There's a bunch of typos "engin" "engines", you're copying the entity twice instead if the item and the entity, the last one "steament" doesn't use the table.copy function at all. and a bunch of parameters that don't apply to the respective item/recipe/entity. Please go...

Yeah, the second one. That should get you close enough to start seeing results in the game!

1. You still need all the code you already had, which was correct. steamrecipe should stay the same, and you add a new section for e.g. steamentity 2. What I wrote was correct. Items are stored in data.raw.item, but entities are stored in many different categories, like data.raw.armor and data.raw[&...

The entity for the steam engine is stored in `data.raw.generator["steam-engine"]` and the prototype parameters for the generator entity can be found in the documentation at https://lua-api.factorio.com/latest/prototypes/GeneratorPrototype.html Do another copy.deepcopy of the entity entry, ...

Then I guess what's the actual problem? If the built-in timer priority (Fifo) isn't good enough, use the circuit priority to override it however you like. As long as you arrange it so trains empty completely at each requester, you don't need a separate network for each resource.

"Always have enough" isn't the only answer. You can also let the belts back up until materials reach everywhere and the output runs again. But that can take a while and result in cyclic operation. How about making the LTN station priority dynamically controlled by a timer, so that stations...

Items are only the things held in inventory. Right now your new item places the same old engine entity. You need to make a new Entity and change the placement links for it to be different when you place it.

To clarify, are you trying to solve a particular factory production problem, or are you trying to specifically make trains drive in a specific way? LTN is supposed to operate so that consumers only initiate a request when they have space to completely unload the train before it returns to the depot....

There are a bunch of ways to preempt or diasble pipetting, both via prototype flags and via scripts. Look at some of my mods for ways to do it! They also handle blueprintable/not blueprintable items. https://mods.factorio.com/mod/MultipleUnitTrainControl (change MU setting to "Basic", put ...

Make a table with strings as keys and numbers as values, then index it with the string value of the setting to get the corresponding number.

Mapping = {one=1,["number two"]=2}

Mapping["one"] == 1

Note that some benchmarkers have found the Vcache on the X3D chips doesn't help Factorio performance much if the map is too big for the important bits to fit in the cache. At that point the bottleneck is raw latency to the DDR memory same as a normal processor.

It doesn't match the error given, but the code you ran won't work anyways. On_load is only allowed to read variables, not alter the game state by creating entities. On_load runs when you load a savegame, and the simulation is supposed to be unaware of whether it has been saved and loaded or just kep...

Wow, even putting it in quotes doesn't help. +1

In FFF 391 they at least show 2.0 will add access to the mod manager if there is a mod loading error. It would be great if there were a shortcut to invoke this before loading at all. https://www.factorio.com/blog/post/fff-391

About the problem on how to refuel a stuck train on a water-bridge... Why not just giving bridges emergency-solar-panels which allow them to power trains so they can drive at 5 km/h maximum speed while on the bridge until they are on solid ground again? Almost nobody talks about the ability to coup...

[ I'm also quite curious how the "light speed crafting" was implemented. As I've thought about the issue of crafting more than one item per tick before. And my thoughts were to just use 2 fixed point integers. One for the crafting progress per tick, and the other being the current progres...

It may even be possible to use a Lua combinator mod like https://mods.factorio.com/mod/Moon_Logic to call https://lua-api.factorio.com/latest/classes/LuaGameScript.html#write_file to log circuit values, at least as a prototype. Qon's idea 9f having tagged value logger combinators so everything ends ...

I am currently running a rather large space exploration world so it has become almost impossible to manage supply and demand of all my intermediate products. Trying to use the production/consumption statistics isn't that useful as consumption will almost always match production when in steady state...

This is an interesting topic. I'm not totally clear what all the data you are looking for is. Are you trying to log data over time while running a map in the game, so you can plot it afterwards? Can you list what exactly you are trying to log, so we can identify sources for each piece? Some of the d...
