Projectiles are one of the things that I haven't touched at all. The code just seemed to work perfectly on Day 1, but now you've made me curious. I suspect something is going on with collision masks.
I want to ask you, is there any interest in the community for Industrial Revolution 2, or even 1? I'm thinking of Python 2 vs 3 where Python 2 has a few stalwart users after all these years. There's no way I'm going to start working on them soon, I'm just curious.
Going through my memory, I (and probably most of us) first read about the mod in this FFF post, where in the second half, Bilka describes its game design in some detail. At this point, I had only heard of some "Angel Bob" thing; I didn't know such comprehensive overhaul mods existed.
I did try IR2 very briefly and bounced right off of it. It was my first time installing a Factorio mod and it was too hard for me. Even Space Age has been a bit stressful, but I did find Krastorio 2 to be around the right level of difficulty.
Also somewhat amusing is all the previous times where Deadlock has said he's finished with the mod and isn't coming back, and then he returns months later with IR2. And then the same thing again with IR3 in 1.1.
One last thing which I noticed: IR3's first version was released on Christmas Eve 2022, and I uploaded this Patchset to the portal on Christmas Day 2025, 3 years later. I didn't know, I swear it!
