Summary
Function: rotation llList2Rot( list src, integer index );| 191 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a rotation 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 <span title="<0.0, 0.0, 0.0, 1.0>">ZERO_ROTATION is returned.
If the type of the element at index in src is not a rotation then <span title="<0.0, 0.0, 0.0, 1.0>">ZERO_ROTATION is returned.
Here is a workaround: (rotation)llList2String(src, index);
If the entry at index in src is not a rotation [[]] is returned (or if index is out of range).
In this case use: (rotation)llList2String(src, index);
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.
- When used to typecast from a string it will result in a ZERO_ROTATION
- A true typecast will solves this: (rotation)llList2String(src, index);
Examples

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 float=" + (string)llList2Float(my_list,i)
