Choose a random item from a table

Question

My goal is to pick out a random item from a table in Lua.

This is what I\'ve got so far, but it currently does not work:

local myTable = { \'a\', \'b\',          


        

Answer 1

Lua indexes tables from 1, unlike C, Java etc. which indexes arrays from 0. That means, that in your table, the valid indexes are: 1, 2, 3, 4. What you are looking for is the following:

print( myTable[ math.random( #myTable ) ] )

When called with one argument, math.random(n) returns a random integer from 1 to n including.
