Summary
Function: integer llListFindList( list src, list test );| 201 | Function ID |
| 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
Caveats
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>
