The API is implemented in javascript, and generates C functions that can
be called from godot.
This allows much cleaner code replacing all `EM_ASM` calls in our C++
code with plain C function calls.
This also gets rid of few hacks and comes with few optimizations (e.g.
custom cursor shapes should be much faster now).
The engine now expects to emscripten FS to be setup and sync-ed before
main is called. This is exposed via `Module["initFS"]` which also allows
to setup multiple persistence paths (internal use only for now).
Additionally, FS syncing is done **once** for every loop if at least one
file in a persistent path was open for writing and closed, and if the FS
is not syncing already.
This should potentially fix issues reported by users where "autosave"
would not work on the web (never calling `syncfs` because of too many
writes).
- Refactored the Engine code, splitted across files.
- Use MODULARIZE option to build emscripten code into it's own closure.
- Optional closure compiler run for JS and generated code.
- Enable lto support (saves ~2MiB in release).
- Can now build with tools=yes (not much to see yet).
- Dropped some deprecated code for older toolchains.
- Add onExit, and onExecute JS function.
- Add files drag and drop support.
- Add support for low precessor usage mode (via offscreen render, swap).
The value of this, does not include the layout.
The code has extra logic to map the unicode value to our keylist,
supporting ASCII and Latin-1.

At least in chrome, the following error is printed for each mouse wheel
rotation:
[Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive. See https://www.chromestatus.com/features/6662647093133312
This PR moves the handler to the canvas and thereby fixes the error.
Tested on: Chrome and Firefox (MacOS), Firefox, Chrome(Android), Safari (IPad + MacOS)
(cherry picked from commit b1e8ac7b08)
Without this patch, the following exception is thrown when the touch
screen is used: TypeError: e.getBoundingClientRect is not a function.
No touch events arrive in the engine.
From my testing, this PR fixes the issue and behaves as expected.
Tested with godot-demo-projects/misc/multitouch_view/, emscripten 1.39.8
and Firefox mobile emulator as well as FF on Android
(cherry picked from commit 5134317afc)
Fixes compatibility with emscripten 1.39.5+ .
Most input callbacks now require a target and no longer support NULL
defaults.
This commit changes all required null targets to the expected default in
the binding phase.
Since for canvas-related callbacks there is no default, the "#canvas"
selector is used instead.
Additionally, since canvasX and canvasY event properties are no longer
supported, event positions are computed from "clientX" and "clientY" and
the "#canvas" bounding client rect.
It was removed as noted in the changelog:
https://github.com/emscripten-core/emscripten/blob/1.39.5/ChangeLog.md#v1395-12202019
> Removed `timestamp` field from mouse, wheel, devicemotion and
> deviceorientation events. The presence of a `timestamp` on these
> events was slightly arbitrary, and populating this field caused
> a small profileable overhead that all users might not care about.
> It is easy to get a timestamp of an event by calling
> `emscripten_get_now()` or `emscripten_performance_now()` inside
> the event handler function of any event.
Fixes#34648.
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.
This is a new singleton where camera sources such as webcams or cameras on a mobile phone can register themselves with the Server.
Other parts of Godot can interact with this to obtain images from the camera as textures.
This work includes additions to the Visual Server to use this functionality to present the camera image in the background. This is specifically targetted at AR applications.
It's not necessary, but the vast majority of calls of error macros
do have an ending semicolon, so it's best to be consistent.
Most WARN_DEPRECATED calls did *not* have a semicolon, but there's
no reason for them to be treated differently.
Being async, the first time a value is pasted GUI elements will still
return the previous one.
This at least until 'clipboardchange' window event gets implemented by
user agents.
Listen to paste events to update local clipboard.
CTRL+V still not working out of the box.
To do that, We would need to change how we handle keypress, most likely
making it worse and less safe. In the end, I'm not sure we can fix it
properly for now. Maybe in the future, with the Clipboard API, support
of which is still pretty limited on chrome, and only available to
extensions in Firefox.
For now, you can paste via:
- Browser bar -> Edit -> Paste.
- Middle mouse click (Linux only, copies secondary clipboard).
And THEN press CTRL+V
GLES2 is not designed to be a drop-in replacement for the GLES3 backend,
so the fallback mode has to be used knowingly. It *can* make sense for
simple projects which make sure to handle the differences between both
rendering backends, but most users should stick to one supported backend.
By making it opt-in, we can now use this parameter to define whether to
export ETC textures to Android and iOS when using GLES3 + Fallback.
When using GLES3 without Fallback on Android, set the proper min GLES
version in the AndroidManifest.
Also made the option boolean and renamed it for clarity and to avoid
conflict with the previous String option (which would always evaluate as
"true" otherwise).
Fixes#26569.
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.
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
-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
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`
Whether to use WebGL 1.0 or 2.0 can only be determined at runtime after
reading project settings, so check for the lower version.
The test is now in the HTML file, so if desired WebGL 2.0 can be
checked early by changing the behaviour there.
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.
Rename engine.start() to startGame(), new start() takes string arguments
handed directly to main(). Rename Engine.loadEngine() to load().
Add setLocale(), setResizeCanvasOnStart(), setExecutableName() and
preloadFile().
This makes the interfaces available, without implementation, in other
platforms and the editor, which facilitates documenting platform-exclusive
classes.
Platform-exclusive APIs must be set up in platform/<platform>/api/api.cpp.
Provide noop method-implementations where necessary.
Also setup and document the HTML5 platform's JavaScript singleton.
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.
