I'd like to have a way to find only entities marked for upgrades.

Currently to find these entities we have to find all entities then iterate them to filter the ones marked for upgrades:

Code: Select all

      local entities = LuaLogisticsCell.owner.surface.find_entities{area=bounds, force=logsiticNetwork.force}
      for _, e in pairs(entities) do
        if e.to_be_upgraded() then 
          ...
        end
      end

According to Rseding expanding find_entities_filtered to check to_be_upgraded would be faster than type filtering and certainly a lot quicker than lua post filtering.

reading to_be_upgraded would be faster since it's a non-virtual function that just reads a bit mask.

add filter to find_entities_filtered to find only entities with to_be_upgraded = true

add filter to find_entities_filtered to find only entities with to_be_upgraded = true
