Change `set_matrix` and `set_color_transform` to accept owned structs,
instead of references. This allows callers that already have an owned
struct to pass it directly, thus saving an unnecessary borrow + clone.
This also aligns with other methods, such as `set_sound_transform`,
which currently accepts an owned struct.
The existing `Object` enum representation is problematic for inherited
native objects, since "regular" `ScriptObject`s cannot be turned into
native objects, but rather a completely new native object needs to be
created. `TObject::create_bare_object` is an attempt to aid this
situation, but it works only for `ActionExtends` inheritance, and not
when the user manually wires up `prototype`/`__proto__` (#701).
In Flash, it seems like derived constructors initially have a "regular"
`this` object. But once the `super()` constructor is invoked, the same
`this` object becomes a native object.
To allow this in Ruffle, introduce a new `NativeObject` enum, and
store it as a member in `ScriptObject`. For a start, move `TextFormatObject`
from the `Object` enum to `NativeObject`. The plan is to gradually
move all `Object` enum variants to `NativeObject`, except for `ScriptObject`.
For now, I've left 'dropTarget' unimplemented - unlike in
AVM1, the drop target can be non-interactive objects like `Shape`,
so we'll need additional refactoring to implement it.
This allows 'This is the only level too' to be playable
It was only used to make structs `#[derive(gc_arena::Collect)]`, and
generally it doesn't make much sense that `render` needs to be GC-aware.
So instead annotate `render` fields in `core` with `#[collect(require_static)]`.
This brings us closer to matching the Flash Player
enumeration behavior. Unfortunately, the precise enumeration
order for ScriptObject properties depends on the precise
order in the internal avmplus hashmap. This order is deterministic,
but adding/removing a property effectively randomizes it. Hopefully
there aren't any SWFS that depend on the *exact* order.
Handle removed clips inline in `Avm1::run_frame`, such that
`DisplayObject::prev_avm1_clip` is no longer used. Thus it can be
removed in a follow-up commit.
When we run a 'goto' where the initial and target frame are the same,
we need to skip triggering any sounds in the target frame.
Some games like 'This is the only level too' rely on this behavior:
they repeatedly run 'movieClip.gotoAndStop(current_frame_id)',
where 'current_frame_id' is the id of a frame that starts playing
a sound. Without this change, the sound will restart every frame
intead of playing exactly once.
We previously used 'coerce_to_object', which produced
an error with `Value::Null`. Instead, we can just ues
`value.as_type_of`, which will correctly handle `null`
The 'charCode' and 'keyCode' properties are now implemented
on `KeyboardEvent`
The input injection code we use does not support keyboard events,
so we can't yet write a regression test for this. However,
both 'You need to burn the rope' and 'This is the Only Level TOO'
now properly handle keyboard events with this PR.
