The GUI electricity bar oddness is not a big deal so I'm prepared for it to be not-a-bug, but from the Lua API perspective having LuaEntity .energy == .electric_buffer_size for a lamp with zero electricity available, and no internal generation capacity, is confusing.

Is there a better way than .energy > 0 to consistently detect when entities have power?

I don't know if it better, but I'm using here reading in power poles:

Code: Select all

function get_total_output_energy (output_counts)
  if output_counts then
    local energy = 0
    for input, value in pairs (output_counts) do
      energy = energy + value
    end
    return energy
  end
  return false
end

If it changes between ticks then you have power source, else no power was created.
