This interface handles returning a bitmap given an ID and is used
by the render backend to get the bitmap used for a bitmap fill.
This will allow for bitmap fills in the drawing API, as these will
manage their own list of bitmaps.
This also removes the MovieLibrary dependency from render backends
and will allow for better decoupling in the future.
PR #4540 allowed shapes to replace their inner art handles via
replace PlaceObject tags. This can also happen for morph shapes and
static texts.
Add MorphShape::replace_with and Text::repalce_with. This fixes the
incorrect art in main menu buttons of Super Mario 63.
A `PlaceObjectAction::Replace` signals that a shape should
be swapped with a different shape. Previously we instantiated a
completely new `Graphic`, but this is incorrect; instead the
underlying shape handle should be swapped out, but the outer object
remains. This is visible in AVM2 where you can access `Shape` as
a normal display object.
When reading an SWF, search for FileAttributes and
SetBackgroundColor and return this along with the header data
because it's useful (in particular, the AS3 flag).
Move `MovieClip::is_swf` flag to `DisplayObject::is_root`, and use
this flag to handle the behavior of `DisplayObject.root` crawling
upwards until it hits a top-most loaded SWF/Bitmap.
Simplify `root` and `stage` so that they don't have to consider
buttons. Instead, do some trickery to ensure the button's states
see the proper values of `parent`, `root`, and `stage` during
construction.
Maintain an external mapping from symbol names to registered
constructors to properly handle `registerClass` being called on
not-yet-available symbols.
SWFs v6 and v7+ each have a separate global mapping, with
different case sensitivities.
Also returns the correct boolean value to the AVM.
Fixes#2343 and #1864.
Pass the movie library to `register_shape` methods so that bitmap
charcter IDs can be resolved immediately on the proper SWF.
This fixes#2037, which cause incorrect bitmaps to be used when
multiple movies were loaded.
This uses a "VM tendency" system wherein the presence of `DoAction` or `DoInitAction` tags defaults the movie to AVM1, while the presence of `DoABC` defaults to AVM2. The presence of a `FileAttributes` tag allows setting the VM tendency in the same manner using it's AS3 bit.
Particularly malformed SWFs may cause execution issues if Flash Player uses a dramatically different system from this.
This involves a new struct called a `FontDescriptor` which is generated whenever a font is registered and used to index the font in the library. When a font is requested, it goes through the descriptor system to get found.
Note that host objects that do so will *not* have access to their standard representation from within member functions - you will need to extend the interface to accomodate for them. This is due to long-standing limitations with type IDs and downcasting with types that bear lifetimes - it's entirely an unsafe operation and exposing such a facility to safe Rust is unsound. However, this will at least let us separate out several things from ScriptObject that don't need to be there for the time being.
Converts the Bitmap character to a proper display object. This can
be instantiated directly in a PlaceObject tag in SWFv9 movies,
compared to the previous versions which indirectly references
bitmaps from Shape tags.
