Sorry, another question, is there a reason why the server/client must have the exact same data and CRCs?


Once you have deterministic lockstep, the entire game can be simulated perfectly, without errors, and any remaining errors are due to existing errors in data or data corruption, and any ...

Sorry, another question, is there a reason why the server/client must have the exact same data and CRCs?

I see, now that makes sense. Thank you for this info.

I do not know if this is the right location, but I am curious why Factorio uses a deterministic lockstep setup. Was there not any other alternative, or is it due to how the engine handles everything?

I have encountered a very strange bug. My client loads my fixed mod just fine, but my server crashes with the exact mod with this error: 34.479 Error ServerMultiplayerManager.cpp:84: MultiplayerManager failed: "__OreRecipes__/control.lua:13: unexpected symbol near ')'" They are both exactly the same ...

sorry, one more thing: the free-space-science is also very unintelligble for me:

data.raw["assembling-machine"]["assembling-machine-3"].ingredient_count = 10
data.raw["item"]["low-density-structure"].stack_size = 50
data.raw["item"]["rocket-control-unit"].stack_size = 50
data.raw["item"]["rocket ...

Truth is: I have a serious case of dyslexia, so learning code is utterly impossible. I really need people to guide me through these more complex issues with porting the code. I actually have been getting paranoid and now feel that the lua engine is reporting false-positives now.

This is another modifier I am having an issue with, I believe it is a false-positive from the engine itself as these values do not even exist in the code:

Failed to load mods: Error while loading item prototype "burner-fuel-bonus-stone-furnace" (item): Unknown flag "hidden"
Modifications: Burner ...

You need to correct the syntax errors. There are missing "=".

Using an editor such as vscode with its lua plugin helps with writing code that doesn't contain such errors in the first place, since it reports any such error while you type.


I use notepad++ for my editor/debugger. I really wish ...

Can anyone please help me here? I am trying to interpret the factorio API wiki, but I cannot.

This is the error I am getting with void fuel: Failed to load mods:

I try solving complex logistical puzzles with you spare computer hardware or vintage video game collection to optimise the best solution.

I have 1 part schizophrenia, 2 part autism and this game is most certainly attractive to me. I love solving logistical puzzles an creating complex ingredients from the most basic ones. during the 90's however, I was more of an hardcore arcade game player as I had arcade-style games for my Sega ...

Is https://mods.factorio.com/mod/FreeScience the mod you're trying to port? If yes, I think you don't need to change the code that much. It should be enough to change the "result = science.name" line to be "results = {{type = "item", name = science.name, amount = 1}}".


The problem is that upon ...

I am trying to port the void fuel, free science and free space science modifiers to 2.0 and am struggling with them. The science pack ones are spitting out Failed to load mods: Error in assignID: item with name 'science-pack' does not exist. I will update with the void fuel issues later on. This is ...

I have not purchased the expansion just yet due to watching streamers playthroughs as I want to see what I am getting into. Never, in my life of the 40 years of being alive, have I seen an expansion that gives 5x-10x more game-play value than the base game. Imaging if MMOs companies did that? You ...

If the entire 64-bit pool was utilised, it would require super-computer level memory space. All my stacks at 2 billion eat up about 10 GB of memory space, but 64-bit integers are 1.8 duodecillion. No possible home machine can even begin to have that kind of memory capacity (~1-4 exabytes ...

I just want to weigh i non this, and I fully support this pricing. I bought a game back in Janurary for 75 CAD on steam, and it is so broken and buggy that it should not have been sold for that insane price (Cities Skylines II). At least this game worked 100% with full modding out of the box since ...

A former friend gifted it to me on Steam randomly and said "let's play together".

The biggest thing is actually to do with FFF 402 and compressing my data streams to only 1 signal so it will not interfere with other information in the data stream, this issue also arises however when wanting to store a particularly large value.


I'd recommend using a mod that adds more ...
