Summary
Function: key llList2Key( list src, integer index );189 | Function ID |
0.0 | Forced Delay |
10.0 | Energy |
Returns a key that is at index in src.
• list | src | – | List containing the element of interest. | |
• integer | index | – | Index of the element of interest. |
index supports negative indexes.
If index describes a location not in src then null string is returned.
If the type of the element at index in src is not a key it is typecast to a key. If it cannot be typecast null string is returned.
Important: Please read this intro of how to iterate over a list in LSL. |
Specification
Index | Positive | Negative |
---|---|---|
First | 0
|
-length
|
Last | length - 1
|
-1
|
Indexes
- Positive indexes count from the beginning, the first item being indexed as
0
, the last as(length - 1)
.
- Negative indexes count from the far end, the first item being indexed as
-length
, the last as-1
.
Caveats
- If index is out of bounds the script continues to execute without an error message.
Examples
// Best viewed in Chat History (ctrl-h)
default
{
state_entry()
{
list my_list = ["a", 1, 2.0, <1,2,3>, <1,2,3,4>, llGetOwner()];
integer i;
for (i=0;i<llGetListLength(my_list); ++i)
{
llOwnerSay("string=" + llList2String(my_list,i)
+ "\n integer=" + (string)llList2Integer(my_list,i)
+ "\n float=" + (string)llList2Float(my_list,i)
+ "\n vector=" + (string)llList2Vector(my_list,i)
+ "\n rot=" + (string)llList2Rot(my_list,i)
