LlRotTarget

Wiki description

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.

Function notes

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

Return value notes

Returns an integer to unregister the target with llRotTargetRemove

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
{

    state_entry(){ 
        rottarget = llRotTarget(llEuler2Rot(fliprot*DEG_TO_RAD), 0.1);
        llSetPrimitiveParams ([PRIM_ROTATION, llEuler2Rot(standrot*DEG_TO_RAD)]); // rotate to starting point
    }

    not_at_rot_target()
    { 
        llRotTargetRemove( rottarget );
        llOwnerSay("not there"); //not at target
    }
        
    touch_start (integer total_number)
    {
        state rotatestate; // change to state for new position
    }
}
             
      
state rotatestate 
{ 
    state_entry(){ 
        rottarget = llRotTarget(llEuler2Rot(fliprot*DEG_TO_RAD), 0.1);
        llSetPrimitiveParams ([PRIM_ROTATION, llEuler2Rot(fliprot*DEG_TO_RAD)]); // rotate to new point
    }
    
    at_rot_target(integer tnum, rotation targetrot, rotation ourrot)
    { 
        llRotTargetRemove( rottarget );
        llOwnerSay("there"); //reached the target
    }

    touch_start(integer touched){ 
        state default; 
    }
    
}
