I was wondering if I could build a nuclear reactor that outputs over 1TW (=1000GW) worth of power. So I built one: 1TW.png What is needed? To produce 1TW worth of power, solar panels isn't going to work. It would require ~16.7 million solar cells, which would result in ~146.500 chunks paved with sol...

When trying to place the blueprint below, the center two belt pieces are not drawn, see image. However, they are built when the blueprint is placed, and the belts on the site are curved, which shows that those pieces are there. belt-error.png 0eNqVktFugzAMRf/Fz2EiKXQlv1JVE7TWZAlMlLjVEMq/j8AeupVq9NGJ...

In addition, there appears to be slight discrepancies in the number due to rounding (the real number for one side of the belt is 400 items/min, not 399.60). This is due to us inputting the belt speed with just two decimals places of precision. We should fix that. I believe that this discrepancy is ...

If the terrain imagery is being updated, then it would be nice to have the water turn dark blue/black during the nights, as it is no longer reflecting sunlight. Now the water looks like blue irradiant goo at night.

EDIT: Perhaps this should be taken into account: https://forums.factorio.com/viewtopic.php?f=6&t=47645 cause it is "such a thing that cries for change". :) I've once tried to merge some of the logistics feature requests into a single proposal (https://forums.factorio.com/viewtopic.php...

Ok, thanks!

I was creating a mod that replaces a few fluids with other fluids, so I created the following migration script and saved it as ' migrations/migrate.json '. When I loaded a game, all my raw wood was replaced by advanced circuits, as expected. However all pipes that contained water still contained wat...

For selecting what concrete type the borders should be, I'd suggest always use non-hazard type. The difference is probably barely noticeable, but you will get consistent results, regardless of hazard concrete formation.

Considering the amount of settings that exist now, it might be useful to be able to have presets, so you can pick one that is close to what you want, and don;t have to change much. It is then also useful if you could save your settings as a new preset.

Instead of storing the distance between items, you can store for each item the time/tick when it will reach the end of the segment (if it won't block or be removed). That reminds me of what kovarex initially proposed and we had ton of arguments about it thereafter. The biggest problem - you also ha...

Instead of storing the distance between items, you can store for each item the time/tick when it will reach the end of the segment (if it won't block or be removed). Then segments only need to be updated when items are inserted/removed/side loaded. The distance to the end of the segment, also taking...

My preference goes to image 2. Though it looks wrong because the RGB channels are modified directly. Instead, the nightvision areas should be lighted based on their luminosity . This should then be blended into the unlighted areas. The luminosity can be multiplied by a nightvision_color, to add a gr...

This stack overflow answer was a pretty massive eye opener to me, as far as how much effect the branch predictor can have. For me as well. Though, somehow I don't seem to encounter situations where improving branch prediction makes an important difference. However, dynamic function calls are also b...

I've been having similar problems recently. At 86°C the CPU starts throttling to prevent it from heating up even more. At 103°C the laptop would shut down, keeping only the fans running at max speed, in which case the laptop won't start again until the power-cord and batteries have been removed for ...

This is fantastic! You've just solved a roadblock I was having in one of my mods! Credit will be given! If you have other gems like this floating around, please share! :D What mod are you working on and what problem did you have? Not, per chance, figuring out how to draw the wires/cables for the Ro...

The labels should be fairly easy to create using entities. The arrows can be created using beam entities. Though, unfortunately, there seems to be a bug in the rendering of beams. arrows1.png The mod I used to create this image: lines_0.0.1.zip data.lua: data:extend({ { type = "beam", name...

You cannot mix two types of entities, but you can link them using events. Code would look something like this: script.on_event(defines.events.on_built_entity, function(event) if event.created_entity.name == "my-rail-type" then local entity = event.created_entity local control = entity.surf...

Creating a beam entity with damage_interval=0 causes factorio to crash with a SIGSEGV. Steps to reproduce: 1. Install the attached 'lines' mod. This mod creates a beam entity upon 'on_player_created'. The beam has damage_interval=0. 2. Start factorio. 3. Start a new game. 4. Factorio crashes with a ...

You can possibly use scripting to create an invisible entity that does accept wires (and has no collision) on top of the rails and attach the red/green wires to that entity.

My opinion is that you should be able to request more of an item than is currently available in the network. For example, if there are only 15 cargo wagons in your network, but you need 20, then you can request 20. The first 15 will be delivered as soon as possible, while the remaining 5 cargo wagon...
