When reading an SWF, search for FileAttributes and
SetBackgroundColor and return this along with the header data
because it's useful (in particular, the AS3 flag).
* Remove all unwraps from web/lib.rs.
* Add convenience methods for grabbing the Ruffle web instance.
These methods also avoid panics/unwraps when borrowing
`RefCell`/`Mutex`.
* Use `warn_on_error` to avoid unwraps from web APIs.
Add `RufflePlayer.metadata` that exposes the SWF header fields to
JavaScript.
Add `RufflePlayer.readyState` and fire a `loadedmetadata` event
once the metadata is available, mimicking the HTML5 media APIs.
Since 19034b7, clip event scripts are returned as slices from the
SWF. This caused a panic when a movie was loaded into a clip,
because the loaded clip's `movie` would be used as the source for
clip events. However, clip events are placed by the parent's
PlaceObject tags, so the movie in this case should be the parent's
movie.
Fixes#2870.
Add `backgroundColor` setting to the config options, allowing
a user to override the background color of an SWF. The polyfill
will now look for the `bgcolor` HTML attribute on the embed
and fill in this setting appropriately.
Player::set_letterbox can be used to control the letterbox behavior.
* Letterbox::Off => no letterbox (flash behavior)
* Letterbox::Fullscreen => letterbox only in fullscreen (web default)
* Letterbox::On => always letterbox (desktop default)
Fix part of #2092. A panic could occur if content navigated away
using getURL, which could trigger the shared object flush while
the frame was still executing. Move the flush to "unload" so that
it occurs after execution is complete.
Previously, has_focus has been set to false upon window click, and
to true upon canvas click.
However, the canvas didn't receive click events when the context
menu was clicked, so fullscreen toggle led to focus loss.
Listening to player click events receives both canvas and context
menu clicks.
PanicInfo::payload wasn't giving anything useful (just resulted
in 'Unknown error') -- to_string displays all of the message,
payload, and location of the panic. Particularly the location
is helpful.
Adds a suspend_audio method to compliment prime_audio on WebAudioBackend, as well as logic in player.rs on the set_is_playing method to suspend audio when is_playing is set to false. Exposes pause method for the ruffle player in JavaScript with logic to display the play button when paused.
same_item_push was added on nightly, but is currently throwing
a false negative. I added an allow for it, but this causes a
warning on stable for an unknown lints, so allow unknown lints for
now.
During the small period of time when a player is created but has no root movie, a temporary empty movie is installed with an assumed stage size and framerate of 550x400@12fps. This is Flash default for new projects, so it seemed appropriate. User ActionScript cannot see these values, and I'm not even sure JavaScript can, either.
Don't call `render` from `Player::tick`; instead, require the
frontends to explicitly call `render` when they wish to redraw.
The frontend can query `Player::needs_render` to see if the stage
is dirty and needs a redraw. Update desktop and web to use this
new method.
This fits better with the newer winit event loop model, which
requires explicitly calling `request_redraw`, and should avoid
spurious renders.
This allows the formation of `'static` futures that can still interact with a player. Async code will need to upgrade the weak reference in order to be able to interact with the player.
Previously Performance.now() was used to grab the initial timestamp
for calculating dt in requestAnimationFrame. However, this doesn't
seem to be reliable and resulted in negative dt values in Chrome.
Now we just use an Option for the timestamp and initialize it to None.
The first animation callback will set the timestamp.
