Performances are not great in general, bad on Firefox, on Chrome, well,
it's an improvement compared to the way they broke ScriptProcessorNode.
I'm actually surprised this works, it involves so many allocations, but
there's no way around it when SharedArrayBuffer is not available :(.
After input buffering was reworked, input accumulation is now handled
outside of OS, and the JavaScript plaform never implemented that.
Additionally, the JavaScript platform is quite obnoxious about calling
specific APIs outside specific user triggered events.
This commit adds event flushing during the main iteration, and forces it
during keydown/keyup/mousedown/mouseup/touchstart/touchend/touchcanel
events (effectively only accumulating only "move" events).
This uses the `event.code` value to retrieve the physical code, while
still using the extra logic to map the unicode value to our keylist,
when computing the `scancode` (supporting ASCII and Latin-1).
Added as an export option "Experimental Virtual Keyboard".
There is no zoom, so text/line edit must be in the top part of the
screen, or it will get hidden by the virtual keyboard.
UTF8/Latin-1 only (I think regular UTF-8 should work out of the box in
4.0 but I can't test it).
It uses an hidden textarea or input, based on the multiline variable,
and only gets activated if the device has a touchscreen.
This could cause problems on devices with both touchscreen and a real
keyboard (although input should still work in general with some minor
focus issues). I'm thinking of a system to detect the first physical
keystroke and disable it in case, but it might do more harm then good,
so it must be well thought.
Three canvas resize policies:
- `None`: Godot window settings are ignored.
- `Project`: Godot handles the canvas like a native app (resizing it
when setting the window size).
- `Adaptive`: Canvas size will always adapt to browser window size.
Use `None` if you want to control the canvas size with custom JavaScript
code.
`OS.get_screen_scale` will now return the `window.devicePixelRatio`
value, `OS.get_screen_dpi` uses CSS media queries to find approximate
DPI value for the current display.
`OS.get_screen_size` also return the actual screen size (not the CSS
pixel size).
The canvas_id is `#`-prefixed to work with emscripten as a CSS selector.
When comparing to an event target ID (e.g. when checking if the canvas
is fullscreen, or is locking the mouse) we need to skip the first char
(the hash).
No longer use emscripten functions for gamepads, implement them as
library functions in library_godot_display.js instead.
This allows us to do a better job at "guessing" vendorId, productId, OS,
etc. thus allowing us to better find the remapping for the controller.
Happy new year to the wonderful Godot community!
2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.
We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)
Here's to a great year 2021 for all Godot users 🎆
(cherry picked from commit b5334d14f7)
This was caused by the devicePixelRatio being applied twice, once by the
HTML code, once by the OS code.
More specifically, OS.get_window_size() would return the canvas element
size, while OS.set_window_size() would set the element size to the
specified value times the devicePixelRatio.
Calling OS.set_window_size(OS.get_window_size()) would reapply the
devicePixelRatio every time.
This commit changes the behaviour so that OS.set_window_size() do not
apply the devicePixelRatio to the canvas element size, by it divides the
CSS size instead.
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.

Similar to https://github.com/godotengine/godot/pull/36557
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.
