godot-cpp is a C++ binding library and development kit for creating high-performance extensions and custom nodes for the Godot engine. It provides the necessary headers and framework to implement complex game logic and low-level systems using native code.
The project enables the development of GDExtension plugins, allowing native libraries to be loaded into the engine without requiring a full recompilation of the core software. It facilitates the creation of custom engine extensions through a system of native bindings that map C++ classes and methods to the internal engine database.
The framework covers API integration via class registration and signal binding, as well as editor integration for exposing member variables. It includes a CMake-based build system for multi-platform targeting, supporting cross-compilation for desktop, Android, and WebAssembly via Emscripten.
The build process incorporates integration testing and the generation of compilation databases for IDE support.
