Summary

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

Returns a vector that is the acceleration of the object in the region frame of reference.

Caveats

  • Returns ZERO_VECTOR in attachments regardless of the avatar's acceleration.

Examples

<lsl> //A very simple (and not very effective) way of keeping a physical object in place. //If the object is moving when the script is put in the object, then the object will continue to move, so long as it doesn't accelerate. //If you ever want to actually stop an object, use llMoveToTarget(llGetPos(), .1) default {

   moving_start(){ 
       vector ac;
       // Go forever         
       while(llVecMag(ac = llGetAccel()) > .001) { //We're accelerating...
           llApplyImpulse(-ac, 0); //Slow us down.
       }
   }
}</lsl>
