Textures are in

Posted on July 20, 2010 by Alex

Well, here it is, the game, complete with textures.  I’ve even whipped up a set for mouse cursor, ship, and default enemy. A few things to note: The textures themselves are in targa (.tga) format.  I chose that format because … Continue reading →

Projectiles with angles

Posted on July 17, 2010 by Alex

A fairly unimpressive addition today too, but I did one of the three things I said I’d do today.  I made projectiles into arrows that point in the right direction.  I built in the angle data when I was building … Continue reading →

I’ve been going back and forth on whether the objects in this game need to be three dimensional, two dimensional but with polygons defined in OGL to handle transparency and shape, or two dimensional squares with their transparency and shapes … Continue reading →

New and improved

Posted on June 14, 2010 by Alex

Well, the game is improving.  Closing in on “Atari” level gameplay. Major accomplishments of the day: Creating a solid coordinate system, then translating that into pixel coordinates, so things won’t be different on different resolutions. This includes a border that … Continue reading →

A new beginning

Posted on June 12, 2010 by Alex

I’ve unfortunately had to burn the previous effort to the ground.  Ends up SDLs native sort of graphics mode is simply not compatible with openGL, it’s more there to provide a weird sort of backup in case openGL can’t run. … Continue reading →
