Sitting and making AV face a certain direction.

I want to make the avatar sit and rotate towards a particular direction. I put this code in the prim that the AV sits on.

default
{
state_entry()
{
llSetText("Sit",<255,255,255>,1.0);
llSetSitText("Sit";
llSitTarget(<0,0,0>, llEuler2Rot(<0,0,180>);
}

}

Of course this doesn't work since it is always rotating 90o. Is there a way to make the AV sit but face a certain direction?

"Face a certain direction" locally or globally? Locally is easy, just pass the desires direction as a rotator to llSetSitTarget. But note that llEuler2Rot expects angles measured in radians, not degrees. PI rad == 180 deg.

For global directions, you'll have to divide the desired rotation by the object's rotation.

llSetSitTarget requires a NON ZERO vector to take effect.

llSitTarget(<0,0,0>,<some rotation>; will NOT work.

llSitTarget(<0,0,0.01>,<some rotation>; will work.

D'oh! That one slipped right past me. That's what I get for posting in a state of near-unconsciousness.

The rotation should be in radians, not degrees.

180*DEG_TO_RAD

or

llEuler2Rot(0,0,PI_BY_TWO);
EDIT::
wait pi by two is 180 isnt it? SO..PI

lol

It helps knowing about the NON_ZERO vector. However I want to know if I my AV sits on say a chair I make, how do I tell it (or the chair) to always sit correctly (e.g. AVs back facing back of chair) no matter which way the chair is facing.

Is the llSitTarget() enough or do I need to always take into account chair orientation.

Try getting the local rotation or the chair first using llGetLocalRot, store this in a variable and then use that for the rotation.

This is getting a little confused. The rotation specified in llSitTarget is relative to the prim, as Deanna mentioned. So the script doesn't need to adjust that rotation when the chair rotates in order to keep the avatar facing the same direction relative to the chair.

(It *would* have to do that, however, if the avatar was always supposed to face East, say. Or if the prim containing the llSitTarget rotated locally relative to the rest of the chair but the avatar's rotation was to remain constant relative to the rest of the chair rather than to the prim on which he's sitting. But this doesn't seem to be either of those rather special cases.)

You can see this for yourself when you adjust a poseball, for example. When your avatar sits on the poseball it adopts the rotation specified in the poseball's llSitTarget. When you rotate the poseball, your avatar rotates with it, while the llSitTarget remains the same.

sit target position and rotation are offsets which add to the objects current position and rotation. No need to worry about the object position/rotation.
