llListFindList

Summary

Function: integer llListFindList( list src, list test );

0.0	Forced Delay
10.0	Energy

Returns an integer that is the index of the first instance of test in src.

• list	src
• list	test

If test is not found in src, -1 is returned.
The index of the first entry in the list is 0
If test is found at the last index in src the positive index is returned (5th entry of 5 returns 4).

Caveats

• Strict type matching and case sensitivity is enforced.

Examples

<lsl>list numbers = [1, 2, 3, 4, 5]; default {

   state_entry()
   {
       integer index = llListFindList(numbers, [3]);
       if (index != -1)
       {
           list three_four = llList2List(numbers, index, index + 1);
           llOwnerSay(llDumpList2String(three_four, ","));
           // Object: 3,4
       }
   }

}</lsl>

Useful Snippets

An easy way to see if an item exists in a list... <lsl>if(~llListFindList(myList, (list)item)) {//it exists

   //This works because ~(-1) == 0
   //It saves bytecode and is faster then doing != -1

}</lsl>
