Need to make that one prim faces to another and move there

Hi

All i need is that too prims comunicate each other.
One told the other its own x,y,z and then, the second prim faces it and moves there.

But, im failing at llRotLookA(

How to get the rot if i have the x,y,z of the target prim?

I was doing this, but i realise that i was messing up things:

listen( integer channel, string name, key id, string message )
{
list tokens = llParseString2List(message,[","],[]);
MyPos.x = llList2Float(tokens,0);
MyPos.y = llList2Float(tokens,1);
MyPos.z = llList2Float(tokens,2);
vector pos = <MyPos.x,MyPos.y,MyPos.z>;
vector eul = <MyPos.x,MyPos.y,MyPos.z>;
eul *= DEG_TO_RAD; //convert to radians
rotation quat = llEuler2Rot(eul); //convert to quaternion
llMoveToTarget(pos+offset*quat,.3);
llRotLookAt(quat, .1 , 1);
}

Thanks in advance for your help

Tried this one without succes

integer Channel = 12;
vector MyPos;
vector offset =<-1,0,1>;

default
{
state_entry()
{
llListen( Channel, "", NULL_KEY, "" );
}

listen( integer channel, string name, key id, string message )
{
llOwnerSay("Recibi: " + message);
list tokens = llParseString2List(message,[","],[]);
MyPos.x = llList2Float(tokens,0);
MyPos.y = llList2Float(tokens,1);
MyPos.z = llList2Float(tokens,2);
vector pos = llVecNorm(<MyPos.x,MyPos.y,MyPos.z>;
rotation rot = llRotBetween(llVecNorm(llGetPos()),pos);
//llMoveToTarget(pos,3);
llRotLookAt(rot, .5 , .5);
}
}

This works IF its physical, but i dont want it to be physical:

listen( integer channel, string name, key id, string message )
{
llOwnerSay("Recibi: " + message);
list tokens = llParseString2List(message,[","],[]);
llSay(0,llList2String(tokens,0));
llSay(0,llList2String(tokens,1));
llSay(0,llList2String(tokens,2));
MyPos.x = llList2Float(tokens,0);
MyPos.y = llList2Float(tokens,1);
MyPos.z = llList2Float(tokens,2);
vector pos = llVecNorm(<MyPos.x,MyPos.y,MyPos.z>;
vector pos1 = <MyPos.x,MyPos.y,MyPos.z>;
//llMoveToTarget(pos+offset*quat,.3);
rotation rot = llRotBetween(llVecNorm(llGetPos()),pos);
llSay(0,(string)rot);
//llMoveToTarget(<MyPos.x,MyPos.y,MyPos.z>,1);
//llRotLookAt(rot, .5 , .5);
llMoveToTarget(pos1,1.5);
llRotLookAt(rot, .5 , .5);
//llResetScript();
}

that is where it's going awry. Try this:

rotation rot=llRotBetween(<1,0,0>,llVecNorm(pos - llGetPos());


that should allow you to rotate the forward x axis of your object to point at pos. if you wish to have, say, the top Z axis, then use <0,0,1>

Yes, you are right!!

Thanks
