Including new recipe on vanilla tech when it's already researched

[Chess]

I'm creating a mod with a new combinator that interacts with trains and I'd like to unlock it with the vanilla "circuit-network" technology. This is how I do it:

technology.lua

Code: Select all

table.insert(data.raw["technology"]["circuit-network"].effects, {type = "unlock-recipe",recipe = "train-requests-reader"})

But it doesn't work in saves that already researched that technology. How can I fix that?

Thank you.

If your mod was added to an existing game, script.on_init will be triggered for your mod. Just add this to your event handler:

Code: Select all

for _, force in pairs(game.forces) do
  force.reset_technology_effects()
end

It worked, thank you!
