The Defold SDK

The Defold SDK contains the required functionality to declare a native extension as well as interface with the low-level native platform layer on which the application runs and the high-level Lua layer in which the game logic is created.

Usage

You use the Defold SDK by including the dmsdk/sdk.h header file:

#include <dmsdk/sdk.h>

The available SDK functions are documented in our API reference. The SDK contains the following namespaces with functions:

• Align - Alignment macros. Use for compiler compatibility
• Array - Templatized array with bounds checking.
• Buffer - Buffer API for data buffers as the main way to communicate between systems. Lua API for buffer creation also exists.
• Condition Variable - API for platform independent mutex synchronization primitive.
• ConfigFile - Configuration file access functions. The configuration file is compiled version of the game.project file.
• Connection Pool - API for a pool of socket connections.
• Crypt - API with cryptographic functions.
• DNS - API with DNS functions.
• Engine - API with core engine functionality to get handles to config files, the internal web server, game object register etc.
• Extension - Functions for creating and controlling engine native extension libraries.
• Game Object - API for manipulating game objects.
• Graphics - Platform specific native graphics functions.
• Hash - Hash functions.
• HID - API for generating programmatic input events.
• HTTP Client - API for interacting with a HTTP clients.
• Json - API for platform independent parsing of json files.
• Log - Logging functions.
• Math - API with mathematical functions.
• Mutex - API for platform independent mutex synchronization primitive.
• SSL Socket - API for secure socket functions.
• Script - Built-in scripting functions.
• Socket - API for socket functions.
• String Functions - API for manipulating strings.
• Thread - API for thread creation.
• Time - API for universal time and timing functions.
• URI - API for manipulation of URIs.
• Web Server - API for a simple high-level single-threaded Web server based on dmHttpServer.
• Shared Library - Utility functions for shared library export/import.
• Sony vector Math Library - The Sony Vector Math library mainly provides functions used in 3-D graphics for 3-D and 4-D vector operations, matrix operations, and quaternion operations.

The Defold SDK headers are included as a separate defoldsdk_headers.zip archive for each Defold release on GitHub. You can use these headers for code completion in your editor of choice.
