Our AVM2 `SharedObject` support is now *almost* equivalent
to our avm1 `SharedObject` support. We implement serialization
and deserialization for primitives, arrays, and `Object` instances
with local properties. We also implement serialization for `Date`,
but not `Xml` (since our AVM2 `Xml` class is just a stub at the moment).
This is enough to make 'This is the only level too' save level
progress to disk.
Currently, we always serialize to AMF3. When we implement
the `defaultObjectEncoding` and `objectEncoding`, we'll need
to adjust this.
* avm2: Implement `BitmapData.draw` for `wgpu` backend
This method requires us to have the ability to render directly to a
texture. Fortunately, the `wgpu` backend already supports this in
the form of `TextureTarget`. However, the rendering code required
some refactoring in order to avoid creating duplicate `wgpu` resources.
The current implementation blocks on copying the pixels back
from the GPU to the CPU, so that we can immediately set them in
the Ruffle `BitmapData`. This is likely very inefficient, but will
work for a first implementation.
In the future, we could explore allowing the CPU image data and GPU
texture to be out of sync, and only synchronized when explicitly
necessary (e.g. on `getPixel` or `setPixel` calls).
* Rename `with_offscreen_backend` to `render_offscreen` and use Bitmap
* Don't panic when backend doesn't implement `render_offscreen`
The current 'setInterval/setTimeout' implementation is
moved to 'core/src/timers.rs', and now works with both
AVM1 and AVM2 objects. The `flash.utils.Timer` class is implemented
mostly in ActionScript, with minimal modifications to the actual
Ruffle timer code.
`core` already depends on the `instant` crate which abstracts
`std::instant::Instant` and polyfills it on Web. Use it to replace
`NavigatorBackend::time_since_launch` in order to make `NavigatorBackend`
a little smaller and more simple.
Previously there were 3 implementations of `LocaleBackend`:
`DesktopLocaleBackend`, `WebLocaleBackend` and `NullLocaleBackend`.
While `DesktopLocaleBackend`, `WebLocaleBackend` were identical,
`NullLocaleBackend` always returned a fixed date/time for tests
determinism.
Unify them in a single file, and use `cfg!(test)` and a new dedicated
`deterministic` feature to decide whether to mock date/time or not.
This should not cause any behavioral changes.
Fix various issues with `SoundChannel`:
* Change `avm2::Object::as_sound_instance` to `as_sound_channel`.
* Cache sound position in `SoundChannelObject`.
* `SoundInfo::in_sample` is in units of 44100Hz.
* Clamp `num_loops` to 1.
Neither of these impls are actually used.
As a result of this change, several fields in `avm2::Activation` became
unused. I assumed that these fields will become used as more of avm2 is
implemented, so I suppressed the warnings for now
This unifies the code path for event sounds and stream sounds.
Both `AudioBackend::start_stream` and `start_sound` return a
`SoundHandle`. `stop_stream` is removed (`stop_sound` can be
used for both cases).
Also removes references to `CharacterId` from the `AudioBackend`
(instead, an increasing ID is returned to identiy streams while
loading).
Add an AudioManager struct to handle this list of actively playing
sounds. This will maintain information for each sound instance,
such as the owning display object, AVM1 object, etc.
This will allow us to implement the awkward AVM1 Sound API in a
fairly backend-agnostic way.
Player::background_color is now an Option. SetBackgroundColor will
change the background color of the player only when this is None,
i.e. only if no background color has yet been set.
This matches the behavior of the offical Flash Player, for example,
if a parent SWF is missing a SetBackgroundColor tag and loads a
child SWF, the child SWF's SetBackgroundColor tag takes effect.
This is anticipating adding a `bgcolor` option to the web builds,
allowing the HTML embed to override the bgcolor.
