packet_to_string now returns a Result as not to crash the app when
showing TextView on a packet that fails to decode for whatever reason.

... changes... wel, lets see... uuhhmmm, i rewrote the entire packet
inspector :)
(also dont mind the snarkyness of that sentence, im tired)
closes#346
## Description
Solidify the design of `valence_anvil` so that most of the boilerplate
in the anvil example is eliminated. `AnvilLevel` is now a component of
`Instance` and automatically loads and unloads chunks as clients move
around. Events are used to communicate when chunks are loaded and
unloaded.
Also changes the system message API and introduces the `SendMessage`
trait.
Checks off a box in #288
### Known Issues
- Still no support for saving or entities.
- The handling of chunk `min_y` is wrong. I plan to fix this in an
upcoming redesign of instances and chunks.
- Uses one OS thread per anvil level. This could be improved with a
dedicated shared thread pool to parallelize the loading process.
However, it seems decently fast as it is.
- Old benchmark is commented out.
- Could use some tests.
## Description
Basic implementation of world border
World border is not enabled by default. It can be enabled by inserting
`WorldBorderBundle` bundle. Currently, this PR only implements world
borders per instance, I'm considering expanding this per client.
However, the same functionality can be achieved by Visibility Layers

## Description
- Revert the "biomes/dimensions as entities" idea since it caused too
many problems without much to show for it.
- Make use of `valence_nbt`'s serde support in `valence_biome` and
`valence_dimension`.
- Reduce boilerplate, reorganize `valence_registry` a bit.
- Tweak default biome registry such that `BiomeId::default` always
corresponds to "minecraft:plains".
- Add `Option` and unit variant support to `valence_nbt`'s serde impl.
## Description
- Reorganize `valence_nbt` and feature flag the different parts. SNBT
and binary serialization are each behind their own flags.
- Add optional serde support to `valence_nbt` behind the `serde` flag.
This is useful for end users working with `valence_nbt` and allows us to
simplify some code in `valence_biome` and `valence_dimension`.
Note that this includes a `Serializer` and `Deserializer` for `Compound`
and _not_ the binary and SNBT formats. In other words, it's not possible
to go directly from an arbitrary data format to binary NBT and vice
versa, but it _is_ possible to go to and from `Compound` and finish the
(de)serialization this way. I consider this an acceptable compromise
because writing fast and correct serialization routines for `Compound`
becomes more difficult when serde is in the way. Besides, the
intermediate `Compound` often needs to be created anyway.
- Fixed unsound uses of `std::mem::transmute` in `valence_nbt` and
elsewhere. Using `transmute` to cast between slice types is unsound
because slices are `#[repr(Rust)]` and the layouts are not guaranteed.
`slice::from_raw_parts` is used as the replacement.
- add Tags extractor
- add tags.json to extracted
- send `SynchronizeTagsS2c` packet on join
- fix encode
## Description
Adds a `TagsRegistry` resource that contains all the information needed
to build and send `SynchronizeTagsS2c` on join.
closes#349
## Description
- Move all packets out of `valence_core` and into the places where
they're actually used. This has a few benefits:
- Avoids compiling code for packets that go unused when feature flags
are disabled.
- Code is distributed more uniformly across crates, improving
compilation times.
- Improves local reasoning when everything relevant to a module is
defined in the same place.
- Easier to share code between the packet consumer and the packet.
- Tweak `Packet` macro syntax.
- Update `syn` to 2.0.
- Reorganize some code in `valence_client` (needs further work).
- Impl `WritePacket` for `Instance`.
- Remove packet enums such as `S2cPlayPacket` and `C2sPlayPacket`.
- Replace `assert_packet_count` and `assert_packet_order` macros with
non-macro methods.
To prevent this PR from getting out of hand, I've disabled the packet
inspector and stresser until they have been rewritten to account for
these changes.
- update aes and cfb8 and make it compile
- update some usages to fix lints
- fix it so that it actually works

## Description
Remove the "test plan" section from the pull request template. My
justification is:
- The steps needed to test a pull request is usually obvious.
- Often the test plan is just "run `cargo test` lol"
- For small changes and tweaks, a "test plan" is overkill and amounts to
frustrating busywork.
- Adds too much additional friction for new contributors.
- Large projects like Bevy are fine without it.
- Often not applicable to pull requests (like this one).

## Description
Added a new reset flag, which resets all old advancements and don't show
a toast for already completed advancements
## Test Plan
Use example "advancements". Now it saves old progress of player
## Description
Did an api for advancements.
Issue: https://github.com/valence-rs/valence/issues/325
Each advancement is an entity, it's children is either criteria, either
advancement.
Root advancement has no parent.
Also did an event AdvancementTabChange (listens if client changes
advancement's tab)
## Test Plan
Use an example "advancements"
## Description
Completely re-written the ci build script for more parallelization and
speed.
## Test Plan
1. make/merge a pr
2. watch ci go wroom
3. ?
4. profit
## Description
This should _temporarily_ fix the heck issue described in #324 until
https://github.com/withoutboats/heck/issues/42 is fixed downstream.
When it is fixed downstream, this commit should get reverted.
Fixes#324
## Description
Adds a benchmark to measure the duration of a whole server tick.
Also added `bevy_ecs` to `valence::prelude`.
## Test Plan
Steps:
1. `cargo bench idle_update`
## Description
- `valence` and `valence_protocol` have been divided into smaller crates
in order to parallelize the build and improve IDE responsiveness. In the
process, code architecture has been made clearer by removing circular
dependencies between modules. `valence` is now just a shell around the
other crates.
- `workspace.packages` and `workspace.dependencies` are now used. This
makes dependency managements and crate configuration much easier.
- `valence_protocol` is no more. Most things from `valence_protocol`
ended up in `valence_core`. We won't advertise `valence_core` as a
general-purpose protocol library since it contains too much
valence-specific stuff. Closes#308.
- Networking code (login, initial TCP connection handling, etc.) has
been extracted into the `valence_network` crate. The API has been
expanded and improved with better defaults. Player counts and initial
connections to the server are now tracked separately. Player counts
function by default without any user configuration.
- Some crates like `valence_anvil`, `valence_network`,
`valence_player_list`, `valence_inventory`, etc. are now optional. They
can be enabled/disabled with feature flags and `DefaultPlugins` just
like bevy.
- Whole-server unit tests have been moved to `valence/src/tests` in
order to avoid [cyclic
dev-dependencies](https://github.com/rust-lang/cargo/issues/4242).
- Tools like `valence_stresser` and `packet_inspector` have been moved
to a new `tools` directory. Renamed `valence_stresser` to `stresser`.
Closes#241.
- Moved all benches to `valence/benches/` to make them easier to run and
organize.
Ignoring transitive dependencies and `valence_core`, here's what the
dependency graph looks like now:
```mermaid
graph TD
network --> client
client --> instance
biome --> registry
dimension --> registry
instance --> biome
instance --> dimension
instance --> entity
player_list --> client
inventory --> client
anvil --> instance
entity --> block
```
### Issues
- Inventory tests inspect many private implementation details of the
inventory module, forcing us to mark things as `pub` and
`#[doc(hidden)]`. It would be ideal if the tests only looked at
observable behavior.
- Consider moving packets in `valence_core` elsewhere. `Particle` wants
to use `BlockState`, but that's defined in `valence_block`, so we can't
use it without causing cycles.
- Unsure what exactly should go in `valence::prelude`.
- This could use some more tests of course, but I'm holding off on that
until I'm confident this is the direction we want to take things.
## TODOs
- [x] Update examples.
- [x] Update benches.
- [x] Update main README.
- [x] Add short READMEs to crates.
- [x] Test new schedule to ensure behavior is the same.
- [x] Update tools.
- [x] Copy lints to all crates.
- [x] Fix docs, clippy, etc.

ECS. Entry components overlap with client components where possible.
- Clients are now automatically added and removed from the player list
unless configured not to.
- Updated player list example.
## Test Plan

## Description
Closes#296
- Redesigned the packet decoder to return packet _frames_ which are just
the packet ID + data in raw form.
- Made packet frame decoding happen in the client's tokio task. This has
a few advantages:
- Packet frame decoding (decompression + decryption + more) can happen
in parallel.
- Because packets are parsed as soon as they arrive, an accurate
timestamp can be included with the packet. This enables us to implement
client ping calculation accurately.
- `PacketEvent`s are now sent in the event loop instead of a giant match
on the serverbound packets. This is good because:
- Packets can now be handled from completely decoupled systems by
reading `PacketEvent` events.
- The entire packet is available in binary form to users, so we don't
need to worry about losing information when transforming packets to
events. I.e. an escape hatch is always available.
- The separate packet handlers can run in parallel thanks to bevy_ecs.
- The inventory packet handler systems have been unified and moved
completely to the inventory module. This also fixed some issues where
certain inventory events could _only_ be handled one tick late.
- Reorganized the client module and moved things into submodules.
- The "default event handler" has been removed in favor of making
clients a superset of `PlayerEntityBundle`. It is no longer necessary to
insert `PlayerEntityBundle` when clients join. This does mean you can't
insert other entity types on the client, but that design doesn't work
for a variety of reasons. We will need an "entity visibility" system
later anyway.
## Test Plan
Steps:
1. Run examples and tests.
## Description
Stops packets for the client's own entity being sent back to the client.
This prevents the "ghost player" from appearing at spawn.
## Test Plan
Steps:
1. `cargo r --example bench_players`
2. Press F3
3. Look at where the player spawned. Notice that there is no ghost
player entity.
4. Look at received packets `rx`. Moving around in a chunk, you will not
receive packets for the player's own entity. `rx` should be close to
zero.
## Description
Updated the Particle enum for 1.19.4
## Test Plan
Steps:
1. Run the particles.rs example
---------
Co-authored-by: Ryan <ryanj00a@gmail.com>
## Description
Closes#291
- Update extractors to support Minecraft 1.19.4
- Update code generators.
- Changed generated entity component names to avoid name collisions.
- Update `glam` version.
- Added `Encode` and `Decode` for `glam` types in `valence_protocol`.
- Fixed inconsistent packet names and assign packet IDs automatically.
- Remove `ident` and rename `ident_str` to `ident`.
- Rework registry codec configuration. Biomes and dimensions exist as
entities.`BiomeRegistry` and `DimensionTypeRegistry` resources have been
added. The vanilla registry codec is loaded at startup.
### Issues
- Creating new instances has become more tedious than it should be. This
will be addressed later.
## Test Plan
Steps:
1. Boot up a vanilla server with online mode disabled.
2. Run the `packet_inspector`.
3. Connect to the vanilla server through the packet inspector to ensure
all packets are updated correctly.
4. Close the vanilla server and try some valence examples.
## Description
Makes `Ident` consistent with vanilla by prepending the default
namespace if none is provided in the constructor.
Previously, the constructor did not normalize `foo` to `minecraft:foo`.
This could lead to subtle bugs when the ident is eventually unwrapped
with `Ident::as_str`. (comparing `foo` with `minecraft:foo` while inside
the `Ident` was still handled correctly).
## Test Plan
Steps:
1. `cargo test`
## Description
The client actually doesn't acknowledge the state id update when you
modify the cursor item, so don't increment it so we stay in sync.
fixes#304
## Test Plan
Explain the steps necessary to test your changes. If you used a
playground, include the code in the details below.
Steps:
1. Run the playground from #304 (not included here for brevity)
2. open inventory (not chest)
3. pick up one of the stacks
4. see that you don't get resynced, and the apples stay in your cursor
## Description
This adds some validation for incoming inventory packets that makes it
so that you can't just spawn items by sending malicious packets. It adds
type 1 and type 2 validations as outlined in #292.
This also adds some new helpers, `InventoryWindow` and
`InventoryWindowMut`.

# Description
- Removed the advice about making examples as small as possible in
CONTRIBUTING.md
- Remove a couple of low-value examples. I would like to remove more,
but their functionality would have to be covered by better examples
first.
My reasons are:
- Examples are tedious to update and maintain. Boilerplate is
inevitable.
- The "Boilerplate to code" ratio is higher when examples are smaller.
- Examples are likely the first thing that new users will try out, so we
ought to make a good first impression by showing something substantial.
- Complicated examples are better for showing how to use Valence in
practice and serve as a useful reference.
- Lots of small examples can distract from the more impressive ones.
Tiny examples don't add much value.
## Description
Adds the `dump_schedule` crate which is a simple tool that writes
valence's schedule graph to a file named ~~`graph.gv`~~ `graph.svg`.
## Test Plan
Steps:
1. `cargo r -p dump_schedule`
2. Paste the contents of `graph.gv` to https://edotor.net/
3. Look at the pretty graph.
… filters case-insensitive
Closes#297
## Description
Up and down arrow to select previous/next packet now ignore filtered
packets.
## Test Plan
1. Query the server using refresh on the server browser
2. Uncheck QueryResponseS2c in the packet-selector list
3. Click HandshakeC2s
4. Press down arrow until last packet is selected
5. It shouldn't go "blank" anymore when going from QueryRequestC2s to
QueryPingC2s
As an additive request, I've removed the regex check from the main GUI
filter box, such that this is now case-insensitive when filtering
specific packets.
CLI still uses regex to be able to filter on multiple packets
(unchanged)
## Description
Closes#269Closes#199
- Removes `McEntity` and replaces it with bundles of components, one for
each entity type.
- Tracked data types are now separate components rather than stuffing
everything into a `TrackedData` enum.
- Tracked data is now cached in binary form within each entity,
eliminating some work when entities enter the view of clients.
- Complete redesign of entity code generator.
- More docs for some components.
- Field bits are moved out of the entity extractor and into the valence
entity module.
- Moved hitbox code to separate module.
- Refactor instance update systems to improve parallelism.
### TODOs
- [x] Update examples.
- [x] Update `default_event_handler`.
