Hello. Never wrote for Factorio. Could you kick me in a right direction to help me write a script that prints all resistances of all enemy prototypes to the file? Or just how to iterate through all available Prototype/Units?

This can be done in two way:

• Data stage: Create your own mod (containing info.json and data-final-fixes.lua) and run this in data-final-fixes.lua:

  Code: Select all

  local objects = {
  	 "unit",			-- Biters/spitters
  	 "unit-spawner", 	-- Spawners
  	 "turret",			-- Worms
   }
  for p, protos in pairs(objects) do
  	log("Type: "..protos) 
  	for p, proto in pairs(data.raw[protos] do
  		log(string.format("Ty %s:\tResistances: %s", p, serpent.block(proto.resistances))
  	end
  end
  

  Potential drawback: Mods that modify resistances in data-final-fixes.lua after your mod is done could falsify your results.
• Directly in the game (all prototypes are final), you can run the following from the command line/chat console:

  Code: Select all

  /c protos = game.get_filtered_entity_prototypes{{filter = "type", type = { "unit", "unit-spawner", "turret"}}}
  for p, proto in pairs(protos) do 
  	log(string.format("Name: %s (%s)\tResistances: %s", p, proto.type, serpent.block(proto.resistances)))
  end

Instrument mode allows an instrument-after-data.lua that is guaranteed to run last.

There's also --dump-data (see Command line parameters).

Right, that would work. I've never used this mode before, though, so I didn't think of it.

There's also --dump-data (see Command line parameters).

Definitely useful in general, but dumping all of data.raw seems a bit excessive in this particular case where the OP is interested only in one particular property of a subset of the game's prototypes.

I agree it is overkill, but the output will most likely also contain the answers to questions that follow "What are the resistances?" . (Also, it's much faster than loading the game and can easily be generated as part of an automated process.)

Thank you, that helps!
