Trying to get llRezAtRoot vector from Object description

Been tring it different ways but still can't get it to read the description into the vector field. It does compile but it doesn't do anything. Any suggestions?:

llRezAtRoot(llGetInventoryName(INVENTORY_OBJECT, 0), (vector)llGetObjectDesc(), ZERO_VECTOR, ZERO_ROTATION, 42);

Well, the simplest answer to this is that llGetObjectDesc is going to return a string. You cannot directly convert a single string to a vector since it requires 3 separate variables.

The resolution? You will need to parse the string to a list first.

It could be that the vector you're entering into the description is not in region coordinates, you may be asking it to rez at <0,0,1>, which means in the very south west corner of the sim at a height of 1 meter. If the rezzing object is not within 10m of there it'll fail silently.

Tiarnalalon is incorrect, I use vector positions in object descriptions all the time, (vector)llGetObjectDesc() works fine.

I use "llSetObjectDesc( (string)llGetRootPosition() );"which will set the description like this:
<40.57762, 246.15448, 63.68597>

So it has to be somewhere in the way I worded it. It works just fine if I copy the description and paste it into the vector field like this:

llRezAtRoot(llGetInventoryName(INVENTORY_OBJECT, 0), <40.57762, 246.15448, 63.68597>, ZERO_VECTOR, ZERO_ROTATION, 42);

I dunno what you're doing wrong, this works fine for me:

default
{
    state_entry()
    {
        llSetObjectDesc( (string)llGetRootPosition() );
    }

    touch_start(integer total_number)
    {
        llRezAtRoot(llGetInventoryName(INVENTORY_OBJECT, 0), (vector)llGetObjectDesc(), ZERO_VECTOR, ZERO_ROTATION, 42);
    }
}

Try this just for debugging purposes, to see what's happening:

string item = llGetInventoryName(INVENTORY_OBJECT, 0);
string strvec = llGetObjectDesc();
vector pos = (vector)strvec;
llSay(0, "Rezzing: " + item + " at " + strvec + ", aka " + (string)pos);
llRezAtRoot(item, pos, ZERO_VECTOR, ZERO_ROTATION, 42);

Hey this is wild!!!!!:

errrr nevermind I caught myself there. I need to read the inevntories object description field. Reading objects description reads the prim the script is sitting in.
