Hi,

How would i add a resistance to very entity in the game?

How do I finish the code below?

	local function add_immunity(entities)
	  if not entities.resistances then entities.resistances = {} end
	  table.insert(entities.resistances, {type = "fire", percent = 25})
	  end

	for _,entities in pairs(data.raw[?]) do
		add_immunity(entities)
	end

end

Would I have to call out every entity type?
Thanks

All entity types

Or the ingame source LuaGameScript.entity_prototypes.

(Which is about the control stage, and not the data stage. Also, looping through all of that just for the types seems more tedious than just looking at the wiki.)

Yea. But the control stage "knows" more about the internal layout of the game. So it's easy to extract static info out of it like the types, which do not change. And the wiki does not offer a copy/pastable lua table, which is easy to generate in control stage. In any case OP will have to manually edit the list, because stuff like flying-text, item-entity, or legacy-decorative probably don't do resistances. :=)

What will happen in an entity has the same resistance twice, may or may not be the same amount.
Does it get added together?

In the example below. What will the pole end up with for "poison"? 100, -25 or 75

data.raw["electric-pole"]["small-electric-pole"].resistances[1].type = "poison"
data.raw["electric-pole"]["small-electric-pole"].resistances[1].percent = 100
data.raw["electric-pole"]["small-electric-pole"].resistances[2].type = "poison"
data.raw["electric-pole"]["small-electric-pole"].resistances[2].percent = -25

Thanks.
