Get 'y' rotation of an object and convert into vector.

A simple modified example from the scripting WIKI:

setrot(integer a)
{
vector eul = <0, 0, a>;
eul *= DEG_TO_RAD;
rotation quat = llEuler2Rot(eul);
llSetRot(quat);
}


Calling ' setrot(90); ' will set the z rotation to 90 degrees.

I also want to get the current 'y' rotation in vector form and pass it into this function.

setrot(integer a)
{
vector currot = ?????? //define currot in vector form
vector eul = <0, currot.y, a>;
eul *= DEG_TO_RAD;
rotation quat = llEuler2Rot(eul);
llSetRot(quat);
}



Basically I want to rotate an object on its z axis as defined by ' a ' while preserving the current 'y' rotation.

I could probally figure it out if the grid was online, but ah well.. Thanks in advance for your help.

Try:

vector currot = llRot2Euler (llGetRot ());

Pretty sure I tried that and got very unexpected results. I will play with it more when the grid comes back up. I'm pretty sure I can accomplish it, but I have to play with it a bit.. Thanks for your help. =)
