Factorio Forums

Hi,

Factorio is a great game, I'm love it.
I'm curious about game programming.
Can I ask some question?

1. Why Allegro? Why not SDL, Cocos2d-x, SFML...etc
2. What version at Allegro? 4 or 5? And why?
3. Your programming architecture have use MVC? or like it? (it's mean split logic and view, if you delete code about view, the game logic still running)

If the topic does not fit appear at here, please tell me where i can go? I'm really very interested.

Because it was the first engine that came to my mind. As Factorio started as small hobby project, I didn't put so many thought into it.

5 and the newest version, sometimes even the git version. We also have some custom changes made in Allegro. Mainly optimisation and font changes.

It is especially needed to achieve deterministic simulation in multiplayer independent on the view.

Thank you for your reply. It's very helpful for me.
