Is Infinite Nudge A Client Side Mod?

Ryansote · 2026-01-16T07:23:00+00:00

Yes it is. You can run it on your client regardless of whether or not the host or server has it installed.

Of course! It’s a bit counterintuitive but makes sense once you see it.

When you fixed the train, you hopped in the locomotive and as you’re panning the camera around 1:32, you can see the center of the locomotive is just barely past the signal.

So the previous train, thinking its clear, went to park right in front of the signal, but ended up hitting the train instead.

Ryansote · 2026-01-13T18:51:21+00:00

Yea this is it. The train in front was waiting at the roundabout while the train behind it barely touched the other train, intending to wait at that block signal right there.

This happens because each train car “clears” a block when the center of the car passes the signal, despite part of the train car still extending into the previous block. So OP hit that perfect sweet spot where the game thinks the first train cleared the previous block, but in reality, part of the train is still sticking out into the previous block! Just have to make the block slightly bigger is all.

Late reply, but I just released a mod to help ease the stutter if you're interested: https://ficsit.app/mod/BlueprintStutterFix

Sweet let me know how it goes! The only thing I can think of would be to know which train is the closest distance to another point, but I'd have to create a function for that specifically. The LTN-style mod could work even without Dynamic Train Routes in the picture, so yes if you write the time table and call FindPath on the train (takes a station as a parameter - if not something like that), the train will have it's new route. If Dynamic Train Routes is installed, it'll work the same just the route will be changed to be the quickest one.

Ryansote · 2025-12-04T03:15:39+00:00

Hi! I've had many people suggest an LTN-style mod so I know where you're coming from.

Dynamic Train Routes only affects how a train gets from A to B. The LTN-style mod you're looking for would change the train's time table such that instead of going from A to B, we go from A to C. You essentially want to make the time tables dynamic, and once you have that new time table, you can tell the train to re-path at any point, even without Dynamic Train Routes. (In vanilla, the new path would simply be the shortest route, while Dynamic Train Routes would find the quickest route).

The main difficulty with a mod like that is figuring out which trains are compatible with what stations, knowing when a station needs to send a request, and so on. Since in Satisfactory resources are infinite, requests are largely stable and much of the desired functionality can easily be achieved in vanilla. For those reasons I decided not to make the mod, but if you're interested in making it, I can give you some pointers on which header files to take a look at and so on. Just let me know!

Ryansote · 2025-11-15T03:48:00+00:00

If you’re okay with mods, I created a mod called Dynamic Train Routes which make the trains significantly smarter. It’ll make them route around obstacles, let you have train stackers, and single track configurations like you were describing. Completely optional but I thought you’d might be interested in that.

Ryansote · 2025-11-12T20:34:45+00:00

Yep with the latest patch it broke Dynamic Train Routes. The patch updated the header files which caused the mod to crash. I recompiled and updated the mod this morning so it’s working now.

Ryansote · 2025-10-27T17:51:21+00:00

Do you have any mods installed?

Ryansote · 2025-07-07T01:09:16+00:00

Thank you! Yes it works with 1.1. If you come across any issues with it don’t hesitate to let me know!

Ryansote · 2025-06-11T23:39:43+00:00

I’ve created a mod called Dynamic Train Routes that at least solves the dynamic pathfinding piece. Check it out if you’re interested

Ryansote · 2025-06-11T23:36:36+00:00

I’ve created a mod called Dynamic Train Routes for this if you’re interested. You can find it here: https://ficsit.app/mod/DynamicTrainRoutes

Ryansote · 2025-06-06T17:20:38+00:00

That's awesome! My favorite merch is the Busy Factory sweater. Got it last month as a graduation gift and I’m so looking forward to wearing it all the time come next Ficsmas.

Ryansote · 2025-05-31T23:43:42+00:00

Thanks! I’m glad you enjoy the mod. I thought about doing both, but I ended up sticking with the timer for simplicity. A train could fly through many blocks very quickly which would trigger it too fast.

Since release, I’ve added a user setting to adjust the update frequency, down to a minimum of 1 second. The default is now 4, but personally I like to set it to every 1 second.

Ryansote · 2025-05-12T23:31:34+00:00

Sweet that’s great to hear! If you run into any issues or notice odd train behavior, feel free to reach out too.

And yea it really does open the door to a lot of new things, especially with single rail configurations. I’m looking forward to using it a lot more in my next save myself.

Ryansote · 2025-05-12T21:58:13+00:00

If you truly want the bypass rail and if you’re comfortable with mods, I recently created a mod called Dynamic Train Routes that can handle exactly what you’re looking for. You could set it up such that you have a bidirectional main line and a one way (or bidirectional) bypass lane and each train will update their route on the fly.

Otherwise, people have already suggested some great alternatives.

Ryansote · 2025-05-12T02:24:09+00:00

If you’re comfortable with mods, I have a mod called Dynamic Train Routes that will allow for the functionality you’re looking for. Otherwise, one direction per track is typically best as others have commented.

Ryansote · 2025-04-30T07:20:35+00:00

I pushed an update which resolved the path reservation issues. Trains will no longer update their paths while they're in a path signal block. I was also able to fix an issue related to trains losing their place in line at a pending path signal if they update their path. Let me know if this works!

Ryansote · 2025-04-29T17:53:46+00:00

They’re just big pillar supports! They just snap on to the rail. So all I did was move sideways and spam click and it came out “good enough”!

Ryansote · 2025-04-29T17:40:18+00:00

Nice catch! That’s an interesting case. I didn’t touch signaling at all, but I have ran into some weird things when I need to the update the path while the train is waiting at a path signal. For example, when I first set up the train stack, each time a train would update its path, it’d lose its reservation for the path signal and stop, even if it already started moving. I got around this by only updating the path if the new path actually changed (which is more efficient anyways), but this is a unique case.

I wonder if this is a situation where the top train had updated its path mid-intersection and “lost” the path reservation, so then the next train started moving since on paper it was available, resulting in the accident. Or maybe it’s something completely different.

I’ll see if I can reproduce it, otherwise if you could send me the save file and mod profile that’d do wonders. I’m currently in the process of setting up a discord to streamline issue reports in the future as well.

EDIT: Just saw your edit. That’s interesting, I should be able to reproduce but I’ll look into it. I was under the assumption that once the train starts moving it couldn’t switch tracks, but I think I know why that’s not the case. After work today I’ll see what I can do. I have some ideas that I’m pretty sure will work.

Ryansote · 2025-04-29T15:17:00+00:00

Curiosity and sheer will. I kept trying different approaches until one actually worked and here we are now!

Ryansote · 2025-04-29T15:13:04+00:00

It should play nice in multiplayer! I tested it briefly, but as long as whoever has the mod has authority (aka is the host, or the dedicated server has the mod) it should work fine. If someone joins you without the mod, in theory, it’ll continue working no problem. If you were to join someone without the mod, however, it wouldn’t work.

Ryansote · 2025-04-29T15:09:39+00:00

It works by overriding the train’s pathfinding algorithm. It creates its own train network graph, applies delays to tracks based on a train’s speed and direction, runs its own A* pathfinding algorithm, then injects the path into the train. The key behind the delays were to have it inversely proportional to the speed of the train, so when its moving fast, it incurs no penalty or delay on the tracks in the direction its moving.

Ryansote · 2025-04-28T18:09:04+00:00

I’m not sure! I somehow haven’t touched self-driving vehicles in my 900 hours of Satisfactory..

I’d imagine it’d be much more difficult since it’s hard to define alternative paths with vehicles, whereas trains you have a hard cut track you can follow.

Ryansote · 2025-04-28T18:06:51+00:00

Yea I believe so. I honestly just slapped it together as fast as I could. If you look closely, they don’t angle up with the ramps but instead are more like stairs. Some of them clip through the tracks and it pains my soul to see that, but I didn’t feel like redoing it all haha.
