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.
* Remove ^M characters from Dictionary test
Using Github's automatic line ending conversion to CRLF.
* Remove ^M characters from dictionary_delete test
* Remove ^M characters from dictionary_in test
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.
