Changelog

This changelog is manually updated. While an effort will be made to keep the Unreleased changes up to date, it may not be fully representative of the current state of the project.

Unreleased (YYYY-MM-DD)

Added

Headline features

  • Packages can now be depended on by ID and version (i.e. id = "viyiawgsl5lsiul6pup6pyv6bbt6o3vw", version = "0.3.2-nightly-2023-12-06") instead of by deployment. This is recommended for all future packages, as it makes it easier to understand which package is being used. See the package documentation for details.

Other

  • http::post has been added to the server API to make it possible to make POST requests. It accepts optional headers and body arguments.

Changed

Breaking

  • Ambient packages are no longer projected into Rust code using the #[main] macro. Instead, a build script is used to generate a src/packages.rs. The intent of this change is to make it obvious what's being generated and when, as well as making the macro less error-prone. To update for this:
    • Add pub mod packages; to the Rust modules with #[main].
    • Add ambient_package_projection as a build dependency in Cargo.toml.
    • Add build.rs to the project root with the following contents: 
      fn main() {
    ambient_package_projection::generate();
}
  • Ambient will no longer update the deployment field of dependencies; instead, it will insert the version of that dependency, and that version is not automatically updated. The new --version argument can be used to update the versions of every package in your dependency tree: ambient deploy --version 0.3.
  • http::get now accepts optional headers. To update your code, set None for the second argument.
  • File I/O and the http APIs are now disabled when used on a hosted environment (i.e. Ambient deployments). To test if your logic still works in a hosted environment, run Ambient with the AMBIENT_HOSTED environment variable set to anything (e.g. AMBIENT_HOSTED=1 ambient run).

Version 0.3.0 (2023-10-04)

This release involved a great many changes, including porting Ambient to the web, adding support for deployments, many API changes, and more. Not all changes may be reflected in this changelog; please let us know if you find any omissions.

Added

Headline features

  • Client: The client can now run on the web.
  • Deploy: The ambient deploy command can now be used to deploy a package to Ambient runtime services.
  • Audio: Spatial audio is now supported for 3D sounds. See the physics example and first_person_camera example
  • Networking: The networking protocol now supports WebTransport for the web client.
  • Rendering: Procedural meshes, textures, samplers and materials are now supported on the client. See the procedural generation example.
  • Semantics: A semantic system to connect packages (previously projects) has been added. This enables dependencies, enums and more. See the breaking changes for more details.

Other

  • UI: Added a new ImageFromUrl element, which can load images from assets or URLs. It also supports rounded corners, borders and a fallback background color. See the image example for more details.
  • Rendering: Added a torus primitive. Thanks to @mebyz for implementing this in #376!
  • Physics: Add set_character_controller_position to the physics API. Thanks to @devjobe for implementing this in #398.
  • ECS: Duration is now a supported primitive type.
  • ECS: All integer types from 8-bit to 64-bit are now supported as component types, including signed and unsigned variants. Additionally, all signed and unsigned integer vector types are now supported. This includes U16, IVec2, UVec3, etc.
  • Docs: The IDE documentation has been improved, including information on how to set up Emacs for Ambient development (thanks to @kevzettler in #505).
  • Assets: ambient assets import can be used to import assets one by one. This will create or modify the pipeline.toml file for you.
  • Camera: Added camera::get_active to get the active camera.
  • Client: When using the native client, you can now use --window-x and --window-y to specify the window position, as well as --window-width and --window-height to specify the window size.
  • Packages: A set of standard packages have been added. Explore guest/rust/packages to find them. These include a character controller, a focus-grabber, a package manager, and more.
  • Packages: Several sample games have been added, including tangent, arkanoid, pong, and more.
  • Examples: Examples have been added for new functionality, including clock, audio_ctrl, dependencies, and more.
  • Debugging: Sentry has been added to the client and server to automatically report crashes. This can be disabled in Ambient's settings.toml.

Breaking

  • Examples: Examples have been rearranged to be more discoverable. They are now grouped by category.

  • Project: Projects have been renamed to Packages; see the package documentation for details.

  • Package: As mentioned above, a new package semantic system has been added. This comes with several breaking changes:

    • In your Rust code:

      • The modules generated by the Ambient macro are now different in shape. They are namespaced, with each item being present in the namespace as a separate module within the packages module, where your package is this. For example:
        • components::my_component -> packages::this::components::my_component
        • ambient_api::components::core::app::main_scene -> ambient_api::core::app::components::main_scene
        • a dependency cool_dependency = { path = "somewhere" } -> packages::cool_dependency::components::my_component (i.e. the name used for the import is used, not the package ID)
      • asset::url has been removed; instead, each package now introduces an assets module, allowing you to access that package's assets directly. For example:
        • asset::url("assets/Teapot.glb").unwrap() -> packages::ambient_example_asset_loading::assets::url("Teapot.glb")
      • UI layout components now use enums to specify their alignment. For example:
        • with_default(fit_vertical_none()) -> with(fit_vertical(), Fit::None)
      • Messages now preserve the order of their fields.
        • If your fields are a, c, b, they will be in that order in the generated code.
        • Previously, they were sorted alphabetically.

    • In your ambient.toml:

      • Specifying a version is now mandatory.

      • Specifying a content is now mandatory.

      • Messages now have PascalCase IDs:

        • messages.set_controller -> messages.SetController

      • Enums are now supported; they are defined as follows, and can be used anywhere a primitive type can be used, including components and messages.

        [enums.Layout]
description = "The type of the layout to use."
[enums.Layout.members]
Flow = "Bottom-up flow layout."
Dock = "Top-down dock layout."
Bookcase = "Min-max bookcase layout."
WidthToChildren = "Width to children."

[components]
layout = { type = "Layout" }

      • Packages can now depend on other packages, allowing for access to their components, messages, etc. This is done by adding a dependencies section to your package. For example:

        [dependencies]
my_cool_package = { path = "cool_package" }

        This will allow you to access the components, messages, etc. of the my_cool_package package from your package. The name that you use to import the package will be used as the namespace, not the package's original ID.

  • Components: Several "tag components" have been prefixed with is_ to indicate their tag nature. These include:

    • core::animation::animation_player -> core::animation::is_animation_player
    • core::audio::audio_player -> core::audio::is_audio_player
    • core::audio::spatial_audio_player -> core::audio::is_spatial_audio_player
    • core::layout::screen -> core::layout::is_screen
    • core::network::persistent_resources -> core::network::is_persistent_resources
    • core::network::synced_resources -> core::network::is_synced_resources
    • core::player::player -> core::player::is_player
    • core::wasm::module -> core::wasm::is_module
    • core::wasm::module_on_server -> core::wasm::is_module_on_server

  • API: Locally-broadcasted messages can now choose to include the originating module in the broadcast; this is an additional boolean parameter to ModuleMessage::send_local_broadcast and message::Target::LocalBroadcast.

  • Camera: Renamed screen_to_world_direction to screen_position_to_world_ray and clip_space_ray to clip_position_to_world_ray. See #410.

  • Package: type = { type = "Vec3" } is no longer valid syntax in ambient.toml. Only type = "Vec3" and type = { type = "Vec", element-type = "Vec3" } are valid.

  • Physics: Renamed the visualizing component to visualize_collider.

  • Animation: The animation system has been reworked. See the animation documentation for details. Thanks to @devjobe for laying the foundation for this!

  • Physics: Renamed box_collider to cube_collider.

  • API: The time function has been split into game_time and epoch_time. The dtime component has been renamed to delta_time. The frametime function has been renamed to delta_time.

  • Assets: Asset pipelines now use TOML instead of JSON. Use the ambient assets migrate-pipelines-toml command to migrate. (Note that this command will be removed in the next release.)

  • API: Removed Entity::with_default due to its confusing behaviour (Rust defaults are not necessarily the same as component or concept defaults). You will now have to explicitly specify a value for each component.

  • API: entity::wait_for_component is now marked as must_use to ensure users consider the possibility of the entity being despawned.

  • Elements: All hooks are now free functions (i.e. use_state(hooks, ..) instead of hooks.use_state(..))

  • UI: Focus is now global across different packages, including the removal of the FocusRoot element component.

  • Hierarchies: The children component is now automatically derived from parent components (unless the user opts out of this). The children component is also no longer networked, as it is automatically derived on the client.

  • Concepts: Concept code generation has been changed to generate structs instead, as well as adding support for optional components. See the documentation for more information.

Non-breaking

  • Logging: The logging output levels have been tweaked to better communicate the state of the system at any given time.
  • Debugger: The debugger has been improved with a resizable sidebar, a scrollable view, and a component filter.
  • Animation: The animation graph is now executed on the server as well.
  • CLI: The ambient new command now takes several parameters to customize the resulting generation.
  • Rendering: The renderer now runs using the direct pipeline on all architectures. This is temporary until platform-specific issues with the multi-draw indirect pipeline are addressed.

Fixed

  • Rendering: Skinned meshes will no longer be corrupted when there is more than one skinned mesh in a mesh buffer.
  • UI: TextEditor will no longer capture input even when it is not visible.
  • Rendering: Decals now render more consistently.
  • API: entity::wait_for_component will now exit if the entity is despawned.
  • API: The message::Source methods no longer consume the source when returning their data.
  • Rendering: Lines with a from located after a to on the X-dimension will now render correctly.
  • API: The entity::mutate_component documentation now refers to the correct parameter. Thanks to @aldzban for fixing this in #482.
  • UI: The ScrollArea now has a scroll bar.
  • Input: Input is now cleared when the window loses focus, preventing "stuck input" bugs.
  • UI: Layout-related properties, like alignment and fit, did not work correctly for certain values. This has been fixed with the introduction of enums.
  • Player: Player entities are now recursively despawned when disconnecting.
  • Build: Rust compilation errors are now more readable with more colors and fewer unused warnings.
  • ECS: The transformable concept now includes local_to_world to ensure that the world transform is always available.
  • Physics: The physics::raycast[_first] functions will now validate the direction to ensure that they are non-zero, non-NaN and normalized.
  • Rendering: Removing the outline_recursive component from a entity will now remove the outline from its children as well.
  • API: The ambient_ui prelude (and the ambient_api prelude, by extension) no longer glob-imports components into the global namespace. This means that you will need to import components explicitly.
  • Messaging: Messages without empty fields now generate a unit struct, instead of a struct with no fields. That is, they generate struct MyMessage; instead of struct MyMessage {}.
  • Physics: Child collision volumes are now automatically updated when their parent's transform changes. Thanks to @kevzettler for fixing this in #885!
