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.
