This is a continuation of the topic Error updating mod for Factorio 2.0 (continued) viewtopic.php?f=25&t=124422

I posted the updated mod "The Ruins Mod" as a fork The Ruins Mod Updated (Time fork) https://mods.factorio.com/mod/Abandoned ... dated_fork

And I had a small but difficult problem for me.

The gist of it is that for a number of reasons I separated all the ruins from this mod into another submod. And now when I launch this mod without content and submods, an error appears:

Code: Select all


The mod The Ruins Mod Updated (Fork) (1.1.7) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event AbandonedRuins_updated_fork::on_tick (ID 0)
AbandonedRuins_updated_fork/spawning.lua:185: bad argument #1 of 1 to 'random' (interval is empty)
stack traceback:
[C]: in function 'random'
AbandonedRuins_updated_fork/spawning.lua:185: in function 'spawn_random_ruin'
AbandonedRuins_updated_fork/control.lua:58: in function <AbandonedRuins_updated_fork/control.lua:53>

It complains about a specific script:

Code: Select all

spawning.spawn_random_ruin = function(ruins, half_size, center, surface)
  --spawn a random ruin from the list
  spawning.spawn_ruin(ruins[math.random(#ruins)], half_size, center, surface)
end

The reason is that the script is looking for ruins files and can't find them:

I know roughly that I need to write a condition in this script so that it launches if there are ruins files, but I have no idea how to write it....

I can make a hack in the form of empty ruins files. But this is not the best solution...

I will be glad to any help! Thank you!

I am also getting this error, happens by tick 93 of a new world.

Well you can trivially prevent the error with an if:

Code: Select all

spawning.spawn_random_ruin = function(ruins, half_size, center, surface)
  if #ruins > 0 then 
      spawning.spawn_ruin(ruins[math.random(#ruins)], half_size, center, surface)
   end
end

Are the ruins supposed to be empty though? How are you loading the files, and where are they stored?

Thank you very much for the tip.

I am familiar with 'if'. But unfortunately I don't have the brains to build such a construction - 'if #ruins > 0 then'

You can laugh at me...

"The ruihs mod" is quite old. I played with it quite a bit myself and noticed that after a few hours of playing with the basic content of the vanilla game, the "Wow" effect disappears... And further spawning of vanilla entities begins to irritate...

But some modders made submods for it with new content. For example, "The Ruins Mod - Fortress Ruins" https://mods.factorio.com/mod/FortressRuins . And this was already more interesting, since they diversified the game quite well.

That's why I separated the content of the original mod into a separate submod "The Ruins Mod - Base (Temporary)" https://mods.factorio.com/mod/AbandonedRuins-base. So that you could play both with vanilla ruins and without them (if you have more creative submods).

I highly recommend reading section 3 of https://www.lua.org/manual/5.2/, it explains what all those symbols mean.

Thank you! I'll read it. Maybe it will help...
