Doing `super.someNonGetter` gives you back a function object.
We were previously attempting to call normal methods as though
they were getters. Additionally, we were failing to properly
get the property from the superclass vtable.
This ensures that we call the normal Array concat method
(or a method that overrides it). Some SWFs may define a *public*
concat method in an Array subclass, with a different signature.
Fixes#10552
1. toString and toLocaleString should only be defined on the prototype.
2. concat should only be defined as an as3 and proto property, not as an instace property.
3. Array doesn't have a valueOf defined directly on it.
This matches the Context3D docs. Calling 'present' swaps
the buffers.
I wasn't certain if we actually need a double-buffered depth
texture, but I included one just to be safe.
Now that most of the complicated Context3D methods have been
implemented, we can simplify the overall design. Instead of queueing
up commands and having `present` execute them in a loop, we
can execute each command immediately. The key insight is that
a `RenderPass` is only needed for `DrawTriangles`, so we don't
have to store it in `Context3D` and deal with complicated lifetime
issues.
The old behavior gave us implicit double-buffering behavior,
since nothing would get rendered until a 'present' call.
Now that a 'drawTriangles' call will immediately submit
a draw command, we need to implement actual double buffering.
This is done in the next commit.
The `Avm2::{dispatch, broadcast}_event` methods now log and swallow any
AVM2 error occuring during the dispatch, instead of repeating the
handling code for each caller.
This also introduces some behavioral changes:
- Errors messages are more consistent;
- For consistency with `broadcast_event`, `dispatch_event` panics if
given a non-event object to dispatch.
When we were using a fork of quick-xml, we modified the actual
unescape method. Now that we're using the crates.io release again,
we need to go through our `custom_unescape` function.
If a SWF contains multiple DefineFont tags with the same
font name (but different font IDs), the first tag will win
when a font is looked up by *name*. This affects the behavior
of EditText objects, which can have embedded HTML like
`<font face="MyFontName">` which performs a font lookup by name.
This fixes Fancy Pants World 4 Part 3, which contains two
DefineFont3 tags with the name FancyFont. The second font is
missing many glyphs, so using it causes us to be unable to
render the squiggle and life count text.
These functions are intentionally no-ops in Ruffle because it has
no concept of a player dirty region, so unmark them as stubs.
The only observable difference is that Flash Player will sometimes
not re-render a `Bitmap` instance on the stage immediately if it's
`BitmapData` is locked and changed, but this is only temporary and
depends on the redraw behavior of the Flash Player.
* `global_to_local` returns `None` if the object has zero scale.
* Adjust AVM `globalToLocal` methods to return the untransformed
point on failure.
* Add `DisplayObject::mouse_to_local` to handle AVM `mouseX`
and `mouseY` coordinates. For zero scale objects, these end up
returning values based on the twips-to-pixels scale,
divided by 20.
* Add `Matrix::determinant`.
* Rename `Matrix::invert` to `inverse`.
* `Matrix::inverse` return an `Option`, with `None` returned
for non-invertible matrices.
* AMV `Matrix::invert` duplicates the code as the behavior is
different (works in f64 and not twips, etc.)
I've moved our special entity handling logic into
a `custom_unescape` function. This lets us move off
of our fork of `quick-xml` back onto the crates.io release
When we receieve a nonzero 'antiAlias' parameter, we create
create a non-multisampled resolve buffer to use with WGPU.
Several tests were already requesting antialiasing, so their
output images are now anti-aliased without any changes to
the tests themselves.
Previously, the `ApplicationDomain` constructor ignored its argument,
instead of constructing a new domain with the specified domain as
the parent.
Additionally, we were incorrectly executing code with
`Activation::from_nothing` in several places, causing
`ApplicationDomain.currentDomain` to return the system domain
instead of the correct parent domain. I've introduced a new method
`Activation::from_domain`, which allows explicitly passing in the
domain. Internally, we now store an `Option<Domain>`, and panic
when calling `caller_domain` with a `None` domain. Several places
in the codebase have been adjusted to pass in the correct domain.
If you use a `Loader` to load an SWF containing a class that shadows
an already-defined class, the class definition from the Loader SWF
will be ignoredin favor of the already-defined class. This commit
applies this log to symbol classes as well - the symbol registry for the class
should continue to point to the existing MovieClip in the parent.
This results in the child SWF instantiating the class from the parent
SWF when the child places the affected movie clip on the timeline.
This fixes a bug in Fancy Pants World 4 Part 3, where the sub-level
SWF was replacing the symbol class entry for the parent 'shipInteract'
class with the dummy clip provided in the sub-level SWF (instead
of continuing to use the correct clip from the parent SWF).
Instead of queueing up these events in the `Activation`,
we can fire them immediately by making `AudioManager::update_sounds`
a freestanding method that takes in an `UpdateContext`
Avoid panic in ChildContainer.replace_at_depth() panic when previous child is not in render list.

Previously, we were scaling down the source image to fit into
the smaller sourceRect, instead of cropping at the original scale.
This broke the background textures in Fancy Pants World 4 Part 2,
as the scaled-down output image resulted in a smaller rectangle
being returned from 'getColorBoundsRect'
We now crop the image by properly constructing the UV-coordinate
transformation matrix. We were also using the wrong value for the
'destPoint' y coordinate, which I fixed.
This slightly changes the image output of two tests - the new images
now more closely match the Flash output.
So far this just sticks the stream into the playback list and kicks off a download; we do not actually support decoding, seeking, or any of the other things that we expect `play` to do.
Calling `StreamManager::tick` advances all streams to the appropriate time. This is an unlocked timestep to support things like non-stage-FPS video and the like.
* Pixels with 0 alpha are not affected by color transforms.
* Color channels should be clamped to the 0-255 range.
* A color transform with only an alpha multiplier of >1 has no
effect.
These are used in the Rust handler, but were not correctly set in the AS bindings, leading to errors such as "Attempted to call flash::text::TextField::getTextFormat with 2 arguments (more than 0 is prohibited)"
In the process, I fixed a bug where we were clearing the depth
and stencil buffers with the incorrect value.
This makes Fancy Pants World 4 Part 1 playable to completion
(though there are still some rendering issues that need
to be fixed).
This factors out the early-resolution logic I added in `op_coerce`,
making it useable during paramter resolution as well. This lets
a static initializer reference the containing class in parameter
types, even though the ClassObject hasn't yet been initialized.
We were missing the initial 'set_skip_next_enter_frame(true)'
call, and we weren't properly clearing it in `enter_frame`.
Loaders appear to have the same behavior as MovieClips.
This makes us correctly run the first framescript for the loaded
SWF.
It was incorrectly declared as public method, which lead to
spurious 'missing override' errors in classes extending Array
that define a 'removeAt' method.
We don't need to perform a sync when getting the width/height,
getting or setting the 'disposed' status, or uploading to
a Context3D texture.
The Context3D change (using `copy_texture_to_texture` instead
of relying on the CPU pixels) has the added advantage of avoiding
a validation error when our source image row length isn't aligned
to `COPY_BYTES_PER_ROW_ALIGNMENT`
This dramatically speeds up the Fancy Pants World 4 loading time
(on a branch with my XML prs merged). Without this change, my
machine spends around 10 seconds on a blank white screen after
clicking 'Play'. With this change, the time spent on that screen
is reduced to around 1-2 seconds.
`SoundChannel.position` was being updated by the audio manager each
tick, but the Flash Player only updates and caches the position
when `SoundChannel.position` is accessed. In contrast, an AVM1
`Sound` will constantly update its position.
This means accessing `position` only once after a sound has
finished playing will return 0.
Fixes#9952.
Despite not being MovieClips, Loader instances appear to get
the same kind of orphan handling - you can instantiate a
Loader and call 'Loader.load' without ever adding it
to a parent, and the loader will still run.
I've changed the movie code to work with a new `DisplayObjectWeak`
enum. Currently, this just supports `MovieClip` and `Loader`,
but it can easily be extended if we ever need other weak display
objects.
This also fixes a bug where we were adding the loaded MovieClip
as a child of the Loader slightly too early.
This includes the 'GetDescendants' opcode, which is used by the
the 'xml..elementName' syntax. The 'XMLList.toXMLString()
impl makes it much easier to write tests for this.
None of these formats can currently be implemented
correctly with wgpu, so we just use Rgba8Unorm instead.
The handling of opaque compressed textures is a little
sketchy - it should work for 'normal' SWFs that upload
an opaque BitmapData, but we might need to manually
adjust the alpha values if
We only support values that are neither XML nor XMLList,
since we can't yet properly stringify those.
Attempting to modify an existing attribute throws an error.
* Bump bitflags to 2.0.0
* Sprinkle Clone, Copy, Eq, PartialEq, and Debug derives where needed
* Call `bits` on bitflags, as it is now a method
* Switch from `from_bits_truncate` to `from_bits_retain` on bitflags where needed
* Bump h263-rs for the bitflags 2.0.0 dependency
As part of porting to bitflags 2.0.0, see:
https://kodraus.github.io/rust/2022/10/07/bitflags2.html#upgrading-to-2x
We were ignoreing 'data32PerVertex'.
To make the code clearer, I've renamed the variable to
'data32_per_vertex', and made it a 'u8' (as it has a maximum of 64)
The XML call handler is implemented as 'new XML(arg)',
so we get all of the related string coercions for free.
Our various native tables are starting to get somewhat wasteful -
if we add any more, we might want to consider a more compact
representation.
When we skip running a frame for a MovieCilp, we skip all
of its children as well. However, this skip 'counts' as
a skip for any children that already wanted to skip their next
frame. For example, say we create three objects in ActionScript,
and arrange them like 'obj1 -> obj2 -> obj3'.
The first 'obj1.enter_frame' call will not run a new frame
for any of the objects, but next time, 'obj1.enter_frame'
will run a new frame for all of the objects.
This fixes jacksmith, which was missing a frame1-framescript
due to 'enter_frame' getting incorrectly run for a deeply
nested child.
If you call 'BitmapData.dispose()', any Bitmap objects using it will
continue to report the original 'width' and 'height' values to
ActionScript. The values only refresh if you explicitly do
'Bitmap.bitmapData = bitmapDataObject' (including with the same
object).
Fancy Pants Adventure World 4 relies on this - it calls
BitmapData.dispose(), and then uses the width and height from
a previously-constructed Bitmap object.
When a DisplayObject is removed from its parent by a RemoveTag, it still runs its framescript for the current frame (but with 'this.parent == null'). It then stops executing entirely, unlike ActionScript-removed orphans, which continue to execute indefinitely.
Additionally, objects created by ActionScript during a frame skip their next 'enterFrame' logic (but still receive an enterFrame event). This results in the currentFrame lagging one frame behind objects that were placed by the timeline during the same frame.
The combination of these two changes lets us greatly simplify frame lifecycle handling for orphan movies. Most of the orphan stages were unencessary, and the remaining ones run in the same phase as the normal Stage-descendant objects.
Webgl doesn't support BGRA textures, so this lets us use
Stage3D textures on the web backend. As a bonus, this speeds up
uploading an BitmapData to a Context3dTextureFormat.BGRA texture,
since we no longer need to change the format before copying.
This makes Solarmax2 playable on the web backend.
The stage alignment settings viewport_scale_factor should *not* be
applied to `Stage.transform.matrix`, which is only ever changed
as a result of explicit modification from ActionScript. Instead,
alignment and scaling are performed a separate step, which is
transparent to ActionScript.
I've implemented this through a new `viewport_matrix` field,
which is used during stage rendering and mouse coordinate
transformation.
This makes Stage3D instances properly scale - previously, they
would render unscaled. The linux standalone Flash Player doesn't
seem to use HiDPI mode, so I didn't realize that this was a bug
until now.
In the process of implementing this, I discovered and fixed a bug
with how we handle changing the viewport size under winit.
Calling `self.window.set_inner_size` does not immediately take
effect (at least on X11) - calling `self.window.inner_size()`
will report the old size until the next resize event.
Since build our Stage matrices from `self.window.inner_size()`
(and start running the SWF) immediately after `RuffleEvent::OnMetadata`,
we would run a few SWF frames with an incorrect viewport size. This
is visible to SWFs that have the scale mode set to "noScale", and
could break SWFs that expect the initial viewport size to be
the movie size. I've fixed this by delaying SWF execution until
we get a Resize event (if `self.window.inner_size()` does not
immediately report the size we set).
This makes #3294 (rollercoaster-creator-2) fully playable.
Missing is any (*) matching for child()/elements() and the existing attributes() method.
Also missing is support for number indexes with child().
When an XML object has simple content, you can call non-XML
methods directly on it - it will internally be stringified,
and the method will be called on the resulting string.
This lets `new XML("<p>Some content</p>".split(' ')` work.
Similarly, an XMLList object with a single XML child will
forward non-XML method calls to that object.
This PR implements this logic (based heavily on avmplus)
I've also renamed these methods to 'avm1_unload' and
'avm1_removed', to make it clear that they don't
apply to AVM2.
This was causing us to incorrectly skip mouse picks,
and remove masks.
I think this might have been broken by
https://github.com/ruffle-rs/ruffle/pull/9506, but we didn't have
proper test coverage.
If we execute a 'coerce' opcode for a class while it's being
initialized (which can happen by running a method from a static
initializer), we'll be unable to resolve the ClassObject using
`resolve_type`.
This is the only case where this can happen - any
superinterfaces/superclass will already be fully initialized
when we're running a class initializer. Therefore, we can
try to lookup the class from the `Domain`, and check if it
directly matches the class of the object we're coercing
(ignoring superclasses and interfaces).
This doesn't perfectly match Flash's behavior - I haven't been
able to reproduce the values produces when the DisplayObject
starts out with certain 'Matrix' values (a non-zero 'b' or 'd').
Howver, when the 'b' and 'd' matrix values are both 0, setting
'dobj.rotation = NaN' has no effect on the matrix, while
'dobj.scaleX = NaN' and 'dobj.scaleY = NaN' both treat 'NaN'
as 0 for the purposes of updating the matrix.
This fixes the tack shooter in Bloons Tower Defense 3, which
tries to set 'rotation = NaN' for spawned tacks.
This is necessary to make Steambirds get past the preloader screen.
All of the previous tests continue to pass with this change.
This commit modifies the existing test to start from within
the symbol_class constructor, instead of a frame script. In
this situation, a freshly-created orphan with a framescript will
run directly after the constructor returns, *before* an enterFrame
handler for the same orphan. I've verified that this modified test
fails without my change.
