I'm looking for an AGS engine plugin that would let me use any third-party language, do do stuff that I can't do with AGS.
There use to be quite a few : Lua, Python, C#...
However it seems that all of them are now lost, broken or not compatible with the latest AGS.
Does anyone have a suggestion?
You can write in C++, inside plugin itself :).
I am not sure what sort of stuff you can't do in AGS, maybe narrowing exactly what you are looking for?
