And if it doesn't, can you think of anyway to have the mod retro-gen (via commands)?
I don't think it should be that much trouble, you can probably take an example at Bob's Ores, he has a command integrated that allows him to retrogen the ores after a map has been created!

I really like the idea and the challenge behind this mod!

Also help with the pollution if you plan your base correctly

You can add this to old maps, and it will start working on new chunks as you generate them.

Retrogen would be very laggy and take a long time, judging by the amount of lag it already adds to the world generation. I'll try it anyways, though.

seronis wrote:Any retroactive forest generation is gonna lock in your base though, so thats not really an issue. And if you want different trees then just do that. Grab a random number in the range of the number of trees and use that to choose a tree for placement.

function generate_trees(event)
  local surface = event.surface
  -- bottom left of the chunk
  minx = event.area.left_top.x
  miny = event.area.left_top.y
  
  -- bottom right of the chunk
  maxx = event.area.right_bottom.x
  maxy = event.area.right_bottom.y

  -- iterate left to right
  for x = minx, maxx do
  
    -- iterate up to down
    for y = miny, maxy do
      
      -- chose random tree type
      tree_type = trees[math.random(1, #trees)]
      
      -- spawn tree
      if surface.can_place_entity{name = tree_type, position = {x, y}} then
        surface.create_entity{name = tree_type, position = {x, y}}
      end
    end
  end
end

• Looking up a variable in a loop instead of storing it in a variable outside a loop is bad for performance
• Ignoring the surface from the event means this will break any games with multiple surfaces

  minx = event.area.left_top.x

      if surface.can_place_entity{name = tree_type, position = {x, y}} then
        surface.create_entity{name = tree_type, position = {x, y}}
      end
    end
  end
end

Just my 2¢

Hardcoding this to game.get_surface(1) is bad for two reasons:

• Looking up a variable in a loop instead of storing it in a variable outside a loop is bad for performance
• Ignoring the surface from the event means this will break any games with multiple surfaces
