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.
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.
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.
We were checking for byte length == 1 instead of # of characters
to determine if a keyboard key was a single printable character.
Thanks to @JMcKiern for pointing this out.
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.
An issue with Arena::clear allowed stale sound instance indices
to be remain valid, causing certain sounds to be removed when they
shouldn't (#1315). Workaround this issue by forcing Arena to bump
the generational index.
Sounds were not being removed from the instance list when they
completed playing. This could also cause StartSound tags with
NoMultiple set to not play, because the previous sound was presumed
to be playing.
Fixes part of #1245.
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.
Change `ActionGetTime` (`getTimer`) to use a new backend method.
This allows it to return updated times if it is called multiple
times in a single frame. This fixes hangs caused by games that use
busy-loop "frame limiter" code.
It doesn't feel like Flash without having the hand cursor display
when hovering over buttons. First pass at implementing this;
core communicates which mouse cursor to use via
`InputBackend::set_mouse_cursor`.
TODO: Hand cursor only displayed for Button display objects
currently. Movie clips should also display this when they are in
"button mode" (when a button mouse event is set on them in AVM1,
or `buttonMode` property in AVM2).
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.
Due to some strangeness with the way Rust implemented unsafe-to-move behavior, boxed futures are implicitly `Unpin`. Which is useless to us.
The reason for this is a little counter-intuitive. Actually, the fact that Rust supports memory pinning at all is a little odd, because the core language explicitly requires all types be movable. To get around this, Pin requires that all !Unpin types be *born pinned*. This is because you can't re-pin an already unpinned value in memory.
Anyway, this necessitates this silly API change.
The endTime parameter of AudioParam.linearRampToValueAtTime is
on the global AudioContext's timeline, not local to the sound.
Adding the sound's start time to the parameter fixes sound
envelopes not playing back correctly.
`AudioBuffer.copyToChannel` does not work on Safari, so switch to
using `getChannelData` to fill the audio buffers.
Limitations in wasm-bindgen prevent us from actually modifying the
data returned by `getChannelData` on the Rust side, so import a JS
function to fill the audio buffer (js-src/ruffle-imports.js).
When a stream sound uses ADPCM compression, the ADPCM header is
included in each SoundStreamBlock (as opposed to stream sounds
in the other formats). This header wasn't being parsed, resulting
in corrupted audio (see https://homestarrunner.com/main12.swf).
Converts the Bitmap character to a proper display object. This can
be instantiated directly in a PlaceObject tag in SWFv9 movies,
compared to the previous versions which indirectly references
bitmaps from Shape tags.
The text bounds fields for a DefineFont2/3 tag can be a bogus empty
rectangle, per the SWF spec. We must properly the bounds ourselves
to render properly on web.
Many SWFs use "hairline" strokes which are 1 twip wide, but Flash
renders strokes with a minimum width of 1 pixel (20 twips).
SVG has no minimum, resulting in faint lines for the "hairline"
strokes. Clamp the minimum stroke width to 1 pixel to more closely
match the Flash Player.
On the web demo, if you played two different SWFs, color transforms
would stop working because the color matrix SVG filter would be
created twice with the same ID. Now we properly remove the previous
filter.
Renamed `AudioBackend::play_sound` to `start_sound`, and this
also takes a `SoundInfo` parameter with the event sound settings
from the SWF file.
Desktop now obeys the loop and start/end point settings. Envelopes
are still TODO.
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.
DefineBitsJPEG3 tags also include a zlib-encoded alpha channel.
This wasn't working on web (it was trying to use the raw RBGA also
an image!) Now these are re-encoded to PNG.
Addresses #27.
Player is now in charge of scaling/cropping/translating the content
to fit the viewport size supplied by the frontend.
Added backend::render::Letterbox, which stores the margin sizes
for letter/pillarboxing.
Firefox would fudge with the dimensions of the SVG when we tried
to draw a scaled SVG to the canvas. Disabling preserveAspectRatio
prevents that. Fixes part of #24.
Firefox required the color matrix filter to be inside and <svg>
tag. Also, set color-interpolation-filters to sRGB to ensure
color transforms match Flash's output.
DefineBitsJPEG tags can have some extraneous bytes inside the
stream. Splice these out when decoding the JPEG.
TODO: Docs say this should only happen for SWF versions before 8?
Switch from pixels to twips for internal calculations. swf crate
was updated to add a Twips wrapper-type. Ruffle will use this type
internally for transforms and shapes. This fixes some precision
errors in rendering (see heroes_of_cybertron.swf) and will match
what the Flash Player does internally more closely. (e.g.
DisplayObject x and y will be quantized to 1/20 pixel units). It
is up to the renderer to convert units from twip space to pixels
when rendering.
