1. Fixed mistakes in PocketBuilder that would cause dungeons to be
initialized as non-dungeon pockets. This restored Monolith spawning
around dungeons.
2. Fixed a bug in DungeonSchematic - returning links through entry doors
should work now.
3. Made minor changes to DungeonSchematic for clarity
Fixed the issue with integrated servers causing circular updates between
the combined server and client. We now check on the client side whether
the connection we're receiving data from is a memory connection (which
is presumably only used by integrated servers). If so, the client
ignores any incoming packets. We don't just disable update events
altogether because LAN games will require updating remote clients.
Also fixed a bug in PocketManager.unload() - we weren't setting isLoaded
to false after unloading everything and unregisterPockets() had to be
called before setting dimensionData to null.
Fixed more bugs. Now it's possible to generate a world without crashing.
Unfortunately, it's clear that there is a packet-sending loop going on.
I'll have to add a check to prevent integrated servers from spamming
themselves.
Finished implementing all the packet handling code. It could be improved
in the future to compress the initial packet sent to clients. With this,
the code is complete enough to run! Commands have not been fixed yet but
that will come in the future.
Threw out the complicated architecture that I'd made for synchronizing
server and client data perfectly. Instead, we now send just enough data
to the client and the resulting code is simpler. Some of the client-side
code is also done so all packet handling should be finished soon.
Continued building a system for transferring the complete internal
states of our dimensions from the server to the client. However, Steven
suggested that clients only need minimal data to operate properly, as
opposed to the server. My motivation for this more complicated system
was the concern that minimal information wouldn't be enough. I'm going
to commit my progress, then tear it down and write a much simpler
version.
Moved the DimLink code out of NewDimData in order to reduce clutter
inside that class and made it a separate class, except for functions
that should only be available for NewDimData. Deleted IDimLink and
changed all references to it to use DimLink instead. DimLink is now an
abstract class, which achieves the same encapsulation and protection we
had before by having DimLink implement IDimLink from within NewDimData.
NewDimData has a new class inside, InnerDimLink, which provides it
access to special functions that would be dangerous to expose. This is
the same mechanism used to protect NewDimData's dangerous functions.
These changes are in preparation for adding more code for packet
handling.
Not checking if a chunk existed before we placed a rift block could
cause the MC server to generate chunks in unloaded terrain. Bad things
commence. Possible world leak canidate.
Started rewriting our packet handling code. Deleted PacketHandler in
favor of using sided (Server-, Client-) packet handlers to make it
easier to follow what's going on in our code. Added some event-based
handling of updates which greatly simplified signaling that data needs
to be sent, but it's not completely done yet.
Modified how links are created so that the caller must specify a link
type when the link is created, rather than setting it later. This was
done to avoid having to send two link data packets following the way
links would be handled logically. Turns out this was good idea overall
for ensuring link integrity, because there was one case where I forgot
to set the link type after creating the link.
Fixed the code in DDTeleporter and made minor changes to other classes
that depended on those fixes. Ensured that PocketManager's load, save,
and unload methods are called appropriately and rewrote some of their
code. Made various changes in other classes (e.g. EventHookContainer,
PlayerRespawnTracker) to pass them references to DDProperties through
their constructors instead of having them rely on
DDProperties.instance() - this is a better programming practice in the
long run.
Renamed initialization methods in mod_pocketDim to make it clear that
they're called on events. Commented out command registration in
mod_pocketDim so that we can test DD as soon as PacketHandler is fixed,
without worrying about fixing the command classes.
Fixed the code in ItemLinkSignature and ItemStabilizedRiftSignature.
Removed obsolete code from PocketManager - we don't need to worry about
storing link keys anymore. All the data is stored in NBT, which means no
more generating unique keys or worrying about saving and loading them.
Moved tile entity classes to a separate package. Renamed some block
classes to match their in-game names (e.g. ChaosDoor -> UnstableDoor).
Moved TransientDoor to the blocks package. Cleaned up a little bit of
the code and automatically updated references to the classes that were
modified.
More cleaning up errors and code. There were a lot of things that needed
simplifying. Rather than fix the 3 or 5 copies of the same function
throughout the code, I made an effort to use the same function and
delete its copies.
Created the BaseItemDoor class to hold all the basic door item methods
that don't vary between types. That helped cut down on fixing things.
Also renamed the door item classes to match their in-game names.
There is still a ton of duplicate code out there.
Continued fixing things across various classes to make them work with
our new core classes. I've also cleaned up indentation and random code
snippets along the way.
1. Changed DungeonSchematic to use an external instance of Random rather
than initializing its own.
2. Created the Pair class, a strongly-typed tuple that was needed in
PocketBuilder.
3. Added a missing calculation in NewDimData for setting the packDepth
field during dungeon initialization.
4. Finished code missing in PocketBuilder. Changes listed above were
needed for this.
Replaced several core classes from DD with new classes to enforce
integrity checks. Rewriting everything that depended on those classes is
a massive undertaking but it should simplify our code and prevent the
many bugs we've seen lately. The rewrite isn't done yet, just committing
my progress so far.
DDLoot: Implemented a custom version of MC's generateChestContents() for
our own chests. It avoids two notable bugs that affect MC's version.
FillContainersOperation: Changed code to use
DDLoot.generateChestContents()
SchematicLoader: Fixed a bug in the way we calculated a seed for
selecting our dungeons that would cause certain seeds to dominate all
the others. Under certain circumstances, the function would only return
-1. That would make our dungeon selection severely biased. That was
resolved and the code was specifically tuned for seeding Java's Random
even for doors with nearly identical positions. The result was an
apparent major improvement in the randomness of dungeons.
ruins\rules.txt: Changed the dungeon generation rules to precisely match
the complicated scheme we had before. We're still using simple rules to
choose dungeons - I used a program to derive the effective distribution
of dungeon types that the old code would produce and converted it into
the current rule system.
Created NewLinkData and replaced references to the original LinkData.
Moved it to the mod_pocketDim.core package. Added Point4D, an immutable
point type for 3D integer coordinates with an added dimension ID.
Added code so that the mod loads dungeon packs stored in the custom
dungeons folder. Changed the code for loading bundled dungeons so that
they're loaded as dungeon packs. This means dungeon packs are now fully
integrated into the mod. The changes were tested and seem to be working
perfectly.
1. Integrated support for dungeon pack config options into the code
(i.e. we actually DO what the settings specify)
2. Added random transitions from one dungeon type to another. Dungeons
might also begin with a non-default pack.
3. Fixed a config reading bug that caused settings to be ignored and
some invalid settings wouldn't trigger exceptions. Also fixed other
dungeon pack bugs.
Added code for parsing dungeon pack config files. The settings for our
built-in dungeons are now read from a file instead of being hardcoded.
One or two settings aren't being accessed yet and we still don't search
for other dungeon packs in the custom dungeon folder. That'll come in
another commit.
This is used for the code that determines where to come out of Limbo in. It tries to search from the top down to find a solid block to stand on. Isn't complete, though. This code does need some considerations put in, though... I'm concerned about Natura's clouds, for instance.
Made some changes to EventHookContainer.onWorldLoad() to remove
redundant code that encouraged bugs. Unfortunately, a lot of
link-related code needs to be rewritten to get rid of bugs, so that'll
come after dungeon packs are completed.
Changed how Random is initialized in SchematicLoader to prevent issues
with dim doors in the same chunks leading to the same dungeon. The
selection seems much more varied now. Also changed the hardcoded config
for the default dungeon chains to the one we'll be using later (from a
file). For testing purposes.
Decreased the default chance of a gateway generating. This won't affect
users unless they clear their config files. The decision is based on
user feedback and recent experiments on how common gateways could be.
Modified RiftGenerator to correct for the rarity of Rift Gateways in the
Nether. Our config settings allow us to set the probability that we will
attempt to generate a gateway in a given chunk. However, that doesn't
guarantee that a gateway will generate.
I collected a lot of data and determined that generation succeeds in the
Nether only about 15% of the time. That's compared to 30% in the
Overworld when counting oceans (which always fail) and about 75%
(sometimes higher) when traveling mainly on land.
RiftGenerator now corrects for this by multiplying the chance of
attempting to generate gateways in the Nether by 4. Gateways in the
Nether are still relatively rare and hard to find, but you'll
occasionally come across them now. Also reorganized the code a little
for clarify.
Exit doors are safer now, but only dungeon exit doors will stop you from
falling into liquids.
Doors you place in pockets you make will happily drop you into lava, but
not spawn you inside of it.
Dungeon gateway orientation fix
Removed excess .schematics and fixed one of them.
Completed a basic version of configurable dungeon chains. Almost all of
the final funcionality is present. However, the configuration is
hardcoded at the moment, not read from a file. This was done for testing
purposes. I'll add reading from config files soon.
Dungeon packs are partially implemented. Built-in and custom dungeons
are currently thrown into the default pack, Ruins. The next step is to
generalize the dungeon registration code in DungeonHelper so that we can
detect dungeon packs, read their config files, and register dungeons
with their corresponding pack. dd-export will need to support packs as
well. dd-rift will have issues dealing with duplicate dungeon names
across packs, but this isn't a major concern and can be dealt with in
the long term.
Completed enough of the implementation and integration to compile DD.
Some portions of the code are only for testing and will be removed
later. The configuration for default dungeons is hardcoded - we can
parse config files once we're certain that dungeon chains work. At the
moment, dungeons generate but it doesn't seem like the rules we set are
being followed properly.
Renamed OptimizedRule to DungeonChainRule, and renamed the old
DungeonChainRule to DungeonChainRuleDefinition, to match the role of
each class better. Added some hax to DungeonGenerator to get packs
integrated - the implementation will be much cleaner once the new save
format is done.
Started implementing our support for dungeon packs. The code is not
usable yet and the mod is not functional at this stage. A few additional
changes should make it testable. A significant obstacle to implementing
dungeon packs easily is that DungeonGenerator doesn't have some
necessary information and shouldn't be modified. Even if it is modified,
old serialized instances wouldn't have the new fields initialized. I'm
having to create workarounds until we implement the new save format.
DungeonPack handles all of the logic of selecting a dungeon and
verifying whether its type is valid. It relies on DungeonChainRule and
OptimizedRule to check which dungeons should be generated next given a
list of the dungeons in a chain. DungeonType maps types in packs to ID
numbers and provides a reference to the pack that owns the type.
DungeonPackConfig will carry config information to be passed to the
DungeonPack constructor.
Removed glass from the list of blocks immune to rifts. That was just a
temporary change so that I could check how rifts were destroying blocks
in a controlled manner.
Made it so rifts destroy blocks in layers rather than destroying random
surrounding blocks, even through indestructible blocks. This resolves
issue #24.
Made rifts check block hardness while replacing blocks so that we can
avoid destroying strong or indestructible blocks from other mods.
Updated references throughout the code to use a function in BlockRift
for this purpose.
Added support for rotating the metadata of powered tracks and detector
tracks. Also made a minor change to DungeonSchematic to protect its
internal state.
Changed BlockRotator so that missing stair types are recognized for
applying rotations. The general code for all stairs was there but the
block IDs for wooden and brick stairs weren't recognized. Also removed a
duplicate reference to nether brick stairs.
Simplified metadata rotation code by only having a single function that
rotates metadata by 90 degrees clockwise and applying it repeatedly for
180 and 270 degree rotations. Removed flipDoorMetadata() from dimHelper
and replaced all references to it with references to BlockRotator. This
makes all our rotations reference a single function. Replaced hardcoded
rotation in DungeonSchematic.
Added support for wood (tree trunk) and quartz pillar metadata
rotations.
Converted the doors in our schematics into doors from DD. Also converted
mangled block IDs into Fabric of Reality and wiped all tile entities
from Steven's schematics to remove prefilled chests that had been
included somehow. Changed DungeonSchematic to expect mod doors now. This
means we can include Vanilla doors in our designs and they will not be
converted anymore.
This process was done by automatically re-exporting all of our dungeons
multiple times, so it serves as a good test that importing and exporting
are working properly. We confirmed by thorough testing that our
schematics load properly into WorldEdit. MCedit, unfortunately, does not
handle them right. We believe this is a bug in MCedit, NOT with us.
Fixed rifts not moving correctly when moving dungeons to stay inside
world bounds
Regular pockets stay in world bounds.
RiftRegenerator no longer NPEs
Fixes#48, #63
Changed SchematicLoader to use new dimHelper functions to move links
around. This should have allowed us to shift dungeons safely.
Unfortunately, Minecraft still crashes, so the link functions aren't
working as advertised. Please figure out what's going on. >_< The code
is done, it's just link issues that prevent it from working.
Completed changes so that our code uses registerDungeon() (formerly
registerCustomDungeons() ) to register all dungeons, both bundled with
the mod and custom ones. Made some changes to the code to hide
implementation details from other classes. Also, I had some problems
with old dungeons being mixed into the renamed ones. I had to remove
fallingTNThall from the schematics folder and deleted the WIP folder
because I think we have completed versions of those schematics already.
Some of our dungeons have pre-filled chests and the contents are more
generous than our current loot system (e.g. ruinsO has a prefilled
chest). I'll have to wipe all the chests later.
Forgot to fix a reference to DungeonHelper in CommandCreateDungeonRift
during the last commit. Made some further improvements to DungeonHelper
to avoid exposing internal variables.
Removed hardcoded references to all our internal dungeons. The code will
be replaced by reading from a list in the next commit. Renamed
customDungeons to untaggedDungeons and removed registration of tagged
dungeons into that list. Now all tagged dungeons (custom and internal)
are listed in registeredDungeons. Fixed the comparator used to sort
dungeon names so that it sorts them case insensitively.
We now check whether structure generation is allowed. This can be
configured on servers and when creating single-player worlds. If set to
false, Rift Gateways will not generate. Rift clusters still generate.
That was an intentional feature - we could make the setting disable
those as well if we want.
DDProperties will now throw an exception that should crash Minecraft if
the user tries to use invalid block IDs for worldgen blocks. Should save
everyone some suffering.
Added code to SchematicLoader to adjust the Y coordinate of the
destination link into a dungeon before the dungeon is created.
IMPORTANT: The code is commented out at the moment because it causes a
link-related NullPointerException. A link needs to be updated through
DimHelper but the code is hard to follow so I've decided to just not
touch it - Steven will have to do it.
The function adjustDestinationY() checks if the given entrance location
would place any portion of the dungeon outside the vertical bounds of
the world. If so, it corrects the location while moving it as little as
possible from its original place.
Also added some checks to make sure that any schematic we load has an
entrance door. Otherwise, load defaultBreak instead. And I cut down on
the absurd number of compiler warnings in dimHelper. <_< Stop accessing
static fields as instance fields!
Added validation to SchematicLoader that prevents dungeons beyond
certain maximum dimensions from being loaded. Our current limits are the
same as the largest dungeon we could export. Rewrote
generateDungeonPocket() to handle that possible failure better.
Made a minor change to DungeonSchematic so that it replaces foreign mod
blocks with the standardized FoR ID on export. Previously it used the
Forge-assigned ID, but since that happens after ID standardization, it
could cause us to export non-standard IDs.
Fixed the bugs that caused doors not to appear right in dungeons. First
there was a bug with filters that caused them not to replace blocks
properly. I made some changes to SchematicFilter and its derived classes
so that the implementations are a little more intuitive. That should
prevent those bugs in any future derived classes. Then doors wouldn't
rotate properly. DD was never designed to rotate dimensional doors. I
added code to BlockRotator for that and shifted some code from
DungeonHelper to BlockRotator. More coherence, less coupling!
