This file defines the mapping between a Python module named “ogre” and the classes and functions we want to make available. Switch to the ogre_module.h file to see what we did for this sample. It is very easy to make Python representations of your C++ classes with pybind11. So rather than launching “python.exe” with a script, you can load python36.dll into your own application and use it directly. Embedding allows you to host the Python runtime in any native application, on any platform and using any compiler supported by CPython. This is possible because of CPython’s support for embedding, and made simple by the powerful pybind11 library. Compare this to normal C++ development, where you would have had to stop running, modify the code, recompile (and wait!), start running again, and return to the same state you were previously. The F5 key will reload the script, and you will see your changes (or an error) immediately. Once you’ve made changes, save this file, use Alt+Tab to go back to the running sample, and press F5. You can do this while the demo is running in the background. There are already some extra movements listed but commented out, so try uncommenting them or adding your own. Each item in this list is the movement we want Sinbad to do, including the amount of time he should do it for. Collapse the command definitions region by clicking the “-” symbol to the left of #region Command definitions and look at the SCRIPT variable. The Python module ai.py is where we define the behavior of Sinbad, our dancing ogre. We will be looking at each in the next few sections. In Visual Studio, open Solution Explorer and then open the following files. We will do that next to look at some of the code. While running, the sample will capture your mouse cursor, but you can use Alt+Tab to switch to another window.
Once everything is installed, open srcPythonCharacter.sln in Visual Studio 2017 and press Ctrl+F5 to build and run the sample.

There is a PowerShell script in the root of the repository called get_externals.ps1 that will download and extract the version of the Ogre3d and SDL2 runtimes needed, and will prompt if you are missing either Python 3.6 32-bit or the DirectX redistributables (you can download the latter here, but be aware that this is a very old installer that will offer to install a browser toolbar – feel free to deselect that). If you have already installed it, you can use Programs and Features to modify your install and add debugging symbols.Ĭlone our repository using git clone -recurse-submodules or using Team Explorer in Visual Studio. If you install it yourself, you will need to select “Customize installation” and include debugging symbols. Note: When you install Python 3.6 32-bit through Visual Studio, it automatically includes debugging symbols.
If you already have Visual Studio 2017, these can be added by launching “Visual Studio Installer” and modifying the existing install. To build and run this sample on your own machine, you will require Visual Studio 2017 with the Python workload, the Python Native Development option, and Python 3.6 32-bit.

Rather than using the keyboard to move the character around, we can use Python code to call into the C++ functions that control him. For this sample, we have taken one of their character animation demos and extended it with Python. Both the engine and its source code are freely available from their website. Ogre3d is an open-source game engine written in C++ that has been used in games such as Hob and Torchlight 2. The sample code is available at /zooba/ogre3d-python-embed and setup instructions are below. In this post, we’re going to walk through a sample project that demonstrates scripting a C++ application with Python using CPython, PyBind11 and Visual Studio 2017.
