Exporting for the Web¶
Exporting for the web generates several files to be served from a web server, including a default HTML page for presentation. A custom HTML file can be used, see Compiling for the Web.
The default HTML file is designed to fit the game perfectly without cutting off
parts of the canvas when the browser window is scaled to the game’s dimensions.
This way it can be inserted into an
<iframe> with the game’s size, as is
common on most web game hosting sites.
Serving the files¶
.html file can be used as
DirectoryIndex and can be
renamed to e.g.
index.html at any time, its name is never depended on.
It can also be inserted into another HTML file as an
Users must allow third-party cookies when playing a game presented in an
.pck files are binary, usually delivered with MIME-type
Delivering the files with gzip compression is recommended especially for the
.mem files, which are usually large in size.
Memory Size is fixed and must thus be set during export. Try using no more than necessary to strain users’ browsers as little as possible.
Enable Run will add a button between the Stop scene and Play edited Scene buttons in the editor to quickly open the game in the default browser for testing.
The remaining options customize the generated HTML page:
Title is the content of the
<title> element of the page, usually used by
browsers as the tab and window name. The title set here is only displayed until
the game is started, afterwards the title is set to the application name set in
the project settings.
Head Include and Style Include are appended into the
<style> elements respectively. This allows, for example, linking
web fonts for use in the page.
Font Family is the CSS
font-family used on the page, without terminating
Controls Enabled toggles display of controls, offering e.g. a toggle for output display in debug mode and a fullscreen button. In the default page, the controls are displayed in the top-right corner on top of the canvas, which can get in the way in games that use the cursor.
Browsers do not allow arbitrarily entering full screen at any time.
In Godot, this is most easily done by entering full screen from within an
Chromium-derived browsers will not load exported projects when
opened locally per
file:// protocol. To get around this, you can start
the browser with the
--allow-file-access-from-files flag, or use a local
server. Python offers an easy way for this, using
python -m SimpleHTTPServer
with Python 2 or
python -m http.server with Python 3 will serve the
current working directory on
Godot tries to detect the user’s locale using information provided by the
browser, but this is rather unreliable. A better way is to use CGI to read the
Module.locale after the
Module objects is created, but before
the engine starts, Godot will use that value to initialize the locale.
In any case, users should always be offered the option to configure the locale
