This is the port of GDevelop core classes to JavaScript. This allow GDevelop Core libraries to run in a browser or on Node.js.

🎮 GDevelop is a full featured, cross-platform, open-source game development software requiring no programming skills. Download it on the official website.

👋 Usually if you're working on GDevelop editor or extensions in JavaScript, you don't need rebuilding GDevelop.js. If you want to make changes in C++ extensions or classes, read this section.

• Make sure you have CMake 3.5+ and Node.js installed.

• Install Emscripten, as explained on the Emscripten installation instructions:

• Launch the build from GDevelop.js folder:

    cd GDevelop.js
    npm install
    npm run build

ℹ️ Output is created in /path/to/GD/Binaries/embuild/GDevelop.js/ and also copied to GDevelop 5 IDE (newIDE folder).

⏱ As the linking (last step) of the build can be very long, you can run npm run build -- --dev to disable temporary optimizations and get a (slightly) faster build.

• You can then launch GDevelop 5 that will use your build of GDevelop.js:

    cd ..
    cd newIDE/app
    npm install
    npm start

More information in GDevelop 5 readme.

npm test

The npm build task:

• Creates Binaries/embuild directory,
• Launches CMake inside to compile GDevelop with emconfigure to use Emscripten toolchain,
• Updates the glue.cpp and glue.js from Bindings.idl using Emscripten WebIDL Binder,
• Launches the compilation with make (or ninja on Windows).

See the CMakeLists.txt for the arguments passed to the Emscripten linker.

• The file Bindings.idl describes all the classes available in GDevelop.js.
• Refer to GDevelop documentation for detailed documentation of the original C++ classes.
