aligning public apis of Time,Timer and Stopwatch (#15962)
Fixes #15834 ## Migration Guide The APIs of `Time`, `Timer` and `Stopwatch` have been cleaned up for consistency with each other and the standard library's `Duration` type. The following methods have been renamed: - `Stowatch::paused` -> `Stopwatch::is_paused` - `Time::elapsed_seconds` -> `Time::elasped_secs` (including `_f64` and `_wrapped` variants) |

Migrate from Query::single and friends to Single (#15872)
# Objective - closes #15866 ## Solution - Simply migrate where possible. ## Testing - Expect that CI will do most of the work. Examples is another way of testing this, as most of the work is in that area. --- ## Notes For now, this PR doesn't migrate `QueryState::single` and friends as for now, this look like another issue. So for example, QueryBuilders that used single or `World::query` that used single wasn't migrated. If there is a easy way to migrate those, please let me know. Most of the uses of `Query::single` were removed, the only other uses that I found was related to tests of said methods, so will probably be removed when we remove `Query::single`. |

Watching versions of bevy/get and bevy/list with HTTP SSE (#15608)
## Objective Add a way to stream BRP requests when the data changes. ## Solution #### BRP Side (reusable for other transports) Add a new method handler type that returns a optional value. This handler is run in update and if a value is returned it will be sent on the message channel. Custom watching handlers can be added with `RemotePlugin::with_watching_method`. #### HTTP Side If a request comes in with `+watch` in the method, it will respond with `text/event-stream` rather than a single response. ## Testing I tested with the podman HTTP client. This client has good support for SSE's if you want to test it too. ## Parts I want some opinions on - For separating watching methods I chose to add a `+watch` suffix to the end kind of like `content-type` headers. A get would be `bevy/get+watch`. - Should watching methods send an initial response with everything or only respond when a change happens? Currently the later is what happens. ## Future work - The `bevy/query` method would also benefit from this but that condition will be quite complex so I will leave that to later. --------- Co-authored-by: Zachary Harrold <zac@harrold.com.au> |

Migrate cameras to required components (#15641)
# Objective Yet another PR for migrating stuff to required components. This time, cameras! ## Solution As per the [selected proposal](https://hackmd.io/tsYID4CGRiWxzsgawzxG_g#Combined-Proposal-1-Selected), deprecate `Camera2dBundle` and `Camera3dBundle` in favor of `Camera2d` and `Camera3d`. Adding a `Camera` without `Camera2d` or `Camera3d` now logs a warning, as suggested by Cart [on Discord](https://discord.com/channels/691052431525675048/1264881140007702558/1291506402832945273). I would personally like cameras to work a bit differently and be split into a few more components, to avoid some footguns and confusing semantics, but that is more controversial, and shouldn't block this core migration. ## Testing I ran a few 2D and 3D examples, and tried cameras with and without render graphs. --- ## Migration Guide `Camera2dBundle` and `Camera3dBundle` have been deprecated in favor of `Camera2d` and `Camera3d`. Inserting them will now also insert the other components required by them automatically. |

Migrate meshes and materials to required components (#15524)
# Objective A big step in the migration to required components: meshes and materials! ## Solution As per the [selected proposal](https://hackmd.io/@bevy/required_components/%2Fj9-PnF-2QKK0on1KQ29UWQ): - Deprecate `MaterialMesh2dBundle`, `MaterialMeshBundle`, and `PbrBundle`. - Add `Mesh2d` and `Mesh3d` components, which wrap a `Handle<Mesh>`. - Add `MeshMaterial2d<M: Material2d>` and `MeshMaterial3d<M: Material>`, which wrap a `Handle<M>`. - Meshes *without* a mesh material should be rendered with a default material. The existence of a material is determined by `HasMaterial2d`/`HasMaterial3d`, which is required by `MeshMaterial2d`/`MeshMaterial3d`. This gets around problems with the generics. Previously: ```rust commands.spawn(MaterialMesh2dBundle { mesh: meshes.add(Circle::new(100.0)).into(), material: materials.add(Color::srgb(7.5, 0.0, 7.5)), transform: Transform::from_translation(Vec3::new(-200., 0., 0.)), ..default() }); ``` Now: ```rust commands.spawn(( Mesh2d(meshes.add(Circle::new(100.0))), MeshMaterial2d(materials.add(Color::srgb(7.5, 0.0, 7.5))), Transform::from_translation(Vec3::new(-200., 0., 0.)), )); ``` If the mesh material is missing, previously nothing was rendered. Now, it renders a white default `ColorMaterial` in 2D and a `StandardMaterial` in 3D (this can be overridden). Below, only every other entity has a material:   Why white? This is still open for discussion, but I think white makes sense for a *default* material, while *invalid* asset handles pointing to nothing should have something like a pink material to indicate that something is broken (I don't handle that in this PR yet). This is kind of a mix of Godot and Unity: Godot just renders a white material for non-existent materials, while Unity renders nothing when no materials exist, but renders pink for invalid materials. I can also change the default material to pink if that is preferable though. ## Testing I ran some 2D and 3D examples to test if anything changed visually. I have not tested all examples or features yet however. If anyone wants to test more extensively, it would be appreciated! ## Implementation Notes - The relationship between `bevy_render` and `bevy_pbr` is weird here. `bevy_render` needs `Mesh3d` for its own systems, but `bevy_pbr` has all of the material logic, and `bevy_render` doesn't depend on it. I feel like the two crates should be refactored in some way, but I think that's out of scope for this PR. - I didn't migrate meshlets to required components yet. That can probably be done in a follow-up, as this is already a huge PR. - It is becoming increasingly clear to me that we really, *really* want to disallow raw asset handles as components. They caused me a *ton* of headache here already, and it took me a long time to find every place that queried for them or inserted them directly on entities, since there were no compiler errors for it. If we don't remove the `Component` derive, I expect raw asset handles to be a *huge* footgun for users as we transition to wrapper components, especially as handles as components have been the norm so far. I personally consider this to be a blocker for 0.15: we need to migrate to wrapper components for asset handles everywhere, and remove the `Component` derive. Also see https://github.com/bevyengine/bevy/issues/14124. --- ## Migration Guide Asset handles for meshes and mesh materials must now be wrapped in the `Mesh2d` and `MeshMaterial2d` or `Mesh3d` and `MeshMaterial3d` components for 2D and 3D respectively. Raw handles as components no longer render meshes. Additionally, `MaterialMesh2dBundle`, `MaterialMeshBundle`, and `PbrBundle` have been deprecated. Instead, use the mesh and material components directly. Previously: ```rust commands.spawn(MaterialMesh2dBundle { mesh: meshes.add(Circle::new(100.0)).into(), material: materials.add(Color::srgb(7.5, 0.0, 7.5)), transform: Transform::from_translation(Vec3::new(-200., 0., 0.)), ..default() }); ``` Now: ```rust commands.spawn(( Mesh2d(meshes.add(Circle::new(100.0))), MeshMaterial2d(materials.add(Color::srgb(7.5, 0.0, 7.5))), Transform::from_translation(Vec3::new(-200., 0., 0.)), )); ``` If the mesh material is missing, a white default material is now used. Previously, nothing was rendered if the material was missing. The `WithMesh2d` and `WithMesh3d` query filter type aliases have also been removed. Simply use `With<Mesh2d>` or `With<Mesh3d>`. --------- Co-authored-by: Tim Blackbird <justthecooldude@gmail.com> Co-authored-by: Carter Anderson <mcanders1@gmail.com> |

Migrate lights to required components (#15554)
# Objective Another step in the migration to required components: lights! Note that this does not include `EnvironmentMapLight` or reflection probes yet, because their API hasn't been fully chosen yet. ## Solution As per the [selected proposals](https://hackmd.io/@bevy/required_components/%2FLLnzwz9XTxiD7i2jiUXkJg): - Deprecate `PointLightBundle` in favor of the `PointLight` component - Deprecate `SpotLightBundle` in favor of the `PointLight` component - Deprecate `DirectionalLightBundle` in favor of the `DirectionalLight` component ## Testing I ran some examples with lights. --- ## Migration Guide `PointLightBundle`, `SpotLightBundle`, and `DirectionalLightBundle` have been deprecated. Use the `PointLight`, `SpotLight`, and `DirectionalLight` components instead. Adding them will now insert the other components required by them automatically. |

Refactor BRP to allow for 3rd-party transports (#15438)
## Objective Closes #15408 (somewhat) ## Solution - Moved the existing HTTP transport to its own module with its own plugin (`RemoteHttpPlugin`) (disabled on WASM) - Swapped out the `smol` crate for the smaller crates it re-exports to make it easier to keep out non-wasm code (HTTP transport needs `async-io` which can't build on WASM) - Added a new public `BrpSender` resource holding the matching sender for the `BrpReceiver`' (formally `BrpMailbox`). This allows other crates to send `BrpMessage`'s to the "mailbox". ## Testing TODO --------- Co-authored-by: Matty <weatherleymatthew@gmail.com> |

Initial implementation of the Bevy Remote Protocol (Adopted) (#14880)
# Objective Adopted from #13563. The goal is to implement the Bevy Remote Protocol over HTTP/JSON, allowing the ECS to be interacted with remotely. ## Solution At a high level, there are really two separate things that have been undertaken here: 1. First, `RemotePlugin` has been created, which has the effect of embedding a [JSON-RPC](https://www.jsonrpc.org/specification) endpoint into a Bevy application. 2. Second, the [Bevy Remote Protocol verbs](https://gist.github.com/coreh/1baf6f255d7e86e4be29874d00137d1d#file-bevy-remote-protocol-md) (excluding `POLL`) have been implemented as remote methods for that JSON-RPC endpoint under a Bevy-exclusive namespace (e.g. `bevy/get`, `bevy/list`, etc.). To avoid some repetition, here is the crate-level documentation, which explains the request/response structure, built-in-methods, and custom method configuration: <details> <summary>Click to view crate-level docs</summary> ```rust //! An implementation of the Bevy Remote Protocol over HTTP and JSON, to allow //! for remote control of a Bevy app. //! //! Adding the [`RemotePlugin`] to your [`App`] causes Bevy to accept //! connections over HTTP (by default, on port 15702) while your app is running. //! These *remote clients* can inspect and alter the state of the //! entity-component system. Clients are expected to `POST` JSON requests to the //! root URL; see the `client` example for a trivial example of use. //! //! The Bevy Remote Protocol is based on the JSON-RPC 2.0 protocol. //! //! ## Request objects //! //! A typical client request might look like this: //! //! ```json //! { //! "method": "bevy/get", //! "id": 0, //! "params": { //! "entity": 4294967298, //! "components": [ //! "bevy_transform::components::transform::Transform" //! ] //! } //! } //! ``` //! //! The `id` and `method` fields are required. The `param` field may be omitted //! for certain methods: //! //! * `id` is arbitrary JSON data. The server completely ignores its contents, //! and the client may use it for any purpose. It will be copied via //! serialization and deserialization (so object property order, etc. can't be //! relied upon to be identical) and sent back to the client as part of the //! response. //! //! * `method` is a string that specifies one of the possible [`BrpRequest`] //! variants: `bevy/query`, `bevy/get`, `bevy/insert`, etc. It's case-sensitive. //! //! * `params` is parameter data specific to the request. //! //! For more information, see the documentation for [`BrpRequest`]. //! [`BrpRequest`] is serialized to JSON via `serde`, so [the `serde` //! documentation] may be useful to clarify the correspondence between the Rust //! structure and the JSON format. //! //! ## Response objects //! //! A response from the server to the client might look like this: //! //! ```json //! { //! "jsonrpc": "2.0", //! "id": 0, //! "result": { //! "bevy_transform::components::transform::Transform": { //! "rotation": { "x": 0.0, "y": 0.0, "z": 0.0, "w": 1.0 }, //! "scale": { "x": 1.0, "y": 1.0, "z": 1.0 }, //! "translation": { "x": 0.0, "y": 0.5, "z": 0.0 } //! } //! } //! } //! ``` //! //! The `id` field will always be present. The `result` field will be present if the //! request was successful. Otherwise, an `error` field will replace it. //! //! * `id` is the arbitrary JSON data that was sent as part of the request. It //! will be identical to the `id` data sent during the request, modulo //! serialization and deserialization. If there's an error reading the `id` field, //! it will be `null`. //! //! * `result` will be present if the request succeeded and will contain the response //! specific to the request. //! //! * `error` will be present if the request failed and will contain an error object //! with more information about the cause of failure. //! //! ## Error objects //! //! An error object might look like this: //! //! ```json //! { //! "code": -32602, //! "message": "Missing \"entity\" field" //! } //! ``` //! //! The `code` and `message` fields will always be present. There may also be a `data` field. //! //! * `code` is an integer representing the kind of an error that happened. Error codes documented //! in the [`error_codes`] module. //! //! * `message` is a short, one-sentence human-readable description of the error. //! //! * `data` is an optional field of arbitrary type containing additional information about the error. //! //! ## Built-in methods //! //! The Bevy Remote Protocol includes a number of built-in methods for accessing and modifying data //! in the ECS. Each of these methods uses the `bevy/` prefix, which is a namespace reserved for //! BRP built-in methods. //! //! ### bevy/get //! //! Retrieve the values of one or more components from an entity. //! //! `params`: //! - `entity`: The ID of the entity whose components will be fetched. //! - `components`: An array of fully-qualified type names of components to fetch. //! //! `result`: A map associating each type name to its value on the requested entity. //! //! ### bevy/query //! //! Perform a query over components in the ECS, returning all matching entities and their associated //! component values. //! //! All of the arrays that comprise this request are optional, and when they are not provided, they //! will be treated as if they were empty. //! //! `params`: //! `params`: //! - `data`: //! - `components` (optional): An array of fully-qualified type names of components to fetch. //! - `option` (optional): An array of fully-qualified type names of components to fetch optionally. //! - `has` (optional): An array of fully-qualified type names of components whose presence will be //! reported as boolean values. //! - `filter` (optional): //! - `with` (optional): An array of fully-qualified type names of components that must be present //! on entities in order for them to be included in results. //! - `without` (optional): An array of fully-qualified type names of components that must *not* be //! present on entities in order for them to be included in results. //! //! `result`: An array, each of which is an object containing: //! - `entity`: The ID of a query-matching entity. //! - `components`: A map associating each type name from `components`/`option` to its value on the matching //! entity if the component is present. //! - `has`: A map associating each type name from `has` to a boolean value indicating whether or not the //! entity has that component. If `has` was empty or omitted, this key will be omitted in the response. //! //! ### bevy/spawn //! //! Create a new entity with the provided components and return the resulting entity ID. //! //! `params`: //! - `components`: A map associating each component's fully-qualified type name with its value. //! //! `result`: //! - `entity`: The ID of the newly spawned entity. //! //! ### bevy/destroy //! //! Despawn the entity with the given ID. //! //! `params`: //! - `entity`: The ID of the entity to be despawned. //! //! `result`: null. //! //! ### bevy/remove //! //! Delete one or more components from an entity. //! //! `params`: //! - `entity`: The ID of the entity whose components should be removed. //! - `components`: An array of fully-qualified type names of components to be removed. //! //! `result`: null. //! //! ### bevy/insert //! //! Insert one or more components into an entity. //! //! `params`: //! - `entity`: The ID of the entity to insert components into. //! - `components`: A map associating each component's fully-qualified type name with its value. //! //! `result`: null. //! //! ### bevy/reparent //! //! Assign a new parent to one or more entities. //! //! `params`: //! - `entities`: An array of entity IDs of entities that will be made children of the `parent`. //! - `parent` (optional): The entity ID of the parent to which the child entities will be assigned. //! If excluded, the given entities will be removed from their parents. //! //! `result`: null. //! //! ### bevy/list //! //! List all registered components or all components present on an entity. //! //! When `params` is not provided, this lists all registered components. If `params` is provided, //! this lists only those components present on the provided entity. //! //! `params` (optional): //! - `entity`: The ID of the entity whose components will be listed. //! //! `result`: An array of fully-qualified type names of components. //! //! ## Custom methods //! //! In addition to the provided methods, the Bevy Remote Protocol can be extended to include custom //! methods. This is primarily done during the initialization of [`RemotePlugin`], although the //! methods may also be extended at runtime using the [`RemoteMethods`] resource. //! //! ### Example //! ```ignore //! fn main() { //! App::new() //! .add_plugins(DefaultPlugins) //! .add_plugins( //! // `default` adds all of the built-in methods, while `with_method` extends them //! RemotePlugin::default() //! .with_method("super_user/cool_method".to_owned(), path::to::my:🆒:handler) //! // ... more methods can be added by chaining `with_method` //! ) //! .add_systems( //! // ... standard application setup //! ) //! .run(); //! } //! ``` //! //! The handler is expected to be a system-convertible function which takes optional JSON parameters //! as input and returns a [`BrpResult`]. This means that it should have a type signature which looks //! something like this: //! ``` //! # use serde_json::Value; //! # use bevy_ecs::prelude::{In, World}; //! # use bevy_remote::BrpResult; //! fn handler(In(params): In<Option<Value>>, world: &mut World) -> BrpResult { //! todo!() //! } //! ``` //! //! Arbitrary system parameters can be used in conjunction with the optional `Value` input. The //! handler system will always run with exclusive `World` access. //! //! [the `serde` documentation]: https://serde.rs/ ``` </details> ### Message lifecycle At a high level, the lifecycle of client-server interactions is something like this: 1. The client sends one or more `BrpRequest`s. The deserialized version of that is just the Rust representation of a JSON-RPC request, and it looks like this: ```rust pub struct BrpRequest { /// The action to be performed. Parsing is deferred for the sake of error reporting. pub method: Option<Value>, /// Arbitrary data that will be returned verbatim to the client as part of /// the response. pub id: Option<Value>, /// The parameters, specific to each method. /// /// These are passed as the first argument to the method handler. /// Sometimes params can be omitted. pub params: Option<Value>, } ``` 2. These requests are accumulated in a mailbox resource (small lie but close enough). 3. Each update, the mailbox is drained by a system `process_remote_requests`, where each request is processed according to its `method`, which has an associated handler. Each handler is a Bevy system that runs with exclusive world access and returns a result; e.g.: ```rust pub fn process_remote_get_request(In(params): In<Option<Value>>, world: &World) -> BrpResult { // ... } ``` 4. The result (or an error) is reported back to the client. ## Testing This can be tested by using the `server` and `client` examples. The `client` example is not particularly exhaustive at the moment (it only creates barebones `bevy/query` requests) but is still informative. Other queries can be made using `curl` with the `server` example running. For example, to make a `bevy/list` request and list all registered components: ```bash curl -X POST -d '{ "jsonrpc": "2.0", "id": 1, "method": "bevy/list" }' 127.0.0.1:15702 | jq . ``` --- ## Future direction There were a couple comments on BRP versioning while this was in draft. I agree that BRP versioning is a good idea, but I think that it requires some consensus on a couple fronts: - First of all, what does the version actually mean? Is it a version for the protocol itself or for the `bevy/*` methods implemented using it? Both? - Where does the version actually live? The most natural place is just where we have `"jsonrpc"` right now (at least if it's versioning the protocol itself), but this means we're not actually conforming to JSON-RPC any more (so, for example, any client library used to construct JSON-RPC requests would stop working). I'm not really against that, but it's at least a real decision. - What do we actually do when we encounter mismatched versions? Adding handling for this would be actual scope creep instead of just a little add-on in my opinion. Another thing that would be nice is making the internal structure of the implementation less JSON-specific. Right now, for example, component values that will appear in server responses are quite eagerly converted to JSON `Value`s, which prevents disentangling the handler logic from the communication medium, but it can probably be done in principle and I imagine it would enable more code reuse (e.g. for custom method handlers) in addition to making the internals more readily usable for other formats. --------- Co-authored-by: Patrick Walton <pcwalton@mimiga.net> Co-authored-by: DragonGamesStudios <margos.michal@gmail.com> Co-authored-by: Christopher Biscardi <chris@christopherbiscardi.com> Co-authored-by: Gino Valente <49806985+MrGVSV@users.noreply.github.com> |
