函式: llApplyImpulse( vector force, integer local );

Applies impulse to object

• vector force
• integer local boolean, if TRUE, force is treated as a local directional vector instead of region directional vector.

Instantaneous impulse. llSetForce has continuous push. "Instantaneous" seems to mean a one second impulse, as an application of a force (in newtons) equal to the object's mass (in kg) for one second will accelerate it to a velocity of 1 (in meters per second), which appears to be what happens with this function.


  • Object must be physical.
  • The force magnitude is capped at 20.000.
  • The force magnitude is scaled by the object's energy.
