Summary

Function: vector llGetVel( );
0.0 Forced Delay
10.0 Energy

Returns a vector that is the velocity of the object.

Speed is the magnitude of the velocity. Speed is measured in meter per second.
Velocity reported is relative to the global coordinate frame (the object rotation has no affect on this functions output).

Examples

<lsl>//A very simple (and not very effective) way of keeping a physical object in place. //If you ever want to actually stop an object, use llMoveToTarget(llGetPos(), .1)

default {

   state_entry()
   {
       vector spd;
       {
           @loop;
           if (llVecMag(spd = llGetVel()) > .001)
           { //We're accelerating...
               llApplyImpulse(-spd, 0) //Slow us down.
           }
       jump loop;
       }
   }
}//Written by Xaviar Czervik</lsl>

Notes

To get the velocity relative the local frame (the direction the object is pointing), divide the output of this function by that of its rotation. <lsl>vector local_vel = llGetVel() / llGetRot()</lsl>
