New configuration options (changing the navigate_to_url call handling)
have been added. The default behaviour has been changed as well.
A NavigateWebsiteHandlingMode enum has been added to Ruffle (in Rust and
Typescript). It contains the values "Allow", "Confirm" and "Deny" and
describes how navigate_to_url website calls should be handled. Allow
means that all website calls are allowed, Confirm means that a
confirmation window opens with each website call and Deny means that all
website calls are denied.
A respective navigate_website_handling_mode variable has been added to
the desktop CLI and to the JS config. The default value is "Confirm" in
each. The variable is given to the navigator (ExternalNavigatorBackend
or WebNavigatorBackend, depending on the platform) and is saved in it.
On each navigate_to_url website call, the respective navigator is now
checking navigate_website_handling_mode and acts correspondingly (allows
it, opens a confirmation window or denies it).
This changes the default behaviour of Ruffle from allowing all website
calls to opening a confirmation window with each website call.
On Safari, the confirm window can cause the background music to stop,
but this seems to be an issue with Safari.
Closes#838.
Additionally, an allow_javascript_calls variable (which defaults to
false) has been added to the desktop CLI. The variable is given to the
desktop navigator and is saved in it.
If a navigate_to_url javascript call is executed on desktop, the
navigator is now checking allow_javascript_calls and acts
correspondingly (allows it or denies it).
This changes the default behaviour of Ruffle on desktop to not allowing
javascript calls.
Closes#9316.
Generally, when transforming a difference between two points, `p1`
and `p2`, with a matrix `m`, we would like the following property
to hold:
```
m * (p1 - p2) == m * p1 - m * p2
```
Unfortunately, it wasn't like this before, because matrices have a
translation component, which is non-linear. In `m * p1 - m * p2`,
the translations of `m * p1` and `m * p2` are the same and therefore
cancel out each other. However, in `m * (p1 - p2)` the translation
stays.
In order to preserve this property, introduce a new `PointDelta`
type which is not subject to translation when transformed by a matrix.
For now, the following operations are supported:
* `Point - Point -> PointDelta`
* `Point + PointDelta -> Point`
* `Point += PointDelta`
* `Point - PointDelta -> Point`
* `Point -= PointDelta`
As a consequence, the expression `position + global_to_local_matrix * mouse_delta`
in `update_drag()` now ignores translation, which fixes#817.
`startDrag()` used to capture the offset between the mouse cursor
and dragged object. This is buggy when the dragged object position
is changed *while* being dragged, as the original offset no longer
holds.
Change the dragging mechanism to be based purely on mouse deltas,
eliminating said offset completely.
Fixes#10775.
The problem seems to have been the inclusion of setting values
that the previous equality function did not handle correctly.
This function broadens the kinds of setting values that can
be handled correctly.
Previously, `AsBroadcaster` was defined as a plain object. However,
it seems like in Flash it is defined as an empty function instead.
This means expressions like `new AsBroadcaster()` should return a
newly-created object. This is in opposition to the documentation
that says there is no constructor function for the `AsBroadcaster`
class.
Fixes#10673.
