Detect when a GameObject is facing another?

[exiguous]

Getting the angle between 2 objects

I prefer: var something : Transform; // position of the other object var p : Vector3 = transform.InverseTransformPoint(something.position); Now p is the position of something in my local coordinate space. If p.y > 0, it’s above me. If p.x < 0 it’s to my left. If p.z < 0 it’s behind me. Very convenient for writing any kind of AI code.
