Periodic X and Y rotation

So, I'm making a flying saucer. Just to teach myself how to do stuff.

I presently have two scripts in the root of this thing. One is a simple llTargetOmega that spins the saucer on it's Z axis, and another that uses llSetBuoyancy to let the thing float up and down a bit. So far, so good.

Here's where I have the issue. When floating about, it will occasionally hit the floor, bounce a bit, and travel off in some horizontal direction. That's fine, but it will inevitably bump something and end up a bit sideways. I'd like it to right itself every few seconds in case this happens.

I tried the simple solution first:

default
{
    state_entry()
    {
        llSetTimerEvent(3);
    }
 
    timer()
    {
        llSetRot( ZERO_ROTATION );
     }
}

This does nothing at all. Afterwards, I started fooling with vectors, llEuler2Rot, and so forth. Nothing works.

All I want this thing to do is rotate the object on its X and Y axii to 0 every few seconds. Help?

Have you waded through the stuff on the wiki? Bound to be pointers in there:

Seems to be the root prim of a physical object (llSetBuoyancy, bouncing around), so you might want to try llRotLookAt() instead. Or something like:

llSetStatus(STATUS_ROTATE_X | STATUS_ROTATE_Y, FALSE);

Probably have to try it out in your application to decide which has the lesser effect on the "naturalness" of the motion.

Look at "The Vertical Attractor" section at:

It talks about what boats use to keep their "up-side up". I think this is the sort of behavior you are looking for. That way, you'd be able to control how much the saucer wobbles before righting itself.

Stupid forums, wouldn't let me reply. > I can't post the code, not even inside php tags.

llRotLookAt() did the trick. I didn't look at this function yet, but the answer was right there in the wiki.


Thank for the suggestions.

Look at every vector and rotation in your script and add a space after the opening bracket:
< 0,0,0>, < 0,0,0,1>
works! Take the space out and you can not post.

I'm pretty sure that llSetRot is ignored on objects that are physical..

Sheesh.

default
{
    state_entry()
    {
        llSetTimerEvent(3);
    }
 
    timer()
    {
        //llSetRot( ZERO_ROTATION );
        vector eul = < 0,0,FALSE> ; //we dont care about the z axis anyway
        eul *= DEG_TO_RAD; //convert to radians
        rotation quat = llEuler2Rot(eul); //convert to quaternion
        
        llRotLookAt( < quat.x, quat.y, FALSE, 1>, 0.2, 1 );
     }
}

Glad to see you have it figured out with my incomplete instructions!

I forgot to add that you need to do all of that , while keeping in mind the SQL keywords AND while standing on one foot only with a North/South orientation of the foot that is in the air.

What is the purpose of using "FALSE" in these locations? It is not treated by the compiler as anything different from the constant zero.
