Florian Rival 9db4d603a0 Refactor access to behavior/behavior shared data in the editor
Avoid having getters in the gd::Platform or the gd::Project, as they should not be responsible for this.
Instead, use gd::MetadataProvider to fetch the BehaviorMetadata.

GDevelop.js

This is the port of GDevelop core classes to WebAssembly+JavaScript. This allows 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.

How to build

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

Linux/macOS Windows
git clone https://github.com/juj/emsdk.git git clone https://github.com/juj/emsdk.git
cd emsdk cd emsdk
./emsdk update emsdk update
./emsdk install 1.39.6 emsdk install 1.39.6
./emsdk activate 1.39.6 emsdk activate 1.39.6
source ./emsdk_env.sh emsdk_env.bat
  • Launch the build from GDevelop.js folder:
    cd GDevelop.js
    npm install
    npm run build

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

-> ⏱ The linking (last step) of the build can be made a few seconds faster by specifying -- --dev. Be sure to remove it before building a release version, as this disable "link-time optimizations" of the generated WebAssembly module.

  • 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.

About the internal steps of compilation

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 with CMake 3.17+) (you can also compile using MinGW-32 using npm run build-with-MinGW).

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