sol2 VS SSVOpenHexagon

As someone said, make the game data-driven is a good first step but I will say, also have some sort of way to add additional game logic. For C++ games, lua is really easy to embed the interpreter in your C++ binary, read in the files from a directory (like /mods) with the C++ filesystem api new in C++17, and it's very easy to use SoL to write an API for lua specific to your game. Many games use lua in this way and it's probably the most common mod path setup.

I've only ever done this from C++, but it's using the same lua C library, so should be durable from C as well. You can look up how sol2 or any other wrapper libraries do it.

Consider sol2

This version relies on a Lua C++ wrapper called sol2 to hide Lua stack management from the developer, so creating new bindings can be done by adding a few lines of human-readable C++. It still has to be done manually, but at least sol2 is able to automatically figure out types of objects being bound, so it's not much different from our de-/serialization code.

Here's an example: sol2

Here is link number 2 - Previous text "Sol"

Have you considered using sol2? https://github.com/ThePhD/sol2 Or if you don't want to switch over, you can at least look at their code and see how they handle this.

It is half of a pun as I was inspired by [sol3](https://github.com/ThePhD/sol2) which is a lua <-> c++ wrapper. Sol means sun and the julia c-api prefixes all it's functions with jl, luna means moon so it is pronounced "jay luna"

If you want to be portable I'd recommend C++ and Lua, I used those for years and it runs on everything and there's this most amazing wrapper API which was a huge inspiration

Open Hexagon, re-implementation of Super Hexagon

Yeah, that is interesting. The github page is under an AFL license which contradicts his Steam EULA in multiple ways.

Open Hexagon

https://github.com/vittorioromeo/SSVOpenHexagon

Space Station 13 (and the remake, SS14) is an incredibly unique and feature rich multiplayer role playing game that takes place on a rickety space station in a wacky retro-futuristic setting. It's hard to recommend this game as the learning curve is more like a cliff, but it is far and away the best game that exists for creating unique (and often very funny) stories in. It has a long and complicated open source history that has fragmented it into several unique popular forks, but the most popular one that's fully open source nowadays is tgstation.

it's a clone of SuperHexagon (2012)

The product is dual-licensed -- the Steam version has an EULA, the GitHub repository is AFL Licensed.

The source code of the game is available here: https://github.com/SuperV1234/SSVOpenHexagon/

I was wondering if Open means truly Open - and it does https://github.com/SuperV1234/SSVOpenHexagon
