Use an offline first approach, where we prefer the cached version over
the network one.
This forces games using PWA to always re-export the project and not just
the PCK, so that the service worker version gets updated correctly, and
the end-user cache is correctly cleared on update.
The logo's maximum width is now dependent on the viewport height
in addition to the page width. This prevents the "Start Godot editor"
button from overflowing the page on mobile devices (although the
"Clear persistent data" and "Web editor documentation" buttons will
still overflow for now).
This makes for a more seamless-looking address bar/status bar
when using the web editor on a mobile device, either directly
in the brower or installed as a progressive web app.
This also specifies a theme color for the web editor's offline
fallback.
Note, the editor build requires the mbedtls module to be manually
enabled, as it is currently needed as a ResourceUID dependency.
This will need to be addressed in a separate PR.
Default is "Auto", but can be forced to a specific WebGL version if the
automatic detection fails.
The game and editor canvas are now replaced with a new one in the exit
hooks. This helps the browser do some context cleanup, and allow us to
create a new context of a different type (WebGL/WebGL2).
We used to only generate the favicon if it was specified in the user
project settings, now it's optional, will export it to `NAME.icon.png`,
(falling back to the default project icon if none is set in project
settings), and the `<link>` tag is added using the `$HEAD_INCLUDE`
instead of being hardcoded in the template.
- Consistently use double quotes in the HTML markup.
- Define English language to assist screen readers and search engines.
- Add missing `alt` text for the logo image.
- Remove duplicate `id` for the preload project ZIP input.
This modal dialog displayed when the page is loaded. It can be
dismissed permanently by clicking the "OK, don't show again" button.
Clicking outside the modal will only dismiss it once.
This dialog is used to remind people that the HTML5 editor is still in
release candidate stage and isn't considered production-ready yet.
With a very nice hack, a new hidden configuration option that delays
dropped files removal at exit.
This still leaks while the project manager is running, but will clear
memory as soon as it exits or load something.
(reminder, dropped files are reguarly removed after the signal is
emitted specifically to avoid leaks, but I prefer hacking the HTML5
config then the project manager).
This allows to install it as an app, and provide offline support (after
the first run).
Practically, this boils down to adding a JSON file as a manifest, an
offline page to be displayed when the cached files are not avaialble,
and a JS file to cache resources and return them.
The reason for the "first run requirements" is that some browsers, will
emit an "install" by just visiting the page (to see if the JS code is
compatibile), and we do not want to force casual visitors to just
download the 10 MiB+ compressed editor WebAssembly file without pressing
the start button.
Special thanks to Hugo Locurcio (Calinou) for the initial work.
We used to have it like `$GODOT_VERSION` which caused inconsistencies
between different scons versions when substituting it.
It's now `@GODOT_VERSION@`, which is safe on both scons3 and scons4.
- Darken the header tab background to match the default editor
background color.
- Hide the distracting focus outlines for the editor and game canvas.
- Use a pure black background for the game canvas to better distinguish it
from the editor and provide a more neutral background.
- Use a bold font weight for the Start Godot editor button on the
loader page.
- Link to the web editor documentation on the loader page.
- Clarify what happens when clicking "OK" in the persistent data removal
warning dialog.
- Tidy up the HTML template by removing obsolete attributes.
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.
We used to only persist specific sub-folder of /home/web_user/ when
running the Web Editor. This resulted in bad UX about default project
creation path etc.
This PR makes the whole folder persistent, move the zip preloading to a
different folder (to avoid persisting it), and automatically prompt the
user to import it if present.
