|spec=
: This doesn't make [[llTargetOmega]] redundant but in some cases a Key Framed motion may be preferred
: The routine: "KeyFramedOmega" is easy to use for [[llTargetOmega]]: It takes the first two parameters in [[llTargetOmega]]: axis and spinrate
: All viewers will see the same spin and rotation
: The object will keep the rotation it has when spin is stopped
: A spin will continue even when the script is deleted
|caveats=
: The script must be in the root prim
: It can not spin child prims
: The object must be convex hull physics type
: Can not spin physical objects
|examples=
This script shows how to use the routine to start, stop and reverse a spin on repeated touches
