Genetic Algorithms Lab

Genetic Lab

 

So a few years ago I did a project for the Genetic Algorithms assignment at college. My idea was to have tiny multi-cell organisms that have a simple goal: travel as far as possible! maybe to find new resources or escape from predators, you pick one 🙂
So the fitness of a creature is measured by how far it can go during its life span.

The creatures will start with random moving cells and evolve to more organized creatures with organized movements.

Please watch the video before reading. If the video failed to make you interested then I doubt that the text would succeed. You can also download the executable and the source code available at the end of this post.

Simple Spring Physics

02/03/2013 8 comments

A few weeks ago (during exams period 😛 ) I was playing with spring physics, it turned out to be easy to implement and the results were cool enough for me to write a demo in Android, Microsoft XNA, and Javascript :D.

Before I talk too much, here see the results for yourself, this is the web version :  SpringLab Web Version.

Reminds you of World of Goo 😀 ?

I came across this tutorial, from which I learned this lovely vector equation:

 F = -k(|x|-d)(x/|x|) - bv

I applied it to 2D springs and it gave amazing results especially when Read more…

Hex Screen

Intro:

Hello, it’s been more than three months since my last post, it’s also been more than three months since I last opened Visual Studio :(. A few days ago I decided that I should write something with XNA, that’s when I decided to write Hex Screen :D.

Hex Screen?

Hex screen is a 3D screen made up from hexagons, the cool thing about this screen is that hexagons can be animated to give nice effects, hexagons can be rotated, moved and scaled.

A screen made up of 42*20 Hexagons

FuchsGUI Update

09/08/2011 Leave a comment

Hello there, sorry for being inactive lately but I don’t feel like programming or learning something new :(.

Anyway, I fixed the issue in FuchsGUI where some text was blurry, the reason was that the text was being rendered with floating point values for position, something like (20.3f,29.4), this meant that spriteBatch should split physical pixels :(.

Anyway, thanks to a guy named Fab who told me how to fix this, the solution was something like this:

position.X = (int)Position.X;
position.Y = (int)Position.Y;
// Render here

So, here’s the fixed version (XNA4 only):

   FuchsGUI v1.1 Source Bin XNA4 (Blurry Text Fixed)

I hope to see you later :)…

RobotWarz Alpha Release

RobotWarz

Introduction (a boring one maybe 😉 ?)

Good morning\evening or whatever suites your timezone :).
I’ve been waiting for this :D!, I’ve finished programming the alpha release of the game.
The reason I’m publishing it right now is because It might take me some time to have a full game, so by publishing an alpha release I can get opinions & suggestions from people which will encourage me to complete the game.

This release isn’t meant for end-users but rather for fellow programmers.

Unfortunately my laptop doesn’t have a graphics card so Read more…

It’s been more than a month since my last post, I didn’t run out of ideas yet! but I’m really busy with college & its projects :(.

One of the projects I’m working on is a game for a Graphics project. it’s a third person shooter game, you can watch this short video to get an idea about the game 😀






Stuff to share later when I get the time to:

Gray Fox – Space Defender: Silver Winner (and yes my nickname was Gray Fox before moving permanently to Fuchs 😀 )

Vmpwje – Block Invaders: Gold Winner

XNA Fuchs InputHandler

22/03/2011 2 comments


Introduction:

Each XNA “Game” I program I have to take input, something like the following


KeyboardState prevKeyboardState;

protected override void Update(GameTime gameTime)
{
    KeyboardState keyboardState = Keyboard.GetState();

    if (keyboardState.IsKeyDown(Keys.Left) && prevKeyboardState.IsKeyUp(Keys.Left))
    {
        // Do stuff
    }

    prevKeyboardState = keyboardState;
}

I have to create two KeyboardStates, one for this frame & the other is for the previous frame. Then in most cases I check that some button is pressed only in a frame not in its predecessor…( because even if you press a button and remove your finger quickly the, button will be considered pressed in more than one frame )

Same issue goes for the mouse.

So I thought I should create my own input handler, Read more…
