Point to target (NOT llLookAt!)

Hey everyone. I'm trying to find a formula or function or something that will determine which rotation will cause the object to point at a specified target.


Basically llLookAt, but with the X axis instead of the Z axis.


Thanks in advance



P.S. It could be dealing with long ranges, so it needs to be fairly precise...



EDIT: I suspect it could involve switching the X and Z coordinates or something... Not entirely sure.

Check in the old wiki, at http://rpgstats.com/wiki/index.php?title=LlLookAt

The sample script there shows you how to use llRotLookAt with any axis.

vector lookat; // coordinates of point to look at
default
{
    state_entry()
    {
        llSetRot( llRotBetween( < 1.0, 0.0, 0.0 >, llVecNorm(lookat-llGetPos())));
    }
}

Enjoy

Thanks. Very helpful ^_^
