How to get number of objects/shapes in scene?

[badfitz66]

I am editing a code, with two shapes in the scene (the circle and the ground), they're each in a table

is there a way I can get the amount of objects inside the table?

Lua tables have a length operator: http://www.lua.org/manual/5.1/manual.html#2.5.5

Code: Select all

#table

If you have simply an array table, you can just use:

Code: Select all

amount = #myTable

But if you have a table with multiple different items in it (for example "table.x", "table['n']" and others), you can use this function I made (which is quite simple, so someone else probably already made it before):

Code: Select all

amount = table.size(myTable)

Code: Select all

function table.size(t)
   local s = 0
   for i, v in pairs(t) do
      s = s + 1
   end
   return s
end
