The current 'setInterval/setTimeout' implementation is
moved to 'core/src/timers.rs', and now works with both
AVM1 and AVM2 objects. The `flash.utils.Timer` class is implemented
mostly in ActionScript, with minimal modifications to the actual
Ruffle timer code.
The `render_list` for a container always contains all of the children
under both AVM1 and AVM2 - howver, the depth_list may not contain
some children under AVM2.
When we're not performing some AVM1-specific operation
(e.g. `getInstanceAtDepth`, or dumping out AVM1 variables),
we should be using the render list.
Remove the `swf_version` parameter from `Activation` constructors,
because this was incorrectly using the global or root SWF version
most times.
Instead, grab the SWF version for the activation directly from the
base clip.
Remove the preload step that would pre-create the shapes for each
morph shape ratio on SWF load. Instead, lazily crate the shapes
when they are needed.
`core` already depends on the `instant` crate which abstracts
`std::instant::Instant` and polyfills it on Web. Use it to replace
`NavigatorBackend::time_since_launch` in order to make `NavigatorBackend`
a little smaller and more simple.
Previously there were 3 implementations of `LocaleBackend`:
`DesktopLocaleBackend`, `WebLocaleBackend` and `NullLocaleBackend`.
While `DesktopLocaleBackend`, `WebLocaleBackend` were identical,
`NullLocaleBackend` always returned a fixed date/time for tests
determinism.
Unify them in a single file, and use `cfg!(test)` and a new dedicated
`deterministic` feature to decide whether to mock date/time or not.
This should not cause any behavioral changes.
Instead of storing shared pointers to `Avm1ConstructorRegistry` in
`MovieLibrary`, access the `PropertyMap` directly, without an extra
abstraction.
Also, move the constructor registries to `Avm1`, for better
encapsulation.
This requires adding another notion of mouse-release events to `ClipEvent`. We now have four:
* `MouseUp` - the mouse was released, any object on the render list can handle this event ("anycast" event)
* `MouseUpInside` - the mouse was released inside this display object, only the mouse-picked target of the event can handle it
* `Release` - the mouse was released inside the last clicked display object
* `ReleaseOutside` - the mouse was released outside the last clicked display object
For those keeping score at home, in AVM2, the valid progression of events is either...
* On the same object, `mouseDown`, `mouseUp`, and `click`
* On one object, `mouseDown`, then some mouse movement that takes the cursor out of the first object, then on another object `mouseUp`, and then finally the first object gets `releaseOutside`.
`onLoadInit` is queued after all `DoAction`s of the loaded clips.
That is, if clip1, clip2, clip3 are loaded in the same frame
(in this order), then actions will be executed as follows:
* `DoAction` of clip3
* `DoAction` of clip2
* `DoAction` of clip1
* `onLoadInit` of clip3
* `onLoadInit` of clip2
* `onLoadInit` of clip1
Previously, those were incorrectly executed as follows:
* `DoAction` of clip3
* `onLoadInit` of clip3
* `DoAction` of clip2
* `onLoadInit` of clip2
* `DoAction` of clip1
* `onLoadInit` of clip1
`handle_clip_event` is now a default trait method that calls three methods in order:
* `filter_clip_event`, to determine which events that either this object or it's children may handle
* `propagate_to_children`, to check if any children of this object want to handle an event. (This also includes AVM2 button states, which are not technically "children" in the usual sense...)
* `event_dispatch`, which does the actual "object reacts to an event" bit if no child handles the object.
These roughly correspond to phases of existing event-handling objects pre-`InteractiveObject`.
Use prototype depths instead. Most calls passed `base_proto = None`,
which is equivalent to `depth = 0`, and is now the default.
The few other cases were adapted to use `Executable::exec` directly,
where `depth` can be specified manually.
The last usage of it was in `Player`, which anyway should operate
only on newly created objects that don't have any virtual properties
nor watchers. So it is safe to replace with `define_value`, that
also cannot fail.
`__proto__` seems to behave much like a regular data property. So
simply remove the `prototype` field of `ScriptObject` in favor of
storing the prototype in the general properties hash map.
This also incurred a large number of ancillary changes, as it turns out nearly every native object is currently pulling a prototype and sticking it into an object. Right now, I have it instead pulling the constructor out of the prototype, but a future PR will also remove `system_prototypes` as well.
Other ancillary changes include:
* `Domain` now supports partial initialization to avoid an order-of-events issue. Accessing domain memory on a partially-initialized `Domain` will panic.
* `Domain` construction requires a full `activation` now, except for `global_scope` which needs to be initialized later with valid domain memory before user code runs.
* Pretty much every native object constructor now takes a proto/constr pair
* Trait lookup was rewritten to handle this. It's still buggy - seven tests don't work
* `TObject.construct` now actually does the full object construction dance. This allows `ClassObject` to implement the ES4 object construction pathway directly while `FunctionObject` maintains ES3 compatibility.
This is a tentative commit; there are still seven failing tests that I need to fix.
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.
Add `RufflePlayer.metadata` that exposes the SWF header fields to
JavaScript.
Add `RufflePlayer.readyState` and fire a `loadedmetadata` event
once the metadata is available, mimicking the HTML5 media APIs.
This appears to only be in use for AVM2. Objects placed on a given frame are constructed before anything else happens with it's parent - even it's constructor being called. This involves splitting AVM2 up into a bunch of steps that really don't make sense for AVM1 content. Hence, `construct_frame` is a no-op for AVM1 and pre-running the first frame when instantiated is AVM1 exclusive now.
* #[derive(Collect)] should be before #[collect]
* Replace redunant `&buf[..]` with `buf`
* Changes most cases of UPPERCase to UpperCase
* Allow upper_case_acronym on most SWF types, as they are from
SWF spec/more annoying to change.
Add an AudioManager struct to handle this list of actively playing
sounds. This will maintain information for each sound instance,
such as the owning display object, AVM1 object, etc.
This will allow us to implement the awkward AVM1 Sound API in a
fairly backend-agnostic way.
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.
Add `backgroundColor` setting to the config options, allowing
a user to override the background color of an SWF. The polyfill
will now look for the `bgcolor` HTML attribute on the embed
and fill in this setting appropriately.
Player::background_color is now an Option. SetBackgroundColor will
change the background color of the player only when this is None,
i.e. only if no background color has yet been set.
This matches the behavior of the offical Flash Player, for example,
if a parent SWF is missing a SetBackgroundColor tag and loads a
child SWF, the child SWF's SetBackgroundColor tag takes effect.
This is anticipating adding a `bgcolor` option to the web builds,
allowing the HTML embed to override the bgcolor.
Player::set_letterbox can be used to control the letterbox behavior.
* Letterbox::Off => no letterbox (flash behavior)
* Letterbox::Fullscreen => letterbox only in fullscreen (web default)
* Letterbox::On => always letterbox (desktop default)
Add --timedemo for benchmarking, which will run the given SWF as
quickly as possible for 5000 frames or the end of the root
timeline, whichever comes first. The total duration will be output
upon completion.
The purpose of this refactor is twofold:
1. Ensure `TDisplayObjectContainer` holds all the container methods we need
2. Ensure that future adjustments to trait methods automatically apply to the display object's own use of the container, in case we want to do things in those methods that can't be done in a borrowed container
There are two places where we cannot use the new trait methods:
1. `Button.set_state` as it holds a borrow at the point we want to clear the container
2. `MovieClipData.goto_remove_object`, since it's a method on the data and thus cannot access trait methods
This particular commit generates a lot of noise as several `DisplayObject` methods were incorrectly marked as non-mutating.
This event fires for new clips before any construct clip events.
Split the action queue up into separate priorities, giving
initialize the highest priority.
If a masker is placed inside a masker, the inner mask is inactive
and instead renders as normal art, masked by the outer mask. Properly
handle this case by only pushing new masks if we are not currently
drawing the mask stencil.
Maskee inside maskee still functions as expected. (i.e., a clip
using a mask is masked itself).
This is the same way that AVM1 actions run and it appears that frame scripts work exactly the same way. It fixes all outstanding bugs with movie clip navigation in AVM2 and allows me to remove a lot of weird workarounds I was writing for the old, incorrect behavior.
I'm also removing the "last run script frame" rule as `run_frame_internal` already had rules to prevent stopped clips from rerunning actions.
