You can filter a traincar's inventory.

(By default), middle-click on a slot, and that slot will now only accept that item type.

I think when the train has decided to go to either station it will go there. Blocking its path with rail signals won't make it change its mind. So the suggested approach with rail signals will not work. Could you work around this by having a staging station? Inline with both stations (with an appro...

This is a weird one. On a machine with Ubuntu 12.04, via steam. The symptom is the window popping up, but containing no content -- just the window decorations surrounding a transparent rectangle. Here's my test case sequence: Start -- fails. Try again twice more -- fails. remove mods -- succeeds. re...

My best shot, given that I'm going to sleep and can't prototype this right now -- constant combinator A outputs 1 <var>, for some <var> of your choice decider combinator B outputs <red circuits> == 0 to <var2> (This could be done with a arithmetic instead) arithmetic combinator C outputs <var> * <va...

I would add that this is a perfect candidate to use the new color signals as well (and possibly others?). That way the player could configure the color of the alert as they think appropriate. Thus, accumulator power dropping to zero could be a red alert, while oil stocks dropping below 80% could be ...

You can add one more to the list of people that understand predicate logic and don't consider it obvious how it works. I now understand, primarily from having looked over the truth tables, but I agree it's not obvious without experimentation. However, since everyone is throwing out how they want con...

It comes from the entity having a buffer of energy available. It's defined by entity.electric_buffer_size . I can't find anything about where it comes from though. For the radar, though, for example, it's 5333.3333... (via game.player.print(game.player.selected.electric_buffer_size). That means that...

In a vaguely parallel manner, an alternative (partial) solution would be to just entirely disable the personal roboport(s). I have had plenty of cases where I would just like to say "under no circumstances should you guys go outside right now" -- often involving biters that can one-shot th...

First, I agree and like the first-upgrade-is-type idea. I would also extend it to say that you cannot place belt while in upgrade mode. That is, if you start by clicking in open area, you're in "[re]place" mode, and can add belts wherever, including replacing existing ones. This is the cur...

... Get a car or tank and slowly damage it from above until it's destroyed. Be careful not to hit the tree. Technically not deconstructing, but hey, it's just a pipe and that tree seems important to you. I like that idea. I would extend it a little bit by suggesting going from the side though. It r...

Given that this is an interaction with the rest of your system, what are you running this on?

Specifically software (operating system and version), but if it's anything weird, the hardware specs would be useful as well.

Err -- if it's possible that setting Factorio to the low-memory setting causes it to run out of memory, that is 100% a bug. It absolutely should not be possible for a setting within the program to cause itself to crash. It basically becomes an undocumented checkbox in the options menu that crashes t...

I had to go install that mod, but I think this will do it H4sIAAAAAAAA/7WW3W6jMBCFXyXyZRcqIMBeVF6pfYytVsgxQzOSsZExbSPEu69N/iAiCXS3l5F9huPPxzPJ1UoozsQqoy1Igwahpm0rWQmUMM6bshHMKE28 StV2VUnaflJ//Zh4O+qnj0nncSUlcLdkla8kJH9oqyG3VfqCuwxzmnZd56nGVI3JanyTTNDW7Cr7jXfUpmGCePtP7hf938QJDjbqkgnhg7Af0cj9Sgm4sJM6 ...

That log is indicating that it's currently set to 4GB -- that should be way more than enough. A few things to try: 1. disable mods. The error appears to be when it's trying to make a 2048x2048 sprite, which is either a clever trick by the devs (and not a problem), or something is making your texture...

Hi, I know about copy paste (shift right but and shift left but), but I do not want to copy 100 times... Is there a way to make a multiple paste ? Just checking, are you asking for <shift-right> <shift-left> <shift-left>..... <shift-left>? So that you don't have to keep doing the copy operation? .....

I don't know of a direct way of doing this, but it should be possible to do indirectly. Specifically, power can be plotted this way. This means you just need to convert accumulator charge into a power output. Here's my proposal: build a sawtooth generator for the range 1-100 -- pick a signal, and th...

As of 0.13 --

>Removed game.get_player() and game.get_surface(): game.players[] and game.surfaces[] can be used instead.

So, `game.players['WIZ4'].force = game.forces['neutral']` is the new replacement.

Why not use the bots to return each other? On your "no-vacation" outer-edge roboports, have an inserter (preferably a regular one) relocate the bots from the roboport into a provider chest. Then, you can have a request chest back in the middle that requests them and then re-injects them in...

I agree that it's due to the fast belt on the load balancer, and that it can be fixed by replacing it with a normal belt, but disagree with the numbers -- Let's try to take a single item out of the output, assuming the system is fully backed up (which appears to be your use case) -- there is a 1/2 c...
