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)
We're abusing their v4 API implementation to make v5 API requests, which might not work; hopefully the authentication scheme is the same.
Furthermore, I'm assuming that the v4 sign response gives you a version ID that is valid for v5 `/addons/addon` requests.
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.
It's possible to call 'start()' on a timer
that has currentCount >= repeatCount. This will
cause the timer to tick exactly once, and then stop agian.
We were incorrectly reporting 'timer.running' in such a scenario:
'running' should be reported as 'true' up until just before the
'TimerEvent.TIMER_COMPLETE' is fired.
This fixes gaining money from bloon popping / level completion
in BTD5.
Depending on when loading completes, calling
`catchup_display_object_to_frame` might trigger an
`addedToStageEvent` inside the loaded SWF. The event listener
will expect the SWF content to have 'DisplayObject.stage' accessible,
so we need to make sure that we've added our loaded content as
a child of the `Loader` *before* any event handlers run.
I've been unable to come up with a self-contained test for this,
but it's necessary for Bloons Tower Defense 5
Previously, the Vector$ classes were only exported in the internal 'AS3.vec' namespace, which is used by older ActionScript code. However, newer ActionScript code can also access these classes through the public 'AS3.vec' namespace, via 'getDefintionByName'.
We now export these classes in both namespaces. In the public 'AS3.vec' namespace, they are exported like 'Vector.' instead of 'Vector$uint'
