Damp
Damping, represented by a
tau symbol for
seconds, is a type of
physical motion characterized by its non-constant velocity: the closer the
object is to its
target, the slower it will go. Because of this property of
damped motion,
damping is used in a few
LSL dynamics movement
functions to compensate for rounding errors and
script asynchronicities.
Damping relies on the principle that a slow-moving object is easier and more visually appealing to stop than a fast-moving one.
With Havok 2, damping will (hopefully) become less of an issue then it is now, and constant velocity motion, while still slightly more difficult to code, will become more accurate, and therefore more appealing.
Functions that cause
damping include:
llGroundRepel
llLookAt
llMoveToTarget
llRotLookAt
llSetHoverHeight
