How fast do we go?

Does anybody know how fast we go or run?

It seems to a very high speed, since walk animations either look like you're in a silent movie or the feet slide over the ground.

/me makes a script to find out... This is on a almost-totally idle region - not sure why the numbers aren't more consistant.

From: walking
moved 3.198903 in 0.989520 = 3.232783mps
moved 3.127816 in 1.016282 = 3.077705mps
moved 3.198903 in 1.003700 = 3.187111mps
moved 3.198903 in 1.001297 = 3.194760mps
moved 2.985643 in 1.049050 = 2.846044mps
moved 2.985628 in 0.957130 = 3.119354mps
moved 3.269990 in 1.003561 = 3.258387mps
moved 3.198903 in 1.000610 = 3.196953mps

From: running
moved 5.242470 in 1.001542 = 5.234398mps
moved 4.900569 in 1.021310 = 4.798317mps
moved 5.128503 in 0.987761 = 5.192048mps

moved 4.672636 in 1.010443 = 4.624344mps
moved 5.356436 in 1.007370 = 5.317248mps

From: flying

moved 15.301110 in 1.006646 = 15.200090mps


The script...
CODE

vector  gPos;
float   gTime;

default
{
    state_entry()
    {
        gTime = llGetAndResetTime();
        gPos = llGetPos();
        llSetTimerEvent (1.0);
        
    }
    
    attach(key id)
    {
        if (id != NULL_KEY)
        {
            llResetScript();
        }
    }

    timer()
    {
        float dist = llVecDist(gPos, llGetPos());
        float time = llGetTime();
        
        if (dist > 1.0)
        {
            llOwnerSay ("moved " + (string)dist + " in " + (string)time + 
                " = " + (string)(dist / time) + "mps");
        }
        
        gPos = llGetPos();
        llGetAndResetTime();
    }
}

so we walk at about 2x speed? that explains alot. (so the optimal retime for walks would be ~0.75 to minimize both the slide effect and the speed shuffle effect.) and our run look more like a jog.

if your footfalls are twice in a second... with a pretty long stride, you don't slide.... but I do get tired watching it sometimes *blush*

Is it level ground? There is a variance when you go up or down inclines.

Advanced->HUD Info->Velocity might be useful, to rule out LSL timer idiosyncrasies.

Yep, but oddly our running speed is very ordinary, not even good enough to do a four minute mile.

It's natural for measurements based on polling the position to be off because the values only update when the client sends an update



llGetVel holds sort of steady, I got 3.19782 for walking and 5.12782 for running

Oh geez... Bit overkill with the script, I guess.. I even knew about llGetVel too..
