If yes then:

Code: Select all

songMusic:setLooping( false )

1. you are comparing it to values, instead of indexes.
2. you only have string keys, which means #t is always 0.

write_table = function (t)
   local s = "{"
   local first = true
   for k,v in pairs(t) do
      if first then
          first = false
      else
          s = s .. ", "
      end
      s = s .. k .. " = " .. v
   end
   s = s .. "}"
   return s
end

Using #t doesn't work here because

This is a better solution if you really don't want terminating commas:

Code: Select all

write_table = function (t)
   local s = "{"
   local first = true
   for k,v in pairs(t) do
      if first then
          first = false
      else
          s = s .. ", "
      end
      s = s .. k .. " = " .. v
   end
   s = s .. "}"
   return s
end

Then call print(write_table({a=1, b=2, c=3})), it should print {a=1, b=2, c=3}.

The order is arbitrary, that is because it is a hash table, which means keys are no stored in any order you would expect, but instead stored in a way that makes it fast to retrieve items from the table.
