Unique Set Piece (solved)

[Minitte]

I am trying to create a set piece that only generates once. Have I have right now generates it correctly but there more than one.

 --import some needed stuff
local Layouts = GLOBAL.require("map/layouts").Layouts --this is where we add the setpiece
local StaticLayout = GLOBAL.require("map/static_layout") --this helps us load the setpiece

Layouts["surface_lightbulb_fissure"] = StaticLayout.Get("map/static_layouts/surface_lightbulb_fissure") --index your setpiece

AddRoomPreInit("Forest", function(room) --"Forest" is the biotope in this case
    if not room.contents.countstaticlayouts then
        room.contents.countstaticlayouts = {}
    end
    room.contents.countstaticlayouts["surface_lightbulb_fissure"] = 1 --add one
end)

The code above is based on the set piece tutorial from http://dontstarveapi.com/tutorials/creating-your-first-mod/setpiece/

Also

I tried looking into how pig king or the lunar island's alter pieces are spawned but I don't really get it. :l

Edit:Nvm it's on the 2nd post for the tutorial forum post.

Solution:

AddLevelPreInitAny(function(level)
	if level.location ~= "forest" then -- only in overworld
		return
	end
	if level.required_setpieces == nil then -- if required_setpieces does not exist already, create it
		level.required_setpieces = {}
	end
	table.insert(level.required_setpieces, "surface_lightbulb_fissure")
end)
