PouleyKetchoupp c0b394572f Fix Return key events in LineEdit & TextEdit on Android
Depending on the device implementation, editor actions could be
received with different action ids or not at all for multi-line.

Added a parameter to virtual keyboards to properly handle single-line
and multi-line cases in all situations.

Single-line:
Input type set to text without multiline to make sure actions are sent.
IME options are set to DONE action to force action id consistency.

Multi-line:
Input type set to text and multiline to make sure enter triggers new lines.
Actions are disabled by the multiline flag, so '\n' characters are
handled in text changed callbacks.

Rémi Verschelde 7bf9787921 SCons: Format buildsystem files with psf/black
Configured for a max line length of 120 characters.

psf/black is very opinionated and purposely doesn't leave much room for
configuration. The output is mostly OK so that should be fine for us,
but some things worth noting:

- Manually wrapped strings will be reflowed, so by using a line length
  of 120 for the sake of preserving readability for our long command
  calls, it also means that some manually wrapped strings are back on
  the same line and should be manually merged again.

- Code generators using string concatenation extensively look awful,
  since black puts each operand on a single line. We need to refactor
  these generators to use more pythonic string formatting, for which
  many options are available (`%`, `format` or f-strings).

- CI checks and a pre-commit hook will be added to ensure that future
  buildsystem changes are well-formatted.

[Windows, 3.2] Add tablet driver selection. 2020-05-20 09:36:56 +03:00
Hugo Locurcio 6fb6107e6a Warn when trying to open `res://` or `user://` with `OS.shell_open()`
`OS.shell_open()` will pass on the path directly to the OS' shell
handler (which can handle file paths or URLs). It can't handle
Godot-specific paths, so these need to be converted with
`ProjectSettings.globalize_path()` first.

Happy new year to the wonderful Godot community!

We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
pipeline from hundreds of contributors.

Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.

lawnjelly bf6c301b9c Add access to interpolation fraction for fixed timestep interpolation
Addresses #30068

This is a prerequisite for allowing proper support for fixed timestep interpolation, exposing the interpolation fraction to the engine, modules and gdscript.

The interpolation fraction is the fraction through the current physics tick at the time of the current frame.

Fabio Alessandrelli 564d93ff10 CryptoCore class to access to base crypto utils.
Godot core needs MD5/SHA256/AES/Base64 which used to be provided by
separate libraries.
Since we bundle mbedtls in most cases, and we can easily only include
the needed sources if we so desire, let's use it.

To simplify library changes in the future, and better isolate header
dependencies all functions have been wrapped around inside a class in
`core/math/crypto_base.h`.

If the mbedtls module is disabled, we only bundle the needed source
files independently of the `builtin_mbedtls` option.
If the module is enabled, the `builtin_mbedtls` option works as usual.

Also remove some unused headers from StreamPeerMbedTLS which were
causing build issues.

Andrii Doroshenko (Xrayez) 883ef8570a Expose 2D polygon boolean operations in Geometry singleton
Clipper 6.4.2 is used internally to perform polypaths clipping, as well
as inflating/deflating polypaths. The following methods were added:

```
Geometry.merge_polygons_2d(poly_a, poly_b) # union
Geometry.clip_polygons_2d(poly_a, poly_b) # difference
Geometry.intersect_polygons_2d(poly_a, poly_b) # intersection
Geometry.exclude_polygons_2d(poly_a, poly_b) # xor

Geometry.clip_polyline_with_polygon_2d(poly_a, poly_b)
Geometry.intersect_polyline_with_polygon_2d(poly_a, poly_b)

Geometry.offset_polygon_2d(polygon, delta) # inflate/deflate
Geometry.offset_polyline_2d(polyline, delta) # returns polygons

// This one helps to implement CSG-like behaviour:
Geometry.transform_points_2d(points, transform)
```

All the methods return an array of polygons/polylines. The resulting
polygons could possibly be holes which could be checked with
`Geometry.is_polygon_clockwise()` which was exposed to scripting as well.

Luis Martinez 9e465c9fd0 Fixes stderr silence; adds missing quote from exe args(windows)
8d117b214f/core/bind/core_bind.cpp (L452)
This function calls the bottom function

8d117b214f/drivers/unix/os_unix.cpp (L312)

OS.execute doesn't send out a value to stderr, so stderr defaults to
false, which will invoke this bottom line and always silence stderr.

8d117b214f/drivers/unix/os_unix.cpp (L315)

Some programs, such as FFmpeg, will print out to stderr with valuable
and vital information. This fixes stderr always being silenced, user can
now opt to have it be read as normal.

Ruslan Mustakov 1d9a3a9b1c iPhone X support and iOS-related fixes
Starting from April 2018 Apple no longer accepts apps that do not
support iPhone X. For games this mainly means respecting the safe area,
unobstructed by notch and virtual home button. UI controls must be
placed within the safe area so that users can interact with them.

This commit:

- Adds OS::get_window_safe_area method that returns unobscured area of
  the window, where interactive controls should be rendered.

- Reorganizes how launch screens are exported - the previous way was
  incorrect and modern iPhones did not pick up the correct screens and
  because of that used a non-native resolution to render the game.

- Adds launch screen options for iPhone X.

- Makes launch screens optional in the export template. If not
  specified, a white screen will be used.

- Adds App Store icon (1024x1024) export option as it now has to be
  bundled with the app instead of being provided in iTunes Connect.

- Fixes crash when launching games in iOS Simulator. It happened because
  controllerWasConnected callback came before the engine was
  initialized. Now in such case the controllers will be queued up and
  registered after initialization is done.

- Fixes issue with the virtual keyboard where for some reason
  autocorrection panel would intersect with the keyboard itself and not
  allow you to use the top row of the keyboard. This is fixed by
  disabling autocorrection altogether.

Closes #17358. Fixes #17428. Fixes #17331.

Manuel Moos d5abd4eb75 Add hysteresis to physics timestep count per frame
Add new class _TimerSync to manage timestep calculations.
The new class handles the decisions about simulation progression
previously handled by main::iteration(). It is fed the current timer
ticks and determines how many physics updates are to be run and what
the delta argument to the _process() functions should be.

The new class tries to keep the number of physics updates per frame as
constant as possible from frame to frame. Ideally, it would be N steps
every render frame, but even with perfectly regular rendering, the
general case is that N or N+1 steps are required per frame, for some
fixed N. The best guess for N is stored in typical_physics_steps.

When determining the number of steps to take, no restrictions are
imposed between the choice of typical_physics_steps and
typical_physics_steps+1 steps. Should more or less steps than that be
required, the accumulated remaining time (as before, stored in
time_accum) needs to surpass its boundaries by some minimal threshold.
Once surpassed, typical_physics_steps is updated to allow the new step
count for future updates.

Care is taken that the modified calculation of the number of physics
steps is not observable from game code that only checks the delta
parameters to the _process and _physics_process functions; in addition
to modifying the number of steps, the _process argument is modified as
well to stay in expected bounds. Extra care is taken that the accumulated
steps still sum up to roughly the real elapsed time, up to a maximum
tolerated difference.

To allow the hysteresis code to work correctly on higher refresh
monitors, the number of typical physics steps is not only recorded and
kept consistent for single render frames, but for groups of them.
Currently, up to 12 frames are grouped that way.

The engine parameter physics_jitter_fix controls both the maximum
tolerated difference between wall clock time and summed up _process
arguments and the threshold for changing typical_physics_steps. It is
given in units of the real physics frame slice 1/physics_fps. Set
physics_jitter_fix to 0 to disable the effects of the new code here.
It starts to be effective against the random physics jitter at around
0.02 to 0.05. at values greater than 1 it starts having ill effects on
the engine's ability to react sensibly to dropped frames and framerate
changes.
