currently Felgo games are written in QML, you can however already enrich your games with C++ components for desktop platforms. Full C++ support and custom plugins are on our roadmap for Q3/Q4 this year.
Out of interest, what would be your main use cases for using C++ code?
Ok i see, looks like a cool approach for animations! We’ll have a deeper look at the project, probably we can integrate it into the engine core directly. Probably you can post this one to our roadmap thread too?
