Over the past few months, I have been researching and developing a little procedurally generated game which will eventually be created in the Godot engine. This game will have a story that’s procedurally generated for the players. A part of this game is the dialogue, which will also be procedurally generated. To accomplish this, I set out to find a library of some kind which can create procedurally generated dialogue (or at least the dialogue that I want) and is written in my programming language of choice, Python. From the looks of it, there isn’t one, and so I had to look elsewhere. That’s when I stumbled upon something called Rant. This is billed as a library which can procedurally generate dialogue. At first I thought I had found what I was searching for. Sadly, though, it is written in the least open source-friendly language I have ever seen: C#. This can be used on Linux (with the Mono runtime). But I’m looking for a solution where I don’t have to use a bunch of programming languages to achieve what I want.
At first, I tried making some kind of dialogue scheme that would suit my needs. I threw in some sentences of what may define the NPC, and mashed it all together. From the looks of it, though, the scheme is getting out of hand. I have several lines of dialogue, and I’m not even finished. I don’t entirely know how I’ll fit it all together, considering this is just for a simple demo of the full game. It looks like I’m going to have to get creative.
I went digging and searching around I came upon several possible ways of integrating C# code into Python code. There’s IronPython, a fully implemented version of Python in C#. The big problem with this was that it didn’t look very portable to me, as I would have to bundle the .NET libraries with the game for each platform, and that’s a royal pain the ass. Then I looked at Python.NET, which looked very promising: you can call some C# code from Python, and you can call some Python code from C#. It looked like the best of both worlds. Now, actually making it work is a bigger problem.
When I tried to use the
Rant.dll assembly in my Python program, I found that I can’t do that because, well, it’s C# code, and the regular old CPython (which comes with many Linux distributions) can only import C or C++ code. Then I looked into using the
clr module from Python.NET, but I couldn’t find a version built for Linux. Through a lot of hand wringing, brow beating, and code cracking, I found that I had to use the latest version of Mono (version 5.0.1) along with an unstable version of Python.NET. This one built with the suggested command:
python setup.py build_ext --inplace. The built shared object library file, “clr.so”, and the “clr” module load in Python. Heck, I was even able to load the pre-built “Rant.dll”. But this is nothing compared what I must do now: actually making some procedurally generated dialogue with Rant. And I don’t know where to begin with that.
