Nice space invaders clone. You even added the barriers - I can't recall playing a clone that implemented those. In fact when I made this game years ago I didn't even implement them. The only thing that seemed a little strange was the invisible wall that bounds the left and right sides of the playfield. I feel like the ship should be able to move closer to the edge, or there should be some sort of visual clue indicating where those boundaries are.

Thanks, Derek. I had fun writing it so I appreciate the kudos. The barriers are one of the things I'm most proud of. Getting the destruction algorithm just right took me longer than almost anything else.

As for the ship boundary, believe it or not, that was part of the original game as well. It didn't let the player's ship move as far left or right as the aliens do. But I like your suggestion for a visual indication of the boundary. I'll consider that.

Taylesworth,

Nice looking screenshots. I have an original Space Invaders arcade game in my gararge and your version looks much better than the original. I'll download it tommorow (long day today) to give it a spin.

One possibility is darkening or removing the inaccessible parts of the bottom border line. You'd have to shift the spare ships over a little bit as well, but that's a minor detail.

Excellent source code and libraries!!
Very well done, guy!

Thanks, nicomn. I've already updated my library to provide features I need for my next project (including loading texture and sprite data from an XML file instead of having those constants sprinkled throughout the code). I may get around to releasing it on its own for people who want a 2D graphics library.
