Spawning entities in biter bases on chunk-creation

[Pandemoneus]

I have a mod idea that spawns so-called biter spires which provide free energy. I got this part done. The next step would be to make these entities spawn in biter bases on chunk-creation (I don't want more to spawn when the biters expand). However, I have no idea how to do that. As far as I can see it is related to autoplacing, but I have no idea how to do that in corellation with biter bases. Does anyone have an idea?

Sorry, but that was not helpful. I have looked through the API myself, that doesn't tell me how I can hook into the biter bases autoplacement.

On the chunk generated, find all the biter bases in that newly generated chunk, and then spawn your entity in top of them, something like this:

Code: Select all

script.on_event(defines.events.on_chunk_generated, function(event)
  local area = event.area
  local surface = event.surface
  for k, base in pairs (surface.find_entities_filtered{area = area, type = "unit-spawner"}) do
    surface.create_entity{name = "your-entity", position = base.position, force = base.force}
  end
end)

    surface.create_entity{name = "your-entity", position = base.position, force = base.force}
  end
end)

Thanks, but currently there is no way to do it directly together with the biter base autoplacement, right? I thought it would be possible to modify or add to that.

No way currently, the game won't spawn entities which collide with one another in any case
