Alter an existing item in a list

[khonsuu]

I have a global list type holding 75 vectors, where each of them is a regular 3D vector.  ("Global" means it is declared outside of default{}. See below). 

I want to alter the vector that is stored at list index 24, without effecting any other items in the list nor changing the size of the list.   llList2Vector() is how you access them, but how do you write to them? 

(For those of you familiar with other programming languages outside of LSL scripting -- I am attempting to create an "array of vectors" that I can both write to and read from.)

list mylist = 
[
    <-1,-1,-1>, 
    <-1,-1,-1>,
    <-1,-1,-1>,
    .
    .
    .
    <-1,-1,-1>,
];


default 
{
    state_entry {
        etc ..
}

llListReplaceList() is what you´re looking for.

 

mylist = llListReplaceList(mylist, [new vector], 24, 24);
