llList2Vector

Summary

Function: vector llList2Vector( list src, integer index );

0.0	Forced Delay
10.0	Energy

Returns a vector 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 ZERO_VECTOR is returned.
If the type of the element at index in src is not a vector then ZERO_VECTOR is returned.
Here is a workaround: (vector)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_VECTOR
  • A true typecast will solve this: (vector)llList2String(src, index);
    • Unfortunately, if it was already a vector type, using llList2String will cause the decimal values to be truncated to six decimal places.
    • In any string representation of a vector such as llList2String(src, index), or (string) llList2Vector (src, index), spaces are automatically added after the commas. When received by a listen, make sure NOT to parse by spaces.

        while(++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)
                        + "\n   key=" + (string)llList2Key(my_list,i) );
