The suggested changes to the navigate_to_url handling in the feedback to
the pull request have been implemented.
Therefore, this commit consists of multiple smaller changes:
1. The allow_javascript_calls variable has been removed (as a CLI
argument and in the navigator). Javascript calls are now always denied
on desktop. This is because setting the argument was useless; no
javascript was executed in any case, at most, just a browser tab opened.
Therefore, it makes no sense to include this option.
2. The NavigateWebsiteHandlingMode default value has been provisionally
changed from Confirm to Allow. In the future (after a GUI toolkit has
been added), the default confirmation windows should include a "Save
this preference" checkbox.
3. The NetworkingRestrictionMode enum has been renamed to
NetworkingAccessMode since the previous naming was counter-intuitive.
4. The NavigateWebsiteHandlingMode enum (and variables related to it)
have been renamed to OpenURLMode to simplify the name.
5. The documentation has been improved.
The networking API restrictions imposed by the allowNetworking parameter
& attribute have been added and partially implemented.
A new NetworkingRestrictionMode enum has been added to Ruffle (in Rust
and Typescript). It contains the values "All", "Internal" and "None" and
models the possible values of the allowNetworking parameter / attribute.
All means that all networking APIs are permitted in the SWF file,
Internal means that the SWF file may not call browser navigation or
browser interaction APIs and None means the same and that the SWF file
cannot use any SWF-to-SWF communication APIs either.
A respective allowNetworking variable has been added to the JS config.
Its default value is All.
Ruffle now recognises the allowNetworking parameter and attribute in the
SWF HTML object and parses it and sets the config variable
correspondingly if it's recognised.
Only if the variable is set to All, the external interface (responsible
for javascript calls in AS3) is created. Additionally, the variable is
given to the WebNavigatorBackend and saved in it. The navigator denies
all navigate_to_url calls if the variable hasn't been set to All.
Therefore, the API restrictions imposed by setting allowNetworking to
internal or none have been partially implemented.
Formatting has been improved.
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.
