Need help with rezzing/rotation!

I do have two prims linked together:

A is the root prim and rotates around its z-axis
B is linked to it and runs in a circle.

B is repeatedly rezzing a prim C, which dies after a given period of time.

My problem is, that B rezzes C at the same position all the time, instead of rezzing it relatively to B.

Being a total scripting noob, my script is simple as can be:

{
llRezObject( "C", llGetPos()+ <0.5,0.0,0.0>, <0.0,0.0,0.0>, <0.0,0.0,0.0,1.0>, 0);
llSleep(30);

llResetScript();
}

Any hint? Thanks in advance!

If you are rotating your object using llTargetOmega(), and the object is non-physical, then the position of B will never change. There's also no way to tell what position it SHOULD be in at any given time; the position is actually going to be different on every user's screen. Once you get that resolved (make your object physical or use non-physical rotation with llSetRot() or something similar), if applicable, you might then consider also calculating the rezzed object's positional offset, rotation, and/or velocity relatively:

rotation bRot = llGetRot();
vector pos = llGetPos()+BASE_REZ_OFFSET*bRot;
vector vel = BASE_REZ_VELOCITY*bRot;
rotation rot = BASE_REZ_ROTATION*bRot;
llRezObject(OBJECT_NAME, pos, vel, rot, REZ_PARAMETER);

Thanks a zillion! The code sounds totally greek to me, but hey, it works!
