Engine with C++ scripting?
You know that c++ is not a scripting language?
Perhaps you should try python instead! With pygame2.
Or maybe do you mean a C++ engine with a scripting language support (Python/Lua/AngelScript)?
i know c++ isn't a scripting language. but we want to learn C++, not py,lua etc. And you are right that is a mistake
Thanks for your suggestion. I will look up Source Engine. But I think 3D games are too hard for us. I think start with basic 2D platform games. What do you think about 2D platform or 3D FPS?
Maybe you should take a look at Angel2D. It was made for game jams and prototyping, so some design options are not the most efficient or good ones, but I would say it's nice for beginners. I would suggest you start by extending the Actor class and slowly create some small things. But you will still need to understand C++, this tutorial was enough for me to get started with some fun parts. If you don't mind using the C-style library SDL I would suggest you take a look at this tutorial series.
For C++ interpreters, there is CERN's CINT project (http://root.cern.ch/drupal/content/cint) which supports scripting in both C and C++.
I really like it and use if for our expansive build system at work but I personally would not use it for creating games.
There is also Pico C (http://code.google.com/p/picoc) which looks much more usable for game scripting (though you would need to hook it up to the chosen engine manually). It is C only (no C++) but with the popularity of the component entity system these days, OOP is not really critical IMO.
If I were, you, I would do without the scripting part and look into something like Irrlicht. This is simply a 3D engine with a C++ API. Yes, a lot of people seem to not like it but frankly, the license, the ease of use and the portability of it is great for beginners.
The GoldSource engine was quite cool for mod development before Steam/DRM came along but you will need pretty decent knowledge of C/C++ before you will be productive using it. It doesn't spoon feed you unlike products like Unity or even in some respects like Irrlicht (less tutorials, documentation etc...).
The most popular seems to be SFML, you can use orx with C++ too, orx is a great engine if you like to use ini files like I do.
