means that if the ant steps on a pixel with color 6, then it will turn that pixel into color 4, and turn right.

Action codes; 0=forward, 1=turn right, 2=turn left, 3=reverse.

For example, the gene set of 022,152,201,372,440,562,620,721, which was generated randomly by the program, turned out to be Langton's Ant:

Since JavaScript is very hackable, here's the code to make one of the ants into Langton's ant:

javascript:a[0].g1=[2,5,0,7,4,6,2,2]; a[0].g2=[2,2,1,2,0,2,0,1]; a[0].x=400; a[0].y=300; updategenes(0);

Just copy-paste into the browsers address bar and press Return while the program is running. You may need to tweak the a[0].x, and a[0].y parts to place the ant in an empty spot so it won't tangle up with other ants.

Update

Updated the ant program so it's not limited to a fixed number of ants or genes.

I don't know if that name is taken or whatever, but I put together a small browser based JavaScript space shoot-em-up.

Really crappy controls. Sorry about that.

Here's a live version: http://www.waxjism.org/nail/stuff/webspace/

And here's the source: webspace.tar.gz

And here are some graphics from the game:

BugHunt

2010-01-17 09:29 by Nailbar
Being stuck with no Internet access and nothing but a fresh Windows Installation made me do the only logica thing I could think of; Program a JavaScript game in Notepad.

So here I present to you BugHunt!

bughunt.html

Or BLEH!, as it was initially called.

It's not standards compliant. I don't know if it works in anything other than Firefox 3.5.5 for Windows XP. It's just something quick and simple I had to make to calm down.

Plenty of fun

I found my stash! With that I'm referring to my old website and all the random games I've posted there. This is from the time when I had a lot more time on my hands, and was just learning all these new programming languages.

Here's a list of what I've found. These are all windows programs (works in XP, I just checked) but should work well in Wine too (only the 3D programs worked but if you get the right dll the VisualBasic progs should work too).

• Hunt102.zip
  This is a compiled QBasic game where you do your best to evade the evil dots that follow you.
• bsim3d.zip
  This is one of the best things I've done in 3D; a truck driving simulator where you drive a truck, including a trailer, over a randomly generated landscape. I don't remember all the keys but at least I know you use the arrow keys to move the truck, and V to change camera mode. Then there are some keys for regenerating, or modifiyng the terrain too.
• fig017.zip
  Despite the file name this program is called Fighter III. You drive a space ship and fight against waves of enemy fighters. This game features an increasing tech level so you don't have to use the same ship all the time. Press F1 for in-game help.
• life.exe
  This is some kind of simple prey-predator game of life, made in Visual Basic. You can click on the world window in order to add predators (left mouse button), and prey (right mouse button).
• linakrak.exe
  Another simple program made in Visual Basic. Click on the screen with the mouse button in order to regenerate the world. The creatures will dig and create borders between colonies.
• nwn914.zip
  Space Figher aka Fighter I. This is the original space duel game in C++ upon which all my other space duel games are based on (like Red Roids and Miniduel). It's in black and white because I didn't know how to use colors back then.
• rro026.zip
  Red Roids 0.26. This is a later game based on the Fighter series. This one features a level editor and a story line! The physics are kinda diffult, though.
• rro105.zip
  Red Roids 1.05. This is almost identical to Red Roids 0.26 but is more complete. I think the story even has an ending.
• rro106.zip
• This is where I lost interest in developing Red Roids 1. This version is missing the readme.txt, or whatever it may be called, so you'll have to grab that from rro105.zip. The reason I packaged and posted this is that this one features a ship editor too. Here are the screen shots...
  
• rro222.zip
  Um... Yeah. This is my attempt at making a strategy game based on the Red Roids world. I lost interest after a while so it's not really finished. You just spawn there with your base and a bunch of ships. Then you produce more ships and attack all the enemy bases and they respawn and you keep doing this until your base is destroyed. There is a hud, though. The screen shots are from older versions without the hud.
  
• snake.zip
  This is something like a screen saver. You just start it, and after a while some patterns start to appear. Made this in Visual Basic.
• snakers.zip
  This is a two player snake game. One of my first programs that I made in C++. A snakes goal would be to eat boxes and grow bigger while avoiding the other snakes tail. Both snakes can be controlled by human or AI players.
• snaketrail.2a2.zip
  Basically the same thing as snake.zip, but this is done in C++ and may look and perform better.
• spacebattle.exe
  Really simple space battle simulator where all you can do is click on the screen to add new mother ships. The AI takes care of the rest. Kinda like a screen saver. Made it in Visual Basic.
• stars.exe
  Some kind of galaxy simulator in Visual Basic. All I remember is that you klick on the screen with the mouse to create a world, Return replays the world in fast forward, Space centers on the current star, Arrow keys moves the camera, Plus and Minus Zooms the camera, and Page up and Page down selects next and previous star.
• tnks205.exe
  A simple one player tank battle game I made in Visual Basic. You move your tank using the arrow keys and shoot with the left mouse button. Kill all enemy tanks and the next wave will come after you stop moving around.
• tunnel010.zip
  This is my first attempt on making a First Person Shooter. I ended up with a random-world-generator and nothing else. Still interesting, though.
  

There were also some non-compiled QBasic games which I will not post at this moment. Maybe I'll package them with the QBasic intrepreter, or as compiled... Or maybe just the code if anyone requests it.

YouTube double size

2009-02-28 19:02 by Nailbar
For some annoying reason my browser crashes when I try to watch YouTube videos in fullscreen. Perhaps it's just some bug in the Linux version of the flash player, or something like that. My screen is big enough to make the default YouTube window too small so I've added this page: [youtube.html] for playing the videos at a double size. Yeay!

You'll need the video code (http://www.youtube.com/watch?v=IRQoAcsIdj0) marked here in bold.

Just copy this code to the browsers address bar and press Return. If it complains about pop-ups, just select allow, refresh the page, and run the script again. You will get the twenty first images as pop-up windows, or in Firefox' case, new tabs.

javascript:if(list){ for(var i=pops+19;i>=pops;i--) if(list[i]) var temp=window.open(list[i]); var temp=pops+=20; }else{ var list=new Array(); var pops=0; var traceit=function(elmnt){ if(elmnt.tagName=="A"){ var temp=elmnt.href; var type=temp.substr(temp.length-4); for(var i=0;i<list.length;i++) if(list[i]==temp) temp=""; if(temp && (type==".jpg" || type==".png" || type==".gif" || type==".JPG" || type==".PNG" || type==".GIF")) list[list.length]=temp; } for(var i=0;i<elmnt.childNodes.length;i++) traceit(elmnt.childNodes[i]); }; traceit(document.body); for(var i=pops+19;i>=pops;i--) if(list[i]) var temp=window.open(list[i]); var temp=pops+=20; }

Run the code again to get the next 20 images.
