Description
Constant: integer PRIM_OMEGA = 32;The integer constant PRIM_OMEGA has the value 32
Used to make the object spin at the specified axis and rate, or retrieve spin settings. See llTargetOmega for specification.
llSetPrimitiveParams
[ PRIM_OMEGA, vector axis, float spinrate, float 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 |
When used with llSetPrimitiveParams & llSetLinkPrimitiveParams
llGetPrimitiveParams
llGetPrimitiveParams([ PRIM_OMEGA ]);Caveats
- PRIM_OMEGA on nonphysical objects, and child prims of physical objects, is only a client side effect; the object or prim will collide as non-moving geometry.
- PRIM_OMEGA cannot be used on avatars sitting on the object. It will emit the error message "PRIM_OMEGA disallowed on agent".
- If PRIM_OMEGA does not appear to be working, make sure that that Develop > Network > Velocity Interpolate Objects is enabled on the viewer.

Examples
// Set this prim rotating
llTargetOmega(<1.0,3.0,0.5>, TWO_PI, 1.0);
// Read back this prim's current target omega
list current_omega = llListToList( llGetPrimitiveParams([PRIM_OMEGA]); // should be [PRIM_OMEGA, axis, spinrate, gain]
vector axis = llList2Vector(current_omega, 1); // Should be <1.0,3.0,0.5>
float spinrate = llList2Float(current_omega, 2); // Should be TWO_PI
float gain = llList2Float(current_omega, 3); // Should be 1.0
// Set all child prims rotating
llSetLinkPrimitiveParamsFast(LINK_ALL_CHILDREN, [PRIM_OMEGA, <1.0,3.0,0.5>, TWO_PI, 1.0]);
Also, can use llSetPrimitiveParams for the root prim.
// will need two prims linked together for this script.
