Instead of re-gening the chunk, it now removes it and leaves it alone.
The reason is that, now that the cache dir is separated from the chunk
data files, there's no way for that code to know where it came from. For
now, it's easier to just omit that one chunk, it'll be re-generated on
the next run anyways.
The spawn point is automatically added to the gmap as a marker.
Adding other markers (signs, mob spawners, etc) should be fairly
easy. Note: the math that converts from in-game block coordinates
to pixel coordinates is iffy. it requires a careful codereview
Added an option to enter your own zoom level. Use -z to set the map at a
particular zoom level. Zoom levels define the width and height in tiles
of the highest zoom level, each new zoom level is twice as wide and
tall. (z=6 -> 2^6 tiles wide and tall)
Implemented tile re-arrangement on map expansion. Now most tiles will
get re-used if your map needs another zoom level! No longer does it need
to re-generate everything.
No longer creates empty directories for tiles, only creates directories
if needed.
Fixed some minor off-by-one logic (and the code that canceled it out to
make it work)
When the world expands and the Overviewer is forced to create a new zoom
level, use to be all tiles needed to be regenerated. Now that the world
center is always anchored, I can do some simple renaming of folders so
now when a world expands, tiles are re-used and it's very quick!
This more effectively utilizes as many cores as you tell it. It should
now spawn a new process whenever an old branch of the recursive tree
finishes, to always use as many processes as you specify.
The initial recursive call for tile generation will spawn up to 3 extra
processes to work on each quadrant. It's not perfect yet since some
quadrants may have more or less work to do, and only 4 total workers are
supported.
Also, it waits for all chunks are finished before it dives into the
tiles, to prevent it from using more resources than requested.
Re-factored the way the textures and blocks are being built. It should
be easier to understand and add new exceptions (sorta). Also fixed the
water and lava with other texture packs by putting a static water.png
and lava.png in with the code.
This causes the parent process to re-raise the exception when it
eventually tries to get() the result from the child, instead of hanging
forever on a ctrl-C. It doesn't happen immediately, which is not ideal,
but at least things will eventually exit on ctrl-C now.
