== Replacing llTargetOmega with a Key Framed Motion ==
Moved to [[LlTargetOmega_Replacement]]
: This doesn't make [[llTargetOmega]] redundant but in some cases a Key Framed motion may be preferred
: [[User:Dora Gustafson|Dora Gustafson]] 05:15, 1 October 2014 (PDT)
: The routine: "KeyFrameOmega" is easy to use for [[llTargetOmega]]: It takes the first two parameters in [[llTargetOmega]]: axis and spinrate
: The included script shows how to use the routine to start, stop and reverse a spin on repeated touches
<lsl>
// llTargetOmega substitution by Dora Gustafson, Studio Dora 2014
// 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
// The parameters are the same as the two first for llTargetOmega
// 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
