Summary
Function: vector llGetAccel( );| 78 | Function ID |
| 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.
- Returns ZERO_VECTOR in child prims regardless of the linkset's acceleration.
Examples
//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.
}
}
