[away3d] Re: Angle between two objects

[Li]

I'm not sure if there is a native method, but something like this should
work (based on the dot product of 2 vectors):

var obj1Vector:Number3D = obj1.position;
var obj2Vector:Number3D = obj2.position;
var cosAngle:Number =
obj1Vector.dot(obj2Vector)/(obj1Vector.modulo*obj1Vector.modulo);
var angle:Number = Math.acos(cosAngle);

This will be the angle between the positional vectors of the objects in the
plane they define.
I'm not sure what you mean by Y-angle, but just post more details if this
doesn't help you.
