Rotation Problems

Hello, I've made a little thing that I want to rotate correctly no matter the direction its facing. I figured out how to get it to look at the direction its facing, but figuring out how to get it to correct itself automatically is something I don't know how to do.

For instance I want to rotate it to 45 degrees, right now I have to click it to get it to correct itself.

I don't know what to look for as far as documentation goes on how to do this. Can somebody help with a place to go to on how to do this?

Thank you

default
{
    state_entry()
    {
        llTargetOmega(<0,0,0.1>*llGetLocalRot(),PI,1); 
    }

    touch_start(integer total_number)
    {
        llResetScript();
    }
}

You'll need to take out the root rotation, which is why it goes wrong when you rotate the object away from <0,0,0>:

llTargetOmega(<0,0,0.1>*llGetLocalRot()/llGetRootRotation(),PI,1);
