Alright, so I've scoured everywhere searching for an answer, as well as tried some things on my own, but nothing seems to work properly.

Is there a way to make the ore deposits that are already in the base game drop an item other than the original iron/copper ores?

Yes, just change 'result' property of a resource prototype:

Code: Select all

data:extend{
  {
    type = "resource",
    name = 'copper-ore',
    icon = "__base__/graphics/icons/copper-ore.png",
    flags = {"placeable-neutral"},
    order="a-b-a",
    minable =
    {
      hardness = 0.9,
      mining_particle = "copper-ore-particle",
      mining_time = 2,
      result = 'copper-ore'  <---------------------- THIS
    },
    collision_box = {{ -0.1, -0.1}, {0.1, 0.1}},
    selection_box = {{ -0.5, -0.5}, {0.5, 0.5}},
    autoplace = autoplace_settings('copper-ore', 0.02),
    stage_counts = {1000, 600, 400, 200, 100, 50, 20, 1},
    stages =
    {
      sheet =
      {
        filename = "__base__/graphics/entity/copper-ore/copper-ore.png",
        priority = "extra-high",
        width = 38,
        height = 38,
        frame_count = 4,
        variation_count = 8
      }
    },
    map_color = {r=0.803, g=0.388, b=0.215}
  }
}

Alright, so that worked... sort of. I just straight copied and pasted that into my code, and then changed the result to "iron-ore" just for testing. When I ran factorio, I got the error that calling autoplace_settings was a nil value (or something similar) so I added the autoplace_settings from the demo-recipies prototype in the entities. Now my code is this:

Code: Select all

local function autoplace_settings(name, coverage)
  local ret = {
    control = name,
    sharpness = 1,
    richness_multiplier = 1500,
    richness_multiplier_distance_bonus = 20,
    richness_base = 500,
    coverage = coverage,
    peaks = {
      {
        noise_layer = name,
        noise_octaves_difference = -1.5,
        noise_persistence = 0.3,
      },
    }
  }
end

  data:extend{
  {
    type = "resource",
    name = 'copper-ore',
    icon = "__base__/graphics/icons/copper-ore.png",
    flags = {"placeable-neutral"},
    order="a-b-a",
    minable =
    {
      hardness = 0.9,
      mining_particle = "copper-ore-particle",
      mining_time = 2,
      result = 'iron-ore'  --<---------------------- THIS
    },
    collision_box = {{ -0.1, -0.1}, {0.1, 0.1}},
    selection_box = {{ -0.5, -0.5}, {0.5, 0.5}},
    autoplace = autoplace_settings('copper-ore', 0.02),
    stage_counts = {1000, 600, 400, 200, 100, 50, 20, 1},
    stages =
    {
      sheet =
      {
        filename = "__base__/graphics/entity/copper-ore/copper-ore.png",
        priority = "extra-high",
        width = 38,
        height = 38,
        frame_count = 4,
        variation_count = 8
      }
    },
    map_color = {r=0.803, g=0.388, b=0.215}
  }
}

Now copper ore deposits from my old saves give iron ore. However, copper ore deposits aren't showing up on new worlds at all.

Nevermind, I realized I hadn't copied the whole autoplace_settings function. Works perfectly now, thank you!

Instead of duplicating all of that code you could just leave the existing prototype definition as it is and only change the one thing you care about.

Code: Select all

data.raw.resource["copper-ore"].minable.result = "iron-ore"
