I am in need of help

I have a somewhat simple problem. I would like a user to say "height XXX" and have an object move to that position. Any idea on how I could do this? I was thinking llsetpos but from what I read, that has it's limits.

llSetPos has a limit of 512m in total height and 10m of movement per 0.2 seconds.

list listmessage = [];
vector loca;
float ground;

GoTo(vector dest)
{
    ground = llGround(ZERO_VECTOR);
    if(dest.z > 512)
    {
        llSay(0,"Error! Can not go that high!");
    }
    else if(ground > dest.z)
    {
        llSay(0,"Error! Ground only " + (string)ground + " high!");
    }
    else while(dest != llGetPos())
    {
        llSetPos(dest);
    }
}

default
{
    state_entry()
    {
        llListen(0,"",NULL_KEY,"");
    }
    listen(integer channel,string name, key id, string message)
    {
        listmessage = llParseString2List(message,[" "],[]);
        if(llList2String(listmessage,0) == "height")
        {
            loca = llGetPos();
            GoTo(<loca.x,loca.y,llList2Float(listmessage,1)>);
        }
    }
}

I didn't put in a check for the ground height, but... *shrug* I'm lazy. EDIT: Ok, I put the ground height check in, because I hate doing a half-assed job. EDIT2: Because everything in LSL is fucked up and some things take offsets while others take global coords with no rhyme or reason whatsoever.

Mol, llGround accepts an offset from the object's current position. llGround(llGetPos()) doesnt actually get the ground height at the location the object is currently at. llGround(ZERO_VECTOR) would do that.

(Unless something has changed since Ive been gone )

Very good, only problem was when I re-rezed it, it moved back to where it was before, easy fix... llGetpos() in state_entry.

There. Fixed it so it works right. Stupid LSL.

My fix did not work :/ after using height, you will never be able to use it again.

Whaaat? You sure about that? Lemme go check.

EDIT: You must be using some other script at the same time in there or something. I copy/pasted that into an object, left it EXACTLY the way it was, no editing whatsoever, and it worked fine, even if I Took it and re-rezzed it.
