Hi everyone,

I'm currently trying to build an auto-splitter for factorio (LiveSplit).

I started from the work done by aureianimus and MrHug (https://github.com/aureianimus/LiveSplit.Factorio) and made my own fork (https://github.com/Tignass/LiveSplit.Factorio/tree/patch-1).

With the help of the cheat file from Bloodybone, I managed to create a script which can autosplit on all the researches (needed for any% speedrun, for now), and building counts. In addition it was made so the modification are easy to make even for a non develloper.

As I'm no speed-runner, I used the tutorial of OverCraft (https://www.speedrun.com/factorio/guide/cl454) to beta test. Is this really used?

I'm posting here to ask you what should be the splits.

Hi Tignass, thank you for looking into this. A auto-splitter for factorio would be wonderful.

I'm posting here to ask you what should be the splits.

Splits are for the moment very individual in that every runner has their own splits. Off the top of my head there are 4 different events used for splits:

• Entity placed (power, lab, locomotive, silo)
• research finished (steelaxe, bots, silo)
• (first) product finished (science, bots)
• the 'game finished' message at the end

An other thing that we have to do manually is start the timer at the first frame. It would be very pleasant if the auto-splitter could do that for us :)

Edit: For the 100% category there are splits at certain achievements.

Thank you for your answer :)

Currently the timer starts automatically with the game (and resets when quitting, this can be disabled via GUI).

I noticed splits are very individual, that's kinda my point in doing this. I'd like to offer a sort of "frame" so speed-runners can compare and improve more easily (even if the main goal would still be launching the rocket). And as I have no legitimacy to decide for the speed-runners, I'm asking them (and you) to discuss the best split list to use (I may create a discord if people are interested).

• it can split on a combination of building "count": For example now there is one, "Burner City", splitting when there is 22 stone-furnace + 35 burner-mining-drill and iron-chest (the others can be found in the "ReadMe" on GitHub) .
• It can split on any research (needed for any%).
• It also split when the end window appear (when the rocket is launched).
• It can't yet split on achievements but, should be possible if requested.
• It can't yet split on "first produced", I tried but couldn't figure it out. If requested I could give it another try (but we can easily do first build ^^).

Additionally, even if a consensus isn't found, everyone can easily modify the settings to set it's own splits: there is 2 ways to configure it, firstly through the LiveSplit GUI and in the text file (Factorio.asl), there is an example and some comments to help modifying the number of buildings on different splits. Here also, if requested I could make a guide on How to modify it.

Wow this sounds cool.

Splitting on research is pretty cool, coupled with when rocket is launched/victory screen, covers Any% quite nicely and might force me to use use more 'conventional' splits.

If you have a version that supports this ready I'd be happy to take on a few test runs to see how it handles it :)

Sounds pretty cool. It's still hard to detect stuff like blue science which is mostly assemblers, when you improvised a bit and added another one previously the condition is like 144 assemblers or something wierd. Is there a chance you can detect something like "12asm that have set the blue science receipt" ? At this point is would be really useful.

@Cobai: Yes my version is ready for what you're asking for (https://github.com/Tignass/LiveSplit.Factorio/tree/patch-1)

@AntiElitz: I'll check if this is possible, according to lua documentation it seems possible but I'm not sure it's saved directly in the memory (which is read by LiveSplit), for example when I looked into "production splits", I could find it but only if you open the stat page in-game, few seconds after you close it, the memory is allocated to something else... But for now you can split on the number of buildings, for now blue science I set (some are deactivated as the number of electric pole might differ one run to another): "stone-furnace", 103 "burner-mining-drill", 37 "iron-chest", 37 "offshore-pump", 3 "boiler", 37 "steam-engine", 74 "electric-mining-drill", 312 "small-electric-pole", 449 "lab", 36 "pipe", 185 "pipe-to-ground", 71 "assembling-machine-1", 26 "express-inserter", 683 "express-belt", 2600 "express-splitter", 8 "long-handed-inserter", 283 "fast-inserter", 131 "underground-belt", 63 "assembling-machine-2", 133 "steel-furnace", 216 "pumpjack", 5 "oil-refinery", 9 "chemical-plant", 8 "storage-tank", 10

I know this was 2 years ago but maybe you could add something with the mod milestones for splits for sciences and such?

Nice

@cowardlycamper32 That would be possible, but the rules don't allow any mods to be used for the speedrun submission to be valid

It's not unheard of for games to have a particular mod that is allowed/blessed by that game's speedrunning community for use in official attempts. We could make a mod that just tracks and publishes an api for production statistics that can be used by an external livesplit program could be implemented with no UI and would have no effect on the gameplay. Something like this seems reasonable at least. Has the factorio speedrunning community ever considered this?

currently its not allowed - for the community to allow it, a suitable mod must exist before we can decide if we want to use it

iirc in the past the issue was that a potential mod had to be updated with every version to work again
