How to make it correct?

How to make it correct?

[KT Kingsley]

You must typecast message to a vector: llMoveToTarget((vector) message,100);

And when you chat the vector you need to be careful to get it exactly right. An invalid vector in the message will be converted to the ZERO_VECTOR <0.0, 0.0, 0.0>, and your object will wander off into the distance.

After that's happened a couple of times you might want to use this code snippet to test if the message string does represent a valid vector:

integer IsVector(string s)
{
    list split = llParseString2List(s, [" "], ["<", ">", ","]);
    if(llGetListLength(split) != 7)//we must check the list length, or the next test won't work properly.
        return FALSE;
    return !((string)((vector)s) == (string)((vector)((string)llListInsertList(split, ["-"], 5))));
    //it works by trying to flip the sign on the Z element of the vector,
    //if it works or breaks the vector then the values won't match.
    //if the vector was already broken then the sign flip will have no affect and the values will match
    //we cast back to string so we can catch negative zero which allows for support of ZERO_VECTOR
}//Strife Onizuka

Also, note that the llMoveToTarget function will only work if you are wearing the object or if you have made it physical, and that it will not move an object more than 64 m.  Note also that the damping time, which you set to 100 seconds, is supposed to be a float, not an integer.  You can get away with the integer, because the compiler will typecast it implicitly, but the value really should be 100.0.

and how is the speed counted here? Is it Seconds to pass 1 meter?

–

seconds to critically damp in

[childhoodbestfriend489]

How many coordinates will and object pass through for float tau 1?

[Rolig Loon]

That depends on how far away your target is.  If your target is 10.0 m away and you have tau set to 1.0 sec, it will move 10m (unless it bumps into something, of course).

Also note that all the movement commands in LSL, other than directly setting position, are "best effort". Movement may get there. Movement may just get close. Movement may get stuck. Movement may overshoot (especially in overloaded sims). You have to check, if the final position matters.
