    Hi folks,

    as I converting a game to gideros, I need to know how many children a parent has, including the children of a the children.

    I came up with this function
    local getTotalChildNum = nil
getTotalChildNum = function(parent)
	local nc = 0
	for index = 1,parent:getNumChildren() do
		nc = nc + 1
		local child = parent:getChildAt(index)
		nc = nc + getTotalChildNum(child)
	end
	return nc
end
    To use it, just call it like this:
    print ("Total children in stage: ".. getTotalChildNum(stage))
