This game is inspired by Maxis's SimFarm (1993). However, it has the ambition of being more realistic both in agronomic and in a financial way. That means that I am trying to create a model for a crop that responds to the environment (soil, weather, diseases, fertilizers, pesticides, hydric stress, etc) and also a model for the economic system where you have to buy and sell in a very competitive market. For the first version, I will focus on coffee crops. I had to do this because, in the level of realism that I am trying to achieve for the crop models, two different cultivars have very different logic behaviors. However, I'm trying to structure it in such a way that it can be easily extensible for other crop models.
It's the first time I´m using the Godot engine, and it's the first time I´m making a game from scratch at all. So I am pretty sure that it will have a lot of issues in logic and performance at first, which I will try to address while developing the game core.
Godot is a wonderful open-source game engine, written in C++ and in GodotScript, which allows you to create games using a GUI and codes in GodotScript (python-like) or C#. It is also possible to write code in C++ and integrate it with Godot. I don't know how to do it yet, but it is something that I surely will do to solve some performance and code cleanness issues: Instantiating many crops at the same time is currently taking to long; Godot Script has a week OOP structure, and I'm missing Interfaces and Abstract Classes very much, which I believe will be a problem when I try to add other cultivars beside coffee.
If you want to contribute to this game, you can understand how its working now by the diagrams on the Coffee Crop Model document. All that functionality is implemented in the Crop.gd script
Coffee Crop Model (currently in portuguese).
