Calculating speed in m/sec

If what I want to know is absolute ground speed and I use the values from llGetVel() which for example were <3.0. 4.0, 0.0>. Would I be correct that my speed is 5m/sec.? Right or wrong, how could I write the correct calculation in a script?

Thanks, Mod

llVecMag(llGetVel()) will tell you your speed.

Still not there

In a stationarly prim llVecMag(llGetVel()) comes out at <0.0, 0.0, 0.0>. Though I easly undersand that speed is 0, what I am looking for is one number that represents m/sec.

llVecMag should return a float not a vector. I can't get in world atm but see no reason to doubt your data - bug report it, it's definitely not working as advertised.

Test
03-28-2006 03:14
I did the following test:
float x = llVecMag(llGetVel()));
llOwnerSay((string) x);
and got "<0.0, 0.0, 0.0>"

Uh, if that's happening, that's an immensely serious bug (which wasn't present when I was on a few hours ago). A float should never come out as a vector. Can you post up your whole test script?

CODE
default
{
    state_entry()
    {
      float x = llVecMag(llGetVel());
      llOwnerSay((string) x);    
     }
}


Object: 0.000000


seems fine to me.

Just popped In World. llVecMag(llGetVel()) is definitely returning a float.

Maybe you did llVecNorm(llGetVel()) instead?

Here is the complete code
03-28-2006 12:33
default
{
state_entry()
{
llSay(0, "Hello, Avatar!";);
}

touch_start(integer total_number)
{
llSay(0, "Touched.";);
//vector vel = llGetVel();
float speed = llVecMag(vel);
//llVecMag(llGetVel());
float x = llVecMag(llGetVel());
llOwnerSay((string) x);
}
}

Here is the code
03-28-2006 12:39
I had to be away for a few hours but just went back in copied the code below usuing cut and paste
default
{
state_entry()
{
llSay(0, "Hello, Avatar!";);
}

touch_start(integer total_number)
{
llSay(0, "Touched.";);
//vector vel = llGetVel();
float speed = llVecMag(vel);
//llVecMag(llGetVel());
float x = llVecMag(llGetVel());
llOwnerSay((string) x);
}
}

Still get the answer <0,0,0>

Whatever was the problem, it has corrected itself.

Well, that wouldn't compile in the first place. Line 3 of the touch_start() is referring to a variable that doesn't exist, because its declaration has been commented out.

Embarrassed
03-29-2006 01:59
I want to apologize to everyone who spend time try to help with this problem. I finally discovered that I has a second script that was running and was sending the response. I should have checked for this before posting my question. I will attempt to avoid embarrassing myself and wasting your time in the future.
