[Lou] [2.0.15] Railgun is shooting other Railsguns
Re: [Lou] [2.0.15] Railgun is shooting other Railsguns
I'm still seeing issues with this even on 2.0.39. I'm trying to get a recording of it happening, but it occurs rarely (and I'm not even sure exactly where on my platform it's happening), so it may take a bit.

Could you post a blueprint of the platform or the savefile?Orum wrote: Wed Mar 12, 2025 3:01 pm I'm still seeing issues with this even on 2.0.39.

I will upload a save when I get back home. There are two things that make reproducing this very annoying, however.
First is that this seems to occur very rarely. When I tested a trip all the way to the shattered planet, which takes my platform around 2.1 hours, it only happened once. As for what happened, the railguns killed one of the asteroid collectors they shouldn't have been able to hit. How do I know it was railguns and not asteroids? Well, the game doesn't make any alert sounds when something is killed by friendly fire, and I heard nothing—not to mention harmful asteroids don't get anywhere near my platform.
I reloaded an autosave before it happened, in the hopes I could see it happen again, but this is where the second issue comes into play: non-determinism. Even though I never did anything during the entire flight to the shattered planet (other than bringing up the production stats screen), after reloading the save and finishing the flight to the shattered planet again, it didn't occur. As such, reproducing the issue is extremely hard, at least in a timely manner.
Further exacerbating the problem is video recordings of the front of my ship require insane amounts of bitrate to prevent it from turning into mush. As in, literally hundreds of Mbit/s. I'm looking at setting up loop recording in OBS so that I don't have to keep hours of video at this bitrate, which I don't have the space for. And finally, the game also runs very slowly unless I use graphical mods to reduce the load on my GPU, so doing this in an unmodded Factorio is basically out of the question.

The save could be very useful even without the recording.Orum wrote: Wed Mar 12, 2025 9:24 pm ...

Oops, I forgot to upload the save file a while ago. Well, better late than never: link.
Note that this is saved without the performance enhancing mods enabled, the most important of which is "Remove Asteroid Particles". I also have used "FPS Friendly Thrusters" and "Remove Weapon Particles" but the performance enhancement from them is minor compared to removing the asteroid particles. The FPS hit is worst when zoomed out as far as you can be (before it turns the graphics to just rectangles of mono-colored pixels) and looking at the front of the ship & the asteroids in front of it. I'll also note that I'm using "Texture compression" set to "None" as I noticed artifacts even when it's set to "High quality", and this probably doesn't help things (as I suspect it's probably memory throughput bound, even on my 4080 Super).
Anyway, just go to the platform parked at the shattered planet and tell it to leave, and if you get unlucky (or lucky, depending on if you're trying to reproduce the bug or not) it might shoot part of itself with a railgun on the way back.
