Summary
Function: vector llGetVel( );| 77 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a vector that is the velocity of the object.
Velocity reported is relative to the global coordinate frame (the object rotation has no affect on this functions output).
Caveats
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) //Example by Xaviar Czervik
default {
state_entry()
{
vector spd;
{
@loop;
if (llVecMag(spd = llGetVel()) > .001)
{ //We're accelerating...
llApplyImpulse(-spd, 0) //Slow us down.
}
jump loop;
}
}
}</lsl>
Notes
To get the velocity relative the local frame (the direction the object is pointing), multiply the output of this function with that of it's rotation. <lsl>vector local_vel = llGetVel() * llGetRot()</lsl>
