LlRotTarget

{{LSL_Function |func_id=68|func_sleep=0.0|func_energy=10.0 |func=llRotTarget |return_type=integer |p1_type=rotation|p1_name=rot|p1_desc=target rotation |p2_type=float|p2_name=error|p2_desc=angle in radians, defines when rot has been reached |func_footnote=A similar function exists for positions: llTarget
This function does not rotate the object, to do that use llSetRot, llRotLookAt or llLookAt. |func_desc=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. |return_text=that is the handle to unregister the target with llRotTargetRemove |spec |caveats |constants
