Yes I'm using 1000x1000 maps, with each map being 50x50. While I'd been
reading C and Python code I'd come to suspect there were implicit
assumptions that the world tile maps would be 50x50. Yes this could be
fixed but I found it easier just to stick to the existing standard.
It's worth noting that the name of the new world is Quadra and I've layed
the tiles out in a directory tree to avoid the issues of having too many
files in a single directory. So the map tile for maps 117,117 on my new
I've written a script which take the tiles generated by 'land' or
'bigland' and sets the tile paths correctly. I have special plans for the
edge maps which are worth their own post some other time.
With map tiling, things can move to adjacent maps even if players don't move
to them. The game doesn't really distinguish between objects, and just as
you wouldn't want an arrow to stop at a map edge, same goes true for
That's great. I think that has some potential to make really interesting
What should eventually happen is that maps with no players on them will get
swapped out. However, what probably also happens is that maps that are still
in memory are touching the other maps, keeping them active, so this never
happens (at least in the case of mice which keep multiplying). One could
have a monster that just wanders and moves to a new map, but it would
eventually get swapped out if nothing else is keeping the map it is on

I could cut the world down to 500x500 maps and add the rest back when the
cost of storage drops but I'm hoping not to have to do that.
newer filesystems (ZFS for example) support compression, eg:
NAME USED RATIO
export/home/crossfire 18.0G 2.09x
FreeBSD? Few will be using ZFS on Linux I think and I'm not trusting my
data to Btrfs just yet :) There seems to be a FUSE option for on-the-fly
compression but there are concenrs about stability. Other than that I
think Linux users have few options for on-the-fly compression but happy to
hear about options I may have missed.
If we applied the map compression in the application it would work on any
OS that the game runs on.
I compressed a few random tiles from my new world and got compression
rations ranging from 6:1 to 10:1.
