The latest version of the Frantic Demo is available for download. Three
missions (9 levels) in the demo to date. I'm going to take a step back
now and decide whether or not it's worth pursuing as a shareware game.
Your feedback will help greatly influence that decision. Thanks to all
who have g

That's not mean, it's honest. Three reviews, three problems with
memory requirements. That's great feedback.

Yes, I'm doing that but I am going to refactor that to load/unload only

Yes, this is definitely a memory vs. CPU tradeoff, and I chose CPU. Of
course, I naively load everything at startup time, which I believe is
the real cause of the memory/loading problems, but I will fix that soon.
BTW, I could use the method you describe below for the starship (and

Sure, but in real time that kills CPU. I'm doing it with pre-rendered
sprites (using a particle renderer in Blender).
Memory vs. CPU.
I did a simple real-time OpenGL astronomy simulation/game for an
observatory a couple years back. Their archaic machines locked up on
some pretty simple animatio
That is how it works. No image is loaded more than once. My resource

So, here is a high-level description of how I am managing sprites in my
Frantic game. Does this sound like SOP or am I way off in the weeds?
Each game object (starship, ufo, enemy, powerup, etc.) has a factory or
manager class that is instantiated once in the game_scene object. It
loads and
I'm using Pygame 1.7.1 on Windows XP. set_icon sets the icon when the
window is collapsed, set_caption sets the caption, and get_caption shows
the correct file name of the icontitle. Anyone else having problems
with this?
__screen__ = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))

I found some image filmstrips I was not unloading after they're cut up
into image arrays, and it freed up a decent amount of memory, but my
game is still a hog. I totalled the amount of disk space for all images
used by the starship (different weapons, explosions, thruster, etc.),
and it's 600Kb.

Down to 5Mb of memory! I refactored what Brian suggested with the
images, as well as some other messy code. More testing to do, but I'll
post the new version later tonight or tomorrow.
Thanks, Brian!

processes going - mine still hogging. Back to the drawing board.

Got that down to 43 - 52 Mb now. Amazing how much I was wasting...
