This is a bunch of reflexions on what could be done for better fluids/heat in Factorio. Some aspects are really similar to a post of Rseding91 I found recently and can't find again. The context: Fluids in Factorio (that's liquids, gas and heat in heat pipes) are currently simulated through a local f...

That way chunks could align with pages. Per chunk processing would then be able to take advantage of more locality, at least down to L3 or L2 cache. But pages don't matter much, comparatively. Hitting different pages only hit the TLB, which has a cost but not as high as the cache one. Cachelines ma...

I may be wrong, but based on the FFF it appears that you have three different processes that update a single variable, but that variable is shared between each. (...) I also suspect that this isn't the correct path for parallelization any way, you'll likely find that each step itself could be paral...

In the round-about example you gave the train is currently inside a chain signal block and is not allowed to re-path. That was fixed a while ago so it doesn't happen unless you break its path by removing rails/signals/stops. Is switching a stop on/off through the circuit network equivalent to remov...

Of course since you're C++ based... really you'd have to either break the constructor out to an initilaizer instead... or do a new override that takes a set. (C++ Sucks for custom allocations :) ) With modern C++ argpack forwarding and placement new works well to do syntaxes that are both sane and ...

Part of the issue with electrified rail comes in with the problem of "Multiple rail types" As someone, Rseding most likely, previously pointed out... Part of the reason why electrified rail will never happen is down to the whole issue of whether or not a train should be allowed to travel ...

Things like a locomotive don't support other energy source types because electric makes no sense for a moving entity - it would be insanely expensive if they had to re-connect to electric poles every time a locomotive moved. You could have "electrified rail" which connect to a power sourc...

Sharing and the whole invalidation protocol (MESI, MESIF, etc) is done at the cacheline level, not at the page level. That makes the granularity 64 bytes, not 4K. From the previous FFF I gather that not many structures are less than 64 bytes, so I doubt there's a sharing issue in practice. There's p...

the devs should really consider open sourcing the code. Heck No. If you're interested in working on the code, reach out to the devs and ask for a Job, You can sign an NDA and I'm sure the'd love to have you, but open sourcing the code is business suicide. Although I'd never try to tell anyone to op...

Hi Rseding, thank you for the reply. I have just copied the lua files into a directory in the mods folder and that is where i have edited the files. The thought has just occurred to me... I know factorio is reading my lua files and the json but is there anything I need to do to 'enable' my mod, I'v...

I suspect concrete has so much success *because* it has the grid pattern. It's very useful when you want to analyse what's going on. And being under the entities rather than over them it doesn't feel in the way like a superposed grid does.

OG.

This calculates the distance to the entity position, not to the entity bounding box which is a problem because the game uses the bounding box to calculate whether the player is in range to build something. While it is possible to make a function that does calculate the distance to the bounding box,...

i am just wondering, cause dragging works pretty well with anything else. from copying filter settings of filter inserters (like in the screenshot example) to copying production of assemblers and also blueprint modification. so i thought it would be possible to transfer it also to the inventory han...

There's an item specifically designed for this - the "selection-tool" type item. It's what blueprints and the deconstruction planner use. It has nothing to do with custom-inputs - it's tied to a specific item. Hmm yeah, I don't think it matches the use case I have in mind. Let me explain....

Interesting. I'd have chosen a slightly different setup: you have all tech, but a completly empty inventory. How fast can you start and ramp up production?

I'd like to have the capability to add custom-inputs where it's possible to activate the input in one place and move the mouse/move the player so that it applies to multiple tiles/entities/ghosts. Exactly the way the mouse controls currently work for building, filling, destroying, etc. The obvious i...

I mean that the normal mouseclick is draggable while ctrl+lmb is probably not? And i don't know how autofill does it because i've actually never used it ;P. Ctrl-LMB is also used in vanilla to fill/empty entities (with ammo, coal, modules, etc), which is definitely draggable. Technically, it's not ...

I'm not sure how modifier keys like ctrl interact with custom hotkey events. You'll have to look at autofill for that. (report back tho, kinda interested :P). Not sure what you mean. At least I can tell you that key_sequence = "CONTROL + mouse-button-1" works as I expected it, and in part...

Are you allowed to use them to make things like out-of-game blueprint renderers/editors?
