Here is the list of number. 1,2,3,4. To pick one of them randomly, I can simply type in the action window like "int(random(0,4))+1", or "choose(1,2,3,4)". Now, player unlocks some objects, and now the list of number changed : 1,2,3,4,7,10,16. Now what should I do? The list can be changed with any number, and the size of the list also varies. What I'm thinking is like "choose(list)" but I have no idea how to make it work.
