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.
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'
We still want to propagate these hits to the parent, which may
be able to handle them. My existing tests missed this case,
since all of the parent objects had content which was
behind the child content. When the only clickable content
comes from a child with 'mouseEnabled=false', we should
still fire an event targeting the parent (when applicable
based on the parent's flags).
This fixes dragging on the background (without any scenery present)
in Steambirds.
When a MovieClip is an 'orphan' (it has no parent),
it still has frames run (including frame scripts). Some SWFS
like SteamBirds and 'This is the Only Level TOO' rely on this behavior,
so we need to implement it.
The overall idea is straightforward - we keep a global list of
orphan movies, which we add to whenever we unset the parent for a movie.
This list stores weak references for consistency with Flash.
When we run a frame, we process entries in the root movie list,
in addition to the normal recursive processing from the `Stage`.
However, exactly matching Flash's output turned out to be quite tricky.
The particular sequence of calls I make in `run_all_phases_avm2` makes Ruffle
pass two complicated test cases, but there could still be lurking bugs.
This is enough to get SteamBirds to the first level (which doesn't
render due to a different error).
We were previously performing a redundant 'self.hit_test_shape'
call in 'avm2_mouse_pick'. All of the logic in that function
is handled in `avm2_mouse_pick.` Additionally, this call happened
before we tested out children, which would result in us targeting
a parent's drawing instead of aa child.
Surprisingly, Flash allows mutliple classes in an inheritance chain
to hav a linked `class_symbol`. When we instantiate a `DisplayObject`,
we need to stop at the first such `class_symbol` we find. This means
that any fields set from named children will *only* be set in the
first class we find, not in any of the parent classes (as their
corresponding library symbol will not be instantiated).
Previously, we would continue looping even after we found a
`class_symbol`, resulting in the furthest ancestor *winning*
the `set_object2` call.
This is a very large diff, but most of it comes from test files and
output.
This PR ads partial support for the following Stage3D shader features:
* Normal (square), rectangle, and cube textures
* Varying and temporary registers
* Lots of opcodes
The combination of these allows us to get a raytracing program
fully working in Ruffle. I've included it as image test.
Currently, this test is very slow (about 90 seconds on my machine),
as the code I'm using (https://github.com/saharan/OGSL) includes
its own shader language and compiler. THe raytracing demo
first compiles its own shader language to AGAL, and then starts
rendering the scene.
Limitations:
* Many opcodes are still unimplemented
* Most non-default texture options (e.g. mipmaps) are not implemented
We were previously calling `get_property` to determine if a `toJSON`
property exists, but that produces an error if the method is missing
on a sealed class.
Additionally, JSON serialization wasn't taking into account properties
from the vtable. All public properties (including fields, const fields,
and getter methods) get serialized.
Unfortunately, our vtable property order currently doesn't match
Flash's. I've hand-edited the test output for now (all of the actual
properties are there, just in a different order), and added a note
This includes all of the XML elements described in 'describeType' docs.
Unfortunately, the order of elements produced by Flash depends on
the iteration order of internal hashtables. As a result, the test
manually stringifies an XML object, sorting the stringified children,
to produce consistent output between Flash and Ruffle.
This requires the ability to do a limited 'set_property',
as well as `get_enumerant_value`.
To prevent modification of XMLLists derived from queries,
I've introduced a `target` field on `XMLList`. This is
`None` for lists created with `new XMLList()`, and `Some`
when the list was derived from a query on an existing `XML`
/`XMLList`. We only allow `set_property` when `target` is `None`:
this is enough for filtering to work, and prevents silent incorrect
execution when trying to modify an existing node.
When rendering to an offscreen texture for `Bitmapdata.draw`,
we first render to a temporary frame buffer, and then copy the contents
of the frame buffer back to the target texture. However, this results
in blend modes being incorrectly applied - for example, rendering with
BlendMode.SUBTRACT will subtract against the framebuffer (which starts
with each pixel as 0x00000000), instead of the previous BitmapData
contents.
To fix this, we now use our texture target as the frame buffer
when performing `render_offscreen`. This ensure that we blend
over existing pixels (taking into account the `blendMode` provided
in the `BitmapData.draw` call).
When multisampling is enabled, we use a copy pipeline to copy
the existing contents of our texture to a fresh multisampled frame
buffer (the non-multisampled texture target becomes our resolve buffer).
The Adobe Animate compiler can emit a 'newclass' opcode for
a concrete class before the 'newclass' opcodes for the interfaces
it implements. As a result, we cannot rely on looking up an interface
`ClassObject` when resolving a class's interfaces.
We now store a map of exported classes in `Domain`, and use this
to lookup interfaces before their `ClassObject`s have been created.
Additionally, `link_interfaces` was failing to consider superinterfaces,
which meant that methods from superinterfaces were not being copied
into the vtable. I've fixed this along with the other changes.

The mouse picking behavior in AVM2 interacts in complicated
ways with `mouseEnabled` and `mouseChildren.` It's sufficiently
different from AVM1 that I decided to split the logic into separate
`mouse_pick_avm1` and `mouse_pick_avm2` methods.
The `mouseChildren` property is now fully implemented.
Additionally, the `click_block` tests now work correctly
under Ruffle.
Combined with the orphan-movie PR, this is enough to make
SteamBirds fully playable (though performance greatly degrades
over a course of a level).
These getters were previously calling `local_to_global`
with the unused localX/localY coordinate set to 0. Howver,
`local_to_global` does a matrix multiplication, which in general
will depend on both the x and y values. This was causing the getters
to return incorrect results when any of the `transform.matrix` values
included a non-diagonal matrix.
We now call `local_to_transform` with the real `localX` and `localY`
values.
This is needed by the Newgrounds API. We don't have the ability
to make fake requests to HTTP urls in our test frameworks,
so I haven't added any tests for this. However, I tested locally
that this allows the Newgrounds API to work (and got a medal
in Cloud Wars).
When removing a clip, first check if it has an unload event listener somewhere
it's hierarchy.
If it does, enqueue the removal to happen on the next frame, by moving it to a negative depth.
Previously, we would strip trailing newlines from the contents
of 'output.txt' files, and skip adding a trailing newline after
the final recorded `trace` call.
To reduce the amount of processing we do of expected/ruffle output,
and to make fpcompare tests easier, I've removed the special handling
of newlines. When recording `trace` calls, we now build up a single
large `String`, with a newline after every `trace` message. When
reading in an 'output.txt' file, we do not strip any newlines.
This required adding trailings newlines to lots of 'output.txt' files,
to match the behavior of Ruffle and Flash (the last 'trace' message
ends with a newline, just like every other 'trace' message).
This is a port of a similar regression test written for AVM1.
AVM1 also has a test for hitTestPoint with shapeFlag=true, but it can't
be ported for now, because the implementation of AVM2 hit testing is not
yet accurate enough for it.

This PR implements core 'stage3D' APIs. We are now able
to render at least two demos from the Context3D docs - a simple
triangle render, and a rotating cube.
Implemented in this PR:
* Stage3D access and Context3D creation
* IndexBuffer3D and VertexBuffer3D creation, uploading, and usage
* Program3D uploading and usage (via `naga-agal`)
* Context3D: configureBackBuffer, clear, drawTriangles, and present
Not yet implemented:
* Any 'dispose()' methods
* Depth and stencil buffers
* Context3D texture apis
* Scissor rectangle
General implementation strategy:
A new `Object` variant is added for each of the Stage3D objects
(VertexBuffer3D, Program3D, etc). This stores a handle to the
parent `Context3D`, and (depending on the object) a handle
to the underlying native resource, via `Rc<dyn
SomeRenderBackendTrait>`).
Calling methods on Context3D does not usually result in an immediate
call to a `wgpu` method. Instead, we queue up commands in our
`Context3D` instance, and execute them all on a call to `present`.
This avoids some nasty wgpu lifetime issues, and is very similar
to the approah we use for normal rendering.
The actual rendering happens on a `Texture`, with dimensions
determined by `createBackBuffer`. During 'Stage' rendering,
we render all of these Stage3D textures *behind* the normal
stage (but in front of the overall stage background color).
This is linked to the legacy DisplayObject::Text, which can
only be created by Flash CS6 (but is allowed in AVM2 swfs).
The 'StaticText' class cannot be constructed from ActionScript.
To support this, I've added support for native initializers to
playerglobal. This allows us to throw an exception in the
ActionScript constructor in Test.as, and do nothing in the native
intiializer (so that we can construct it from a DisplayObject).
I've left StaticText.text unimplemented for now, since it will require
dealing with Glyphs
