If a child named 'foo' is removed by the timeline (without
having been previous added/removed from the timeline by ActionScript),
then the 'foo' field in the parent will be set to null. This occurs
even if the 'foo' field in the parent is not currently set to
the child 'foo' (e.g. 'this.foo = someOtherObject' was executed by
ActionScript).
- we can now get a `&RawTable` from a `&HashSet`, meaning we can store a
`HashSet` directly in the interner;
- `RawTable::iter_hash` now allows the removal of already-yielded
elements during iteration, which simplifies `WeakSet::entry`
Previously `last_mouse_position` was updated irrespectively of
whether the dragged object was inside or outside the constraint
box. Change it follow mouse deltas, after clamping is performed.
Fixes#11254.
When we run a 'goto', a weird "nested frame" gets triggered.
Previously, we were only calling `construct_frame` on the target
MovieClip as part of this "nested frame". However, Flash Player
seems to treat this (in some ways) like a normal frame - *all*
objects on the Stage (and orphans) have `construct_frame` called.
In particular, `gotoAndStop`/`gotoAndPlay` is called during
an "enterFrame" event handler, then unrelated objects on the Stage
will have their children constructed during the execution of
`gotoAndStop`/`gotoAndPlay`. The same logic holds for frame scripts.
This fixes a bug in Steamlands, which relies on children on the main
timeline being constructed immediately following a call to `gotoAndStop`
on an orphan (originally triggered from an "enterFrame" handler).
When we iterate over the orphan list to run frame lifecyle methods,
the orphan list may be modified (e.g. an event listener creates a new
orphan object). To ensure that we iterate over all of the orphans
originally present, this commit wraps the orphan list in an `Rc`
(just like we do for the render list). Modifications to the list use
`Rc::make_mut`, and iteration operates on a clone of the `Rc`.
QName can contain characters like '.' and '<' as part of the
package or class name (though this requires editing the SWF
or using a nonstandard compiler). This broke our attempt to parse
generic type paramters by looking for '.<'
Instead, our 'Vector' special casing now operates on the unparsed
'AVMString' name, instead of attempting to construct a 'QName'.
This means that we don't need to handle generic paramters at
all for obfuscated names (which will never start with '__AS3__'
or 'Vector.<')
This fixes a bug in Red Ball 4v3, which has an obfuscated class
'!D.<H'
If we have two PlaceObject tags in the same frame with the same depth,
only the first one actually places an object. The second one is ignored
(Flash Player logs a warning).
There are only a few places where we actually need to use the
`caller_domain`, so we don't actually need it available for most native
method calls. This means that `Activation::from_nothing` can be used
in the vast majority of cases without causing a panic later on.
We now parse PixelBender bytecode, and populate the parameters
from the bytecode on `ShaderData`. This is enough to progress
Steamlands, which needs to access dynamically set properties
on `ShaderData`
Bytecode execution is not implemented yet.
When we create a DisplayObject from ActionScript, we should always
run `construct_frame` on it, regardless of what frame phase we
are currently in.
This fixes a regression in Fancy Pants World 4 Part 1, where entering
the first door produced an error.
Flash Player performs `x + width` and `y + height` as floating
point operations before `round_to_even`. This affects the extent
covered by a `Rectangle` in various BitmapData methods, as the sum
of two values might be large enough to be rounded up to a larger
value (when rounding `x` and `width` individually would have
produced a smaller overall extent).
These are directly set on the underlying navigator's HTTP
request type, and get printed out in our test navigator backend.
No validation of the header names is performed - on web, this will be
enforced by the browser.
When we iterate over a render list (in order to call
`enter_frame`, `construct_frame, etc.) we need to be sure
that we iterate over all of the original `DisplayObjects`
in the list, even if the list is modified during iteration
(e.g. some ActionScript code calls `parent.addChildAt`).
Previously, `RenderIter` would repeatedly call `child_by_index`
on the original `DisplayObjectContainer`, up to the original
child count. If new DisplayObjects were inserted into the list
during iteration, we could miss some of the original DisplayObjects
in the list (as they are now at a greater position in the list).
To solve this, we now store the render list as an `Rc<Vec>`,
and use `Rc::make_mut` to modify it. See the comments
for more details.
With SWF version < 30, Context3D.configureBackBuffer throws
an error with a less informative message when the width/height
are out of range. Additionally, it seems to special case
the case width=0, height=0, antiAlias=0. enableDepthAndStencil=false,
and does *not* throw an error. This is relied on by Sniper Team.
The Flash Player 'Matrix3D.recompose' method throws exceptions under
certain circumstances with the "quaternion" orientation style.
I haven't yet figured this out yet, so I've marked that case as a stub.
All of the implementations are based on the OpenFL code, with some
tweaks to match Flash Player's behavior.
TextFields have a very unusual behavior - if they are selectable
and have `was_static`, they *block* the dispatch of mouse events when
they're targeted (not even the Stage will receive the event).
This only occurs when the TextField is actually targeted
(which requires mouseEnabled=true). With mouseEnabled=false,
the event will be dispatched with an ancestor as the target,
following the usual logic.
Also, TextFields now properly propagate mouse picks to
their parent if mouseEnabled=false. Previously, setting
mouseEnabled=false for a TextField made all mouse picks
cause a miss on it. This was the cause of the Turbo Kids
regression.
Fixes#10245
This can actually affect runtime behavior - if the return type is
declared as 'int', then an instance of a custom class will get
coerced to 0 when returned by the function.
'Plants vs Zombies Demo' relies on this - it has a function which
incorrectly returns an object instead of an array index, but the
value gets silently coerced to 0 under Flash Player.
