Don't call `render` from `Player::tick`; instead, require the
frontends to explicitly call `render` when they wish to redraw.
The frontend can query `Player::needs_render` to see if the stage
is dirty and needs a redraw. Update desktop and web to use this
new method.
This fits better with the newer winit event loop model, which
requires explicitly calling `request_redraw`, and should avoid
spurious renders.
A previous version of this PR (whose history has been scrubbed, but go check 918d88abe68b7467a4194738b95e5bf3e9b5bb72 if you're curious) implemented a new `TObject` property which basically every line of code that dealt with object construction had to populate. It was terrible.
This is accomplished via two new `TObject` methods: `has_own_virtual` and `call_setter`. If an object does not contain it's own version of a property, it will first crawl the prototype chain to see if there is an overwritable virtual. If so, it will invoke that prototype's setter.
A bit of borrow finangling was required to do this; `super` now no longer caches it's proto and constr values and instead dynamically constructs them. This also means it can't be downcasted to `Executable` anymore.
With this commit, virtual setters and super-setters now work correctly.
A base prototype is only applicable in cases where a method is being called as a property on an object. Bare function calls, `apply`/`call` calls, and so on do not generate a base prototype.
We also add a convenience method, `call_method`, to all objects. This method automatically calculates the correct base prototype for a method call on an object, which is the only operation that should generate base prototypes.
Revert to the old action queue method of popping off actions in a
loop, as new actions can be queued while iterating. Store proto
changes in a separate queue to maintain the high priority behavior.
Change `ActionGetTime` (`getTimer`) to use a new backend method.
This allows it to return updated times if it is called multiple
times in a single frame. This fixes hangs caused by games that use
busy-loop "frame limiter" code.
`PropertyMap` wraps over `IndexMap` to handle object properties in
AVM1. All insert/remove/get methods require and `swf_version`
parameter, and the `PropertyMap` will take care of handling case
senstivity and maintaing iteration order based on the SWF version.
First implementation of Button object. Hook up to the button
display object and run onRelease etc. methods as appropriate.
Pull out common display object methods into globals::display_object.
This conversion allows negative octal values, but not negative
hex values, and ignores only leading ASCII whitespace. A test
for this behavior is included.
Specifically fall back to the device font when the UseOutlines
flag is not set in DefineEditText (SWF19 p.172). Fixes#451.
Note that since we only use a single font for "device" rendering,
this may sometimes be a different font than is specified in the
Flash IDE.
It doesn't feel like Flash without having the hand cursor display
when hovering over buttons. First pass at implementing this;
core communicates which mouse cursor to use via
`InputBackend::set_mouse_cursor`.
TODO: Hand cursor only displayed for Button display objects
currently. Movie clips should also display this when they are in
"button mode" (when a button mouse event is set on them in AVM1,
or `buttonMode` property in AVM2).
Implements MovieClip.getBounds, and also reorganized the
DisplayObject AABB methods:
* `self_bounds` calculates the inherent untransfomed bounds of
the object without children. All `DisplayObject`s must implement
this method. For example, `Bitmap` returns the size of bitmap.
Composite objects like `MovieClip` return a null AABB because they
are made up of only children.
* `bounds` calculates the untransformed bounds including children.
* `local_bounds` calculates the bounds relative to the object's
parent.
* `world_bounds` calculates the bounds in global stage space.
* `bounds_with_transform` calculates a tight AABB for the object
with a given transform, and is used to implement the above.
Try to keep style more consistent by using functions for all MC
methods. Previous was a mix of closures and functions (we're still
a little bad with this elsewhere)
This is caused by the fact that `avm.root_object` references the *current* stack frame, not the one we are about to introduce. Ergo, we need to pull the base clip of the *new* stack frame and find it's root.
This particular behavior only crops up in situations where there can be multiple root objects, at least until we implement `_lockroot`.
`_root` is calculated dynamically based on the clip the currently executing function was called in.
Other things that used `context.root` have been changed to either update all layers or just update layer 0, which is the former `context.root`.
Interestingly enough, very little actually has to be done inside the async process for XML. The async process basically just fetches data and fires an event handler when it's done. Everything else is handled via a system builtin, `XML.onData`.
This implementation just returns the size of the current loaded movie. The test is also deliberately written to be loose on timings so that it likely won't see a partially loaded movie. (I don't want it to be a test of load events, so I just wait a few frames, rather than the correct way of waiting for `onLoadComplete`.)
Until we support streaming file loads, we can't faithfully support these properties. Still, it's better to have them, just in case.
This is technically better, but it may make more sense to trigger `ClipEvent::Load` at the start of the next frame instead. Furthermore, I don't know if other forms of load events should trigger on the next frame (or end of the current one) like this.
This also adjusts `MovieClip.unloadMovie` to do just that, instead of removing the clip from the display list. We also have to unload clips when loading new movies into them, since `unloadMovie` desugars to loading `""` as the URL.
Interestingly, this constitutes an implementation of `AsBroadcaster`. It appears Macromedia decided to implement event handling on `MovieClipLoader` in a very similar fashion to `AsBroadcaster`, down to invoking `broadcastMessage` and searching a `_listeners` property for listeners.
*De*implement the free function versions of the above, as well as their `Num` variants, since they don't actually exist as callables. Instead, the ActionScript compiler treats them as preprocessor functions that represent various forms of `ActionGetURL`/`ActionGetURL2`.
This function is part of `Avm1`, rather than a hypothetical `LayerManager`, because we're going to need to eventually construct layers differently for AVM2.
