simple query

I have this code:


llRezObject("ROV2", llGetPos() + <-2.0,-4.0,2.0>, <0.0,0.0,0.0>, <0.0,0.0,0.0,1.0>, 0);

I want ROV2 to rez at 270 degrees on the z axis which one do I alter???

The rotation is this one: <0.0,0.0,0.0,1.0>

but it's in quaternions, which most mere mortals don't find possible to translate into normal X Y Z axes. Fortunately there's an LSL function to convert, llEuler2Rot

http://www.lslwiki.net/lslwiki/wakka.php?wakka=llEuler2Rot

You probably want something like this:

llRezObject("ROV2", llGetPos() + <-2.0,-4.0,2.0>, <0.0,0.0,0.0>, llEuler2Rot(<0,0,270>, 0);

*edit* the forum mangles this a bit as I look at it, it should be all in one line

although I'm not in world to test so ymmv. Hope that helps some.

That wont work, you have to convert the vector DEGREES to RADIANS first....

vector myVect = <0,0,270>;
myVect *= DEG_TO_RAD;
rotation myRot = llEuler2Rot (myVect);
llRezObect ("ROV2", llGetPos() + <-2,-4,2>, <0,0,0>, myRot),0);

Thanks Johan, I should have known I'd forget something obvious in my haste.

edit: or you could always just express the rotation in terms of pi

Yeah, I'd never even heard of quaternions before SL, (and you think you've heard of everything at some point), and quaternions are still a mathematical mystery to me, so, me, llRot2Euler() and llEuler2Rot() are good buddies, so I caught that pretty quick
