How to enable scripting in my engine

Alice · 2018-07-13T08:00:21

Hello, I am designing my own game engine just as a hobby in c++. I like the language of c++ but for development speed for actually making a game with the engine i wish to use simple language like c# or python to script game objects. Can anyone point out any free online resources or link to forum posts that would help me understand how to enable my engine to use other languages to script with please. It would be very much appreciated. Thanks Alice

Lua really has a minimalist philosophy in letting it be used in many ways. Unless you're a minimalist fan yourself and a C programmer, the push/pop VM stack stuff should only be used by a binding library for your language (e.g. a Lua<->C++ binding layer).

Lua also lacks class-based OOP facilities out of the box, but has all the tools required to build a class system yourself.

If you're high level OO programmer, then yeah, vanilla Lua is probably too minimalist, but... Lua plus a few additional libraries does bridge the gap.

While I love getting down and dirty with code, there's something to be said about higher level languages. I would much prefer Ruby or Python over LUA. Does anyone here have any experience binding them to C++?

I would just like to say thank you to all those who have contributed to this post. I am reviewing all of the information.

I have noticed that LUA doesn't take advantage of OOP, does anyone know of how to say use Python for a scripting language rather than LUA or maybe C#.

I would like to retain as much OOP as possible.

Thank you so much guys

There's lots of options. Check out this SO thread on the topic : https://stackoverflow.com/questions/145270/calling-c-c-from-python

You can download the source code of the mono project, they also have a compact version of mono runtime available as C/C++ source. This will be able to load and run .Net assemblies in a more or less supported way.

A project that uses mono to make C# available to HTML/Javascript for example is Electron.

Related to this block post, it seems to be very easy to include the mono runtime into any C/C++ based application so try it, I will do the same (later)

Looks like you prefer the larger, more complex languages like Python, Ruby, or even C#. Personally if I go with that route, I'd instead write majority of code in the scripting language and only create a C/C++ function (with binding) in the area that needs performance.

This is of course an opposite to the embedding method (which majority of code is written in C/C++, and use scripting language only in the area that needs customization like the AI code). In this case I'd use Chaiscript or Lua.
