this view that "I can't play without a wiki" is very common.. in communities of stardew valley, terraria and factorio. maybe other games that i don't know about too.
😓 people just can't relax and enjoy the game any more. they have to do everything most effectively, optimize everything, find every secret, ...
actually there's nothing wrong with optimizing and finding every secret... if you do it by yourself! but if you found every secret by looking it up on the wiki.. what did you accomplish lolol??? do you feel proud of yourself? 🤔
😥 sad when these people blame the developers for this.. like "how am i supposed to know X??". well, usually, just by exploring the world of the game.. then, there are also some things that you just aren't supposed to know!!
i think the game is more immersive if it says "this item makes you more lucky" rather than just "increases luck by 4.3%".
then there's also many youtube videos on "how to start game X the right way". 🥺. this is so sad omg. they are usually geared towards beginners, aand consist of "advice" like "always use X, throw away Y. it's been statistically calculated that using X you will generate 3.9% more profit", "when you reach level X, always choose this perk!!", etc.
another cringe is with fallout.. where people research every choice or even just every dialog option in advance using the wiki, and then make this choice/dialog according to this...
people are just.. totally scared of "failure" (not even failure - just not getting the max possible amount of xp and things like that).

Hey there!
You nominated the games, and you voted for them, and now that the votes have been counted, it's time to see what you thought were the best games in 2022!

That's it! You can also find this list on our wiki at https://www.reddit.com/NintendoSwitch/wiki/bestof/2022
Congratulations to all the winners, and we are open to feedback to make this run smoother in the future.
On a related note, one of the suggestions we have been pondering has been to run a series of posts for Best Games across all years - what categories would you like to see in such a series of posts, whether from the above categories or not?

Like, for example, unload iron and copper at 3:1 ratio.
I read this: https://wiki.factorio.com/Tutorial:Circuit_network_cookbook#Memory_Cell_Design
And, thanks to that, I did learn how to make a memory cell. But I can't figure yet how to "clear" the memory cell (e.g. bring it back to 0).
Thanks!

So I'm trying to use the following console command/code from the wiki on a multiplayer server (hosted on GTXGaming if that's relevant). Space Exploration modded server.
/c local surface=game.player.surface
for key, entity in
pairs(surface.find_entities_filtered({force="enemy"}))
do entity.destroy()
end
source: https://wiki.factorio.com/Console#Kill_all_enemies
But I'm running into several errors, first of all: attempt to index field 'player' a nill value
Some googling led me to this being because 'player' has been replaced by 'character' but if I try to run that command I get the following error:
LuaGameScript doesn't contain key character
So I'm kinda lost on how to proceed :D
Any help greatly appreciated!
PS: to be clear my goal is to destroy all visible biters/bases if the only other option is wiping the entire map I'd prefer peaceful mode.

World of Isandor - Kingdoms is searching for new players to join our very unique one-of-a-kind server that offers a LOT of features.
We are looking for new players to join our world as well as seeking DM's who are player oriented in the terms of providing the individual experience of 1 on 1 sessions with players or small groups. Our players are more keen to 'Events' Rather than 'Quests'. Quests usually involve doing one thing or another to gain or loose something. Events on the other hand are things that happen. Lightning strikes in the rain. Goblins decided to setup a camp or want to trade. Events are open ended and can affect the roleplay in any given direction based on how the players roleplay it.
​
The world starts you out on your own instance of a island you can pick from as it'll be your own island to build structures. Maintain your people and more. Much like a civilization type game. Its low on resources so you'll be sailing with our own ship system to the mainland where all of the other players meet and roleplay. Diplomacy, Trade and more is the goal. Make friends. Enemies and more with player and NPC factions that affect the mainland or your island.
We will be making a trailer very soon to show off some of our features.
You can find our Socials here:

• Our Kingdoms additions which support our Third Part Companion App which interfaces with our neverwinter server.
• Run a shop using our dynamic shop system that is very hands on and unique.
• Factorio style crafting on some crafts. Such as the interactable Blacksmith Forge which you have to maintain the heat of your forge and reach melting points to melt various ores and such down. Pour your metals into steel bins to make ingots.
• Seasons - Winter, Summer, Fall, Spring
• Moon Phases
• Faction Interaction and more.
• There is a TON of features and would love to show them off to you.

I'm about 30 hours into a nullius game (many thanks for the words of encoragement in this post!), and finally have some choices to make about modules. The modules seem to match vanilla's pretty closely: https://wiki.factorio.com/Module#Productivity_module. But, I am struggling a bit to understand when I might use a Yield module where I could instead use a Speed or Haste module (actually deciding between those two is a bit tricky, too). I never made much with modules in the vanilla game, so I'm not really familiar with the reasoning or math here. Using the factory planner is helpful, but always seems to suggest that my best bet is speed modules if I want to use fewer machines overall (which makes sense, but is somewhat counterintuitive with Yield's effect on slow recipes).
Are there any guidelines I could follow about what modules to use when in Nullius?

Is there a complete JSON schema for Factorio blueprints available anywhere? The one on the wiki is outdated and incomplete -- it's missing a bunch of newer fields like snap-to-grid, and doesn't have anything at all about upgrade or deconstruction planners (which can appear within blueprint books).

Factorio could really use a set of scenarios / advanced tutorials / challenges that show how combinators work and what kind of things can be built with them.
I realize this is a pretty daunting. It's basically asking for a crash course in digital electronics. How to build logic gates, latches and clocks, and then how to construct more and more complex (and actually useful) things from them.
It also doesn't help that Factorio has no vanilla means to create abstraction. I feel like the vanilla game could really use a configurable logic block entity that can be used to abstract away the details of things we create with combinators (eg: latches, multiplexers, shift registers).

I recently ran into an issue where I needed to add hysteresis behavior to a power switch in my factory so that I could turn off power-heavy parts when the power grid was suffering. I initially set it up as a simple accumulator > power switch check, then watched in horror as it flipped 30 times a second and destroyed my power availability charts.
After finding this multi-value memory cell design with no documentation online, I reversed it and expanded it to be a little more general for this type of work by adding a timer and making usage a little clearer.
This blueprint book contains two blueprints:

10 second memory latch

This blueprint takes in any values from the input side, snapshots them, and sends the snapshot to the output side for 10 seconds before taking another snapshot. Useful for controlling pumps, switches, or anything else that is connected to a rapidly-changing value.

Automatic Power Switch

Uses a slightly rearranged version of the above to integrate with an accumulator and a power switch so that the power grid availability will be sampled every 10 seconds and toggle the power switch when the accumulator power drops below 70% by default. This can be adjusted by just changing the value on the power switch itself.
If you want to adjust the timer on both blueprints, find the decider combinator by the substation that lists A < 600. Modify it to whatever your new value should be (number of seconds * 60). Then adjust the decider combinator near it (the only decider combinator that outputs the information signal) to be your number - 20. For example, to set it to five seconds instead of ten, your first value would be 300 and the second value would be 280.
I hope this is as helpful to you as it is to me!

The base game has one here: https://wiki.factorio.com/Data.raw
I want to cheat in some items for testing without having to resort to a creative mod or the clunky editor (as I need a bunch).

Technical question

I'm pretty sure this is NP-hard, but does anyone have any thoughts on how to find the mutually cheapest path from two (or more) sources to their specific targets - s¹ to t¹ and s² to t² (etc up to n) where a given node can only be on one path.
I originally was looking at stuff like A, but now I think that the problem generalizes to the minimum cost flow problem, with every edge has a capacity of 1 (and varying costs b/c of game details). I think I can set up the problem by creating one source *s⁰ with edges to each sⁱ and one target t⁰ with edges from each tⁱ, and looking to find a flow of n from s⁰ to t⁰. Does this make sense?
Which algorithm would be best for this problem? I don't really know which algorithm is most efficient for this problem in general (https://en.wikipedia.org/wiki/Network_simplex_algorithm?), and I know my specific use case would have massively more nodes and edges than in the solution. Would that mean that a different minimum flow algorithm or pathfinding algorithm is better?
Because of game details, some nodes change in circumstances (see the

Factorio details

Factorio is a game on a cartesian coordinate grid. It uses conveyor belts to move items from place to place, in any of four directions. These conveyor belts take up space, and two conveyor belts can't sit in the same spot. Factorio has undergound belts, that attach to conveyor belts and travel below the ground for up to a certain distance in a straight line. Underground belts are more expensive (and look less nice), so we try to avoid them when possible (but only if it's not better than normal belts).
Normal belt (S=source, B=belt, U=underground belt start/end, T=target, W=wall or obstruction):

.SBBBB.. .....B.. .....B.. .....BT. 

Underground belt

.SBU.WUB.. .....WBB. .....WB.. ... .WBT. 

I think this can be graph G=(V,E) where each node is a coordinate on the graph that doesn't already have a building in it, and each node has edges that can be reached by a single belt or underground belt. One complication is that an underground belt can't turn on the same tile it comes out - it has to continue forward for at least one tile. I think this could be incorporated into the graph, but I'm not sure how.
The mod BeltRouter (https://mods.factorio.com/mod/BeltRouter) will automatically route conveyor belts for you, using the shortest path. It even allows you to do multiple belts at once! However, it does these one at a time, so the first path can get in the way of the second path. I'm looking for ideas on how to solve this.
Thank you! Happy to clarify anything, I appreciate any insight into this.
As a side note, does anyone know of an easy way to visualize shortest path algorithms that lets you use a custom algorithm, preferably in Python?
