llListRandomize

Summary

Function: list llListRandomize( list src, integer stride );

0.0	Forced Delay
10.0	Energy

Returns a list which is a randomized permutation of src.

• list	src	–	A list you want to randomize.
• integer	stride	–	How many list entries to keep next to each other during the randomization.

Specification

When you want to randomize the position of every list element, specify a stride of 1.

If the stride is not a factor of the list length, the src list is returned. In other words, src.length() % stride must be 0.

Conceptually, the algorithm selects src.lengh()/stride buckets, and then for each bucket swaps it the contents with another bucket.

Examples

list straws = ["long", "long", "long", "short"];
list shuffled = llListRandomize(straws, 1);
llSay(0, llList2CSV(bar));
