Blog Reaction - Sourceforge.net

Blog reaction:

I'd like you to pick another project using Java (search for Java), download it, and check out the source code. Put your reactions to the site (http://sourceforge.net/) and the code you downloaded on your blog.

I went to Sourceforge.net and started looking in the games section as I like video games. I looked at two in particular. One was Doomsday Engine and the other was Mega Mario. Doomsday Engine is an add-on to the original Doom games that updates the graphics. As interesting as this was, it did not include any source code. I then checked out Mega Mario as that based on a very popular game series, the Super Mario Bros series. Part of the code looks like this:

And this is only for the player. There is coding for so many different aspects of the game. While I myself am not a programmer by nature, I do appreciate the work that goes into these games. These are not big time software developers that get paid to do this, these are everyday people who enjoy this sort of thing and do it for the love of their hobby.
