TL;DR Staged blueprints that would place a compatible upgrade of an existing entity should mark that entity for upgrading instead of blocking placement or requiring super force building. What ? It's fairly common to make a series of compatible blueprints that are designed to be stamped on top of on...

Awesome thank you!

Hi! It would be much easier to add screenshots as attachments if the forum supported pasting images from the clipboard. The popular phpBB extension Clipboard Image (23k downloads) claims to add this capability to phpBB forums like this one. The browser feature that enables this is now widely support...

But the one thing I absolutely hate is that it seems like the rail support having a different hitbox depending on whether or not its rotation is directly along the X and Y axis or somewhere in the middle (looking at the picture with the different rotations of the support). Should imho just be a sol...

So who's gonna make the first diverging diamond train crossing?

When you have a large number of ghost items (say to place landfill or concrete) a Spidertron directed by remote with roboports, bots, charge, and inventory in Trunk will only sporadically/inconsistently send construction bots to place items on top of ghosts. "sporadically/inconsistently" m...

Shift+Right Click on one Spidertron then Shift+Left Click on another does not copy Trunk filters, Color, Name, or Auto targeting settings from the first onto the second. I would expect it to do this for Trunk filters because it works for cars, tanks and traincars; as well as color settings because c...

Ah my train stacker is signalled incorrectly. For train stackers you need a single chain signal feeding into a set of normal signals where trains park, and chain signals on exits. I had these backwards.

Edit: jockeril, I just missed your post with mine, but that was it. Thanks!

Maybe I'm confused, but doesn't a chain signal prevent trains from stopping at it? My understanding is that the train has to have an open normal signal ahead for it to actually path through a chain signal. I thought I understood train signals pretty well but this one is baffling me. If I'm just craz...

Yes actually that why I posted this. If they're experimenting with different options, now is probably the best time to present a possible solution.

Edit: Me whinging with no context. Feel free to ignore. So coming back and re-reading this post I realized a couple things. This is literally a data structure/algorithm design document. By the post alone, the best even the devs could say is that it has some neat ideas, but it would need to be implem...

It works fine. As in, it can work just like it does now. But I've also added a fix for multiple fluid types where the type with less fluid is pushed back (see my last FAQ question, if you can make sense of it). Looking closer at your links (very relevant, thank you!), this is more of a very strong o...

I have an idea for a new fluid box update algorithm that I think has some nice properties that could make it faster. In general, I think the current idea of simulating fluids on a per-tile basis can be optimized to the point where it's not a bottleneck and we can fix some quirks along the way. Updat...

You shouldn't be able to put productivity modules into beacons at all.

I just tried in 0.16.21 vanilla, and there is no way to put productivity modules in the beacon.

Are you sure this isn't an issue with a mod you have installed?

Well that's why rendering is using so much memory, silly. One of those textures is huge!

My goal would be to make all smoke immutable . It's current state is directly calculated from starting state and current tick, and only for the rendered region; it's never updated until it's removed. This would turn a read/write loop on the whole map into a read-only loop (+some calculations) in jus...

I've been thinking about smoke. Is there any reason why smoke needs to be ticked at all? Just store a static list of smoke start location (x,y in chunk) and tick number that it was placed there (which could be as low as 4 bytes per entity). All the logic can be in the render function: smoke age = cu...

"Dude, where's my car?" - stootachtig Labels on blueprints? It would be nice to make labels part of a blueprint so that if you constructed many of them they would all be labeled automatically instead of having to be labeled manually. Opacity slider for pollution? I'd like to keep an eye o...

How does this iterative approach handle pathological edge cases?

E.g. two completely separate mazes where at one end tile the first maze is optimal, but only one tile over the other maze is optimal.

So in a pure combinator network (i.e. no smart inserters/chests etc), items are basically symbols that represent processor registers, except they can be local instead of global registers.
