look at avatar horizontal or vertical only

I'm using this:

default
{
state_entry()
{
llSensorRepeat("", "", AGENT, 20.0, PI, 0.2);
}

sensor(integer total_number)
{
llLookAt( llDetectedPos(0) + <0.0, 0.0, 1.0>, 3.0, 1.0 );
}
}

how do I get it so it only rotates horizontaly


also need another script to rotate only vertically

one prim will follow horizontally and another one will do the same but vertically

Thanks

Have you tried 'llSetStatus(STATUS_ROTATE_X | STATUS_ROTATE_Y, FALSE);'? That should allow the prim to rotate only around its z-axis. Likewise 'llSetStatus(STATUS_ROTATE_Z, FALSE);' should allow one to rotate ONLY around its z-axis. Swap axes to taste.

Otherwise, you can try to calculate a suitable rotation by hand. I find the easiest way to do this is to think about which ways you want the prim's local axes to point. For example, this should return a rotation that can be used (e.g. with llRotLookAt()) to point an object's (or child prim if you are careful about factoring in the root prim's rotation) x-axis in the horizontal direction of a point while keeping its y-axis also horizontal (not yet compiled; may require minor syntax fixes):

rotation horizontalRotPointingAt(vector targetPos)
{
   vector relativePos = targetPos-llGetPos();
   relativePos.z = 0.0;

   if (llVecMag(relativePos) < 0.01)
   {
      return llGetRot();
   }

   vector localX = llVecNorm(relativePos);
   vector localY = <-localX.y, localX.x, 0.0>;  // Same as <0,0,1>%localX; should already be a unit vector

   return llAxes2Rot(localX, localY, <0.0, 0.0, 1.0>);
}
