DaveMcW made a nice tech tree visualization you can start with: http://davemcw.com/factorio/tech-tree/ I was not able to find an image with the entire 0.15 technology tree. It is possible to automate making the thing; the raw data can be found in the game's folder under data\base\prototypes\technolo...

Could try deleting things (make a copy of your save first) until you figure it out: /c for key, entity in pairs(game.player.surface.find_entities_filtered({force=game.player.force, name="roboport"})) do entity.destroy() end /c for key, entity in pairs(game.player.surface.find_entities_filt...

I haven't bothered looking for a mod like this. But this type of mod is theoretically possible (please note that I'm not volunteering to actually write the mod.). Try pasting some of these commands in game. Initialization: /c follow = game.player webcam = game.player.gui.left.add{type="camera&q...

Personally, I'd prefer interrupting the user. Buffering user input & stalling on a single tick for a half second would be less noticeable than the current state of affairs.

Can't the game serialize the non-changing stuff (dirty flags) while the main thread's waiting for the next update tick?

Short of optimizing the save process by concurrently* serializing the non-changing stuff before pausing the game and bringing it into a consistent state, it would be nice if the game buffered the player's inputs while the game is paused, and replayed them after its unpaused. * or doing it during the...

Apparently, it's https://github.com/openunix/cygwin/blob ... in/fork.cc

Another idea, (instead of mmap()/VirtualProtect() shenanigans) is to implement this concurrent algorithm for saving in the background. It's based on the concurrent mark & sweep algorithm sometimes used by the JVM garbage collector, used to minimize stop-the-world pauses. 1) Main thread decides i...

Can't just have it play that error sound when a blueprint can't be mirrored?

And even if all that is not prohibitive I believe windows doesn't have a fork() equivalent at all. That is the main problem. Windows has a VirtualProtect() API that allows you to mark pages as copy on write (PAGE_WRITECOPY). I've used it before. Works nice; certainly a lot faster than fork() which ...

Could the player's starting position just be randomly (but still deterministic) re-positioned, until you're not on a small island? Small islands can be checked by scanning 100 tiles in each cardinal direction, counting the number of land tiles till' ya hit water, adding them up and seeing if the res...

I think that using virtual memory's copy on write functionality within the same process is a better approach, it has less overhead, plus both Linux & Windows have APIs to manipulate the virtual memory protection flags within your own process (mmap/VirtualProtect). Implementing this copy on write...

I did some digging on how to actually implement this idea on Windows & Linux. The basic idea is to create and use a memory mapped file region to contain the current game's state. When it comes time to make a save, change the memory mapping to copy-on-write and then create another view of the sam...

Its probably never going to happen, storing data outside of the game state is a sure fire way to cause a desync What is described here cries for a GUI or remote call. That is the right way to change things over all instances. Cause then the developer will handle the changes correctly. Which is not ...

Even as a new player I've wondered why I couldn't fast-replace a small power pole with a medium one.

This thread suggests 'cycles completed'.

Instead of a confirmation dialog, I'd suggest making it so that if you have a blueprint in hand and you click the trash can, it deletes the blue print. As for when you delete the blueprint book, I'd suggest an undo button (like GitHub's delete pull request button), or altering the trash can icon to ...

I wouldn't implement this. On Windows, allocating large pages requires the SeLockMemoryPrivilege token ( MSDN ), which requires that Factorio be installed with an administrator account, creating a user account on the system, and adding that user account to the "Lock pages in memory" privil...

I ran optipng, a program that tries out lots of different lossless compression algorithms. And it made the graphics folder a whopping 0.2% smaller. 124652 KiB - original 124636 KiB - no bit depth, palette, or color reductions (16 KiB saved) 124400 KiB - w/ reductions (252 KiB) // C# // script takes ...

I'm happy to hear that.

TL;DR As a new, casual, player, I'd enjoy having a few more scenarios in the base campaign. It feels like the campaign is incomplete. What ? There could be more to the storyline after making the plane and flying off in it. A lot more can be done with the aliens, rockets, colony ships, etc. Not to m...
