Godot supports many different compilers and for production releases we
have to support 3 currently: GCC8, Clang6, and MSVC2017. These compilers
all do slightly different things with -ffast-math and it is causing
issues now. See #24841, #24540, #10758, #10070. And probably other
complaints about physics differences between release and release_debug
builds.
I've done some performance comparisons on Linux x86_64. All tests are
ran 20 times.

I have also looked at FPS numbers for tps-demo, 3d platformer, 2d
platformer, and sponza and could not find any measurable difference.
I believe that given the issues and oft-reported (physics) glitches on
release builds I believe that the couple of percent of tight-loop
floating point performance regression is well worth it.
This fixes#24540 and fixes#24841
By introducing an intermediate proxy class for the array subscript
operator for String and CharString we can control better when CowData
will actually CoW.
This should improve performance of String usage for most cases.
Contrarily to what #23434 assumed, this is not a memory leak,
the VisualServerRaster instance is passed as a parameter to
VisualServerWrapMT's constructor.
Fixes#23437.
Also turn off -Wsign-compare warnings in the future, we do not consider them important.

This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.
Previously the compiler would use system headers located at
/System/Library/Frameworks, which could result in compilation failures
due to the headers not always being up-to-date in regards to the
latest installed macOS SDK headers that come with Xcode.
Fix the issue by passing the SDK path via the -isysroot option to the
compiler and linker invocations.
If no custom SDK path is given, the build system queries the SDK path
via xcrun --show-sdk-path, which returns something similar to
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/
/Developer/SDKs/MacOSX.sdk/
Querying via xcrun is now also done for iphone (and simulator)
platforms as well.
Here is an example of a compilation failure message due to outdated
headers:
platform/osx/os_osx.mm:1421:41: error: use of undeclared identifier 'NSAppKitVersionNumber10_12'; did you mean 'NSAppKitVersionNumber'?
if (floor(NSAppKitVersionNumber) >= NSAppKitVersionNumber10_12) {
^~~~~~~~~~~~~~~~~~~~~~~~~~
NSAppKitVersionNumber
/System/Library/Frameworks/AppKit.framework/Headers/NSApplication.h:26:28: note: 'NSAppKitVersionNumber' declared here
This adds a static is_viable() method to all rasterizers which has to be
called before initializing the rasterizer. This allows us to check what
rasterizer to use in OS::initialize together with the GL context
initialization.
This commit also adds a new project setting
"rendering/quality/driver/driver_fallback" which allows the creator of a
project to specify whether or not fallback to GLES2 is allowed. This
setting is ignored for the editor so the editor will always open even if
the project itself cannot run. This will hopefully reduce confusion for
users downloading projects from the internet.
We also no longer crash when GLES3 is not functioning on a platform.
This fixes#15324
This commit makes operator[] on Vector const and adds a write proxy to it. From
now on writes to Vectors need to happen through the .write proxy. So for
instance:
Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;
Failing to use the .write proxy will cause a compilation error.
In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.
_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.
-Project/Editor settings now show tooltips properly
-Settings thar require restart now will show a restart warning
-Video driver is now visible all the time, can be changed easily
-Added function to request current video driver
PR #18675 (commit 96301e9) revealed a problem with how iOS lifecycle
callbacks were handled by Godot. Before that PR it was possible to get
NOTIFICATION_WM_FOCUS_IN callback without getting the corresponding
NOTIFICATION_WM_FOCUS_OUT. That commit added a flag to ensure they are
always coupled, but now there is an issue when, for example, you open a
notification panel on iOS without moving the app to background.
It resulted in view.stopAnimation being called without the
corresponding startAnimation when the app moves to foreground again, so
it looked like the game hanged.
I changed focus out notification to be sent in applicationWillResignActive,
because it makes more sense than to do it in applicationDidEnterBackground,
because it is always called in pair with applicationDidBecomeActive, where
focus in is sent. applicationDidEnterBackground may not come under
circumstances that are now described as a comment in code.
When a phone call or an alarm triggers on iOS, the application receives
an "audio interruption" and it's up to the application to resume
playback when the interruption ends. I added handling for audio
interruptions same as if the game is focused out and then back in.
Now generating mouse events from touch is optional (on by default) and it's performed by `InputDefault` instead of having each OS abstraction doing it. (*)
The translation algorithm waits for a touch index to be pressed and tracks it translating its events to mouse events until it is raised, while ignoring other pointers.
Furthermore, to avoid an stuck "touch mouse", since not all platforms may report touches raised when the window is unfocused, it checks if touches are still down by the time it's focused again and if so it resets the state of the emulated mouse.
*: In the case of Windows, since it already provides touch-to-mouse translation by itself, "echo" mouse events are filtered out to have it working like the rest.
On X11 a little hack has been needed to avoid a case of a spurious mouse motion event that is generated during touch interaction.
Plus: Improve/fix tracking of current mouse position.
** Summary of changes to settings: **
- `display/window/handheld/emulate_touchscreen` becomes `input/pointing_devices/emulate_touch_from_mouse`
- New setting: `input/pointing_devices/emulate_mouse_from_touch`
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.
Using `misc/scripts/fix_headers.py` on all Godot files.
Some missing header guards were added, and the header inclusion order
was fixed in the Bullet module.
- EditorExportPlugin's _export_begin accepts all the arguments related
to the current export (is_debug, path, flags).
- EditorExportPlugin API is extended with methods allowing to configure
iOS export: add_ios_framework, add_ios_plist_content,
add_ios_linker_flags, add_ios_bundle_file.
- iOS export template now contains Godot as a static library so that
it can be linked with third-party Frameworks and GDNative static
libraries.
- Adds method to DirAccess for recursive copying of a directory.
- Fixes iOS export to work with Xcode 9 (released recently).
There are still some left in the Android Java code, even stuff to swap between
GLES1 and GLES2 support from early Godot days... would be good to see some cleanup
there too one day.
The "graphics/api" option for Android exports is removed, as only GLES 3.0 is supported.
It can be readded when GLES 2.0 support comes back. Fixes#13004.
It had been missed in d09160a8b6 and broke compilation
for those platforms.
Took the opportunity to run clang-format on the code base to fix some corner cases
that went through our static tests/were overlooked recently.
These changes allow to open the exported project in XCode and Run it
immediately to begin debugging. Before these changes you'd have to
sign GDNative libs and change Build Configuration manually.
Now that #12009 is merged, we should let the system find the binary on
the users $PATH and don't assume we know where to look for them in
different distributions.
On mobile platforms virtual keyboards take up significant amount of
screen space and UI containing a text box may need to be adjusted
after the keyboard appears to keep the text box visible to user. This
commit adds a way to obtain virtual keyabord height so that controls
are aware of how much they need to move.
- The export process now builds complete .ipa on macOS, instead of just
creating XCode project.
- The project includes Capabilities games usually require: Game Center,
Push Notifications, In-App Purchase.
- Icons and launch screens can be specified in export preset.
Previously logging logic was scattered over OS class implementations
with plenty of duplication. Major changes in this commit:
- Extracted logging logic into a separate Logger hierarchy. It allows
easy configuration of logging mechanism depending on compile-time or
run-time configuration.
- Implemented RotatedFileLogger which is usually used with StdLogger,
providing persistency of logs. It is often important to be able to
obtain logs of the game even in production to be able to understand
what happened prior to some problem. On mobile there previously was
no way to obtain the logs aside from having the device connected to
your machine.
- flush() is not performed in release mode for every logged line. It
is only performed for errors.
- The Windows, UWP, Android (on Windows) and Linux builds are
tested with Scons 3.0 alpha using Python 3.
- OSX and iOS should hopefully work but are not tested since
I don't have a Mac.
- Builds using SCons 2.5 and Python 2 should not be impacted.
- Fixes some single-dash leftovers that were missed in the previous commit
- Reorder the help output for clarity, and document missing options
- Drop obsolete options: --noop, --pack, --editor-scene, --level, --import, --import-script, --no-quit
- Improve error message on malformed arguments and do not display help on error
- Always use long form of arguments when starting a new Godot process from C++, for clarity and easy grepping
- Cleanup obsolete code here and there
- Fixes some single-dash leftovers that were missed in the previous commit
- Reorder the help output for clarity, and document missing options
- Drop obsolete options: --noop, --pack, --editor-scene, --level, --import, --import-script, --no-quit
- Improve error message on malformed arguments and do not display help on error
- Cleanup obsolete code here and there
Tried to organize the configure(env) calls in sections, using the same order
for all platforms whenever possible.
Apart from cosmetic changes, the following issues were fixed:
- Android: cleanup linkage, remove GLESv1_CM and GLESv2
- iPhone: Remove obsolete "ios_gles22_override" option
- OSX:
* Fix bits detection (default to 64) and remove obsolete "force_64_bits" option
(closes#9449)
* Make "fat" bits argument explicit
- Server: sync with X11
- Windows: clean up old DirectX 9 stuff
- X11:
* Do not require system OpenSSL for building (closes#9443)
* Fix typo'ed use_leak_sanitizer option
* Fix .llvm suffix overriding custom extra_suffix
- nicely exit if initialisation fails
- fix a few issues around new event handling
- use 16bit single channel framebuffer as 32bit is not supported on iOS
All the warnings are factored out of the platform-specific files and moved to
SConstruct. Will have to check that it does not introduce regressions on some
platforms/compilers.
(cherry picked from commit 31107daa1a)
The ID property for InputEvents is set by `SceneTree` when sending the event down the tree.
So there's no need for the platform specific code to set this value when it will later be overriden anyway...
