`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.
This event fires for new clips before any construct clip events.
Split the action queue up into separate priorities, giving
initialize the highest priority.
If a masker is placed inside a masker, the inner mask is inactive
and instead renders as normal art, masked by the outer mask. Properly
handle this case by only pushing new masks if we are not currently
drawing the mask stencil.
Maskee inside maskee still functions as expected. (i.e., a clip
using a mask is masked itself).
This is the same way that AVM1 actions run and it appears that frame scripts work exactly the same way. It fixes all outstanding bugs with movie clip navigation in AVM2 and allows me to remove a lot of weird workarounds I was writing for the old, incorrect behavior.
I'm also removing the "last run script frame" rule as `run_frame_internal` already had rules to prevent stopped clips from rerunning actions.
