maybe it's because you've posted it here, and not a lot of people look at this forum yet. but here you go:

Code:

---

function GetPosVecByRadious(var* SourcePos,angle,distance,var* ReturnedPos)
{
	ReturnedPos[0]=distance*cos(angle)+SourcePos[0];
	ReturnedPos[1]=distance*sin(angle)+SourcePos[1];
	ReturnedPos[2]=SourcePos[2]; 
}
..
..
..

//my rotates around you
var MyAngle=0;
var MyDistance=100;
while (1)
{
	GetPosVecByRadious(you.x,MyAngle,MyDistance,my.x);
	MyAngle+=1;
	wait(1);
}

---

this is for lite-c and rotates around the XY-plane, but you should be able to convert it easily if it doesn't suit your needs
