Use the "wielditem" visual type for non-node items, with a fixed 45
degree yaw. This matches the recent change of dropped-item entities from
"sprite" visual to "wielditem".
Also phase out "old new" API, leaving only the "tube_connects={}" method,
as nothing in technic or pipeworks uses it.
Fix a few more places where minetest.facedir_to_dir() was duplicated, since
that code is part of Minetest 0.4.8.
1) Refactor autoplace,
There was a lot of redundant code and like a dozen unneccessary string
scans for every node next to every tube placed! I put it all into
indexed tables and loops instead of bizarre and unexplainable variable
names and copy and pasted code. There was also no support for notifying
a chest when an item has been taken from it by a filter, so I added
something for that.
I also thought it prudent to fall back on the
allow_metadata_inventory_take function should a special can_remove not
exist. In fact if can_insert doesn't exist, it calls
allow_metadata_inventory_put instead.
I also added a thing for allowing pipes to attach to nodes of other
modules, without having to hard code type all those node names into
autoplace.lua. Basically node.tube.collects(i,param2) and i is the
direction from the pipe and param2 is the param2 of what it's pointing
at.
I also abstracted the inscrutable correlation between i and
param2 by trial and error (and the paramwand mod) into understandable
functions. There was no pipeworks namespace so I created it, and put
these functions into pipeworks.collects (as distinguished from a
node.tube.collects function, which uses those functions)
And now it's too late to cart my old clothes to the thrift store,
dangit.
2) My "node.tube.collects" idea might be redundant with the
node.tube.connect_sides thing, though possibly more versatile so I'll
leave it in.
3) I was using node.tube.connects and fancy functions for checking if it's
the sides or top or whatnot, and this connect_side thing came in. This
should make both my way and the way using connect_side work.
Also removed some debugging cruft
autocrafter, nodebreaker, deployer, and made sure each item will only
initiate a connection to those sides which can accept such. Fixed
various autorouting bugs as I ran across them. Autorouting for various
devices is now:
filters: left and right sides only
nodebreaker, deployer: back only
autocrafter: all six sides
chests: top, bottom, left, right, back (not front)
furnace: bottom, left, right, back (not the top or front)
Items can now flow from one chest (or Nore's filter object) to another via the
pneumatic tubes! Thanks to Nore and RealBadAngel for the code.
Note that this mod has to redefine the default chests and furnaces (see
compat.lua) in order to add some new group definitions so that tubes can
appear to connect to these objects.
