LlDeleteSubList

Function notes

While the function result is different than src, src is not modified, remember to use or store the result of this function.

The opposite function would be llListInsertList.

Return value notes

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

Examples

src = llDeleteSubList( src, start, end )

default
{
    state_entry()
    {
        // Create a list of names
        list names = ["Anthony", "Bob", "Charlie", "Diane", "Edgar", "Gabriela"];
        
        // Now let's remove values at position 1 through 2.
        names = llDeleteSubList(names, 1, 2);

        // Result:
        // list names = ["Anthony", "Diane", "Edgar", "Gabriela"];
        
        // Now let's use an start number higher then our end number
        names = llDeleteSubList(names, 3, 1);
        
        // Result:
        // list names = ["Edgar"];
        // If start number higher then our end number, then we should imagine that the start and the end are missing before start and end.
        // Imagine it should be FROM_THE_LISTSTART_CUT: start, AND_FROM_THE_LISTEND_CUT: end ... more or less :))
        // names = llDeleteSubList(names, 3 -> , <- 1);

    }
