Summary

Function: integer llRotTarget( rotation rot, float error );

This function is to have the script know when it has reached a rotation.
It registers a rot with a error that triggers at_rot_target and not_at_rot_target events continuously until unregistered.
Returns an integer that is the handle to unregister the target with llRotTargetRemove

• rotation rot
• float error

A similar function exists for positions: llTarget
This function does not rotate the object, to do that use llSetRot or llRotLookAt.

Examples



vector standrot = <0.0, 0.0, 0.0>;
vector fliprot = <45.0, 0.0, 0.0>;

// simple two-state rot target detection and rotation by Hypatia Callisto
// works, to detect a rotation target. An example I wrote
// since there is almost zilch for clean examples for 
// at_rot_target, not_at_rot_target, llRotTarget, llRotTargetRemove

integer rottarget;

default

    rottarget = llRotTarget(llEuler2Rot(fliprot*DEG_TO_RAD), 0.1);

    llSetPrimitiveParams ([PRIM_ROTATION, llEuler2Rot(standrot*DEG_TO_RAD)]); // rotate to standrot

}
