Rewrote the code that changes the position of a tile entity to be
expressed in the schematic coordinate system. The new code should be
equivalent but easier to understand.
Added support for exporting tile entities as part of custom dungeons.
I've produced a schematic as a test that shows items are exported
properly and they're recognized in MCedit. I still need to add support
for loading tile entities in imported schematics.
Changed DungeonHelper.exportDungeon() to use Minecraft's NBT tag classes
instead of using JNBT. The implementation is actually slightly simpler
than our original JNBT version. I also fixed a bug in the way the
extremes of the bounding box search were calculated that caused yEnd to
have an incorrect value. Exporting works properly now. Confirmed with
tests.
Fixed the selection of boundaries for custom dungeons. The code had a
bug that would clip off a portion of dungeons during exporting. Also,
permafabric is not used to mark the edges of the dungeon anymore. That
means dungeons can contain permafabric now without getting cut off, and
the permafabric shells will be included as part of the export.
Changed SchematicLoader so that schematics that have entrances that are
not facing North will still be rotated properly. This involves a
workaround for transformMetadata() since it assumes schematics are
always saved "facing" North.
I've tested this and it's working perfectly, with one exception. If you
create a rift with dd-rift to a dungeon that wasn't saved pointing
North, the rifts sometimes appear beside the player, instead of in the
block where the player's head is. Sometimes you'll appear in the dungeon
facing the right way. Other times, you'll appear inside a wall adjacent
to the entrance or near the entrance facing the wrong way. I have not
managed to narrow down why this happens.
Rotations in SchematicLoader are understandable now. I changed all the
code to use transformPoint() and made sure that the rotations in there
are correct. Testing shows that rooms are being generated correctly. I
also edited portions of the code for clarity and removed some debug
prints. The loading process now allows permafabric to generate - it was
previously converted into regular fabric of reality. For the moment,
the code is stuck to assume that the entry direction is North. I'll
remove that constraint in the next commit.
It turns out my earlier commits didn't completely fix things because
certain implementation details were missing. I had assumed they were
done. Also, some of the information I had regarding the default
schematic orientation was wrong. This commit remedies most of those
problems with a robust rotation implementation. However, I haven't added
the code for linking Warp Doors yet, and there is a bug with tile
entities getting reversed in East/West oriented rooms. Not sure why
that's happening.
It turns out that rotation hadn't been implemented in the code I moved
during my last commit. I've changed things slightly to implement
rotation. I also renamed some coordinate variables to prevent confusion.
