this example is from my library, so has a fair bit of safety adding to it, to make sure other mods didn't outright delete the technology or something.
instead of technology, you'd use... "logistic-robots" or whatever your technology is, and likewise recipe would be "roboport".
The first few lines in this are just to make sure the recipe and technology exist, and if the technology doesn't have an effects table, add it, the final line (before the last end) is the one doing the actual job.

Code: Select all

  if data.raw.technology[technology] and data.raw.recipe[recipe] then
    if not data.raw.technology[technology].effects then
      data.raw.technology[technology].effects = {}
    end
    table.insert(data.raw.technology[technology].effects,{type = "unlock-recipe", recipe = recipe})
  end

To remove is a little harder, since you have to cycle through all the items in the list, then remove the right one.

Code: Select all

  if data.raw.technology[technology] and data.raw.technology[technology].effects then
    for i, effect in pairs(data.raw.technology[technology].effects) do
      if effect.type == "unlock-recipe" and effect.recipe == recipe then
        table.remove(data.raw.technology[technology].effects,i)
      end
    end
  end

again, since this is just from my library, the first line is checking to make sure that the technology exists, and that it has an effects table.
