A change in upstream Emscripten 1.39.1+ made our buildsystem error
out where it was previously only issuing a warning:
```
[ 5%] Linking Static Library ==> main/libmain.javascript.opt.bc
shared:WARNING: Assuming object file output in the absence of `-c`, based on output filename. Please add with `-c` or `-r` to avoid this warning
Ranlib Library ==> main/libmain.javascript.opt.bc
/opt/emsdk/upstream/bin/llvm-ranlib: error: unable to load 'main/libmain.javascript.opt.bc': file too small to be an archive
```
As advised on emscripten-core/emscripten#9806, we should be using
`emar` here to create the static library and not `emcc`.
This was apparently done to workaround Emscripten issues in the past,
but evidently this is no longer necessary.
The rest of the `env` redefinitions should probably be re-assessed
against the current state of Emscripten.
Fixes#33374.
Since most browsers no longer allow making async requests from a page
loaded from `file://`, we now need a proper HTTP server to load the
exported HTML5 game.
This should also allow us to get the debugger to work over a WebSocket
connection.
- Add or remove the necessary subdirectorires to the includes to remove
dependency on the editor directory being in the build's include path.
- Ensure includes in modified files conform to style guideline.
- Remove editor from the build include path.
So far we left most temporary files lying around, so this attempts to
fix that.
I added a helper method to DirAccess to factor out the boilerplate of
creating a DirAccess, checking if the file exists, remove it or print
an error on failure.
It is not supported in Emscripten's `latest-upstream` LLVM backend,
and doesn't seem necessary in the `latest` backend either.
It was initially added in #22857 to solve a compilation error with the latter.
Part of #30270.
Emscripten is apparently changing the variables in its config file,
causing potential breakage of our build system.
Binaries of the latest/latest-upstream releases are located in a
subfolder of BINARYEN_ROOT called emscripten.
Binaries of the other releases (e.g. sdk-1.38.31-64bit) are instead
placed under the EMSCRIPTEN_ROOT folder.
This PR checks if BINARYEN_ROOT has a subfolder called emscripten, if
that does not exists, it falls back to checking the EMSCRIPTEN_ROOT.
This way we give precedence to the new releases, given that activating
multiple releases sequentially might result in having mismatching
BINARYEN_ROOT and EMSCRIPTEN_ROOT.
Recent Emscripten SDK versions seem to only include the
`BINARYEN_ROOT` variable in the Emscripten configuration file,
whereas the platform's `detect.py` only looked at `EMSCRIPTEN_ROOT`.
Warnings raised by Emscripten 1.38.0 and MinGW64 5.0.4 / GCC 8.3.0.
JS can now build with `werror=yes warnings=extra`.
MinGW64 still has a few warnings to resolve with `warnings=extra`,
and only one with `warnings=all`.
Part of #29033 and #29801.
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
Those were disable to keep size small, and on Android avoid the dependency on the STL,
but for tools build (editor) this is not really a concern.
Note: as of today it's not possible to build tools=yes for those platforms, but this
change is one of the necessary steps to enable it.
Fixes#25262.
Include paths are processed from left to right, so we use Prepend to
ensure that paths to bundled thirdparty files will have precedence over
system paths (e.g. `/usr/include` should have lowest priority).
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.
For HTML5, we need to support S3TC if running on desktop,
and ETC or ETC2 for mobile, so make this explicit.
Add logic to check for ETC2 support on GLES3,
and remove incorrect ETC feature for GLES3 on Android.
Fix ETC check invalidating templates on HTML5.
Fixes#26476.
The code in pre.js and engine.js is a bit confusing to see in isolation,
since the files aren't valid JS files by themselves. This just adds some
explanatory text to both files.
Fixes#22937.
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
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
