Lua UnPack函数用法实例

unpack它接受一个数组(table)作为参数，并默认从下标1开始返回数组的所有元素，例子代码如下：

do

 arrayData = {"a", "b", "c", "d", "e"};

 function returnMoreValues()

  return 1, 2, 3;

 end
 a, b, c = returnMoreValues();
 --print(a, b, c);
 --print((returnMoreValues()));
 --print(arrayData); -- print the address of the arrayData

 --print(unpack(arrayData)); -- print all the elements of the arrayData

 print(unpack(arrayData, 2)); --the second param is the index of the arrayData
end
