spine-sdl

The spine-sdl runtime provides functionality to load, manipulate and render Spine skeletal animation data using SDL. spine-sdl is based on spine-c and spine-cpp, depending on whether you want to use a C or C++ implementation.

See the spine-sdl documentation for in-depth information

Licensing

You are welcome to evaluate the Spine Runtimes and the examples we provide in this repository free of charge.

You can integrate the Spine Runtimes into your software free of charge, but users of your software must have their own Spine license. Please make your users aware of this requirement! This option is often chosen by those making development tools, such as an SDK, game toolkit, or software library.

In order to distribute your software containing the Spine Runtimes to others that don't have a Spine license, you need a Spine license at the time of integration. Then you can distribute your software containing the Spine Runtimes however you like, provided others don't modify it or use it to create new software. If others want to do that, they'll need their own Spine license.

For the official legal terms governing the Spine Runtimes, please read the Spine Runtimes License Agreement and Section 2 of the Spine Editor License Agreement.

Spine version

spine-sdl works with data exported from Spine 4.1.xx.

spine-sdl supports all Spine features except premultiplied alpha, screen blend mode, and two color tinting.

Usage

1. Create a new SDL project. See the SDL documentation or have a look at the example in this repository.
2. Download the Spine Runtimes source using git (git clone https://github.com/esotericsoftware/spine-runtimes) or download it as a zip via the download button above.
3. If you are using C, add the sources from spine-c/spine-c/src/spine and spine-sdl/src/spine-sdl-c.c to your project, and add the folder spine-c/spine-c/include and spine-sdl/src/spine-sdl-c.h to your header search path. Note that includes are specified as #inclue <spine/file.h>, so the spine directory cannot be omitted when copying the source files.
4. If you are using C++, add the sources from spine-cpp/spine-cpp/src/spine and spine-sdl/src/spine-sdl-cpp.cpp to your project, and add the folder spine-cpp/spine-cpp/include and spine-sdl/src/spine-sdl-cpp.h to your header search path. Note that includes are specified as #include <spine/file.h>, so the spine directory cannot be omitted when copying the source files.

See the Spine Runtimes documentation on how to use the APIs or check out the Spine SDL example in this repository.

Example

The Spine SDL example works on Windows, Linux and Mac OS X. For a spine-c based example, see example/main.c, for a spine-cpp example see example/main.cpp.

Windows

1. Install Visual Studio Community. Make sure you install support for C++ as well as th Windows SDK for XP/7/8.
2. Install CMake via the Windows installer package.
3. Download the Spine Runtimes repository using git (git clone https://github.com/esotericsoftware/spine-runtimes) or download it as a zip via the download button above.
4. Run CMake GUI from the start menu
5. Click Browse Source and select the directory spine-runtimes
6. Click Browse Build and select the spine-runtimes/spine-sdl/build directory. You can create the build folder directly in the file dialog via New Folder.
7. Click Configure. Then click Generate. This will create a Visual Studio solution file called spine.sln in spine-runtimes/spine-sdl/build and also download the SDL dependencies.
8. Open the spine.sln file in Visual Studio
9. Right click the spine-sdl-example-c or spine-sdl-example-cpp project in the solution explorer and select Set as Startup Project from the context menus
10. Click Local Windows Debugger to run the example

The entire example code is contained in main.cpp

Linux

1. Install the SDL build dependencies
2. Download the Spine Runtimes repository using git (git clone https://github.com/esotericsoftware/spine-runtimes) or download it as a zip via the download button above.
3. Open a terminal, and cd into the spine-runtimes/spine-sdl folder
4. Type mkdir build && cd build && cmake ../.. to generate Make files
5. Type make to compile the example
6. Run the example by cd spine-sdl && ./spine-sdl-c-example (C) or by cd spine-sdl && ./spine-sdl-cpp-example (C++)

Mac OS X

1. Install Xcode
2. Install Homebrew
3. Open a terminal and install CMake via brew install cmake
4. Download the Spine Runtimes repository using git (git clone https://github.com/esotericsoftware/spine-runtimes) or download it as a zip via the download button above.
5. Open a terminal, and cd into the spine-runtimes/spine-sdl folder
6. Type mkdir build && cd build && cmake ../.. to generate Make files
7. Type make to compile the example
8. Run the example by cd spine-sdl && ./spine-sdl-c-example (C) or by cd spine-sdl && ./spine-sdl-cpp-example (C++)
