This PR cherry-picks some improvements from #63 that are general-purpose
and not specifically related to IK.
* Some logic has been added to `AppElement` to track the currently
selected Scene Element
* `disabled` property has been added to `ButtonElement`, with custom
styling and accessibility features
* Tagging entities with their `SceneElement` type has been made more
robust and reliable (previously, it was possible for all entities to
appear in the hierarchy as "Generic" elements depending on the order of
system execution)
Additionally:
* Forces the Netlify CI pipeline to always used the latest stable Rust
version
This PR exposes skeletal joint entities to the frontend hierarchy,
allowing the user to pose rigged models by selecting the joints and
transforming them.
Additionally, entity-type information (e.g., Mesh, Skeleton, Bone,
Light, etc.) has been added to the data structure passed to the
frontend, which is rendered with icons in the tree view.
This PR adds a WIP timeline UI for animating elements in the scene.
### Implemented Features
* The timeline can be panned with MMB and zoomed with Ctrl + Mouse Wheel
* The timeline can be "scrubbed" by dragging the red "play-head" with
LMB
* The timeline sidebar (displaying the list of tracks) can be resized by
dragging on the edge of the sidebar
* Keyframes can be added by pressing the "Add Keyframe" CTA in the UI
* Keyframes can be selected for editing by clicking the diamond-shaped
markers in the timeline
* Selected entities (including but not limited to keyframes) can be
deleted by pressing the "Delete" key
* Keyframes can be moved temporally by dragging the diamond-shaped
markers in the timeline
### Known issues
* Zooming the timeline in too far results in a soft-lock
* When zooming the timeline, the "transform origin" is currently
centered on the `00:00` timestamp. For ease of use, it should center on
the mouse cursor position instead.
* The timeline track-list is currently hard-coded to list the Camera and
Camera Target. Clicking on these entries currently serves no useful
purpose and may result in a crash.
* Keyframe markers in the timeline are not currently associated with
entries in the track-list and simply appear vertically centered in the
timeline view.
* Added keyframes currently record the position and orientation of the
scene camera when added, and are rendered in the world with debug
visualizations, but serve no useful purpose. Some design work is needed
(both user-experience and architectural) to decide on a workflow for
actually animating scene elements.
* Entity deletion cannot currently be undone/redone
This PR refactors the `studio` project's entry-point functions for
better maintainability and ease of use for local development.
### Overview
* `start_internal` refactored to return a `bevy::app::App` instead of
calling `App::run`, allowing for finer-grained configuration of unique
use cases
* Temporary `start` function added for WASM
* `init` function removed
* `main` standalone entry-point refactored to call `start_internal`
### Fixes
* Crash on non-WASM builds due to missing `StudioMode` resource
* Warning on non-WASM builds due to an unused variable
This commit implements a Sketchfab-style single-object viewer as a minimal
proof-of-concept.
### `@storyteller/studio-web`
This is a new package to house web components for interfacing with the
`@storyteller/studio` WASM library. It currently includes a single component,
`<sts-viewer />`, which is exported from `@storyteller/studio-web/viewer`.
### `react-frontend`
This is a new application intended as a proof-of-concept and testbed for React
interop with `@storyteller/studio-web`.
Web components are currently a little bit fiddly to use in a React application.
`react-frontend/src/app/studio-viewer.tsx` demonstrates how a React-idiomatic
component can be written as a thin wrapper around a web component, and
`react-frontend/src/app/app.tsx` demonstrates that wrapper component in use.
