SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Standardize and simplify the creation and editing of Defold native extensions by defining a common directory layout, required files, and language entry points, so teams can ship reliable extensions faster.

Core Features & Use Cases

  • Standard extension layout with ext.manifest and optional directories (src/, include/, lib/, api/, res/) to organize code and resources.
  • Guidance for cross-language extensions, including C/C++ and JavaScript entry points, and platform considerations across multiple targets.
  • Use Case: Create a native extension to extend the Defold engine with new functionality and expose it to Lua via a defined API.

Quick Start

Create your extension folder with ext.manifest and populate src/, include/, and lib/ for your target platforms, then add a C++ or JavaScript entry point and register the extension.

Frequently Asked Questions about defold-native-extension-editing

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is the required directory structure for a Defold native extension?▼

A Defold native extension requires an ext.manifest file alongside optional src/, include/, lib/, api/, and res/ directories to organize C/C++ or JavaScript code and resources correctly.

How do I set up a native extension in Defold to expose C++ code to Lua?▼

To expose C++ to Lua, create an extension folder with ext.manifest, populate the src/ and include/ directories with your code, define a C++ entry point, and register the extension API.

Can I use JavaScript entry points when building Defold native extensions?▼

Yes, Defold native extensions support JavaScript entry points alongside C/C++, allowing you to define platform-specific code and integrate it within the standardized extension directory layout.

How do I organize cross-platform libraries for a Defold native extension?▼

Organize cross-platform libraries by placing compiled binaries into the lib/ directory and ensuring your ext.manifest correctly references platform targets for proper initialization and resource access.

Does a Defold native extension need an ext.manifest file to function?▼

Yes, the ext.manifest file is required as it defines the extension's metadata and structure, enabling the Defold engine to correctly initialize and load the native extension components.

When should I add res/ and api/ directories to my Defold extension layout?▼

Add the api/ directory to define Lua-facing APIs and the res/ directory to include necessary resources, ensuring your extension correctly initializes and exposes functionality to the engine.
