trouble creating new prototypes based on fluids in 0.15

[sparr]

here's my data-updates.lua from 0.13:

Code: Select all

local spill_sizes = {
  small =1,
  medium=2,
  large =3
}

for name, proto in pairs(data.raw.fluid) do
  for sizename, size in pairs(spill_sizes) do
    data:extend(
      {
        {
          type = "decorative",
          name = "chemical-spill-" .. proto.name .. '-' .. sizename,
          flags = {"placeable-neutral", "placeable-off-grid", "not-on-map"},
          icon = "__wreckage-pollution__/graphics/entity/chemical-spill-" .. sizename .. ".png",
          subgroup = "chemical-spill",
          order = "d[chemical-spill]-a[" .. proto.name .. "]-a[" .. sizename .. "]",
          collision_box = {{-size, -size}, {size, size}},
          selection_box = {{-size, -size}, {size, size}},
          selectable_in_game = false,
          render_layer = "decorative",
          pictures =
          {
            {
              filename = "__wreckage-pollution__/graphics/entity/chemical-spill-" .. sizename .. ".png",
              width = size * 64,
              height = size * 64,
              tint = proto.base_color,
            }
          }
        },
      }
    )
  end
end

I updated the decorative type to optimized-decorative to get it to run at all. Now I'm running into a problem when I try to create an entity from a prototype such as chemical-spill-lubricant-large which apparently does not exist. I've re-confirmed that data.raw.fluid["lubricant"] exists, so I should still be creating new prototypes based on it. What else might have changed between 0.13 and 0.15 to break this?

A kind soul on reddit discovered that changing the type from optimized-decorative to simple-entity (or even tree) resolves my problems. I will be inquiring elsewhere about differences between the types, again.
