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:
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
