At first, I double checked this isn't April's Fools. No, it's Sep 08.

Robots don't do pathfinding, because it's too expensive. And it will almost certainly always be too expensive. Did you know that pathfinding lag is what kills most games of Dwarf Fortress? It is. Pathfinding doesn't have simple, efficient, solutions. Particularly in scenarios where the map can ...

You've already made so many improvements in the cleverness of the behavior of various entities that it might be worth considering adding a "better software" item to the research :D (Seriously, it would feel great to suddenly unlock such improvements after using dumb robots for a while ...

The "solution" for bots running out of fuel and turning back, seems like a good idea when you have it set up as in the example. But if their start point was the nearest roboport to their destination, it wouldn't help.

The construction area should prevent this under all conditions.
If a ...

Finally, I was wondering if it would be possible to use the GPU for robot planning. After all, it's one program running on many data (robots), which is a well parallelizable task.


At first, you could use multiple CPU cores to do so. Factorio runs mostly on a single thread, and parallelling ...

The proposed changes by the devs do solve, like, a lot of the issues, reducing the savings from this approach, but a huge factor is how much it would reduce the visual annoyance and make the robots look smart(er).


I agree with @BicycleEater.
Literally every single statement he said is true ...

1. Did you solve the "over-delivery" problem ?
Example: requester box asks for 2 walls, logi-bot with 4 slot capacity bring 4 walls.
Is it possible trust logi network to a point, when I ask for certain amount, then logi network delivers the exact requested amount?

I solved this issue by using a ...

the bot improvements really look nice, that is nice work there.

I have a question/request to devs though. do not get me wrong, I like the ideas but also I am thinking about my future play because some new features/improvements might require restarting maps (I guess) I have been investing for ...

- Also the repair mechanism for bots isn't the best: Walls get attacked, flame throwers put biters and the walls on fire, bots come in to repair / rebuild walls immediately and die in the fire or to the biters themselves. Maybe you could solve that by not assigning any construction bots to tasks ...

Personally, I always struggle with the following bots' behaviour:

1. Bots returning to recharge

Construction robot has a task that's near the edge of the construction area
Bot flies from afar, losing its charge when near the destination
Bot slowly returns to the dock station, then proceeds to ...

Thanks for the suggestion. I've seen this one before, but it exists only for VSCode which I personally don't like.
However, even Factorio Modding Tool Kit can't export Lua API in external format so other apps can use it.

The Factorio provides documentation for its API in the two formats -- HTML (Web) and JSON.
However, most IDEs require specific format for the built-in functions, and for Lua it's LuaDoc or LDoc (which is newer version of LuaDoc).
I was unable to find any on the Internet, so I've created parser for ...

Great suggestion.
+1 on that

What Happened
I queued a bunch of researches and went to sleep.
On the morning I've found that Factorio crashed (not a map crash with return to the main menu, a complete app crash with core dump).
The game was running without any user interaction.

My PC is configured to not go sleep mode while ...

Factorio Blueprint: Unit Tests Module
I've desigined a number of compact processors from Compact Circuits (https://mods.factorio.com/mod/compaktcircuit) mod to test other Compact Circuits.

It uses 3 separate modules:
