Squads don't change targets if pathfinding fails #96

ctcarton · 2017-03-10T11:05:56Z

I know factorio pathfinding isn't the most reliable. To compensate for that I would expect the squads to change targets if they can't find a path after some reasonable timeout, but they don't seem to do that. If the nearest alien hive is on an island or some other hard to path location the robots will just sit there forever instead of seeking out the second closest.

Have you tried the "unstable" branch yet? It has some fixes for that. please test it for me :)

I just tried both unstable and development and got this error for both: http://imgur.com/7tw17in

kyranf · 2017-03-29T11:03:20Z

hey i just updated Unstable branch with a possible fix, please try it now. @ctcarton

kyranf · 2017-04-06T22:44:23Z

I fixed another bug I found later while testing, same part of the code.

thisismynombre · 2017-04-11T13:21:23Z

This is still happening, even with code I checked out from the unstable branch two days ago.

I am getting the same crash every time I deploy a robot.

@thisismynombre can you check out the latest unstable branch please and try again? On line 52 of Squad.lua I cannot see any possible situation that the code can fail with a nil table or arithmetic so this is really strange..

thisismynombre · 2017-04-11T14:40:59Z

Same thing, that's with code I downloaded off of the unstable branch just a few minutes ago.

Okay I added a line before that, to try and print out what it has in the table before it gets to line 52 and has the error. It will still have the error, but can you tell me what it says just before the error? It will print a message to the game chat.

kyranf · 2017-04-12T12:59:35Z

@thisismynombre could you maybe upload your saved game as a .zip to here (as an attachment) so I can take a look at it? Can you also confirm that this is a new game, or if it's an old game that you've applied the updated files to?

thisismynombre · 2017-04-12T14:58:01Z

I'll attach the save shortly.

I created it last week, so it's new. However, I haven't tried a new save with each fix if that's what you mean.

I tried the print function above, but it crashed because it was expecting a number in that printf statement. I tried playing with it some, to get it to log or print, but I ran out of time this morning.

thisismynombre · 2017-04-12T15:02:00Z

Here's the save I've been using:

Here's a video of me trying your most recent merge with the print function:

kyranf · 2017-04-12T15:08:12Z

@thisismynombre thanks, i'll load up your save and find out exactly what's going on. It seems like the global table never gets made, or my syntax which is meant to be catching and fixing that is actually causing the problem in the end.

kyranf · 2017-04-12T18:01:02Z

@thisismynombre Okay, I fixed it. I put a check in there to see if the table which was meant to be of "integer" type was actually of "table" type, and deleted/remade the entry as an integer. everything works properly now.

thisismynombre · 2017-04-14T11:29:27Z

That worked, I was able to deploy droids. I had a different crash after a bit, I'll open a new issue with the details.

Thanks for fixing that.

HoGo80 · 2019-02-03T12:37:52Z

Hi, still same problem :(
In case the nearest alien hive is on island for examle, they just stop wandering / attacking and after some time just disappear. The simplest solution may be, if the simply retreat or start to wander, looking for new enemy after each turn.
Btw. nice mod and very clean code with good structure, I liked it :)

kyranf · 2019-02-06T16:41:29Z

@HoGo80
yes there is some AI logic in there to give up trying to attack the ones on island and try to find others but in the end, if they are the ONLY targets in their hunting radius, then they will just keep doing the attempt and fail forever until you fix it.

The game currently deletes units which fail pathfinding, as a CPU saving measure by the developers. but obviously that is bad for my mod's users, because you guys spend a lot of resources on these bots. they aren't free like biters.

The new changes in 0.17 when it comes out will allow me to set all the units to not be deleted by the pathfinder failure, which is great. This will stop some of the issues you have. New control method for flying robots should allow them to path to, and kill, enemies on islands without path finding failure so that will come in 0.17 version of mod as well.

HoGo80 · 2019-02-07T10:28:02Z

@kyranf Great, thank you for fast reply and for effort you are making with this mod :)
