Description

Function: list llDeleteSubList( list src, integer start, integer end );
193 Function ID
0.0 Delay
10.0 Energy

Returns a list that is a copy of src but with the slice from start to end removed.

• list src source
• integer start start index
• integer end end index


start & end support negative indexes.
While the function result is different then src, src is not modified, remember to use or store the result of this function.
The opposite function would be llListInsertList.

Specification

Index Positive Negative
First 0 -length
Last length - 1 -1

Mentally first translate any negative indexes into positive indexes

  • If start <= end then the range operated on starts at start and ends at end. [start, end]
  • If start > end then the range operated on starts at 0 and goes to end and then starts again at start and goes to -1. [0, end] + [start, -1]

Positive indexes past the length (after the last index), or negative indexes past the beginning (before the first index) are valid. The effects are predictable, the entries are treated as if they were there but were removed just before output.

See negative indexes for more information.

Examples

src = llDeleteSubList( src, start, end )

default
{
    state_entry()
    {
        // Create a list of names
        list names = ["Anthony", "Bob", "Charlie", "Dan", "Edgar", "Gerald"];
 
        // Now let's remove values at position 1 through 2.
        names = llDeleteSubList(names, 1, 2);
 
        // Result:
        // list names = ["Anthony", "Dan", "Edgar", "Gerald"];
 
        // Now let's use an start number higher then our end number
        names = llDeleteSubList(names, 3, 1);
 
        // Result:
        // list names = ["Edgar"];
    }
}
