I was going to make a jumping style where you jump up and avoid objects like fire, water, and possibly sand. I might develop farther on this design eventually for now that is it. The game will not be the same every time and will have a randomness to the events. The main part i want to emphasize in this game is the physics.
Why can't I have cellular automata use the same gravity?

Yes if I can get it all working correctly I will implement all of those.

I still don't quite get how to do cellular automata efficiently yet so I haven't put it in. I'm slowly adding in game parts and physics. I need collision detection and an efficient way of doing cellular automata. I'll have gravity set up soon. It might be a slightly different way from what you had on the physics lessons.

Here is my code so far All I have it do is move the sprite around with keyboard inputs. I know it is a little slow right now but that makes it easier for me. Next on my to do list is add gravity. I would appreciate any ideas for optimization or improvements.

fullname = os.path.join('data', name)
try:
image = pygame.image.load(fullname)
#If an error exit
except pygame.error, message:

raise SystemExit, message
image = image.convert()
if colorkey is not None:
if colorkey is -1:
colorkey = image.get_at((0,0))
image.set_colorkey(colorkey, RLEACCEL)
return image, image.get_rect()

EDIT: @alberthrocks that is why i intend to at least at 1 point in the game have nearly the whole screen consumed by a mixture of fire and water and That would considerably slow down the game to have to loop through all of them.

OK that is not one I know sorry that I can not be of help.

I am intermediate At python i mainly have used it for pretty simple games. This is my first attempt at a more difficult game. I almost have the basics of the game working right now I need a sprite though and I'm trying to decide what to use.
and it wasn't that I didn't know how to do it it was that i wanted to try and find an optimized way of doing it without looping through every single pixel.

what are you guys programming in and what exactly are you programming? I might be able to help

Could i have an example of some python code for that please. I'm trying to figure out a way to optimize this it would be slow i think if i have to go through most pixels in a nearly if not full screen game.
The only reason i might not do full screen is because i want this to be a very fast game that won't glitch up. i think it would be easier if i had a slightly smaller screen size.

My only calculator is a Nspire so i can't do much on calc testing.
I have not done much with my code yet right now I only have a background. As soon as I start doing much with it I will post my code.

I wanted to know how to do the cellular automata. I also need to be able to do good collision detection and gravity.
First off - have you made the concept on your calculator, and does it work?
Second, are you well versed with Python and Pygame?
Third, can we see some sample code? 
I don't get the first one This is a comp program I'm well versed with python and have done all right with pygame I'm still making up the code, but if you want to see some code I'll post it later. @Builderboy I want to know how to optimize that code and some of the concept

I'm using pygame for graphics. I don't really know any of the other ones
EDIT: if it matters I'm using python 2.6.2

I am currently making a physics game using some of the techniques in this thread http://ourl.ca/4279 I am writing it in python because it is the only language I know well enough to do something like this in. I have a few questions about some things so any help would be appreciated. right now I just finished my skeleton code and am starting on the game engine. I am currently using pygame for graphics, I also have python 2.6.2 My first Question is how could I code Cellular Automata in python for a large/full screen?

15 MB for 1:38 of video on a calc isn't that bad

This is amazing. How large are these files?
