[done]Spawning items to the ground every x seconds

Sorry for the bad english but i'm italian
Hi I'm new to lua and factorio modding in general. I have a question for you. I want to make a mod that adds special trees to the game. these trees, will grow and then drop to the ground an item every minute/some time. can someone help me? thanks!

Use the on_tick event to do something every minute. There are 60 ticks per second, so 60*60 = 3600 per minute.

Code: Select all

script.on_event(defines.events.on_tick, function()
  if game.tick % 3600 then
    -- make your trees drop items
  end
end)

To create entities, use create_entity() on the player surface:

Code: Select all

game.players[playerId].surface.create_entity(...)  -- playerId is index of a player

Three good sources of info:

* API docs
* Modding section in the wiki
* Mod portal - download mods that do similar things, unzip them and see how they do it

See also: Modding references, in particular the large guide to modding.
