Snippet: Count total children of a parent

MikeHart

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))
