Site Update

It has been I long time since I last updated this site. For various reasons, I did not have the time to provide updates. After a while, this lead to a general loss in motivation. I have come to the realization that I will never complete enough tutorials to finish an entire game engine.

That is, however, no reason not to continue posting useful information. Over the next few weeks, I will be updating the previous tutorials so that they are stand-alone. Those should be more useful in the long run anyways. I will also begin posting some material on my new project, Galaxy Tactics.

GJK Algorithm Demo

The Gilbert-Johnson-Keerthi (GJK) algorithm is a method that can be used to find the minimum distance between two convex objects. The algorithm is often used for 3D collision detection in video games. I decided to write up a 2D implementation to try it out. So far, I have been very happy with the results. I am now planning on replacing the existing collision detection in the Entropy Engine (line-line intersection testing), with the GJK algorithm. I will also write a tutorial on the algorithm in the next week or so. In the mean time, you can see it in action here.

Game Engine Design  SVN

I have set up a SVN repository at Sourceforge.net. If you have an SVN client installed (such as TortoiseSVN), you can check out a copy of the current game engine code. The repository location is https://entropyengine.svn.sourceforge.net/svnroot/entropyengine/trunk/entropyengine. I will also be packaging various releases to go along with the tutorials, so if you dont want to use SVN you can simply download a .zip file. A word of warning, the game engine is still in early development and may not be the most stable. If you have any comments or questions, let me know.

Hello World

I am going to try and resurrect this site again. This time I will be using WordPress which should make adding updates much easier. There will also no be some dynamic content such as comments, so overall, I think this will be a much better experience. For at least a little while there will be a lot of small changes to the site, so sorry in advance for the inconvenience.
