llTargetOmega

Summary

Function: llTargetOmega( vector axis, float spinrate, float gain );

133	Function ID
0.0	Forced Delay
10.0	Energy

Rotates the object around axis at spinrate * llVecMag(axis) in radians per second with strength gain.

• vector	axis	–	arbitrary axis to rotate the object around
• float	spinrate	–	rate of rotation in radians per second
• float	gain	–	also modulates the final spinrate and disables the rotation behavior if zero

Specification

Physics

• If the object is not physical then the effect is entirely client side. The rotation experienced by the user cannot be detected or queried by script.
• If the object is physical then the physical representation is updated regularly. The rotation experienced by the user can be detected or queried by script.

Link Sets

• If the script is attached to the root prim, the entire object rotates around the region axis
  • If the object is attached then it rotates around the attachment axis
• If the script is attached to a child prim, the prim rotates around the local axis
  • A Child prim can rotate around its own axis while the entire object rotates around another axis.

Caveats

• If the object is not physical then the rotation is only a client side effect and it will collide as non-moving geometry.

Examples

<lsl>//rotates the x axis once per second, // rotates the y axis 3 times per second, // rotates the z axis once every two seconds. // combined the rate is about 3.20156 revolutions per second

llTargetOmega(<1.0,3.0,0.5>,TWO_PI,1.0);</lsl>

Notes

• Use llVecNorm on axis so that spinrate actually represents the rate of rotation.
• Set the gain to zero to disable and remove the rotation behavior, eg llTargetOmega(ZERO_VECTOR, 0, 0);
  • A spinrate of 0 with a nonzero gain causes the object to try to stop all spin, rather than simply clearing a previous llTargetOmega() call.
