My own (bad) encryption!

I was bored, and decided to use my recent knowledge of bit operations to make a super easy to hack encryption method.

Here’s the source code

It basically uses a randomly generated byte[128] array and XORs the values inside it with the string given as input. Then it XORs them again to return the original values. Not the strongest encryption, but good enough to fool someone at first glance, perhaps.

Burning sand clone r5

Added ability to toggle faucets and if the sand runs off the edge or pools at the bottom.

Learning about basic bit manipulation

I was recently interested in learning about manipulating bytes to contain flags and such, and so I did some reading, and made a very rudimentary script showing some basic knowledge of the matter.

Burning Sand Clone r4

Added ability to toggle gravity and change the brush to create different types of terrain. Also, all of the action happening in the screenshot below is at a constant 100+ frames, since any lag is based on the amount of particles being displaced, and the mound is no longer being computed.

Burning Sand Clone r3

Now, A good frame-rate will survive many things on screen, and lag is dependent on how many things are moving, instead of just static.

Improving the basic Burning Sand clone

I decided to improve upon what was there, and now the game will update much smoother, runs at around 150-300 fps uncapped, and also is a 400×300 grid with 2×2 pixels for a nicer appearance. Also, thanks to kappa from lwjgl for help with setting up the Renderer for displaying the graphics faster.

Anyways, here’s the updated source for the improved performance version of the program.

EDIT: Improved the mouse so that way it interpolates drags of the mouse for smooth lines. Changes made to the source code link above.

Burning Sand Experiment

I thought I would try making my own small tech demo of a burning sand style game, but so far I’m going to need to research something faster like VolatileImage or BufferedImage even, since right now the screen is being stored in an int array, and being drawn with fillRect().

Here’s the source code

Sphere Game r2

Here’s the updated program

Here’s the source code

Basically, updated to be slightly more entertaining! Now, you must avoid spheres of a different color than your own. You can right click to swatch out your color. The bar on the top represents the mass of black vs white spheres, and you can only gain score when playing as the minority color. So far, there aren’t any difficulty levels or levels to beat, but you *can* win if there are enough spheres on screen, just to avoid lagging. Suggest anything here! Also, if for some reason the player isn’t there when the game begins, it is because it spawns over where your mouse is when you open the program, and your mouse was off screen This is a really bad way to do it, but I am too tired to fix it tonight.

Sphere Game!

Dodge the spheres for as long as possible! A super simple game I wrote in about two hours while bored.

Tree Generator

I was thinking about procedural generation, and read an interesting post over on tigsource, and decided to make a basic tree generator, since I have basically been tackling any programming problems that are interesting to me. Here’s the result of very little work, but it’s still kind of nifty.

As usual, mt, is the Mersenne Twister. This can be swapped out for Math.random() or java.util.Random.
