my brain hurts ~.~ :P
anyways, what im having problems with is i need to get a vector (velocity from llRezObject. The Object is rezzed from an attachment) so point to a detected avatar.
I was looking over the wiki and couldnt find anything, and rotations make my brain hurt lol.

If anyone knows how to find this i would greatly appreciate it. :)

CODE
sensor(integer n)
{
    vector relative_pos  = llDetectedPos(0) - llGetPos();
    rotation rot_2_detected = llRotBetween(llVecNorm(relative_pos), <1.0, 0.0, 0.0>);

    // This will rez "object" one meter away from you in the direction of the first thing detected, moving at one meter per second toward that detected thing, with the X-Axis of "object" pointed at that detected thing.
    llRezObject("object", llGetPos() + (<1.0, 0.0, 0.0> * rot_2_detected), <1.0, 0.0, 0.0> * rot_2_detected, rot_2_detected, 0);
}

hmmm, doesnt seem to work :( it shoots it, but its not even close to be shooting in the direction of the person.

CODE
  
	sensor(integer num_detected)
	{
		integer i;
		for(i=0;i<num_detected;i++)
		{
			vector relative_pos  = llDetectedPos(i) - llGetPos(); 
			rotation rot_2_detected = llRotBetween(llVecNorm(relative_pos), <1.0, 0.0, 0.0>); 
			Debug((string)relative_pos + " | " + (string)rot_2_detected);
			// This will rez "object" one meter away from you in the direction of the first thing detected, moving at one meter per second toward that detected thing, with the X-Axis of "object" pointed at that detected thing. 
			llRezObject(object, llGetPos() + (<1, 0.0, 0.0> * rot_2_detected), <1.0, 0.0, 0.0> * rot_2_detected, rot_2_detected, 0); 
		}
	}

ooops, I think I screwed up and reversed something :).

this: rotation rot_2_detected = llRotBetween(llVecNorm(relative_pos), <1.0, 0.0, 0.0>;);

should have been...

this: rotation rot_2_detected = llRotBetween(<1.0, 0.0, 0.0>, llVecNorm(relative_pos));

CODE
sensor(integer n)
{
    vector relative_pos  = llDetectedPos(0) - llGetPos();
    rotation rot_2_detected = llRotBetween(<1.0, 0.0, 0.0>, llVecNorm(relative_pos));

    // This will rez "object" one meter away from you in the direction of the first thing detected, moving at one meter per second toward that detected thing, with the X-Axis of "object" pointed at that detected thing.
    llRezObject("object", llGetPos() + (<1.0, 0.0, 0.0> * rot_2_detected), <1.0, 0.0, 0.0> * rot_2_detected, rot_2_detected, 0);
}


or for your code...

CODE
  
	sensor(integer num_detected)
	{
		integer i;
		for(i=0;i<num_detected;i++)
		{
			vector relative_pos  = llDetectedPos(i) - llGetPos(); 
			rotation rot_2_detected = llRotBetween(<1.0, 0.0, 0.0>, llVecNorm(relative_pos)); 
			Debug((string)relative_pos + " | " + (string)rot_2_detected);
			// This will rez "object" one meter away from you in the direction of the first thing detected, moving at one meter per second toward that detected thing, with the X-Axis of "object" pointed at that detected thing. 
			llRezObject(object, llGetPos() + (<1, 0.0, 0.0> * rot_2_detected), <1.0, 0.0, 0.0> * rot_2_detected, rot_2_detected, 0); 
		}
	}
